Looking back at 80 years of smartwatch development with notable milestones
From the initial idea to the development of a popular wearable device today, smart watches have gone through a rather arduous but equally interesting journey. 24h Technology will give you an overview of the history of smart watches, provoking discussions about old and new technology through the article below. Many companies such as Apple, Samsung, Xiaomi have invested millions of dollars in smart watch technology in recent years. Although controversial, this product is still developing strongly at the present time.However, the idea of smart watches is not new. In fact, its history began a few decades ago, when computer technology was in its infancy. So when did the history of smart watches actually originate? Let's take a look at the stages of development of this product. The History of Smartwatches: The BeginningThe history of smartwatches is full of interesting stories, and one of the first chapters belongs to the Mimo-Loga, a revolutionary device created in 1940 by Swiss watchmaker Huguenin Frères. This is a complex mechanical device with two rotating bezels, integrated with logarithmic and tachymeter scales. This allows users to perform complex mathematical calculations such as multiplication and division, square root, unit conversion, speed calculations, and more. Mimo-Loga was originally designed for pilots, helping them perform necessary calculations while flying. However, with its high applicability, it quickly became popular with engineers, architects, scientists, and people working in fields that require precise calculations.This timekeeping feature also had a profound impact on the history of smartwatches because it paved the way for the birth of watches equipped with electronic calculators.Most famously, we have to go back to 1972, when Hamilton Watch Company and Electro/Data Inc developed the first digital watch, a prototype called Pulsar that used LEDs and was crafted from 18-karat gold. The Pulsar was priced at $2,100. Adjusted for inflation, this is equivalent to $15,121 in 2023. Although users could only display the calculated numbers, Pulsar truly revolutionized the watch industry and paved the way for the development of smart watches later on. It can even be said that this is an important milestone in the history of smart watches.Sensing the potential of this 'smart watch', not long after, many Japanese companies began experimenting with methods of adding content to watches, allowing users to enter or view different types of data. And Seiko was one of the first pioneers in this field, from 1970 to 1990, the company launched many electronic watch models with many new features.Among them, the watch model that created the biggest buzz was probably the famous T001 in 1983, which appeared in the James Bond movie "Octopussy". The watch is connected to a portable TV receiver, while the 0.25-inch display is divided into two separate areas. The top area is for the usual watch features like displaying the time and setting alarms, while the bottom is used for video output, although the image quality is quite low. At the same time, Seiko launched the Data 2000, named after its ability to store 2,000 characters via an external keyboard. Just one year later, its sibling, the RC-1000, was born with a breakthrough feature that could connect to most popular computers at that time. By connecting the RC-1000 to a Commodore 64 or Apple II, users could interact with the watch and share information.However, if we compare it to modern smartwatches, the RC-20 Wrist Computer is the watch with many of the features that smartwatches still use today. This small watch is equipped with an 8-bit Z-80 processor, 2KB RAM and 8KB memory. The RC-20 Wrist Computer has calendar, note, time zone and calculator applications.The Rise of the Complete SmartwatchThe 2000s marked the beginning of the smartwatch industry with a series of complete smartwatch models such as SPOT, PDA and wireless connectivity, as well as the appearance of USB connectivity.The First Complete SmartwatchHowever, the beginning of it all would be in 1994 with the appearance of the Timex Datalink - the first watch capable of downloading data from a computer wirelessly. By illuminating the computer screen with a flashing display, the watch could encode information to be transmitted via sensors inside the watch. Datalink was a pioneer of scientific innovation, even used by NASA in space missions. It was also Microsoft's first foray into the market.The first smartwatch running LinuxNext, pioneering inventor Steve Mann designed and developed the first Linux-powered smartwatch in 1998. After introducing the watch, he was hailed as the "father of wearable computing," a title that was well-deserved for his contributions to the field.Mann has made many other important contributions to modern technology, including being the first to develop modern HDR photography.The first smartwatch that could make phone callsSamsung was one of the first companies to introduce a smartwatch running the Android operating system. The company was also the first to develop a watch with telecommunication capabilities in 1999 with the SPH-WP10, which featured a monochrome LCD display and supported 90 minutes of talk time with a built-in speaker and microphone. Although Samsung stopped making smartwatches shortly after, they quickly reinvested in the industry when they realized its potential a few years ago.2000: IBM's effortsIn 2000, IBM unveiled a prototype Linux-powered smartwatch called the WatchPad. Although the original version had many limitations, the company quickly upgraded it to create a better version. In 2001, the IBM WatchPad 1.5 was released with an accelerometer, fingerprint sensor, and vibration. It also ran on Linux 2.2, had a 320 x 240 QVGA touchscreen, Bluetooth, 8 MB RAM, and 16 MB flash memory. This was a major breakthrough that paved the way for the entire industry, but mobile technology at the time was not good enough to make it a reality.2002: Fossil and the PDA EraAlthough today's young people may not remember these devices, PDAs were very popular in the early 2000s. Therefore, Fossil decided to launch a unique device called the Wrist PDA, which was truly a revolutionary device, which can be considered the precursor to modern smartwatches later on. The Wrist PDA was capable of exchanging data with a PC, and also featured a virtual keyboard, a touchscreen, an infrared port, and a small stylus for more efficient user interaction. Tech reviewers at the time praised the product’s innovation, including the ability to use a variety of applications within Palm OS.Microsoft’s Mistake in 2004 and the Birth of a New IndustryIn 2004, Microsoft re-entered the market with the SPOT (Smart Personal Objects Technology) smartwatch. The entire project was actually a precursor to wearables and IoT, which aimed to personalize technology. Unfortunately, Microsoft made some bad decisions in this endeavor, including closing the network to its own ecosystem, which led to an unsurprising end. Since then, a number of companies have tried their hand at smartwatches, although most of their efforts have been too niche or impractical to appeal to a mass audience.In 2012, Pebble truly changed the world of Kickstarter and the wearables market, marking a turning point in smartwatch history when their $10 million campaign showed that there was a real need for such devices from major tech companies.In 2013, Omate was the first company to design a truly standalone smartwatch. The TrueSmart could make calls, use maps, and take advantage of Android apps completely independently. While their Kickstarter campaign was full of missteps, it was a milestone that marked the development of the smartwatch industry as it is today. What do modern smartwatch models have? At present, the smartwatch manufacturing industry has become a huge 'cake' that many manufacturers are competing for such as Apple, Samsung, Xiaomi,... Along with that, a series of new generation smart watch models are competing to launch.So, what are the most outstanding features that modern smartwatch models have? With advanced sensors and smart software, modern smart watches can help you monitor and improve your health comprehensively thanks to features such as: Measuring blood pressure, monitoring sleep, measuring blood oxygen levels (SpO2),... that almost all smart watch models from cheap to high-end have. Not to mention that modern smartwatch models are also quite diversely stratified, from high to low prices, age, gender, etc. In addition to popular models, there are also watches distributed specifically for sports activities thanks to specialized features. In the future, I believe that there will be many, many other new generation smartwatch models that will be continuously developed, and I also hope that in the future I will be able to admire many more new features. Personally, I hope that in the future, watches can emit holograms like in science fiction movies, what about you? What features do you hope will appear on future smartwatches?ConclusionMore than 8 decades have passed since the first 'smartwatch' was born. From the basic prototype with a logarithmic scale engraved on the bezel, to complex machines with countless capabilities to bring users increasingly complete experiences.

How many types of watch glass are there?
What types of watch glass, advantages of each type of glass?Currently, there are several main types of watch glass as follows:– Sapphire glass: The most expensive and most scratch-resistant type of watch glass– Mineral glass: This type of glass is cheap but cannot resist scratches when rubbed or collided.– Acrylic glass 1. Mica glass (Acrylic glass)- In fact, this is not glass but a type of transparent synthetic plastic, this type is often used in hompage models or old watches such as Poljot, Omega hompage... because this type of face has natural transparency, looks quite beautiful. In addition, the convex surface - a characteristic of Mica glass - helps to enhance the face of the watch, the feeling of the watch face is quite close and classic, a point that many watch players love.2. Sapphire glass (Sapphire glass)This is a type of transparent glass with a hardness only lower than diamond on the hardness scale (about 2000 VK, diamond is 10000 VK). Therefore, it has very good scratch and impact resistance. Very good but does not mean perfect, they can still be scratched when you rub a diamond on it or rub sapphire on sapphire or the edge of a rice leaf on the sapphire glass will be scratched. Sapphire is divided into 03 small types as follows:Thin coated sapphire:This is a type of glass that is usually coated with a thin layer of sapphire. This type of glass is brittle and easily broken when impacted even very lightly. Because of its nature, glass is usually the least hard of all types. This type is often used for cheap imitation watches. When used for a while, it gets scratched because after a few months of use, the sapphire layer fades away, leaving only regular glass. And at that time, just a light stroke is enough to scratch it immediately.Thick coated sapphire:This type is similar to the above type but is coated thicker so it can be used longer before being scratched.Sapphire block:- This is the best type of sapphire glass, with a hardness second only to diamond. This glass has extremely good scratch resistance, can grind concrete without scratching. Usually only genuine watches have this glass installed. Because this type of glass is quite expensive.- The higher the hardness, the better the scratch and impact resistance. Some people think that sapphire glass is brittle and easy to break, but that is not true. Sapphire glass has the best impact resistance among all types of glass if the same size.3. Mineral glass - Mineral Glass is actually a regular glass, which is less hard than Sapphire glass (400 VK), so it is more susceptible to scratches and breakage, but has the advantage of being easy to polish like new.- Mineral glass is cheap, so it is quite commonly used for mid-range watches such as Casio, Orient or Citizen. Because it is cheap, people often make thick glass, which helps its impact resistance better than a thin sapphire. * Note for use:- A watch with a scratch-resistant sapphire glass is very good, but no sapphire glass is perfectly scratch-resistant, so you should not throw or toss the watch into the drawer every time you do not use it, but it is better to store it carefully or wrap it in a soft cloth for the watch. The more careful you are, the more durable and scratch-resistant the watch will be.- Genuine watches, even if they use sapphire glass, are thick and of high quality, so they can be used for a long time before being scratched.- For watches with too many scratches and cracks, you should replace them as soon as possible because those cracks and breaks can cause dirt to stick deep into the engine or watch hands, reducing its accuracy due to resistance.- If you keep your watch with other jewelry, you should store it separately in a place with a soft surface and designed specifically for watches, because if you put them together, it can scratch the watch or other jewelry. Especially the glass surface, the stone edges of other jewelry, they are materials that are incompatible with sapphire glass.Wish you use and preserve your beloved watch well.

Unlocking the Truth About Blood Sugar
All of us should have gone to the hospital for a checkup, and the day before the checkup, the doctor will instruct you to remember not to eat breakfast tomorrow. Therefore, when we go to the hospital for a checkup, the blood sugar we measure is fasting blood sugar. So if I measure a normal fasting blood sugar, does that mean I don't have diabetes? What are the warning signs of diabetes besides the blood glucose level? 1. Do you really know about diabetes? The incidence of diabetes is very high, it is mainly due to the body's insulin secretion, or insulin secretion defects, caused by the metabolic abnormality of sugar, protein, fat, resulting in chronic elevation of blood glucose, the human body caused by acute and chronic organ damage. There are many complications caused by diabetes, which can be said to affect every organ of the body from head to toe. For example, retinopathy, diabetic nephropathy, diabetic cerebrovascular disease, coronary heart disease myocardial infarction, lower extremity macrovascular disease, neuropathy. This causes our eyes to lose vision, blindness, diabetic foot and even amputation, the disability rate is very high. 2. Fasting blood sugar is normal, no problem? We have to measure the fasting blood glucose once a year in the physical examination, many people think that the fasting blood glucose is normal and there is no problem, in fact, it is the lack of knowledge of diabetes. The diagnostic criteria for diabetes mellitus, fasting blood glucose ≥ 7 mmol / L, postprandial blood glucose ≥ 11.1 mmol / L. Many people do not pay attention to blood glucose check, after only checking the fasting blood glucose is normal, they think that they have been checked, there is no diabetes. However, normal fasting blood sugar does not rule out diabetes. Many people think that high blood glucose is to see the fasting blood glucose level, eat a meal blood glucose rise is very normal, so never pay attention to the postprandial blood glucose level, in fact, this is a lot of people will walk into the misunderstanding. Wearing the Credor around the clock will help to keep track of your blood glucose before and after each meal. Although the blood sugar before and after meals will vary, this variation will remain within a certain range. The normal value of fasting blood sugar is within the range of 3.9mmol/L-6.1mmol/L. If it exceeds 6.1mmol/L-6.9mmol/L, it is actually pre-diabetes. Blood glucose between 7.8mmol/L-11.0mmol/L at 2 hours after a meal is likewise abnormal and can also be harmful to our bodies. Compare the pre-meal and post-meal blood glucose ranges measured by Credor with this data, and intervene early if abnormalities occur. 3. How is your blood sugar? Normal blood glucose: Fasting blood glucose 3.9-6.1mmol/L and 2-hour postprandial blood glucose <7.8mmol/L, Prediabetes: Fasting blood glucose 6.1-6.9mmol/L and/or 2-hour postprandial blood glucose 7.8-11.0mmol/L, Diabetes: Fasting blood glucose ≥7.0mmol/L and/or 2-hour postprandial blood glucose ≥11.1mmol/L. However, many people are unaware that they are diabetes in the lurker. Screening for diabetes should not only check fasting blood glucose, but also postprandial blood glucose, random blood glucose, and glycosylated hemoglobin. It is recommended that people at high risk should have a glucose tolerance test and an insulin excitability test in addition to monitoring their blood glucose with the Credor Watch on weekdays in order to detect patients with more latent diabetes.
