Unconsciously, the Apple Watch has been released for four years. As early as April 24, 2015, Apple officially released the first Apple Watch in nine countries. Apple said at the time that the Apple Watch is a truly personal device and a new generation of innovations in the Apple ecosystem, offering a whole new way of communicating from the wrist.

This year, Apple's smart watch product line has ushered in the fourth generation, Apple Watch Series 4. Looking back over the past year, Apple has been insisting on upgrading and upgrading Apple Watch to provide more health and fitness features, better waterproof performance, better, larger display, and more independent use.

Like most Apple products, rumors about Apple's wearable devices began to heat up a few years before the official release of Apple Watch. For example, in 2013, Apple applied for a trademark for “iWatch,” but the device was eventually named Apple Watch. The official naming of Apple products is usually relatively clear at the last minute. For example, before the iPad was released, Apple did the same thing and applied for the "iSlate" trademark protection, but also secretly applied for trademark rights for the official name of "iPad". Perhaps this is a strategy that is difficult to cover.

Apple Watch debuted at a press conference in September 2014. Although Apple said it will be listed in early 2015, it was not until another press conference in March 2015 that the wearable device was officially confirmed. The date is April 24th and the pre-order is April 10th. The price of the original Apple Watch is 2,588 yuan, and the Apple Watch Edition series made of 18K rose gold or gold is priced from 74,800 yuan and topped up to 12,680 yuan. The listing includes Australia, Canada, China, France, Germany and Hong Kong. , Japan, the United Kingdom and the United States.

Apple's Apple Watch also has a number of co-branded collections along the way, including the Apple Watch Herm è s series (the most common version starts at 8688 yuan) as a fashion accessory and Herm è s. There are also Apple Watch Nike series that encourage users to focus their smartwatches on fitness (starting at $2888). Apple has also halted production of certain versions, most notably the Apple Watch Edition version, which originally competed mainly with traditional expensive luxury watches.

To be honest, with the discontinuation of the Apple Watch Edition version, not only the average price of Apple Watch has dropped, but Apple has also defined the key target market for Apple Watch.

However, the Apple Watch was officially launched in 2015 to the current Apple Watch Series 4. During this time, although the device has improved a lot, there are always some unresolved issues that plague users. First of all, there is no question of battery life. According to reports, when Apple first developed the Apple Watch, the internal setting should be at least 4 to 5 days. However, this has never been achieved. Even the latest Apple Watch Series 4, in most cases, needs to be recharged every day. Only some light users can support it for about two days.

In any case, Apple's Apple Watch has grown to become the global leader in smart watches. According to data released by market research firm Strategy Analytics in February, in the fourth quarter of 2018, Apple Watch accounted for half of the global smart watch market, reaching 51%. Of course, this figure has fallen slightly, down from 67% in the same period in 2017, due to the strength of competitors such as Samsung and Fitbit.

Yet, Apple Watch is still the brightest leader in the smartphone market. In a conference call following Apple's results for the first quarter of fiscal 2019, Apple CEO Tim Cook said Apple's wearable device revenues, including products such as the Apple Watch and AirPods, were "close to the size of Fortune 200 companies."

There are rumors that this year's next-generation Apple Watch, the fifth-generation Apple Watch Series 5, which may be released in September 2019, will feature a new ceramic case design. By next year, Apple will add more new features to Apple Watch, including an integrated sleep tracking app that encourages users to wear Apple Watch while sleeping to monitor sleep quality and other metrics.

It is said that Apple's sleep tracking function developed for Apple Watch has been tested in the company's internal staff. If the project proves to be viable, it will appear on the sixth generation Apple Watch Series 6, and will also be equipped with low Power mode, so as not to affect the battery life.

As early as June last year, there were rumors that Apple plans to cancel any pushable buttons or buttons on the Apple Watch smartwatch. Instead, it will be the integration of solid-state buttons, and these solid-state buttons are provided by Taptic Engine technology. The tactile feedback simulates the effects of real physical buttons, which not only support touch and swipe gestures, but also built-in capacitive components for advanced health monitoring.

According to the source, the future Apple Watch with solid-state button solution will improve the hardware life and eliminate the seamless appearance of the physical button opening, which will help to provide better waterproof performance. At the same time, because it is a solid-state button, the controller is much smaller than the traditional physical button, and can further release more valuable internal space, which is also conducive to plugging a larger capacity battery to improve battery life.

Of course, Apple's main focus is still a new advanced health monitoring function. Therefore, there are rumors that Apple Watch will bring new features such as blood glucose monitoring in the future, and its strap accessories will also be improved, adding more sensors for health monitoring. There are also rumors that Apple's long-established microLED screen will be the first to appear on Apple Watch, but this technology may take several years to enter the consumer market.

Finally, everyone said that the Apple Watch has been on the market for four years. Are you a user of Apple Watch now? Which generation are you using?
