April 1 to the smart watch market began surging --Apple Watch around the corner, $ 20 million project to raise the level of public Pebble Time and Pebble Steel poised for the occupation of these watches are getting ready for the consumer's wrist. However, before the market becomes hot wearable device, there is a watch once in a very long time to dominate people's wrists.
24 years ago, Casio launched the world's first smart watch Casio F-91W, it can be said to be the ancestor of the smart watch, there are still many advantages that can be learned. Today, we say that this watch for legendary.
Casio F-91W and the world's first GSM digital networks are into sight in 1991, although this watch appeared ten years earlier than a smartphone, but in addition can not push information notice outside, rich functionality , called the metamorphosis of life it deserves the title of smart watches.
It is understood that Casio watches are still selling this, though it has never been publicly sold, but presumably it was a very large number, so that the market today are far too smart watches.
All-plastic body is used in F-91W resin material strap and weighs only 22g, it is equipped with a Casio back in 1991 seems very large LCD screen that can display time, date, weather and other information, It also has a clock, the whole point timekeeping and stopwatch functions. Moreover, F-91W also built LED lighting, adequate lighting in every corner of the LCD screen.
This watch uses a classic three-button Casio, all functions are switched page through these three buttons to complete. For example, you need to enter the stopwatch from the main interface screen time, then you first need to press the button on the bottom left of the mode switch, and if you want to set up on the stopwatch mode, you can to the right of the Options button, and finally press the top left of the election set button, which is now a bit like the OK button.
It should be noted that all the above operations are not tips to help you choose the option to make only a simple click on a page switching, seemingly in trouble, but after the fact, or skilled very easy operation. Because you can cycle through, so there is no mistake, fault-tolerant and low rate.
At the time, sports enthusiasts will use the F-91W stopwatch function to act as a timer, because in addition to the timing of data on a single screen, the background will record the total time. In addition, this watch also has a waterproof, rain drops can prevent splashing of daily use, but can not be used in the shower.
Finally, we say that this watch for endurance. Pebble claim to watch up to seven days battery life is the biggest selling point, this Casio only saying "Oh," and, of course, this is only small series of their own ideas, because Casio F-91W under normal use alarm and LED lights can 7 years of continuous work, yes, that unit is the year, this figure now seems, simply can not be copied miracles.
It is worth mentioning that, after a lapse of 24 years, F-91W classic retro design still looks backward, no one would think to bring such a watch is a disgrace. Now it is very worthwhile to learn smart watches manufacturers, want to make their own product design was endorsed by the outside world is not an easy thing to see now on the "dial should be round or square," the topic of debate know.
After 24 years, who will remember April 2015 Smart Watch what you listed?
