Almost all clocks and alarm clocks use the number 9, in fact, is associated with many strange things.

 

In the Apple Watch app, there are some weird things about the number 9. Why not make it jump to number 10? This question, they never told the user. Today, the team dug to find the answer through the Apple Explained YouTube account and posted it for you to know for the knowledge as described below. :

First. Snooze Alarm function (stop the alarm for a while)

About 50 years ago, the first function called Snooze Alarm was discovered, which was used to pause an alarm clock. It is also made into an analog clock "(a mechanical clock) with this function integrated into the alarm clock.

Continuing with the modern technology generation, they created software utilities also changed their appearance, but they kept the original formula or concept form to avoid creating new ones that differ from the time principle. Even when creating the Apple Watch, the giant invited a watch historian to give a presentation at headquarters to explain to them how to make it by default.

Thus, when Apple develops time-related applications (software on iOS), the company often follows the time found on the mechanical watch or analog Snooze Alarm (machine clock).

Apple intends to set the Snooze Alarm feature on the iPhone to just 9 minutes for the reason that it imitates the original watch.

For technical reasons, because the microphone inside the watch can not work properly when set to 10 minutes to ring once. If you want a smooth process, except before the 10th minute or after the 10th minute. That's why the Snooze Alarm is set at 10, even though the software is now used.

On the other hand, psychological reasons show that 9 minutes of sleep is enough rather than 10 to 11 minutes of sleep, which is a good night's sleep, and waking up again by the alarm clock will make you more drowsy.

All in all, 9 minutes of alarm clock is enough for a little extra sleep, but for this reason there is no scientific evidence yet.

Second. 10:09 on all Apple Watch billboards.

Not different from the above reasons, the setting of 10:09 is according to the previous generation clock standard. In the 1920s, the Hamilton Watch Company identified the 10:09 hour hand as a good place to smile, indicating that their watch was smiling.

Apple recognized this and adopted it more than a century later, and has become one of the best-selling smartwatches of all time.
