Smart watch for men
The flyback and retrograde forms of the watch hands are not clockwise. Flyback is the characteristic of the chronograph returning to zero, while retrograde is the "fan shape" of the hands. The fan-shaped retrograde is weird, it automatically returns to zero after the full distance.
The chronograph function watch is commonly known as "three needles and three eyes", and it also has 3 crowns at the same time.
1. Most of the chronographs currently use a double-button type, and the two buttons are usually at 2 and 4 o’clock respectively. The 2 o'clock button controls the "start and stop" function, and the 4 o'clock button controls the "zero" function.
2. The operation method used is usually the process of "starting---stopping---returning to zero" or "starting---stopping---starting---stopping---returning to zero". The stopwatch function must be stopped before pressing the reset button.
3. The single-button stopwatch is relatively simple, and the function of "start-stop-return to zero" is controlled by one button. Please note that every time you press the button, you must wait for the button to reset before you can press it a second time.
Moon Phase Display Moon Phase is actually a lunar calendar, indicating the cycle of the moon's waxing and waning. The sun, moon and stars are the most intuitive celestial bodies, but the phases of the moon are related to latitude.
Design principle: The moon phase function is often placed in a special-shaped semi-circular window, which includes a semi-circular arc and two small circular arcs. This carefully crafted shape, combined with the moon on the moon phase disc, tells us more accurately what the moon looks like at the beginning or end of a cycle.
How it works: The moon phase is based on a 29.5 day cycle to show the state of the moon on the moon phase disc. There are two moons on this moon phase disc, and there are 59 teeth on the edge. After being pushed by the transmission wheel, the moon phase wheel moves forward by one tooth every day. At this time, the change of the moon phase profit and loss can be displayed on the dial in time.
The 59-tooth moon phase wheel comes from the average value of the moon phase profit and loss every 29.5 days. Since the precise rotation period of the moon is 28 days, 12 hours, 44 minutes and 2.9 seconds, the error of the moon phase display is about 33 months. will reach 24 hours. There is usually a moon phase adjustment button on the case, and the moon phase display is relatively independent from functions such as chronograph and perpetual calendar.
