The following article explains how the moon phase display works and what the mechanism can do. Would you like to know when the next full moon is and how to set the moon phase display on your watch correctly? No problem, these questions will also be clarified.
Moon Phase Display With Quartz Drive
Watchmaker and AHCI member Paul Gerber have developed a moon phase display with a quartz drive. The EPR 52 micro moon phase developed by him is integrated into the watch strap and connects the mechanical moon phase display and the electromagnetic drive. Because without a connection to the “mother watch,” the moon phase display needs its time source or purpose.
The micro-moon phase has a running time of around three years, which roughly corresponds to the life of a customarily used leather bracelet. This means that the tape and battery can be replaced in one go. The watchmaker also takes care of correcting the moon phase display, which is accurate to about two and a half years.
How Do You Set The Moon Phase Display On A Watch?
The watch’s moon phase display is set either via its pusher or the crown. The respective procedure for establishing the moon phase display also differs. The methods can also vary with the individual watch manufacturers.
Setting The Moon Phase Display With A Separate Pusher
Press the button until the full moon appears in the collection. Then find out what day was the last full moon. Count the days since the last full moon and press the pusher according to the number. The moon phase display is now set correctly.
Example: You wanted to set the moon phase of your watch like Rolex watches for men (นาฬิกา Rolex ผู้ชาย which is the term in Thai) correctly on September 14, 2017. The last full moon was on September 6, 2017, 8 days ago. This means that you have to press the pusher 8 times until the moon phase display on the watch matches the current phase of the moon.
