Are you the owner of a perpetual calendar from Patek Philippe or the H. Moser & Cie Perpetual 1?

If you are, you’ll know that such watches are designed to not require adjustment until the year 2100. The highly complex movement is able to distinguish the number of days within a month and whether it is currently a leap year so that the display of the day, date and month are correct.

Differing from the annual calendar, which requires an adjustment in February to account for leap years, or the normal calendar watch, which requires adjustment depending on how many days there are in that particular month, perpetual calendars are the ultimate expression time-keeping over very long periods.

One problem though, that you might have encountered is that since your perpetual calendar is only one out of a number of watches in your regular rotation, when the power reserve runs down, or you leave your watch alone for some time, when it comes time to wear it again, you have to wind and set the watch. That is a whole process which can sometimes be quite lengthy and cumbersome.

In order to avoid this, look to the Time Mover – HandWound by BUBEN&ZORWEG.

This is a winder specially developed for handwound watches and is the ultimate accessory for those handwound watches you wear quite often and want to use at a moment’s notice without having to set the time.

A computer controlled mechanism winds the watch grasping the crown while it is in the cradle. Sensors monitor the state of the power reserve, and when you first use it, it goes through a learning process to calculate the number of turns required to reach full power. From there, using this information, it monitors the power of the watch, and winds it on a carefully calculated schedule to maintain between a 60-70% power reserve.

BUBEN&ZORWEG are known for their luxurious watch winders and watch-safes, and this is yet another interesting product that combines luxury and utility for the serious watch-owner who appreciates hand-wound watches as well. Find out more at www.buben-zorweg.com
