The watch winder is a device for keeping the automatic watch running when not worn. If you have more than one automatic watch, then a winder may be a good idea for you. One of the biggest benefits of the winder is that it keeps your watch on time and ready to wear at any time. It also allows the date/date function to work properly, so you don't need to reset your watch often when you decide to wear it.<br/> <br/> Product specifications<br/> Shell: piano paint + high density solid wood board<br/> Lining: fiber PU leather<br/> Capacity: 4 winding machine positions, 7 watch storage grids<br/> Motor: Japanese silent motor<br/> Mode: Smart LCD mode<br/> Size: length 34* width 8* height 22 (cm)<br/> Drive: with 3V power cord<br/> Function: Watch for mechanical movement<br/> <br/> (Mode 1) TDP650: 650 laps / 24 hours, that is, 27 laps per hour<br/> (Mode 2) TDP750: 750 laps / 24 hours, that is, 31 laps per hour<br/> (Mode 3) TDP850: 750 laps / 24 hours, that is, 35 laps per hour<br/> (Mode 4) TDP1000: 1000 laps / 24 hours, that is, 41 laps per hour<br/> (Mode 5) TDP1950: 1950 laps / 24 hours, that is, 81 laps per hour<br/> <br/> Packaging includes<br/> 1 x watch winder<br/> 1 x manual<br/> 1 x power cord<br/> <br/> Note: This product only includes watch winder, not including watches.
