How can an automatic watch winder enhance the mechanical life of my automatic watch?
In addition to reducing wear and tear of the crown system as mentioned above, a properly designed watch winder can help distribute the lubricating oil inside the watch evenly most of the times. When a watch winds down and stops, the lubricating oil inside the watch will tend to settle and clot, and lose certain extent of its viscosity over an extended period of time. As such, the chance of certain moving parts not being properly lubricated when the watch runs again is much greater. Resulting in increase friction and pressure caused to certain moving parts inside the watch. The consequence would be that the mechanical life of the watch could be shortened and the performance of the watch being hampered. This explain why certain watches, left in a watch retail store for too long a time without winding, seems to perform not in its pristine condition even if it is a “brand new” watch.
