Turns per day question: 1968 Oyster Date

[tulgsT]

Would anyone know if it is safe to put a 1968 SS Oyster Date on a watch winder? If so, any idea about the turns per day setting? 500, 650, 800, 950 or 1300? Once the watch stops, there is no way to perform a quick date set which is kind of a pain---the watch needs to be wound full rotations AM/PM until the date is achieved. Thanks in advance for any advice!

Since an Oysterdate is a manual wind, a watch winder would not help matters.

Unless you mean an Oyster Perpetual Date? If so, if it's been properly serviced, and you have it serviced again every few years, then yes, it's okay to have it on a winder. However, a winder could wear the parts of the cal. 1575 movement if it's not serviced relatively frequently, as it's essentially running 24/7. I am not sure which interval is appropriate, but it should be bidirectional. Try it on a low-to-intermediate setting (first wind it 40 times to generate full power to the mainspring), and if it's running fine, that should be okay. I've kept a couple of my cal. 15XX watches on a winder without problems.

Yes it's an Oyster Perpetual Date. Thanks for the info Adam.
