Hello. I purchased a "clean, lubed, adjusted and timed" 1950 Longines 22A (automatic) watch from an eBay seller recently. The watch was physically described accurately. As I do with all my older automatics, I gave the crown 20 or so half-turns and strapped it on. After two days, it quit running until I wound it by the crown again. I have a pretty active lifestyle and I've never had an issue with an self-winder not getting enough rotor time to keep the watch wound. Plus, although I couldn't verify the number of hours, the 22A likely has a power reserve of 40-44 hours and that's about how long it ran before kacking.
When I contacted the seller, this was his reply:
Thanks for the email. I am please you like the watch.
The automatic function may not wind the watch enough during the day to keep the watch running night after night. It depends on how active you are.
(If for example, you put the watch on a watch winder, it will run continuous, without stopping.)
What you can do is when you wake in the morning, give it a few winds. This with the movement you do throughout the day should ensure it runs continuous.
I'm no expert so I want to be fair to the seller. Is it reasonable to expect to hand-wind an automatic, as he suggests I do? The watch comes with a 90 day warranty and return privileges for 2 weeks (I'm still within that window of time). Also, if possible, I'd like to keep the watch -- but have it work as I expect it to: no extra winding when being worn, unless my expectations are unreasonable -- so what would you suggest?
(Also, I do have a winder so I could test his assertion about it running continuously.)
Thanks for your opinions.
