Omega Genève Dynamic has stopped running - advice

I have an Omega Genève Dynamic from 1970-ish that's stopped running. I've seen conflicting info on whether the caliber is 565 or 752. It was serviced about 20 years ago but has spent most of that time in a drawer. I only started wearing it again about a month ago and it kept perfect time. Until yesterday when it stopped. Shaking/swirling the watch doesn't help.

Does it definitely need to be re-serviced or is there a way to restart it? I've read about winding the stem 20-30 times, but the stem doesn't turn unless it's pulled out to set the time.

If it has a date only it’s 565, day date means 752.

Mechanical watches have oil to help run, after time the oil degenerates so there is no other alternative than to disassemble, clean and lubricate then reassemble.

Depending on your location you find a watchsmith who has an Omega parts account nearby. Once properly serviced it should run smoothly for 5-7 years.

Twenty years since last service, yeah it's time.

It's like running your car for 20 years without changing the oil. Imagine that 😁

Get that Omega Static serviced so that it can be a Dynamic once again.

Worn or not 20 years is way past due for a service.

I wasn't sure if the years of non-use counted toward time for servicing. Anyway, I'm taking it in tomorrow. Thanks for all your responses. I posted this on the r/watches sub reddit and got nothing.

The oils that provide lubrication and prevent metal-on-metal wear inside the watch movement dry out with time whether the watch is used or not, so there are actually brand new watches, especially models and brands that nobody really wants that sit in display-cases for years before being eventually bought by some eBay BNIB watch dealer that are actually in need of service before they have ever been worn.

The good news though is if it has hardly been worn in that time, there has been very little actual wear from being run without lubrication and the parts are probably in about as good a condition as they were in after the last service.

I'm in a similar situation, and trying not to start a thread unnecessarily, with an Automatic Geneve Dynamic with date. I volunteer preparing watches for sale that have been donated to our local non-profit Hospice. I have no watchmaking skills, so I clean externally, check timekeeping and market appropriately as functional or not. I had a Seamaster decades ago that I foolishly sold, so this one has stuck a chord. When it came to me, I wound it a few turns and the second hand started sweeping, so I just set the time and wore it for a couple of days, taking it off at night. Each morning it was running, so I just put it back on and it kept time within 10 seconds over two days, indicating it was working, but could do with servicing. Then I left it and it did not respond with continous sweeping of the second hand after a couple of shakes, so I wound it fully and the best it can manage is 5-15 seconds in response to a couple of shakes. Oneother observations I've made with it in its uncooperative mode:
- when I pull the stem out to the first position to adjust the time, the first amount of rotation of the crown in either direction moves the second hand a second or so. When I move the minute hand positively by a few minutes, it starts the mechanism for a few seconds.

Have I been caught out by old oil or is the above indicating something amiss please? It's decades since I owned my Seamaster.

Thank you for supporting our hospice!

I commend you for your volunteer activities.
It certainly sounds like it is in need of service but only way to find out for sure is to take to a reputable watchmaker. One preferably that is Omega qualified. i.e. has spare parts account.
