Question around self winding

Kmmdad57 · May 16, 2025

I just purchased my SMP one week ago today. I have been wearing it for at least 6 hours every day ( sometimes more). When I went to put it on today, I noticed the time was out by 1.5 hours. The second hand was moving, but some how it lost 1.5 hours in one day. It was perfect the day before. I than reset the time and winded it. I don't know yet happened, but I guess it ran out of power and when I picked it up it restart the second hand again. Just my guess.
My question if I am wearing my watch daily, with normal arm movement, should it not need rewinding?

I have several automatics and they don't need hand winding if worn. But the trouble is how to define what is "worn enough". My dad does pure office work, sits the whole day in front of a computer and then takes the car home - his automatic watch does not get wound enough and shows the same what you experienced. I move more throughout the day, wearing the watch morning-night and never had this issue.

This. Wearing for six hours of sitting behind a desk will likely not be sufficient (unless you are a hand waver when you talk!), so you might want to give it a full wind every so often, or invest in watch winder for the hours when you aren’t wearing it.

Happened to me as well when I was in bed sick. Why not wear it all the time? It brightens your day, looking at a beautiful Seamaster.

I will test it now and see if it keeps power. I have a 2009 Rolex GMT. It only has 48 hours of power and I don't remember that happening with it. How many winds gives it a full charge? I think I counted 60.

If this watch is new, take it back. If used find an Omega watchmaker. IMO there is something amiss with the self wind. I have many self wind watches and none behave as yours does.

I have a couple of Triple Dates and have noticed they needs at least 8 hrs of wrist movement to keep the correct time too, it takes a lot of motion to keep them fully wound I've found.

Okay, I'm learning...
1. I was unaware an auto-mech should to be manually wound before wearing each morning. I had just assumed if it was running, it would stay running.
2. I did the "table test" and it stopped after 51 hours (51 h 21 m).
Thanks for the help and device, Don

If you read the thread again, no one has said it has to be wound every morning. Again, if the watch has stopped, you should fully wind it in the morning, wear it during the day, and it should run overnight. Then the next morning you just need to strap it on and wear it - it should go like this...

How much do you move around when wearing the watch? As noted above, working a desk job may limit the amount of self-winding that occurs.
