What's the reserve ?

As my collection grows, I find myself asking questions, and enjoying learning about these vintage Omegas. I decided to put full manual winds into each of these today., 1950,1960,1970. I'll monitor the reserve power. I did notice each watch seems to have a different number of Crown turns from a stopped position. Has there ever been a standard or is each model different? Thoughts?

Each movement will be different, IMO.

Reserve power would be more consistent compared to crown turns

Am I wrong to think reserve power is how long the watch runs for when not worn and fully wound?

You are correct. I was trying to say watches may have a well-defined reserve power but not so much on the number of crown turns to reach that maximum reserve power. However, I am happy to be corrected.

Thank you. Yes, it's just reserve power I'm interested in. Number of turns will be dictated by gear ratios and mainspring spec. I was just curious if there was a "standard" for reserve, where one can determine general service, or mainspring condition, based on reserve time. I see many people quote the reserve time, and thought there must be a reason.

Yes, you can research the power reserve of a given movement caliber. In your original post, you seemed to be asking about the number of turns.

If you can't find the power reserve of a particular movement, feel free to ask, some members may have collected reference information.

Sorry for the confusion. I'll look for that info, thanks 🙏

If anyone is interested, I decided to put a (relatively) full wind into my 3 vintage watches to test the reserve. Here's what I got.
Movement #
342 = 38hrs. *1950
552 = 42.5 hrs. *1960
565 = 46.25 hrs. *1970

What's the reserve ?
