Fear that the mainspring may break if you wind the watch until the crown reaches a hard stop means there is no answer to the power reserve of your Speedmaster. Persist in this fear, and you’ll never have the answer to power reserve. Mainsprings break, it’s a fact of life, whether you wind the watch fully, or whether you don’t. I wound my Speedmaster with the calibre 863 movement in it, yesterday. The watch was run down, and it took 60 “twists” of the crown to wind it to a full stop. It has proven to run well over 50 hours from a full wind, with the chronograph functioning all the time. Here are pictures of a broken mainspring that I replaced for a friend, several years ago. This breakage had nothing to do with how he wound the watch!

Ok, it stopped after 21 hours. This time it took 102 turns to the "hard" stop which is interesting. Do these things have a break in period? I wouldn't think so after it's been through certification.
24 hours and still going.....
Already sounds like things are better this time around! Don't worry too much about getting the winding wrong, you're FIXING that now, much better condition than staying ignorant. We've all done it someway, somehow.
Welcome to the forum!
30 hours now. So I sent one in for repair and bought another one when I didn't have to. But now I have the set...
Neither of mine last anything even close to 50 hours. My new white one is off at omega because it only lasted 8 hours. The new black one is I bought to wear while it’s gone lasted 15 hours today. None of my automatic omegas last anywhere near the stated reserve either. I’m getting disappointed with the brand at this point. No they were not mistreated or overwound, I literally got the black one yesterday.
