If you’re not getting 62-64 hours from a 3861, it’s either not fully wound or needs a service.

Well - here's my feedback.

Saturday afternoon, the watch had run about 50 hours. Since I needed to go out (and wanted to wear the watch), I went ahead and rewound it. I was just happy to see this new watch go that long, for the first time and figured the power reserve was about ready to run out. I did what everybody has repeatedly said - I just wound the watch till it wouldn't go any more. It seems there is a "tiny" spring back at the very end, versus a "dead stop", but I guess that is a "play on words".

Based on the feedback here, it sounds very likely this watch (with the 3861 movement) should make it 60 plus hours. So that is great news! And if not rewound, that should take it into late Monday night or early Tuesday morning since I fully wound the watch Saturday mid-afternoon. I will let the watch completely stop the next time before I wind it again. I want to see if my new 3861 will make it 60-62 hours as others have posted here (although I am happy with 50 hours).

Again, I appreciate everyone's feedback here. It is my first manual watch (ever)! That fact, plus me being told (when I first bought it) to be careful about never over winding, had me being super cautious about it. So that experience, plus 2) taking it back to AD after the watch never made it even 24 hours and 3) being told I had over wound it.....all set me up for being very concerned about my new/expensive purchase.

But, no doubt, most people would have ditched this watch many years ago, if it had to be "babied" all the time! So, I am feeling much better about it now. I will post back after I get results of my full power reserve the first part of the week. I am really liking my new Speedy. Great looking watch, for sure!

All manual wind watches are designed with what is known as a “recoil” click. Every time you release the crown during the winding process, the recoil click allows the ratchet wheel to back up, just a bit. Of course, it does the same thing at the end of wind. At the end of winding, it is conceivable that the tongue on the outer end of the mainspring could become “stressed”, and causing the watch to bank for the first 20 minutes or so after wind has ceased. Result? The watch would gain a LOT of time for those 20 or so minutes. The recoil click prevents that from happening. Completely normal.

I once replaced a crown on a Speedmaster for a friend. After he got it back, he noticed that recoil. I told him it was normal. He told me that it hadn’t done that recoil until after I replaced the crown. He got put in his place, summarily!

My daily routine is to wind @ 30 turns the 3861 each morning. Ten seconds of enjoyment every day!

Newbies read this message board. Are you recommending your winding ritual (30 turns) to some impressionable newbie who want a power reserve of 60-hours on a wind? So many folks expend a lot of advice to newbies, encouraging them to wind their watches fully. We wouldn’t want them to get the wrong idea, would we?

Why count when it's easier to wind until full (should take less winds after 24h if you start with a full PR).

I don't know why something so simple, a daily action that has been done many trillions of times since keyless works were designed around 1847, is now considered difficult or problematic; a worry that the watch will somehow be damaged if wound fully as the manufacturer recommends. I suppose 50+ years of automatic and quartz watches have resulted in loss of basic, common sense knowledge. Curious for sure.

I have exactly the same question when I read concerned inquiries like "will my precious watch will survive rain, dog walking, basically any simple household task including crocheting and gasp - dish washing".

You are not alone. 99% of threads "my Speedmaster stops" here is because people don't wind their watches all the way.
