How many winds on a Speedmaster 3861?
I just purchased an Omega Speedmaster 3861 and would like to know how many "winds" it takes before its fully wound... I stopped after about 70 as it didn't seem to be close to a stop and I did not want to overwind it right out of the box. It winds much easier than my 1861 Speedy and I wonder if they changed the winding ratio to require more winds than usual for a full wind. With most manual watches in my experience it's usually about one wind for each hour of reserve. The manual says "wind it until it stops" which obviously makes sense, but it seems this watch requires more winds than normal. If someone who owns this watch can give me an idea of how many, it would be most appreciated!
I’m a retired Air Force fighter pilot and have been a watch lover for 55 years. My first “good watch” was an Omega Speedmaster MKII I bought with my college tuition money and then took out a loan to g...
Not sure what my model is. I bought it about 10 years ago. It has a stop.
Mine seems to run for about an hour for each wind; so about 24 -25 winds per day. By that reckoning, it’s about 50 winds empty to full, give or take
There’s definitely hard-stop at full wind, so if you’re not hitting that there’s definitely something wrong
1863 caliber has a stop around 90 of my turns from no power. Everyone turns slightly different I would think.
I texted with "Omega USA" customer support and they told me "37 winds". I seriously doubt that is the right number. Still looking for comment from someone who owns the 3861. I may have to "sneak up on it" by winding 37 from dead and then timing the run time. Adjust from there. Had this problem with a Seagull ST-19 and determined full wind was actually about 60-65.
I don't recall how many winds it takes for my 3861 Speedy but I'm pretty sure it's only about 50 or so, and when you reach the max, you should feel resistance. I'd check for you, but I have the watch in for servicing since the stop mechanism had stopped working, so the watch kept winding continuously.

Well, that is curious as mine did not hit at stop at 70... Makes me worry mine is not right out of the box.

I'd suggest taking it to the AD and have them check it out.
When the watch is fully wound, you should feel some reasonably substantial resistance, which is what mine had previously done since I had purchased it in May2021. A few months ago, when I went to wind the watch, I noticed that it kept winding and winding, well beyond the normal stop point. I ended up counting, and it was still showing no resistance after 80+ turns, so I knew something was wrong with it. I have other manual wound mechanical watches, and am very capable of feeling the resistance once a watch has been fully wound, so I know that I hadn't simply forced past that point of resistance. I continued wearing the watch anyway, since it was still working, but I noticed that it also wasn't keeping time as well as it had initially done, so I decided to send it in for servicing.
Best of luck with it. I'd be interested in hearing the outcome.
I'd say about 40 full turns to a stop.. So that seems odd.
My vintage speedy (321) takes about 30 turns to the stop.
Hi lucky for you my 3861 is empty so I give it full wind now to compare. 53 turns and after 40 turns you start feeling slight resistance increasing towards full wind. Anyhow it will stop when you reach the end so go slower after 40 winds. It also depends how much we turn per wind but now you have some reference
First of all, congratulations, a beautiful watch. I’d suggest one wind per hour, 24 winds every morning, with a couple for luck.

Thank you! This gives me a data point I can go from
OK. I finally got the opportunity (and nerve...) to fully wind my Speedy 3861 from "dead to the stop". 91 "half-winds" (back and forth) to a firm, but definite stop. The winding action is exceptional. Clicky, but very smooth and progressive with noticeable, but progressive increases in tension from about 65 winds to stop. The winding is so much nicer than the 1861 sapphire sandwich I owned previously. I don't know if Omega has made any changes in the mainspring from the launch in 2021, but it takes a few winds to fully wind mine. Now I am going to relax and enjoy this lovely watch.
