How Accurate is Your 3861?

I purchased my first luxury watch over the summer: a Sapphire Sandwich 3861 Speedy. As a long-time quartz wearer (a Citizen Cal 8700 which I LOVE), I had to adjust to the fact that - unlike my outgoing $250 watch - it required a minor adjustment every two to four weeks to stay within a minute of my phone's clock but that was well worth the experience of owning such an amazing timepiece. I calculated the average accuracy with daily use/winding to be roughly +4-5 seconds per day.

After a few months of owning the Sapphire Speedy, the nagging feeling that I should have gone Hesalite took over and I ended up buying the Hesalite 3861 and listing the sapphire model for private sale. I was very happy with my decision, especially considering the fact that the new watch was noticeably more accurate. I'm getting about +1.5-2 seconds per day with the new one. This means I can go at least twice as long now before I have to adjust the time!

My question for you: What accuracy are you getting with your 3861 Speedmasters with daily use? Do any of you have one that's averaging +0 (seems possible if accuracy is a normal distribution)? Also, does this come down to the Omega watchmaker spending a bit longer to get a better result or did I just win the brass-lottery with the second watch?

(Also also, do any of you notice that your solid-back Speedys tick noticeably louder than the display-back models?)

Nice! Interesting to see that yours is off by as much as 3 s/d but still manages to average 0 s/d over time. Was it this good since you first got it?

Average 1.5 to 2sec a day since I got it in May, I'm seriously impressed. Hesalite version as well.

+2 sec consistently

Agree. Especially with chronos, for whatever reason. And I have too many vintage watches to worry about leading-edge accuracy, including a few that can sometimes be on a wholly different day by the end of a week.

I did borrow my brother's 3861 sapphire and it was very accurate for the month or so I had it -- around +3spd, or slightly less accurate than the 1861 in my FOIS. So it goes, but I enjoyed the watch -- it's an impressive movement and package overall.
