New 3861 runs in the negative

Whenever I get a new watch, will always do the full wind test in the 6 different positions to get the baseline. More for my curiosity and to see if it needs an immediate service (used) or if it's out of spec from the factory (new)

Have a few where the dial up position run fast by a couple of seconds, others run slow. Will either put them in one of the positions which counteracts it or normally will pull the crown and manually set the time when winding it.

The charm about mechanical watches is each has it's own personality and character. No two are the same.

- 0,5 I would never time my re-entry with that thing!

When I service a watch I list the positions fast to slow in the service documentation, so the owner doesn't have to do this testing, but that's just me. Most people appreciate having that.

Its a bit sad that the Master Chronometer page doesn't show per-position, though it does show the difference between the highest and lowest as well as shows how it did.

Interesting to see that the difference between 'fastest' and 'slowest' is 12 s/day! SO if you had your watch in the 'wrong' position, it could be quite a bit slow, as long as there was a position that was equally faster.

That said, I presume there is a min/max each position can show, but it isn't listed on that page of course( which again, I wish they listed the 6 positions...).

This is the one from a card I had handy, my heritage 300.

The internal specifications that Omega uses ensure that the watch meets the METAS requirements. Those constraints are the average rate and the Delta - that's it.

I found out whatsup. It’s the power reserve. When fully wound, it goes + 0.5 second in the first few hours, then after 12 hours, it runs slow by a second in following 12 hours, so a net of -0.5 seconds loss per 24 hours. I discovered that by fully winding it every 12 hours, and now i am getting a second faster per day. Compared to full wind one time per say with -0.5 second.
What do you think?

See my chart above, that is consistent with the Master Chronometer checks, full wind-to-33% wind is allowed to have up to 8s/day deviation. The one on my Heritage 300 is 1.1s/day, so that is roughly consistent with what you're seeing.

That said, the top ~5-10% of 'wind' always runs quite a bit faster, and it settles in after that.

Right. I guess i will regulate the time keeping by alternating winding once a day and winding twice a day so the gains offset the losses.

Variation for the state of wind is completely normal. This isn’t some kind of fault, but just how mechanical watches work.

A better plan is to buy so many watches that you change watches every day, so you don't ever mind losing a second or two a day.

Glad you hung in. I think you got the right stuff to be a great OF member.

When I joined I got in a pissing match with a couple long term members. After a bit of back and forth, I used the private/personal message feature to talk one on one and we worked it out. (I think that's a highly overlooked feature.) Ended up the two guys I didn't get along with (in separate threads) have become good friends. I even visited one guy at his home in Zurich, twice. This forum is a great way to interact with people across the world, but it isn't perfect.

Glad it's working out. You got a watch to be envious of.

I already have 3 more watches, but I tend to be monogamous with new watches for several months after purchase.

That works for me. I just purchased another one tonight and picked up two others last month. 😀

I'm up to (I think) 15 in my 'daily wearers' (though 2 are away at service), including 6 (soon to be 7 and you'll NEVER guess the 7th!) speedmasters.

Suffice to say, I rarely wear a watch more than 2-3 days in a row, and 'newbies' at most get a week or two of wrist time before I swap.

Yep. I have too many! ::facepalm1::

I'm down to three watches. This one has hardly left my wrist, even though I consider myself a Speedy guy. This and a 145.022-69 Speedy SWA11 could keep me happy.
