Diver 300 8800 erratic time keeping

cjoedaniel

Mine was was ticking away just fine with known positions to self regulate.. So I had it at +0s.Then 3 months in the tolerances changed in the same positions. I attributed it to the change in ambient temperature as it got warmer. The tolerances were different but at least consistent. Now it is getting cold here again so I am curious to see if it will change back but I'm not holding my breath.
I'm at +8s now after 7 months as my overnight crown up position is only getting me -.3s when it used to be more like - 2s. So harder to self regulate.

change in ambient temperature as it got warmer.

Not likely.

Magnetism! I just demagged my 2254 Seamaster Professional. Some positions were -14. When I was done the positional variance was -1 to +3 with decent amplitude.

Your watchmaker will likely demagnetize for free.

iDevices have STRONG magnets in them. Don't set your watch on your iPad!

15000 gauss strong?

Yea my wife magnetized her Deville and it was 5 minutes fast. But it’s not a metas watch

I also went from a bracelet to nato which can also affect timing because it just wears differently.

If the SMP came to me slow it would be a different story. The sudden change out of the blue is what has me worried. Almost a year of running fast then BOOM, it’s slow.

cjoedaniel

I do remember mine going from perfect to slow at first at that 3 month mark but then it settled a bit and I was able to get back in the + direction.

Also rotating watches is tricky as it's hard to consistently keep track of wrist time/power reserve. I do notice if I'm wearing the SMP less and it's winding down, it does affect my rate.

Did you recently change something in your rotation?

Bimmerman77

No not at all. I wear each watch anywhere from 2 days to a week. I keep them on my orbita winders when not in use. My other watches that don’t get worn much stay in the watch boxes. I’ve tested it at 100% and 50% power, and it’s still slow. My other master chronometer, my AT 8900, has been running flawlessly for almost two years without a hiccup

cjoedaniel

Sounds like you are very diligent about your watches. Hopefully things will slowing shift to the + side in the next few days/weeks. I don't use winders but I can see how having them could help with the power reserve issue. Is the SMP going into the same winder?

Sounds like it's still running within specs, right? What do you think they would do if you sent it in?

Bimmerman77

Yup same winder. My orbita has four winders and each is programmed independently of each other. I have the TPD correct so I’m stumped man. It’s the only piece I have that’s ever done this besides watches that needed a service from years of use.

cjoedaniel

Hmm I guess the only thing I can think of is that it may have taken a slight knock/bump at a particular angle while wearing.. That stuff happens and usually out of your control or goes unnoticed at the time.
I try to be really careful but once in a while mine will get tapped at the edge of a desk or doorway.
Anyway keep us posted on what Omega has to say.

Nor likely! The 8800 is much less susceptible to magnetism than the 1120 as it uses a silicon balance spring. I doubt that is the issue. More likely a knock, or a local lube issue.
