·This 65-70 year old Omega calibre 351 bumper automatic is not rated as a chronometer, but it is 12 seconds fast in 8 days.
How accurate is your Omega?

My experience? Like a superlative chronometer 😁

·Six seconds fast in two weeks! If I hadn’t seen it, I wouldn’t believe it. A 65 year old bumper Omega shouldn’t be this accurate. It has dropped back about 6 seconds in the past week.

·My 3861 speedy is very consistently +1.5/day. I have a 1970s Geneve that, after service, is about +2-3/day. Not bad for a 50 year old watch!

·My 3330 Speedy is less than a second gaining per day in the last 3.5 months!

·Picked up my Planet Ocean on June 11 this year (2022)
. Spent 23 years in broadcasting to the second. So I am very time sensitive (or OCD!). Literately charted it for the first three months and then stopped. Wear it from when I get up in the morning to when I go to bed in the evening, about 16 hours a day. + or - 1 second each day. The other weird thing about this watch, or me, is that I have yet to scratch it. My prior Seamaster from 2018 was scratched within two weeks of getting it.

·Over the week since I bought it, my 3520.50 triple date speedy has lost a total of 15 seconds, which I was/am pleased wth.
However, when I compare it to my 1952 2852 constellation, which typically gains about 20 seconds a week, and comparing to some of the accuracies given here, I do wonder!

·At 10:10:55, MST today, this is a picture of my “survivor” Omega calibre 351, bumper automatic that is close to 70 years old. In the picture, it is approximately 1.5 seconds slow to my one iPad, and has neither stopped nor been re-set since about December 8, (or thereabouts, I don’t remember). At one point ten days ago or so, it was 12 seconds fast. I plan on wearing it for a lengthy period to see how long it can keep this up!

·About a month ago, I bought an AT 220.10.41.21.03.001. (I'll call it blue face). From the start, it was running fast about 5spd.
A couple of weeks later, I bought an AT 220.12.41.21.06.001 (grey face). It also seemed about 5spd fast after 2 days of owning it.
I also have a 231.10.39.61.02.001 (quartz).
I have not let either of the automatics unwind to a stop since purchase.
A little over a week ago, I set them all precisely according to the online atomic clock (of course, there's nothing scientific in the way I went about it).
As I'm typing this:
blue face is running 3 seconds slow
grey face is running 7 seconds fast
quarts is less that 1 second fast.
I'm curious of they just "settle in" with time.

·Please clarify. You have two mechanical watches, one quartz watch, and access to an atomic clock. All three watches vary to atomic time. Will all three watches “settle in” to atomic time? In a word, NO!

Lol, that's not what I meant. I know it's impossible that any watch will maintain perfectly accurate time. What I tried to say, is that when I received the watches, both were more or less 5spd fast (and I understand that looking at the seconds hand is a very imprecise way to measure this). Now, one automatic has slowed down to about 7 seconds per week, and the other to minus 3 seconds per week. Since I haven't owned them for very long, my rhetorical question is whether they will just "settle in" to their own constant rhythm.

As my father used to say - "do what I mean, not what I say."
I hope we can agree that absent malfunctions, watches keep time with a high degree of accuracy ("constant" time).

·My new game after getting my watch back from servicing with a time graphed -2.8spd average is to see how many days it takes of keeping it overnight in various positions and wearing it throughout the day to get it synced with my computer clock. I was at about 40 seconds fast last week Thursday and have gotten it to about 20 seconds fast today.

·Over the past 16 days, my Seamaster Pro 2551.80 with Calibre 1120 has gained 23 seconds, which equates to an average daily rate of just under +1.5 secs a day. Very happy with it. Worn during the daytime and resting dial up overnight.

·After two weeks my CK 859 is running just 1 second fast overall. It gains just less than a second during the day but then resting overnight dial face up it is back to zero in the morning and another day starts. I’m genuinely impressed with this beauty.

·Update on the accuracy of my Seamaster 300 Heritage (8912 movement). It is running approximately* 55 seconds fast after being set 72 days ago. Which means it is accurate to within 0.7638 seconds per day. When sleeping it rests crown up.
*Depends on how quickly I was able to push in the crown and how quickly the watch started when I originally set it.

·I have been wearing my SMP Diver (8800) for 12 days straight now (take it off only during bed time and rest it in a dial up position) and it has gained only 4.1 seconds during the whole time (Average +0.3 second per day)
Never used an app to measure the accuracy of my older watches so i don't know if this is good or extraordinarily good!
Anyone else have a METAS (or not) movement to compare their accuracy ?
Just bought a green Seamaster and it gains about 0.5 seconds per day and I am totally in awe about the accuracy.
The Rolex submariner I owed would gain 2 seconds everyday.
Omega have smashed this movement right out of the park. So well done to those Omega engineers.

·Bought my Seamaster 300 Heritage, 8400 movement about 3-4 years ago, wore it about 16 hours daily for approx nine months. It gained less than twenty seconds during this period. OK probably some gains and losses but still remarkable.
