My Wife's 116234 DJ is +5 or +6
My SubC is +1
My new 116528 Daytona is currently -1 but it's still settling in and I only have 2 weeks of data.

My now sold SS 116520 Daytona was a very solid +10s per month
Don't think I will ever see that sort of accuracy again

Tons of internet sources can be found - this is the one I use.. http://wwp.greenwichmeantime.com/info/current-time/

I use exactly the same source. It's extremely consistent and never seems to fault even on slow internet connections (I ran my phone and pc side by side to check).

Agree

I checked it against my solar 6-band atomic g-shock, and the website is always spot-on.

1-2 seconds a day.

[Darlinboy]

My SubC gets me to meetings on time and I only have to reset it if it runs down while I'm wearing something else.

In other words, keeps perfect time.

[How]

My SubC is currently running at -1.0 seconds (overall) after 74 days.

Call me OCD, but I check it every 24 hours, and keep a record.

which tool you guys used to check the accuracy of your watch ?

I had read an article about twixt application for ios, and used to to check accuracy of my tag heuer monaco and tolex submariner...but don't know whether I can trust the results...

based on its outcome, my monaco gains 0.8s/day, and my submariner is 2.9s/day...

I bought monaco in 2009 as brand new and never serviced...and submariner in few weeks ago as used (but serviced just before I bought it)...so I was expecting better performance from my submariner...

as a second benchmark point, in my company server using atomic watch and I adjusted my submariner and now based on it, it gaines around 30s in 13days which nearly equal to twixt results...

so three questions, is twixt really good tool to calculate accuracy ? if not, what are the other options ? how come non serviced monaco (4 years old) can perform better recently serviced submariner (10 years old) ?

Just picked up a 16750 from a forum member the other day. Could not be happier. Watch running at plus approx. 2 secs plus a half tick fast each day. Timed using US Naval Clock and same laptop to compare.

My first GMT2c would lose around a second a day and I got if adjusted so it gained about the same but unfortunately I had to sell it.
I now have another GMT2c and that loses about the same.As I am a bit ocd about this and I really prefer to set it 'correct' by pulling the crown out rather than waiting xx number of seconds to reset the time.

I tend to have it set fast so it slowly becomes accurate!

[james1787]

The only time mine was checked was when it went for service and I think it was running at +3 at the time. I have no idea what it is running, if anything just a little fast.

[WilliamFoley]

Mine lost around two seconds a day and when i adjusted it did managed to gain one second up till recently..but i accidentally stumbled it upon the floor and from than onwards it seems like it has been losing quite a lot of time each day and the adjustment won't work at all..so any help with this thing will be highly appreciated.

[luvsub]

They run 2-5 seconds fast per day.

[Roley]

I have a broken watch that is 100% accurate twice daily.

[stockjock1975]

My Lange 1 and PP Aquanaut are both dead on to the second. My Submariner is +4 secs/day. Amazing performance from mechanical engineering!

[FireFight]

My GMT2c runs .6 sec a day slow if I take it off at bed time; .6 sec fast if I sleep wearing it, so I think its fair to say it is as close to spot on as you can get with a mechanical watch

[SeaDweller50]

The 3186/7 is a remarkable timekeeper IMO.

[crowncollection]

I don't worry about this much, unless it is radically out, a few second here and there is nothing for a mechanical watch, just wear it and enjoy

[LightOnAHill]

Mine gains one second each week

[drjfc62]

I've never checked. A little fast or slow (if that's what they are) is no big deal to me.

[wrxsti]

i never check, just adjust it to my work clock every so often

[snypa]

+1.5 in the last 24 hours :)

[Datejust2]

My 116334 is +1s/24h

[B2jgc]

I have a 1994 sub and it keeps +2.8 a week. Very impressed !

[Arcoholic]

Stopped checking years ago. I am alway on time for stuff. But now that I saw this thread I just might check again and drive myself nuts for a while:)

[Byrdguy]

My 3 year old Hulk settled in at about -2 sec per week.

[TimeOnMyHands]

My V-series EXPII exceeds my expectations....I set it (at +30sec) when I bought it 40 months ago, and had to roll it back once as it had crept to over 60sec fast...just once in over three years...

[cop414]

My 14060 since taking it off at night has gone from -5.5 seconds per week (leaving it on 24/7) to -3.5 seconds per week (taking it off before bed), much to my delight!
