The Breitling Watch Source Forums

As it's been documented, the standard acceptable accuracy of mechanical wristwatches is as follows:

Worst Case Scenario +/-10 seconds per day 99.988% accuracy
Typical +/-5 seconds per day 99.994% accuracy
Excellent +/-3 seconds per day 99.996% accuracy

On average, are you gaining or losing daily with your Breitling?

Gaining 5 seconds per day on my SA
Gaining 3 seconds per day on my EVO
Gaining 5 seconds per day on my Bentley

I didn't know whether you were including Superquartz here so - my Airwolf gained about 2 secs over a roughly 6 month period, pretty accurate in my opinion

Well I don't agree with your numbers for worst case / typical / excellent when it comes to Breitling. All Breitlings for the last 10 years or so have been COSC certified so worst case should be -4 / +6

Mine are running between 0 and +4 right now.

SSOF +5
Blackbird +4
Lemania Cossie +2
Airwolf -1 combined over last 10 weeks

both mine run fast. but im well within cosc specs

Chronomat 01 LE runs +0.3 a day.
Colt Auto II runs +1 a day.

This might sound dumb..but how are you checking if you gain or loose a few seconds?

My Breitlings are all fast but within COSC, which is exactly how I like a watch to be (if it's not spot on of course). A slow watch is a PITA - and I do have a couple of other autos that fall into that camp.

And then there's my BP of course.......

Remember calling from your cell you will be 1 sec late due to system latency. Therefore always check your time from the same phone line.
