The Breitling Watch Source Forums

Merry xmas guys!

i haven't worn my skyland in about a week or so and decided to were it for christmas yesterday, but when i started the chronograph it was running very... jaggedly, if you get that i mean. I ran the chronograph all night and it seems to be running fine now. So it got me wondering, has anyone got any advice as to how to keep a chronograph at its best? do you run the chronograph wile it is in the winder, do you start it for time to time?....

Cheers in advanced,

Tom

I run my chronos for at least a full 24 hour cycle once a month to keep the oils spread.

The 7750 does have a tendency to be a bit jumpy at the start of a chrono cycle so keep an eye on it - it can be adjusted my the service centre.

cheers roff! ill give it a go

Don't mean to hi-jack the thread, but is this also true of a new chronograph? The jumpy/jagged chronograph seconds-hand that is... I just got a new Avenger and am noticing the same problem, although I haven't let the chrono run for very long (am trying that now to see if this will get it fully lubricated). Is there a normal "break-in" period before it starts running smoothly? Thanks.

It's a design 'feature' of certain movements including the 7750 that your Avenger is based on. If it doesn't improve then take it back and Breitling can have it adjusted. May need to be sent away depending on whether your AD is an authorised service centre.

Thanks for the info. I've let the chrono run for nearly 20 hours now and sadly it has not improved It also seems to have lost nearly 3 minutes of time also during this period. I'm assuming this is not normal operation. I put in a message with my AD. I really hope I don't need to send my new watch in already!

Chrono shouldn't affect the accuracy.

If it's just the chrono that's losing time (not the main watch) then there is more than just the jerky seconds hand - something is slipping somewhere. Definitely take it back to the AD.

I have experienced this with both 7750's and DD module chronos. But it is always consistent with mine... in other words it always does it. It doesn't get better then worse again. I sent the DD module watch back for service and they returned it and said it was within spec and just a characteristic of the movement. I doubt it, but I've learned to live with it for now. Its not too bad, but I see it. I've had much worse cases of this with 7750's. The jittery chrono sweep is apparently caused by some gear lash in the drive train, and should not affect accuracy.

As Roff said, the service center should be able to fix it, hopefully with better success than my non-breitling experience.

If it is losing time, thats a whole other problem that warrants a trip to service.

It's the main watch that has lost time. Hard to explain, but I set the chrono in sequence with the watch seconds hand and those two remain in sync. The main watch minute hand is now about three minutes slow. Does that make sense?

The explanation makes sense, the behaviour makes absolutely no sense.

The only possible way that the minute hand can lose time without the seconds hand losing time is by slipping.

Get it to an AD to get it checked out.

Will do. Bummer.

I have stopped the chrono and reset the time to see if it still loses time when the chrono is not running... Will let you know how that turns out and what the AD says. Thanks for all the responses.
