The Breitling Watch Source Forums

Hi,
I am new to Breitling watches and have recently obtained my very first - A B-2 Navitimer.
My question (which will be very simple) what is the small round disc/cap for on the opposite side to the crown?
It a small flush fitting disc at around the 10 o'clock position?

Thank you

It's for access to lubricate the inner rotating bezel.

Thanks for the information, why or what would be the issue for it falling out all the time?
I can see it has a seal around the cap, could it be that the seal has dried out??

Ooh, yes there's an issue there. It shouldn't fall out and should only be accessed during a service or overhaul. Maybe a result of inexperienced intervention. Have you had the watch long? May be due for a service. I have a B-1 and an Airwolf with the same type of cover with no issues so far. It may be difficult to find a seal as Breitling don't sell parts to third parties & I don't know where you'd find one.

It was serviced in October so I may have to send it back?
Is it just reliant on the seal friction to hold it in place??

I don't know, but I'd send it back for rectification. Could have been a re-assembly error, old seal or wrong seal used.
