Thank you Sir. That probably qualifies for the fastest ever forum reply I received

What you say ties in exactly with what we know, it was received as a gift "in the late 60s" and we think the glass and crown (I said bezel, I'm really a watch novice) was certainly replaced. Interesting that the chrono hand may have also, looks like it suffered quite an injury.

I will contact chronodeco (Craig) to see what he can do for me. Thanks once again Roffensian.

I might have to disagree on this one. Too many things that don't add up. The back looks like a reproduction to me and the case looks like an earlier model than the serial number, neither of which coincide with a Breitling from 1968. I just spent 30 minutes Googling ref 1155 and couldn't find another picture anywhere. Nothing in Richter's book either. The flat pushers are really the tip off as I think they weren't used in round cases in 1968 and I think the Cadette name wasn't used that late. Might be wrong but I'd be surprised.

To be honest I missed the caseback - started writing without pictures and then only checked the dial when the pictures were posted.

I found this online for an 1155 (scroll down) - http://www.steinbreder.de/index.cfm?fuseaction=Angebote. Don't particularly like the dial on that, but I'm OK with the case and pusher style for it which is consistent with this piece.

68 is definitely late for a Cadette, but not sure if it's too late.

Thanks all, absolutely fascinating

It was originally purchased from Watches Of Switzerland, King Street, Manchester, UK. For around £125 (memories may be a bit faded on the exact price). No paperwork or packaging remains though, I wonder if the original retailer might have records of it? Is it possible to contact Breitling directly for any photos of the old models?

Dear Sir,

Unfortunately we hold sales records for 7 years only, so would be unable to trace the watch sale. Due to the age of the watch parts may no longer be available to under take the service of the movement, but if you can bring the watch in to us, we would send it to Breitling UK for them to advise.
Kind regards Karon
