I think the father-in-law has mentioned it to the local auction house (who are selling some war-time medals & other bits shortly) who suggested it might fetch £2- £4K?[/QUOTE said:
Tongue firmly in cheek here - I will give you £4K without you even needing to bother opening the back, heck I will even bully my sister into driving up with the cash.
The bezel alone is probably worth £1K and the bracelet another £1K.
If you do let the local auction house sell it at least make sure they have a good online bidding system and try to promote the auction too, You are too new to actually sell here, but a link to the auction would probably be acceptable.
