Fantastic ! This watch was originally issued to the Royal Navy (0552) circa 72 as thats the DOM but possibly issued later. At some point it looks like it was re -issued to the RAF, probably at an MU ( maintenance unit ) and given the a new engraving prefix. The 6BB prefix is RAF issue wristwatch. Prob worth around 2.5 K , to the right person maybe more.
Beautiful watch. Glad you're keeping it :-)
EDIT : how is the strap attached ? These watches have fixed bars ( or should have)
