Ive just serviced a horn lug 12.15 form 52/53 with an evenly toned dial, a very smart watch  for sale at a keen price, reflecting the initial low cost, notwithstanding the hours put in to bring it around to sensible working order. This one has that odd coppery coloured balance assembly which takes a lot of hairspring  adjustment to get good timekeeping. 

Super dial like the A404 Everest range Deluxe from the '53 period.
