Searched over years for both - not often seen on the vendor table. But at least the twins found together. Changed the hands of the silver-dial Seamaster, because the Plongee-hands look better - the original are stored. Reference: 166.0251 launched: 1978 regards Horst
The reason I ask is this background looks familiar... I may have purchased this beauty from you on ebay? For if this is the case, I am grateful!
