Pin diameter: 1.8mm. Sized for contemporary Omega watches with lugs slightly wider than the standard 20mm: Seamaster Diver 300m 42mm, Seamaster Planet Ocean 42mm, certain Constellation Globemaster variants.\u003c\/p\u003e\u003cp\u003eThe 21mm Omega is a transitional geometry between the classic 20mm and the 22mm of heavy sports models. It appears on 42mm models where Omega sought a slightly more pronounced presence on the wrist. Pin 1.8mm — the Omega standard remains unchanged even on this intermediate size. It is the exact specification for the Seamaster 42mm: aftermarket 20mm bars will not fit correctly here.\u003c\/p\u003e\u003cp\u003eThe same spring bars I use on clients’ 21mm Omega watches.
