The parts drawer

How to search it

By part number: type it as it's printed, like 860.1305 or 2159. Part of a number works too. By calibre and part: the calibre from the movement bridge plus a word, like "565 mainspring" or "1012 rotor". By part name alone: "balance staff" brings up every balance staff in the books, with the calibres each one fits.

Why "what it fits" is the useful part

Of the 3,973 parts in the drawer, 2,138 are listed for more than one calibre. That's how the breaker's yard works: a part for your 565 might be sitting in a 563 from a plain Seamaster, or a 564 from a Constellation. The red stamps on each envelope are those calibres, and the donor button searches for them. For the parts people hunt on one calibre, see the 565, 861 and 865 parts lists.

Omega stopped supplying parts to independent sellers at the end of 2015, so most vintage parts now come from used stock and donor movements. Measure before you buy, especially stems and anything that depends on the case. If the drawer is wrong about something, email id@watchbreaker.com and I'll check it against the catalogue page.
