37524

An ETA 2892-A2 base with a 21K gold rotor weight, finished by IWC. Mechanically it is the same movement as the 37521; the two differ only in the height at which the hands sit, so that one base could serve cases of different depth. The 2892 is the thinner of ETA's two workhorse automatics and the one chosen where case height matters.
