OMEGA 2201

The OMEGA caliber 2201 is a hand-wound mechanical movement based on the ETA 6498-1, the Unitas 6498. OMEGA redesigned the bridges for this base movement. While not an in-house caliber, the 2201 powers the Seamaster Aqua Terra Railmaster collection. This manually wound movement has been used in several Railmaster variants in steel, gold, and two-tone configurations since its introduction.
