About the Omega 2403

The 2500 is the ETA 2892-A2 rebuilt around the co-axial escapement, with 27 jewels, a 48-hour reserve and a beat of 25,200 vph, certified by the COSC. Leaving the date out suits watches drawn from the 1950s, whose dials never had a window, and it gives the crown one position fewer. The 2892 piece explains the base.

In the library it sits under 18 Museum Collection references, the numbered reissues of historical Omegas made in the 2000s, 14 Railmasters, the 39.2 mm and 42.2 mm anti-magnetic models of 2003, 4 De Villes and 2 Constellations. The 37 mm Museum Collection case accounts for 18 references and the 39.2 mm Railmaster for 9. 21 of the 38 are limited editions.

The 8806 is the no-date Master Chronometer movement in the current Railmaster, and the 2627 the 2500 derivative with a power reserve indicator.
