An old Diver with a new look: Ref.

Ref. refers to a historic vintage diver presented by the Swiss manufacturer Omega in 2014 as a modern re-edition. The Omega Seamaster 300 Master Co-Axial. While the modern Ref. is the spitting image of its historical ancestor from the 1950s, the Seamaster 300 at the time bore the Ref. CK2913, the divers' watch conceals a modern Omega calibre inside.

At CHRONEXT you can obtain the Omega as well as many other references and interesting Omega vintage watches at attractive prices. 100% original: In our in-house master workshop, each model is extensively checked for authenticity and quality and comes with a 24-month CHRONEXT warranty.

All you need to know about the Ref.

The Ref. appears complicated at first sight but follows a logical scheme (AAA.BB.CC.DD.EE.FFF) based on the PIC-14 system used by Omega. Specifically, Ref. has the following meaning:

  • 233: Collection code (233 = Seamaster 300)
  • 30: Material of case and band (30 = steel/steel)
  • 41: Diameter (41 = 41 millimetres)
  • 21: Calibre and complications (2 = Co-Axial calibre, 1 = one complication)
  • 01: Colour of the dial and if applicable stone setting (01 = black)
  • 001: Model-specific code

The best of both worlds

With the Ref., Omega has succeeded in creating an authentic and historically accurate re-edition of the classic Seamaster 300. Except for the Co-Axial lettering and the slightly wider bezel, the Ref. has the exact appearance of its historical counterpart. Omega has also implemented the vintage luminous material excellently. With the Seamaster, the Manufacture has developed a Heritage watch that is true to the original. This watch features full water-resistance, a magnificently luminous substance and a reliable and modern Manufacture calibre, but with all the charm of the 1950s.
