Omega Speedmaster 311 33 42 30 01 001

The Ref. 311.33.42.30.01.001 is also known as the Omega Speedmaster Moonwatch Professional Chronograph 42 mm. Behind the reference number, there is no less watch than the classic Moonwatch with Hesalite glass. Unlike the best-known reference, the Ref. 311.30.42.30.01.005, the Speedmaster 311.33.42.30.01.001 does not have the typical Omega steel strap, but a black leather strap. This gives the versatile Moonwatch a charming Dresswatch attitude.

The details of the reference

Omega reference numbers are among the longest in the industry. Since 2007, the Biel-based manufacturer has been assigning the reference numbers according to Omega's own PIC-14 system, which follows the fixed scheme AAA.BB.CC.DD.EE.FFF. The Omega 311.33.42.30.01.001 stands for:

  • 311: Collection code (311 = Speedmaster)
  • 33: Material of case and strap (33 = steel/leather)
  • 42: diameter (= 42 millimetres)
  • 30: Calibre and complications (3 = mechanical chronograph, 0 = no further complications)
  • 01: Colour of the dial and if applicable stone setting (= black)
  • 001: Model-specific code

The Perfect Watch for a Room and Tailor-Made Suit

The Omega Speedmaster is one of the most versatile wristwatches available. It is therefore not surprising that the Moonwatch is known among enthusiasts as the "strap queen". While the watch on the steel strap is a sporty all-rounder, NASA developed the so-called Velcro Strap for the legendary Apollo missions, which could be worn comfortably around the spacesuit on space missions using a Velcro fastener.

On the leather strap, as on the Ref. 311.33.42.30.01.001, the Moonwatch takes on the character of a Dress watch. The watch, therefore, cuts an excellent figure even on formal occasions. Another charming detail of the 311.33.42.30.01.001 is the Omega pin buckle mounted on the leather strap.
