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.
