1970 OMEGA SPEEDMASTER MARK II 145.014 CALIBRE 861 (Un-Polished)

Vintage Omega Speedmaster MK2

We are pleased to offer this stunning early production 1970 Omega Speedmaster Professional MKII. This specific MK II retains its original unpolished case that is not commonly seen with Omega MK II Speedmaster's of this vintage. This piece is in absolutely stunning condition! 

After the Omega Speedmaster Professional was worn on the Moon in 1969, Omega decided to come up with a watch that fit the design trends of the 1970s, thus the Omega Speedmaster Professional MKII was born. The Speedmaster Mark II came with the same Lemania based movement as the original Speedmaster Professional "Moonwatch", reference 145.022. This watch contains Omega’s original caliber 861 movement and was in production from 1968 and lasted until 1996 when omega introduced the the caliber 1861 movement. Unlike the Speedmaster Professional, the Omega Speedmaster Mark II has a barrel shaped case that has polished changers and a brushed top and sides, giving it a different look from the standard Speedmaster Professional case worn by the NASA Astronauts. The classic Tachymetre that the Speedmaster is known for is also different; it is under the mineral glass crystal and not externally located on the outside of the crystal as an external bezel, in essence protecting the Tacymetre from scratches or disruption. Unlike modern timepieces with a scratch resistant sapphire crystals, pieces of this era were assembled with mineral glass crystals.

This piece is in stunning and fantastic condition that would make it a great addition to a growing collection!
