*Unpolished* 1970 Omega Speedmaster Professional MARK II (Ref. 145.014) "Cal. 861"
With the immense success Omega saw from the Speedmaster Professional series, especially after its iconic trip to the moon, they decided the expand the Speedmaster model with the ever-evolving Mark series of chronographs. The Mark II debuted in 1969 with a bold, sunburst-finished tonneau-style case. The Mark III was introduced in 1971 and was the first Speedmaster to employ an automatic winding movement using the Lemania cal. 1340. The Mark IV was introduced in 1973 and melded the Mark II case style with the same Lemania-based movement of the Mark III. After a short hiatus, Omega created the Mark V which featured a very evolved aesthetic that many refer to as 'futuristic'.
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 Caliber 1861 movement. Unlike the Speedmaster Professional, the Omega Speedmaster MARK II has a barrel-shaped case that has polished chamfers and a brushed top and sides, giving it a different look from the standard Speedmaster Professional case worn by NASA Astronauts. The classic timing scale 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 timing scale from scratches or disruption. Unlike modern timepieces with scratch-resistant sapphire crystals, pieces of this era were assembled with mineral glass crystals.

The exceptional case retains extremely crisp factory finishing with sharp edges throughout and is believed to remain unpolished with honest wear throughout. The original mineral glass crystal is in great condition with some minor surface wear, the tachymetre printed on the underside of the glass exhibits some age and wear but is in otherwise very presentable condition. The Omega signed crown and pump pushers are original to the watch. The case back retains the original factory engravings and exhibits some wear from watchmaking tools. The Omega 1162 / 172 Bracelet bracelet retains 24 links that show light stretch and will fit up to an 8 1/4-inch wrist.
The original matte black dial is in virtually flawless condition, showing no damage or notable elements of age. The tritium markers have achieved a charming eggshell patina with no degradation present under UV light inspection. The original tritium hands have aged to a dark grey patina which is common in this era for Speedmaster, under UV light inspection the hands show no degradation.
None. The watch is keeping time, backed by our 1-year warranty on accurate timekeeping.
