For your consideration we offer something quite special, an Omega Speedmaster Mark V from circa 1984.


Omega introduced the Speedmaster Mark series in 1969 with the Mark II and it lasted till the Mark V (1984).



Satin finished stainless steel case measures 44mm without crown but including the crown guard hump. Bezel diameter is 39mm.



The Speedmaster Mark V was based on a design that Omega already introduced in 1982, a reference 345.0803 Speedmaster that was solely intended for the West-German market. Omega refers to this Speedmaster as the ‘Smooth Line’ Speedmaster collection.

Omega Caliber 1045 Or Lemania 5100


As you might have noticed, the dial lay-out doesn’t look like the standard caliber 861 chronograph lay-out. It is very similar to the Mark III, Mark IV and Mark 4.5 watches. The Mark 4.5 and Mark V watches have a different movement from the Mark III and IV though. The Mark 4.5 and Mark V have the caliber 1045 movement, which is based on the Lemania 5100 movement. A movement of which the production ceased a few years ago (although a brand like Tutima sourced enough of them to deliver Lemania 5100 based watches up till last year). The Mark III and Mark IV (and Speedmaster 125) use its brother, the Lemania 1342 based movement.

The Omega Caliber 1045 was also used in the Speedmaster that is being considered the ‘Holy Grail’ Speedmaster, the reference ST376.0822. The Lemania 5100 is a popular chronograph movement by those who love tool watches. Watches with a military look & feel or at least a watch where functionality dictates instead of design.


We love these watches for their quirkiness and boldness, and the smooth case and bullet pushers give the watch a unique, utilitarian feel. The sub regusters also appear to be turning tropical. (Please see attached pic)
