The Omega Speedmaster Professional is by far one of our most favorite chronographs. The Speedmaster has an incredible history starting with automotive racing moving into flight and eventually to NASA and the U.S. Space Program.  There are many subtle differences within the vintage Omega Speedmaster range of references that make them all slightly unique and different.

The step dial or "Pie Pan" Omega Speedmaster's possess a charm and feel that that the new modern equivalents don't seem to quite have. The ref. 105.012 with the workhorse Cal. 321 movement is clearly built to last. The Speedmaster looks great on the bracelet as well as a handcrafted leather strap. It is one of our favorite chronographs due to its timeless design and functionality. Its versatility to be paired with the most formal and the most casual of wardrobe also makes the Speedmaster a good choice for the first vintage timepiece and or a classic daily driver.

The classic asymmetrical case has been lightly polished in the past, retaining strong dimensions throughout with light signs of honest use. The original "dot over 90" or DON bezel has taken on a nice fade to a dark grey coloration and shows some patina from use. The pump pushers were recently replaced during a routine service, the original pushers will be provided with purchase. The Omega signed crown is an early OEM service replacement.

The watch will come supplied on a 2pc handmade leather strap.


The beautiful matte black "pie pan" dial with applied logo is in fantastic vintage condition, showing appropriate light aging that is expected for a watch from this era. The tritium lume plots have aged to a charming dark sandy coloration, under U.V. light inspection there is some light degradation present throughout which is common from Speedmaster dials of this era. The original hands have been professionally restored with era-correct tritium to match the dial. 


None. The watch was recently serviced and is keeping time perfectly, backed by a 1-year warranty on accurate timekeeping.
