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.

This Omega Speedmaster transitional model Ref. 145.012 dates this specific example too late 1968 uses the earlier Caliber 321 movement. The original matte black stepped dial with applied Omega logo has achieved a wonderful patina and the bezel insert has the original dot over 90 (DON) bezel, and pre-moon seahorse case back. This specific example is a very rare last production pre-moon reference. 


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 145.012 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 case is in overall excellent condition showing original factory finishes and sharp lugs that we believe remains in unpolished condition.  The original bezel insert is  "Dot over 90"  (DON) and has achieved a wonderful deep anthracite fade. The "Pre-Moon" Seahorse case back has very minimal wear and is clearly visible. This specific example retains the original Omega 1039 Bracelet with accompanying and original 516 end links and shows very minimal stretch. The crown appears to have been replaced by Omega at some point as it is not a "flat foot" crown more commonly seen with cal. 321 movement Omega Speedmasters


Amazing black matte "step" dial with applied Omega logo.  The tritium markers on the dial have achieved a wonderful creamy yellow patina and remain fully intact with no lume degradation when viewed under U.V. light. The tritium hands have also achieved a wonderful creamy yellow patina and show no lume loss and remain fully intact.


None. The watch was recently serviced and is running at COSC Spec backed by a 1-year warranty on movement.
