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 ref. 145.012 Speedmaster Professional possesses a very rare bezel variant sought-after by every Speedmaster enthusiast out there, the "decimal track bezel", which is much different both functionally and aesthetically than the standard tachymetre bezel. 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.
