1991 OMEGA Speedmaster Automatic (175.0043 )

The Omega Speedmaster 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 Speedmaster Automatic, also known as the "Speedmaster Reduced" for its smaller 39mm case size, debuted in 1991 to much applause. Finally bringing the Speedmaster into the modern age with the Omega Cal. 1155 automatic movement, which also features a date function. This piece would be suited for casual and formal settings alike as it possesses the classic and timeless Omega Speedmaster look while housing an automatic movement!

The lightly polished case in excellent condition, retaining which and symmetrical lugs that show light signs of use. The original stainless steel tachymetre bezel shows honest signs of use. The case retains its original pump pushers and Omega signed crown. The case back has been very lightly polished and the factory Speedmaster medallion remains fully intact, as does the serial.

The matte black dial with grey sub-dials has achieved a lovely vintage aesthetic with a spotted patina that is consistent throughout and no major damage visible. The grey sub-dials share the same spotted patina and otherwise remain clean exhibiting no damage. The tritium lume plots have taken on a lovely golden yellow coloration and show no degradation when inspected under U.V. light. The original tritium hands match the dial nicely and exhibit no degradation under U.V light inspection.
