I am letting go of this awesome, no introduction needed, Speedmaster Professional 3570.50. Serial number of 77XXXXXX puts the birth date at 2005. The piece is running excellently. I do not have a time grapher so I can’t give you numbers but compared to my phone it is keep good time. With no major damage or scratches anywhere, though it does have the usual daily wear you’d expect from a 19 year old watch. The pictures probably won’t show all the super small stuff as I’m not super fancy and only have an iPhone for a camera. All that said I am not the original owner and I don’t have any service paperwork on it so I’d probably keep it dry until you have the seals checked. No box or papers, 15 links total, 5 removable links and 1 removable half link(I don’t know how many they originally come with). $3600 Shipped inside the U.S. Only. NO TRADES. I can accept Zelle as a primary but can also accept Venmo F&F. Omega Specs: Link to Omegas website The OMEGA Speedmaster is one of OMEGA’s most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brand’s adventurous pioneering spirit. This OMEGA Speedmaster Professional “Moonwatch” features a black dial covered by a hesalite crystal and graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. The black bezel, with its tachymetric scale, is mounted on a 42 mm stainless steel case and presented on a matching bracelet. At the heart of this chronograph is OMEGA’s mechanical calibre 1861, the famous manual-winding movement that was worn on the Moon.
