Omega Speedmaster Professional Ref 3570.50

About This Watch:

The Omega Speedmaster Professional Moonwatch Ref 3575.50.00 was one of the longest-running references to be produced in the Speedmaster line.  Original production began in 1996 and ran until 2014 when it was replaced by the Reference 311.30.42.30.01.005.  When it was introduced, it was the closest in scale and design to the timepieces worn by the Apollo 11 astronauts, with the exceptions being the use of Luminova over tritium and the updated Caliber 1861 movement.  

The History:  The Speedmaster was introduced in 1957 as a sport and racing chronograph, complementing Omega’s position as the official timekeeper for the Olympic Games.  Its iconic place in history stems from its utilization by NASA for the Gemini Titan III crews, and eventually by the astronauts on the Apollo 11 mission, which made it the first watch to be worn on the moon.  

The Watch:  The Omega Speedmaster Professional Moonwatch Ref 3570.50.00 features a 42mm stainless steel case with a hesalite crystal.  The black dial features a small seconds sub-dial, 30-minute recorder, and 12-hour recorder along with a central chronograph hand.  The black fixed bezel features a tachymeter scale, and the solid case back features the “Flight Qualified By NASA For All Manned Space Missions” and "The First Watch Worn On The Moon" engravings as well as the Seahorse logo.  Powered by the manual wind Caliber 1861 movement, the 3570.50.00 has a 48-hour power reserve and is water resistant to 50 meters.

The Details:  This Omega Speedmaster Professional Moonwatch Ref 3570.50.00 is in good condition, with some wear on the case and bracelet that is visible in the photographs and consistent with a timepiece of this age. This timepiece has the original Hesalite crystal with Omega logo etching.  Included with this watch is the Omega stainless steel 1171/1 bracelet with 633 end links.
