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 early execution 3572.50 features the caliber 863 movements that were produced for Omega until 1996, then changing to the more common rhodium plated cal. 1863 from 1997 on. These early executions are loved by collectors for the visibility of the gorgeous brass 863 movements through the exhibition caseback while retaining the classic hesalite crystal of the moon watch.

This discontinued model is similar to the ‘standard’ Moonwatch model reference 3570.50 but with a sapphire case back. In the current Omega collection, you can still find the Speedmaster Professional with a sapphire case back, but it also has the sapphire front crystal. This reference 3572.50 has the Hesalite crystal on top and the sapphire crystal on the back which makes it more original to the Moon watch offering but with the exhibition case back. The Omega Caliber 1863 movement was the successor of the Caliber 863 movement. The caliber 863 was based on Lemania’s caliber 1873 and was used by Omega till 1996 but the Omega cal. 1863 has a different finish than the 863 dubbing Cal. 1863 movement as the "fancy" movement due to the sapphire exhibition case back
