1994 OMEGA Speedmaster Professional (Ref. 3572.50) "Sapphire Case Back"

(Alan Bean With An Omega Speedmaster Professional On Lunar Surface Of The Moon)

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 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

The Ref 3572.50 with the beautiful yet reliable workhorse Cal.1863 movement would be a great option for the decerning gentleman looking for a unique yet functional Omega Speed. 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.

The excellent unpolished thick case is in N.O.S. Condition. The bezel insert is in outstanding condition and retains a deep black matte look and feel. The case back is sapphire giving you a full view of the stunning cal.1863 movement.

The matte dial is in flawless condition. The tritium lume plots have achieved a wonderful creamy patina and show no signs of lume degradation when viewed under UV light.

None. Watch is running at COSC Spec.
