The Omega Speedmaster Professional ref. 3572.50.00 combines the classic appearance of the Moonwatch with a view of its movement. Its 42 mm case and bracelet are crafted in stainless steel, while the black dial with three subdials and the tachymeter bezel retain the model’s familiar design.

The reference is distinguished by its combination of a domed Hesalite crystal on the front and a sapphire display caseback. The latter reveals the manually wound calibre 1863 chronograph movement with its rhodium finish. This pairing makes the reference an appealing choice for those who appreciate the character of the traditional Hesalite crystal while also enjoying the opportunity to observe the mechanics beneath the dial.
