- Case and Crystals
- The Omega Speedmaster Professional reference 3572.50 utilizes a stainless steel case maintaining the established proportions seen in professional models dating back to the mid-1960s. The exterior is defined by a fixed black tachymeter bezel surrounding the dial. The watch is distinguished by its 'Hesalite Sandwich' construction, which combines a traditional hesalite crystal on the front with a sapphire crystal case back. This specific combination allows for the visual warmth of the hesalite material while providing an unobstructed view of the movement through the exhibition back.
- Dial and Movement
- The watch features a matte black dial equipped with tritium-based luminous material on the indices and hands. This material is noted for its potential to develop patina over time. The movement is the Omega caliber 1863, which is described as a direct evolution of the caliber 861 introduced in the late 1960s. The movement serves as the mechanical core for this chronograph, which is operated via standard pushers on the side of the case.
