Description

Case: The 40mm straight lug case is excellent, showing some light wear from use. The black bezel is also in excellent condition, showing light to average wear from use. Dial: The matte black dial is excellent, showing some light wear for its age. The lume has aged to a dark sage hue, and the hands match perfectly. Bracelet: The 25-link Speedmaster flex-link bracelet is excellent, showing light to average stretch for its age. Accessories: None. Notes: Due to the preservation of the original pushers and crown, this watch cannot be guaranteed water-resistant.

📖 About This Reference

The Speedmaster reference 105.003 is notable for its straight-lug case design, a characteristic that distinguishes it from later Speedmaster iterations which adopted twisted lugs. This reference is often recognized by collectors as the last Speedmaster to feature this specific case architecture before the introduction of crown guards and a different lug profile. It represents a transitional period in the Speedmaster's design evolution, maintaining a direct lineage to earlier models while incorporating subtle refinements. This reference houses the Omega Caliber 321, a column-wheel chronograph movement, known for its robust construction and serviceability. The stainless steel case measures 39 mm in diameter, presenting a balanced proportion on the wrist. It is fitted with a Hesalite crystal, a material chosen for its shatter-resistant properties. The watch offers a water resistance of 50 meters and a power reserve of 48 hours, suitable for daily wear. For collectors, the 105.003 holds significance as a pure expression of the Speedmaster's early design principles. Its straight-lug case and Caliber 321 movement are highly sought after, appealing to those who appreciate the model's historical progression. Variants primarily concern dial and hand configurations, though the core specifications remain consistent across its production run, solidifying its place as a key reference within the Speedmaster catalog.
