- Bracelet and Provenance
- The watch is presented with its original Omega bracelet, specifically identified as the 633/1171 reference. The source notes that the bracelet includes full links, making it suitable for larger wrist sizes. The bracelet is constructed of stainless steel links to match the watch case. The source classifies this specific reference as part of the post-moon landing era of Speedmaster models.
- Dial and Case Construction
- The watch is housed in a stainless steel case measuring 42 mm in diameter, excluding the crown. It features a fixed black bezel with an etched tachymeter scale, which exhibits minor normal signs of wear. The dial is black with three subsidiary registers for elapsed time tracking. The hour indices and the hands display signs of age-related patina. The dial is marked with the Omega logo and the name 'Speedmaster Professional'. At the bottom of the dial, the text 'T SWISS MADE T' is visible, indicating the use of tritium luminous material for the markers. The watch is fitted with a crystal, and the stainless steel case transitions into a linked bracelet.
- Movement and Functionality
- The timepiece is powered by the 861 movement, which the source identifies as a Lemania construction. This movement type represents the generation introduced after the earlier variants used in the initial moon-landing-era Speedmasters. The auction description reports that the movement is clean and that all chronograph and timekeeping functions operate as intended. The manual-wind chronograph mechanism is controlled via the crown and pushers located on the side of the case.
