Omega Speedmaster Moonwatch Professional Ref. 310.30.42.50.01.001 – Full Set

Reference 310.30.42.50.01.001. That string of digits identifies the Omega Speedmaster Moonwatch Professional in its purest, least-compromised form — 42 millimeters of stainless steel paired with a black aluminum bezel carrying the tachymeter scale, a Hesalite crystal over the black dial, and nothing extraneous.

Powering it is Omega's manually wound Co-Axial Master Chronometer Calibre 3861, a movement that has cleared METAS certification requirements. Power reserve sits at roughly 50 hours. The chronograph runs through the classic three-register layout, water resistance is rated to 50 meters, and the whole thing rides on its matching stainless steel bracelet — consistent with the standard Moonwatch Professional spec from top to bottom.

The watch is offered out of Florida as a full set. After the auction closes, it heads to Bennison Watch in West Palm Beach for authentication before any transfer happens. Payment goes directly from buyer to seller once that process wraps up, at which point the buyer arranges either in-person pickup or secure shipping. Tariffs, duties, customs fees, shipping, shipping insurance, handling, transactional fees, and any miscellaneous charges fall to the buyer. A 6% buyer's premium applies, subject to a $300 minimum and a $3,000 cap.
