About Used Omega Watches
Omega has produced precision Swiss watches since 1848, and its sports and professional lines have earned global recognition through associations with NASA moon missions, Olympic timekeeping, and deep-sea exploration. The Speedmaster earned the name Moonwatch after being NASA-qualified in 1965 and worn on the Apollo 11 lunar landing, while the Seamaster Diver 300M and Planet Ocean lines are built around robust water resistance, unidirectional rotating bezels, and — in later references — Omega's in-house Co-Axial escapement designed to reduce friction and extend service intervals. Pre-owned Omega watches are especially appealing because the brand manufactures at scale with consistent parts availability, meaning a well-serviced used example can deliver decades of reliable wear. Buying used also allows collectors to access discontinued references, earlier movement generations, or limited editions like the CK2998 reissue that are no longer available at retail.
What to Look For
When shopping used Omega watches in this collection, pay close attention to reference numbers, as subtle differences between numbers like 2201.50.00 and 2201.51.00 on the Planet Ocean indicate variations in dial texture or bracelet configuration, while the distinction between a chronograph Diver 300M such as 213.30.42.40.01.001 and a time-only Co-Axial like 212.30.41.20.01.002 significantly affects both complication depth and market value. Condition grading matters considerably — mint pre-owned examples command premiums over worn pieces — and for Speedmaster collectors, pre-moon references such as the 145.022-69 with its matte black dial and stepped case are historically significant and typically more valuable than later production runs.
Frequently Asked Questions
Are used Omega watches on Bizak and Co. authentic?
Yes, every used Omega watch listed at Bizak and Co. has been authenticated before being offered for sale. The collection includes verifiable reference numbers such as 310.32.42.50.01.001 and 2201.50.00 that can be cross-checked against Omega's official records, and the team inspects each piece to confirm genuine components and accurate representation of condition.
What is the difference between the Speedmaster Pre-Moon and the Moonwatch Professional?
The Pre-Moon designation refers to early Speedmaster references — such as the 145.022-69 — produced during or before the Apollo era, featuring matte black dials, pump pushers, and period-correct cases that differ cosmetically and mechanically from current production. The Moonwatch Professional, as seen in reference 310.32.42.50.01.001, is the modern interpretation that retains the same 42mm steel case and hesalite crystal option while incorporating updates to finishing and strap options. Pre-moon examples are generally more collectible and command higher premiums among enthusiasts.
Do used Omega Seamaster Diver 300M watches come with bracelets or straps?
It varies by reference — some Seamaster Diver 300M listings in this collection, such as the Co-Axial chronograph 2225.80.00, are described as coming on a steel bracelet, while others list leather or nylon fabric straps. Always review the individual product title and description carefully, as the included bracelet or strap is specified for each watch and can affect both usability and resale value.
