Omega's origins date to 1848, when Swiss watchmaker Louis Brandt first set up shop in La Chaux-de-Fonds, Switzerland. What began as a small assembly operation grew into one of the most historically significant watch manufactures in the world, supplying over 100,000 timepieces to British forces during the Second World War and going on to become the official timekeeper of the Olympic Games, NASA's choice for crewed spaceflight, and the watch brand most closely associated with James Bond. At Bo Knows Luxury, every pre-owned Omega in our collection has been authenticated, pressure-tested, and mechanically validated, backed by our one-year in-house service warranty at no additional charge.

A Manufacture Built on Firsts

In 1948, Omega launched the Seamaster, a watch that began life as a water-resistant dress watch and quickly morphed into a broader collection including a fully capable dive watch in the form of the Seamaster 300. 1957 saw the release of the first Speedmaster, a watch commonly associated with the space race but whose design was inspired by automotive racing. Following its appearance on the wrist of Buzz Aldrin during the 1969 moonwalk — and its role in saving the crew of Apollo 13 in 1970 — the Speedmaster became a household name, bringing heretofore unknown fame to the Swiss company.

Introduced in 1957, the Speedmaster became the chronograph against which others were measured. It was the first to move the tachymeter scale from the dial to the bezel, which improved legibility, and its tough build was a large part of why NASA chose it. That NASA qualification story remains one of the most compelling in watchmaking. Omega submitted the Speedmaster for testing in 1965 alongside watches from several competing manufacturers. The Speedmaster was the only reference to survive all eleven test categories intact, and it was formally certified for all crewed space missions in March 1965. Four years later, it went to the moon.

What Makes Omega Distinct

The Co-Axial Escapement. In 1999, Omega became the first manufacturer to commercially produce a watch using the Co-Axial escapement, a mechanism developed by master watchmaker George Daniels that fundamentally reduces friction in the escapement by separating the locking and impulse functions. Less friction means less lubrication required, longer intervals between services, and more consistent timekeeping over the life of the watch. The Co-Axial escapement is now used across virtually the entire Omega lineup and is the single most significant movement innovation in mainstream Swiss watchmaking since the development of the lever escapement in the 18th century.

Master Chronometer Certification. METAS, the Swiss Federal Institute of Metrology, certifies Omega's Master Chronometer-designated movements to eight criteria including accuracy, magnetic resistance, power reserve, and water resistance. The most notable standard is magnetic resistance to 15,000 Gauss, the strongest anti-magnetic specification of any mainstream Swiss watch manufacture. Standard COSC chronometer certification requires only that a movement resist 4,800 A/m (approximately 60 Gauss). A METAS-certified Omega movement is 250 times more resistant to magnetism than a standard chronometer.

Value Positioning. Omega occupies a unique position in the watch hierarchy: high enough in manufacturing quality and historical prestige to be considered a serious collector brand, accessible enough in price that pre-owned examples represent genuine value across a broad range of budgets. A pre-owned Speedmaster Moonwatch with box and papers can be acquired for $4,500 to $6,500. A pre-owned Seamaster Diver 300M in steel sits between $3,500 and $5,500. No other brand at this price point offers the same combination of in-house movement architecture, METAS certification, and documented historical significance.

The Omega Collections Explained

Speedmaster Professional Moonwatch (Ref. 310.30.42.50.01.001, 310.30.42.50.02.001). The Moonwatch is the most historically significant watch in Omega's catalog and one of the most collected references in the entire pre-owned market. The current generation runs the Calibre 3861, a manual-wind movement with a Co-Axial escapement and Master Chronometer certification, delivering 50 hours of power reserve at 21,600 vph. The ref. 310.30.42.50.01.001 features a black dial with a Hesalite crystal and aluminum bezel insert, staying closest to the original NASA-qualified configuration. The ref. 310.30.42.50.02.001 substitutes sapphire crystal and a ceramic bezel insert. Both references retail at approximately $7,400 new; pre-owned examples with box and papers trade between $5,500 and $6,500 depending on condition and generation.

Speedmaster First Omega in Space (Ref. 311.32.40.30.01.001). The First Omega in Space resurrects the model worn by Wally Schirra when he orbited the Earth in the 1962 Sigma 7 mission, staying faithful to its ancestor's 39.7mm dimensions, straight lugs with thin bevels, lack of crown guards, and the relief-engraved seahorse emblem on the caseback. It runs the manually wound Calibre 3861 and is a numbered rather than strictly limited edition, meaning each piece carries an individual serial number on the caseback. Now discontinued, pre-owned full-set examples are the only path to ownership.

Seamaster Diver 300M (Ref. 210.30.42.20.01.001, 210.30.42.20.03.001). The Diver 300M is the quintessential Omega sport watch, worn by James Bond since 1995's GoldenEye and rated to 300 metres of water resistance with a unidirectional rotating ceramic bezel. The current generation runs the Calibre 8800, a Co-Axial Master Chronometer automatic with 55 hours of power reserve and a free-sprung balance with silicon balance spring. Available in black dial (ref. 210.30.42.20.01.001) and blue dial (ref. 210.30.42.20.03.001) on a steel bracelet. The No Time To Die limited edition ref. 210.90.42.20.01.001 in Grade 2 titanium with a brown tropical dial is among the most collectible current-generation Seamasters on the pre-owned market.

Seamaster Planet Ocean (Ref. 215.30.44.21.01.001). The Planet Ocean is Omega's professional dive watch, rated to 600 metres with a helium escape valve for saturation diving applications. The current 43.5mm generation runs the Calibre 8900 Co-Axial Master Chronometer with 60 hours of power reserve. Pre-owned first and second generation Planet Ocean examples, including the 2201.51.00 with its distinctive orange numerals, trade at a significant discount to new pricing and represent strong value for buyers who want genuine dive specification at an accessible pre-owned price.

Seamaster Aqua Terra (Ref. 220.10.41.21.03.001). The Aqua Terra is Omega's everyday sport-dress crossover, designed with a teak-pattern vertical dial stripe, a 150-metre water resistance rating, and a bracelet that transitions between formal and casual wear. The current generation runs the Calibre 8900 Co-Axial Master Chronometer. The Aqua Terra is the least discussed Seamaster variant but arguably the most versatile daily wearer in the entire Omega lineup.

Constellation (Ref. 131.10.39.20.02.001). Launched in 1952, the Constellation is Omega's dress collection, defined by its clawed bezel, integrated bracelet, and cleaner dial aesthetic than the sport-oriented Seamaster family. The current Constellation runs the Calibre 8800 Co-Axial Master Chronometer at 39mm. Steel and gold two-tone configurations are the most widely traded on the pre-owned market. The Constellation occupies the same position in the Omega catalog that the Datejust occupies at Rolex: an elegant, versatile everyday dress watch at a more accessible price point than the brand's flagship sport references.

Omega Movements: What to Know

Omega's movement architecture divides into three tiers relevant to pre-owned buyers.

ETA-sourced movements (pre-2007). The majority of pre-owned Omega references encountered on the secondary market run modified ETA base movements. These include the 1120 (Aqua Terra), the 1164 (Seamaster), and the 2500 series Co-Axial movements used in Seamasters from approximately 2007 through 2014. ETA-based references are reliable, widely serviced, and significantly less expensive to maintain than current-generation manufacture movements.

Co-Axial manufacture movements (2007 to 2015). The 8500 and 9300 series movements represent Omega's first generation of fully in-house Co-Axial calibres. The 8500 powers the Aqua Terra; the 9300 powers the Speedmaster automatic. These movements deliver improved accuracy and longer service intervals versus ETA-based predecessors, and represent the sweet spot on the pre-owned market between cost and specification.

Master Chronometer movements (2015 to present). The 8800, 8900, and 3861 series are METAS-certified Master Chronometer calibres with silicon balance springs, 15,000 Gauss magnetic resistance, and extended power reserves. The 3861 in the Moonwatch Professional is manually wound; the 8800 and 8900 are self-winding. These are the current-generation references and command the strongest pre-owned premiums.
