The Seamaster series is among the most comprehensive collections in the Omega catalog. Prices largely depend on the exact model. This is especially true of the Seamaster 300, which has been in production since 1957. The Seamaster 300 is a classic diving watch with three hands, luminous indices, a unidirectional bezel, and water resistance to 300 m (30 bar, 984 ft). Little has changed about its design since its introduction. Defining features include triangular hour indices; Arabic numerals at 3, 6, 9, and 12 o’clock; and an arrow-shaped hour hand.
The current Seamaster 300 measures 41 mm in diameter and is available in multiple colors and materials. Cases come in stainless steel, titanium, platinum, and several gold alloys. In 2021, Omega added bronze gold to this lineup; made by mixing bronze with gold (37.5%), silver, and palladium, this alloy is corrosion-resistant and hypoallergenic.
The standard Seamaster 300 comes with a black dial and bezel, but if you’d prefer something a bit more colorful, the watch also comes in blue or green. Regardless of the color, you’ll find Omega’s certified Co-Axial Master Chronometer caliber inside.
Plan to pay about 5,400 USD for a stainless steel Seamaster 300 on a leather strap. The same watch on a stainless steel bracelet will cost you an additional 300 USD. Models in titanium usually change hands for between 6,300 and 6,600 USD, depending on the strap or bracelet. Two-tone editions in stainless steel and gold sell for around 9,500 USD on Chrono24; editions in titanium and gold go for somewhat less, approximately 8,500 USD. If you’re looking for a watch in yellow or rose gold on a matching bracelet, prices climb to between 26,000 and 27,000 USD. The same watch on a leather strap costs considerably less, between 15,400 and 16,700 USD. The prices for a platinum Seamaster 300 start around 30,000 USD.
Due to its long history, you’ll find plenty of vintage Seamaster 300 models on the market. Collectors are especially fond of Seamasters from the 1960s, like the ref. 166.024, for example, which you can purchase on Chrono24 for about 8,400 USD. A well-maintained original Seamaster 300 with the reference number CK 2913 will cost you between 15,500 and 32,000 USD. You can save yourself thousands of dollars by purchasing the Seamaster 300 from the 1957 Trilogy instead. This model debuted in 2017 and combines the original’s design with a modern Co-Axial Master Chronometer caliber. This particular watch demands an investment of roughly 6,800 USD.
The Seamaster Diver 300M
Omega launched the Seamaster Diver 300M in 1993. This model has a much more modern feel than the Seamaster 300. It features a diving bezel with a scalloped edge, a wave-pattern dial, and wide, skeletonized sword hands. The dial is available in several colors, including blue, black, white, and silver. Omega expanded the selection in 2022 by adding a dial in olive green.
Another detail not found on the Seamaster 300 is the helium escape valve on the case at 10 o’clock. This mechanism protects the watch against potential damage caused by helium molecules entering the case during saturation diving. The Diver 300M’s case is water-resistant to 300 m (30 bar, 984 ft) and available in stainless steel, titanium, gold, or ceramic.
Over the years, Omega has offered the Seamaster Diver 300M in an array of sizes ranging from 28 to 44 mm. The three-hand variant in the current collection comes in stainless steel or titanium and measures 42 mm in diameter; the ceramic edition is somewhat wider, measuring 43.5 mm. Regardless of the size, Omega has equipped both versions with chronometer-certified automatic movements with co-axial escapements. Older editions of the Diver 300M, such as the first-gen ref. 2531.80.00, come with an ebauché movement from Swiss manufacturer ETA. Quartz movements are also still part of the Seamaster repertoire, as evidenced by the 28-mm women’s watch without a helium escape valve.
This last watch is also the most affordable model, and changes hands for about 1,700 USD. For a first-generation edition with an automatic caliber, expect to pay about twice that. The current Master Chronometer model in stainless steel goes for around 4,400 USD. Prices increase as soon as precious metals come into play. A two-tone timepiece in stainless steel and gold on a rubber strap, for example, costs approximately 6,000 USD. By comparison, the same watch on a two-tone link bracelet costs nearly 9,200 USD. Models in titanium and rose gold cost another 2,500 USD more. If you’d prefer a gold watch, plan to spend at least 20,000 USD. If you’re not in the market for a watch in stainless steel, gold, or titanium, prices for the 43.5-mm Diver 300M in black ceramic start around 7,000 USD.
The Diver 300M Chronograph
In addition to three-hand timepieces, the Diver 300M is also available as a chronograph. Omega offers models with two or three subdials, as well as versions with a GMT function. You can purchase the 44-mm watch with three subdials for as little as 4,400 USD on Chrono24. However, these timepieces lack the distinctive wave pattern on their dials, and the caliber 3330 inside is not a certified Master Chronometer.
This is also true of the Diver 300M GMT Chronograph, fitted with the caliber 3603. You’ll easily recognize this watch by its additional GMT hand and the 24-hour scale at the outer edge of the dial. Plan to shell out about 5,400 USD for a Diver 300M GMT.
Omega equips its bicompax watches with the ultramodern Co-Axial Master Chronometer caliber 9900, which boasts a power reserve of 60 hours and is anti-magnetic up to 15,000 gauss. Stainless steel editions cost around 6,500 USD, while prices for two-tone timepieces in gold and steel range between 8,800 and 11,700 USD. The model released in mid-2021 in titanium, rose gold, and tantalum demands upwards of 18,000 USD; the solid rose gold edition sells for around 23,500 USD.
