Omega Seamaster Diver 300 M

A Diving Watch for Professionals With A Helium Escape Valve

80 meters - that was the world record for freediving in 1993. In 1993, Frenchman Roland Specker set a new freediving world record of 80 meters (262 ft) with the Omega Seamaster Diver 300M on his wrist. It came shortly after Omega had launched this watch alongside a chronograph edition. Both models were the first Omega watches with a helium escape valve, which enables professional saturation diving. Just like its famous sibling, the Seamaster 300, the Diver 300M is water resistant to 300 meters (30 bar, 984 feet).

In contrast to the Seamaster 300, the Diver 300M has a date display and a notably more modern design. The bezel in particular, with its wavy edge, gives the watch a special look. The dial, which is available in different colors, is usually adorned with a characteristic wave pattern. The broad sword-shaped skeleton hands are another trademark of the Diver 300M.

At the time of going to press in summer 2025, Omega is offering the timepiece in 42-mm, 43.5-mm, and 44-mm sizes, with the case predominantly made of stainless steel. Titanium, ceramic, gold, and two-tone variants in gold and stainless steel are also available. Platinum and the very rare tantalum are also used in a few models.

Omega only uses mechanical calibers for their more recent models. These movements are not only chronometer-certified, but also have been equipped with Omega's co-axial escapement since 2006. Most calibers are also certified Master Chronometers, meaning they can resist magnetic fields of up to 15,000 gauss.

All these benefits also seem to have convinced James Bond, because in the 1995 film GoldenEye, the British double agent played by Pierce Brosnan wears a Seamaster Professional 300M for the first time - back then still with a quartz movement. 25 years later, Bond still swears by a Diver 300M in the film No Time to Die , although this time with an automatic Co-Axial Master Chronometer movement and titanium case.

The timepieces are available in stainless steel, in two-tone, or with a proprietary rose gold case, which Omega calls Sedna gold. Common to all variants is a dial with a bicompax layout and subdials at 3 and 9 o'clock. Depending on the reference, the Omega Co-Axial caliber 9900 or 9901 serves as the regulating mechanism.

The variant with the reference number 210.30.44.51.01.001 is an example of one of the stainless steel models. The dial of this watch is black, and a five-link stainless steel bracelet holds the watch securely on the wrist. The reference 210.30.44.51.03.001 has a blue dial.

Buying the Seamaster Diver 300M GMT

If you are looking for a GMT watch without a chronograph function, you should take a closer look at the now-discontinued reference 2534.50.00. Omega produced this model from the late 1990s to the end of the 2000s. Due to this production period of around ten years, you will find numerous examples on the used market. Defining features include luminous sword hands and wedge indices, as well as a black and silver bidirectional bezel with a 24-hour scale. The stainless steel case measures 41.5 mm. Like the three-handed model, the GMT version is water resistant to 300 meters (30 bar, 984 feet), and does not have a helium escape valve.

Thanks to the automatic Omega caliber 1128, you can set the hour hand independently of the minute, seconds, and 24-hour hands. This is especially practical when traveling across time zones. Omega developed this movement based on the ETA 2892-A2. The 1128 is a certified chronometer. It features a power reserve of 44 hours.

The Seamaster Diver 300M ref. 2535.80.00 is one of the newer GMT watches in the collection and comes equipped with Omega's Co-Axial caliber 2628. This movement is based on Omega's first Co-Axial caliber, the 2500. With its helium escape valve at 10 o'clock and 60-minute bezel, this model looks more like a diving watch than a GMT. The 24-hour scale for keeping track of the time in a second time zone is embedded into the dial, next to the hour indices.

James Bond and the Seamaster Diver 300M

The Diver 300M made its debut on the silver screen in 1995 as James Bond's timepiece in the movie GoldenEye. Since then, Omega has produced several limited and standard-edition James Bond watches.

The most recent example is the No Time to Die from 2020. The 42-mm titanium watch combines modern elements such as the Master Co-Axial Chronometer movement 8806 with retro elements such as a domed sapphire crystal cover glass and luminous material with a vintage look. Omega worked with actor Daniel Craig, who portrays the secret agent in the film, to design this Seamaster Diver 300M 007 Edition. This watch features a brown dial and brown aluminum bezel inlay. There's also a "Broad Arrow" on the dial and case back. The British government uses this symbol to mark government-owned property. This underscores the military flair of this Bond watch.

Omega offers the No Time to Die on a fine Milanese bracelet or NATO strap. The latter variant can be found under the reference number 210.92.42.20.01.001. The version with a titanium Milanese bracelet bears the reference number 210.90.42.20.01.001.

In the fall of 2024, Omega presented two more models of the Seamaster Diver 300M, reminiscent of the "No Time to Die" Bond watch. The watches are available with a gray or black dial. Unlike the Bond model, the cases of these variants are made of stainless steel rather than titanium. The watch with the reference number 210.30.42.20.06.002 has a gray dial and is worn on a Milanese bracelet. Under the reference 210.32.42.20.06.002, you will find the watch on a black rubber strap. The reference 210.30.42.20.01.010 has a black dial and is fitted with a Milanese bracelet, while the variant with the reference number 210.32.42.20.01.003 is worn on a rubber strap.

If you prefer two-tone titanium and the bronze-gold developed by Omega, you should take a closer look at the Omega Seamaster Diver 300M (ref. 210.90.42.20.10.001). The case of this watch is made of titanium, while the bezel, crown, and helium escape valve are made of bronze-gold. The dial and bezel insert are a rich green and also feature gold accents on the indices, hands, and diving scale. The watch is available on either a titanium Milanese bracelet or a green rubber strap.

At the beginning of 2025, Omega presented a Bond-style Seamaster Diver 300M under the reference number 210.90.42.20.01.003, whose case and bracelet are made entirely of bronze-gold. Another striking feature of this black-dial watch is its burgundy-colored bezel. Under the reference 210.92.42.20.01.003, you will find the model on a black rubber strap.

Alternatively, you can also opt for the Diver 300M James Bond Limited Edition set. This contains the 210.22.42.20.01.003 in stainless steel and the ref. 210.62.42.20.01.001 in gold. Both timepieces have a black dial featuring a pattern based on the famous gun barrel sequence from the Bond films. The 12 o'clock marker on these watches is shaped like the Bond family coat of arms. The set is limited to 257 pieces.

Seamaster Diver 300M "Commander's Watch," ref. 300.300.300.300.300.300

The Commander's Watch is also a Diver 300M dedicated to Her Majesty's secret agent. Its name is a reference to Bond's military rank in the Royal Navy. The Commander's Watch has a 41-mm stainless steel case, a blue bezel with the first 15 minutes in red, and a white ceramic dial. Another nice detail is the second hand's counterweight, which is in the shape of the 007 logo. What's more, the rotor resembles the casing bottom of a 9-mm bullet and also features the secret agent's logo. All this is visible thanks to a sapphire crystal case back. Omega pairs this timepiece with a NATO strap in blue, red, and gray – the colors of the Royal Navy. Omega produced only 7,007 pieces of the ref. 212.32.41.20.04.001.

Casino Royale and James Bond^50th Anniversary

Other James Bond watches from Omega are the Seamaster Diver 300M Casino Royale and the Diver 300M James Bond^50th Anniversary. The latter has the reference number 212.30.41.20.01.005. You can recognize this model by the red 50 on the black ceramic bezel and the dial, which is adorned with numerous 007 logos. The case diameter of the stainless steel watch is 41 mm.

The Seamaster Diver 300M from the film Casino Royale looks like a typical diving watch with its black dial and luminescent indices, black rotating diving bezel, and lumed bezel pip. The 007 logo on the seconds hand counterbalance and case back however reveal that this is the James Bond ref. 212.30.41.20.01.001. Omega limited this model to 10,007 pieces.

Olympic Diver 300Ms

Omega has been the official timekeeper of the Olympics for years, and the brand from Biel has continued to honor the games by releasing special Olympic editions of their watches, including the Diver 300M.

One example is the Rio 2016 Limited Edition. The black ceramic bezel on this timepiece features numerals in the colors of Olympic rings, and the wave pattern on its black dial is inspired by the wide walkways of the world-famous Copacabana.

Omega created the Diver 300M ref. 522.30.42.20.03.001 for the 2022 Winter Olympics in Beijing. This stainless steel watch comes with a brushed titanium bezel, and the hour markers on its blue dial are in the official Olympic colors. The movement inside is the Master Chronometer caliber 8800.
