Omega Seamaster 300 Review: A Watch Fan’s Guide for 2023

The Omega Seamaster 300 is among the top dogs in the underwater game. It has made a name for itself over the years, not just for its impressive and modern design but for its excellent performance in and out of the seas as well.

It’s Omega’s answer to the Rolex Submariner and was modeled after the 1957 Seamaster 300 ref. CK2913. Some of the watches in the collection are part of Omega’s 1957 Trilogy series alongside the Railmaster and Speedmaster. Omega introduced an updated model in 2021.

Many changes have been made to the 2021 version, including Super-LumiNova illumination, a larger case, and others. The review below serves you a full-course meal of all the Seamaster 300 dive watches in detail. Let’s dig in.

The Case

Omega Seamaster 300 Case

The Omega Seamaster 300 is available in two case sizes:

  • 39mm
  • 41mm (2021 version)

The 39mm option was created with the professional diver with a smaller wrist in mind. It has less presence on the wrist and is lightweight with a screw-in crown. It’s slightly larger than the vintage ref.CK2913’s 38.5mm case size.

The 41mm alternative is bulkier (depending on the wearer), with quite a commanding wrist presence, fit for adventurers and divers with bigger wrists. It has a conical screw-in crown and strikes a perfect balance between comfort and sophistication, as we shall see below.

The Omega Seamaster 300 comes in a breathtaking array of case options aside from stainless steel:

  • Bronze Gold
  • Titanium-Sedna™ Gold
  • Platinum
  • Platinum-gold

All the cases have lugs decorated with a well-polished bevel on the side. They’re water resistant to 300m, making them ideal for high-impact water sports, scuba diving, and swimming. 

The 2021 varieties also have a transparent sapphire crystal case back that allows curious wearers to get a full view of the high-precision movement in action.

The Dial

Omega Seamaster 300 Dial

The Omega Seamaster 300 has a dial with an eye-catching design that sits directly between modern and classic. It’s protected by a (domed) scratch-resistant sapphire crystal with anti-reflective treatment and is available in several rich colors:

  • Black
  • Blue
  • Deep blue (made from lapis lazuli)
  • Blue enamel
  • Brown
  • Green (made from malachite stone) 

It provides a perfect contrast against the lume-applied hands and hour markers. 

The 2021 versions have a larger dial (an opening of 30.4mm) referred to as a ‘sandwich dial.’ This is because it consists of several plates, one with a sufficient amount of Super-LumiNova luminescence and the other with cut-outs for the Arabic numerals and indexes. 

It’s neat and highly legible and has a matte and slightly grained base. It uses Arabic numerals with triangles at 12, 3, 6, and 9 o’clock and index cut-outs for the rest. The digits at 6 and 9 have an open-type style (reminiscent of the Seamaster 300 in the ‘60s). It also has (PVD Bronze Gold, silver, yellow gold-plated) lume-applied hands, with the hour hand taking a faceted arrow shape.

The hour hand has blue emission. It reaches the bottom of the indexes and touches the numerals. Meanwhile, the sword-shaped minute hand extends to the top of the indexes and has green emission. 

It’s important to note that different models have varying designs for the seconds hand.

  • Some have an ordinary thin hand
  • Others have a lume-filled arrow at the tip 
  • The 2021 versions have a seconds hand with a small signature Super-LumiNova-filled circle (‘lollipop’) at the tip.

Some models’ dials have the word ‘Omega,’ its logo, and ‘Seamaster’ below 12 o’clock and the words ‘CO-AXIAL MASTER CHRONOMETER’ above 6 o’clock.

The 2021 models have the word ‘Omega’ and its insignia sitting under 12 o’clock (The 1957 Trilogy model has the word ‘Automatic’ under the Omega print). They also have ‘Seamaster 300’ printed above 6 o’clock, which is a clever improvement from the previous style.

The Movement

Omega Seamaster 300 Movement

Different models have different movements:

  • The 2021 models use the modern and automatic OMEGA Co-Axial Master Chronometer Caliber 8912. 
  • Others, like the limited edition ref. 233.93.41.21.03.001 have the anti-magnetic OMEGA Master Co-Axial Caliber 8401.
  • Others, such as the limited edition ref. 234.10.39.20.01.001, that’s part of the 1957 Trilogy series, contains the Master Chronometer 8806. 
  • Other watch models are powered by the OMEGA Master Chronometer Caliber 8913.

The OMEGA Co-Axial Master Chronometer Caliber 8912 is a large Master chronometer-certified (METAS) movement. It has a 60-hour power reserve, free-sprung balance with silicon balance spring, 38 jewels, and a 25,200vph frequency. It’s also resistant to magnetic fields of up to 15,000 gauss and has a twin-barrel design.

The OMEGA Master Co-Axial Caliber 8401 movement is pretty similar to the 8912 version. It’s an automatic movement with a Co-Axial Escapement that enhances its durability and precision. It’s also resistant to magnetic fields greater than 15,000 gauss and has 39 jewels, a 60-hour power reserve, and a 25,200vph frequency. Plus, the Co-Axial movement has a stylish finish with exclusive Geneva waves in arabesque.

The Master Chronometer 8806 was launched in 2017. It’s a self-winding movement with a free-sprung balance with silicon balance spring, 35 jewels, a 55-hour power reserve, and a 25,200vph frequency. It’s resistant to magnetic fields of up to 15,000 gauss. Although it’s not COSC-certified, it’s METAS approved and has a rhodium-plated finish with Geneva waves in arabesque.

Finally, the OMEGA Master Chronometer Caliber 8913 is a METAS-certified self-winding movement with a nice luxury finish. It winds automatically in both directions and, like the ones before it, is resistant to magnetic fields reaching 15,000 gauss. It boasts 39 jewels, a 60-hour power reserve, and 25,200vph frequency plus a finish with 18K Sedna™ Gold balance bridge and rotor with Geneva waves in arabesque.

All the above movements are significant improvements of the original’s 1955 movement (Caliber 500/501), which was also automatic but had some limitations. The Caliber 500 had 17 jewels, a 46-hour power reserve, and a 19,800vph frequency. On the other hand, the Caliber 501 had 19 jewels, a 46-hour power reserve, and a 19,800vph frequency.

The Bezel

Omega Seamaster 300 Bezel

Several bezel types can be found in the Omega Seamaster diver family:

  • Unidirectional rotating bezel- allows for adjustment in a counterclockwise direction only
  • Bi-directional rotating bezel- enables adjustment to clockwise and counterclockwise directions

Uni- and bi-directional rotating bezels are mainly helpful to scuba divers. The bezels’ 60-minute graduations represent 60 minutes in an hour. And they enable divers to measure how much time has passed underwater and how much oxygen is left in their scuba tanks.

The bezel colors depend on the color of the dial and sometimes the bracelet/strap. They have raised contours for easier adjustment, even with gloves and while underwater. Their rings are made from different materials, including:

  • Ceramic bezels
  • Ceramic and an 850-grade platinum LiquidMetal™ ring
  • Ceramic and a Ceragold™ ring
  • 18K Sedna™ Gold and a Ceragold™ ring and diving scale
  • Aluminum

The digits on their 60-minute diving scales are filled with different lumes. The most common ones are Super-LumiNova and Liquidmetal.

The 2021 versions have a thinner oxalic anodized aluminum bezel with graduations filled with vintage Super-LumiNova lume. The anodization process ensures the bezel is stronger than an ordinary aluminum bezel insert. The bezels maintain the 2-part design and look cleaner with a less congested scale and luminous dot.

The dot on the 2021 bezel rings has a green lume like the one on the minute hand. Meanwhile, the arrow-shaped hour hand and Arabic numeral/index hour markers have a blue lume along with the graduations on the bezel ring, giving the new watch an organized and beautiful look in the dark.

The Bracelet

Omega Seamaster 300 Bracelet

The bracelet/strap is one of the most crucial parts of a watch. It helps complete the overall look and binds the wearer to the watch in a comfortable hug. Omega Seamaster 300’s selection of bracelets and straps guarantees an unforgettable wearing experience.

They’re available in several options:

  • Stainless steel
  • Leather
  • Steel Gold
  • Gold
  • Platinum
  • Titanium 

The steel versions are well-polished and have three-piece links. They have polished center links, and brushed outer links. They also have a foldover clasp with comfort setting and the Omega logo. They’re also well-brushed, durable, and strong.

The 2021 versions have a stainless steel bracelet and leather strap. Omega has made a noticeable adjustment on the steel bracelet: Its center links are brushed, and external links are polished. The bracelet has a smoother and lighter feel thanks to the thinner, polished twin trigger deployant clasp with the Omega logo and fine adjustments and streamlined fittings.

Next is the leather bracelet, which is simple and deliciously casual. It’s either stitched non-grained calf or alligator- depending on the model- with a foldover or tang buckle clasp.

The 2021 versions’ leather bracelets are brown non-grained and single-stitched calf leather, with a pin buckle steel/ Bronze Gold clasp with the Omega logo.

The Steel Gold bracelets are a combination of steel outer links and Gold center links. The gold is either Yellow Gold or Sedna Gold™. They all have a foldover clasp with a comfort setting.

The platinum bracelet pairs with the platinum case for a formal and classy monochrome look for the bold and modern gentleman looking to stand out. It has nicely polished and brushed links and a foldover clasp with a comfort setting.

Lastly, the Titanium-Gold combo consists of a bracelet with Titanium external links and Sedna™ Gold center links. It has a thin foldover clasp with a comfort setting.

Note: The 2021 versions are available in three forms at the moment: 2 stainless steel options with a black and blue dial and 1 Bronze Gold variety. They come in luxurious steel bracelet and leather strap options. Let’s examine the Bronze Gold option in a bit more detail.

The Bronze Gold alloy used in its case and buckle is enriched with noble elements like silver and palladium as well as 37.5% gold. You can be sure you’ll enjoy its beautiful soft pink patina for years since it’s corrosion-resistant. 

Omega used the common bronze alloy in a dark brown color for the dial. The hue was obtained after a special aging procedure had occurred. The domed sapphire crystal over the dial gives it an excellent finish. Pair this with an exclusive thin brown ceramic bezel with vintage Super-LumiNova lume, and you have a handsome watch with a winning combination.
