Omega Seamaster Diver 300m Watch Review

Omega is a highly reputable watch brand that has held a high standing in the watchmaking industry for decades.

The Omega Seamaster is meant to be worn as a sports watch. It is durable and can withstand high-pressure water; thus, it is often used by deep underwater divers.

For several years Omega did not change much within their Seamaster collection, but at the 2018 Baselworld exposition they released one of their most famous watches, the Omega Seamaster Diver 300m

Omega Seamaster Diver 300m 210. 22. 42. 20. 03. 001

The Omega Seamaster Diver 300m was one of two Omega watches released in 2018. This watch became extremely well known for its ability to withstand high water pressure as well as its stunning design. While the watch was made primarily for divers, it can also be worn as a formal attire accessory.


The Omega Seamaster Diver 300m is made of stainless steel and 18k yellow gold. The stainless steel is relatively scratch resistant, and the addition of 18k yellow gold adds luxury.

The bezel of this watch is made of blue ceramic, which blends with the watch's overall blue theme. On top of the bezel all the features have been engraved using a laser, and the date can be seen displayed at the 6'o clock position.

The hands and the raised indexes of the watch are also made from 18k yellow gold and are filled with white Super-LumiNova. The addition of the 18k yellow gold brings a contrast to the overall blue design.

The watch features a blue rubber strap which allows for comfortable wear while ensuring that the watch is secure when worn.

The watch is made with domed, scratch-resistant sapphire crystal. The glass has anti-reflective treatment on both sides, which causes less eye strain.


The Omega Seamaster Diver 300m features an Omega Master Chronometer caliber 8800, which is visible through the sapphire crystal on the case back. The Omega Master Chronometer caliber 8800 is made completely of steel with no addition of precious metal. A chronometer is an instrument that allows time to be measured accurately regardless of pressure, humidity, or temperature.

This timepiece has 35 embedded jewels and a power reserve of 55 hours with a frequency of 25'200vph. It comes with helium escape valves and features a unidirectional rotating bezel. The unidirectional rotating bezel allows the bezel to only turn in one direction; this is helpful for divers because it ensures that they will not mistakenly rotate the bezel in the wrong direction, which would cause miscalculations for their dive timings.

Magnetic and Water Resistance

The Omega Seamaster Diver 300m has an anti-magnetic feature, meaning the watch is not affected by magnetic fields that could otherwise interfere with its mechanics. This watch can withstand magnetic fields as strong as 15,000 gausses (1.5 teslas).

The water-resistance of this watch goes up to 300 meters (30 bar or 1000 feet), which is one of the things that makes it such an exceptional dive watch.


The sports industry is constantly looking for new and innovative products, and Omega has made its mission to fulfill this demand. While not every brand is capable of creating watches for both sportswear and formal wear, Omega has proven that both can be achieved in just one watch.
