Omega Seamaster Diver 300m Watch Review

Omega is one of the world's most famous watch brands. It has enjoyed an excellent reputation around the world and has been featured in several movies. For decades, Omega has been trusted to make some of the most innovative watches for regular use and professional sportswear.

Omega Seamaster Diver 300m has been around for decades now and has a dedicated following of its own. In recent years, the Seamaster Diver 300m watches have enhanced their reputation. They have become one of the most successful collections of watches used by professional divers and stylish individuals.

The Omega Seamaster Diver 300m was a part of Omega's successful collection that celebrated its 25th anniversary in 2018. This watch was meant to show off Omega's most innovative idea to date.

With the appearance and audience in mind, Omega made sure to bring forth a design that could outperform other watches available in the market. While the Omega Seamaster Diver 300m has several watches that make use of it, the Omega Seamaster Diver 300m was claimed to be the most loved watch due to:


Omega Seamaster Diver 300m 210. 20. 42. 20. 03. 002 is made of stainless steel and 18k SednaTM Gold. Using stainless steel for the making of the majority of the watch case gives more room for better craftsmanship and allows the watch to be resistant to scratches. The 18k SednaTM gold adds to the watch's luxurious appearance and allows for better durability.

The case also features a blue ceramic bezel; this blue bezel contrasts stunningly with the watch's gold details. The blue bezel also matches the watch's polished blue dial, which has waves engraved through the use of a laser. You can also easily view the date window at the 6 o'clock mark.

The watch's overall combination of gold with stainless steel is matched with the watch's hands and raised indexes, which are 18k SednaTM gold. They have then been filled with white super LumiNova; this white super LumiNova emits blue-green light in the dark.

The Omega Seamaster Diver 300m has a bracelet that is also 18k SednaTM gold and stainless steel. This gives the watch an overall put together look, which allows it to be worn at formal events.

The watch has a glass made from sapphire crystal, which has a dome shape. It has anti-reflective treatment on both sides, allowing more light to enter the wearer's eyes, causing less strain. The glass is also scratch-resistant, allowing it to be worn at sports events without being worried about ruining it.


The Omega Seamaster Diver 300m is driven by Omegas's famous Calibre, the OMEGA Master Chronometer Calibre 8800. This Calibre can be viewed through the sapphire crystal on the case's back. Omega's Master Chronometer Calibre 8800 is made up of complete steel without any gold or other precious metal.

The watch also features a conical design helium escape valves, which allow the watch to release helium when used for professional reasons, such as when entering any pressure chambers. The watch has also undergone several tests to ensure that no external environment causes any issues with the watch, which is why it features a chronometer.

To further add to this watch's luxury appeal, it has the added feature of a unidirectional rotating bezel. This bezel allows for the watch's bezel to rotate only in one direction.

Magnetic and Water Resistance

The Omega Seamaster Diver 300m has magnetic resistance, which allows the watch's inner workings not to be disturbed due to external magnetic fields that would have caused issues with the spring balance. This watch also has water resistance up to 30 bars (1000 feet or 300 meters). Having a water resistance bar this high allows for professionals to use it for deep-water diving purposes.


While Omega may not be one of the oldest watch brands out there, it is still one of the most innovative watchmaking industry brands. Their ideas have left people astonished due to their unique designs and their constant upgrading of their watches.
