Omega Seamaster Diver 300m

For more than two decades, the Omega Seamaster Diver 300m collection has prided on having a legendary following. The collection was first released into the market in 1993. As the years went by, Omega kept on upgrading the Seamaster Diver 300m collections. The modern collection represents the best innovation and design from Omega infused with the heritage of the sea.


The Omega Seamaster Diver 300m model stands out with its blue color. The model contains revolutionary components, which offer buyers the highest caliber of performance. With the Diver 300m model, Omega has managed to conquer every challenge in designing an exquisite modern timepiece. The Omega Seamaster Diver 300m model comes in 26 variations.

The watch is a 42mm model and crafted with stainless steel. The case steel has a diameter of 42mm, which means the watch's face is quite big. The watch's bezel is ceramic blue and very stylish. The bezel has a white enamel diving scale. Like most Omega models, the Omega Seamaster Diver 300m model has a unidirectionally rotating bezel. This means the bezel rotates in only one direction. This feature is essential for divers who can't accidentally turn the bezel in the wrong direction. Pushing the bezel in the wrong direction can cause a diver to miscalculate the diving time.

The watch has an eye-catching dial. The dial of the 300m model is sun-brushed PVD chrome color ceramic and gray. The dial features an engraved wavy design. Just below the 12 o'clock sign, you can see the Omega logo. At 6 o'clock, the model has a date window, showing the date but minus the month and year. The back of the watch is transparent. With the transparent case, one can see the watch's mechanism. You can see the chronometer used in the watch's operation. The back case also has a wave edged design and is made from sapphire glass like the dial. The Geneva waves in arabesque combined with the rhodium-plated finish make the watch very stylish. The watch is anti-magnetic. This means the watch remains unaffected when exposed to high magnetic fields, as high as 1.5 teslas.

The dial has skeleton hands showing the hours, minutes, and seconds. The hands have been filled with the white Super-LumiNova. There are raised indexes on the dial and the outer circumference, and there are indexes showing the seconds. The dial is made from high-quality glass, which is a sapphire crystal. The sapphire crystal glass is domed, scratch‑resistant, and layered with anti-reflective treatments on all sides. The model has a helium escape valve, which has been crafted in a conical design. The valve uses a depression system that allows the helium to escape from the watch whenever the watch is worn for professional use and exposed to pressure chambers.

The watch comes in a stylish blue leather strap, but the case is made from stainless steel. The Omega 300m model allows buyers to experiment with different straps. The straps range from stainless steel straps to leather straps and even polyester straps. The watch comes with different combinations of straps. The watch has over 50 strap combinations. Some of the strap combinations available include:

  • Polyamide 5-stripe grey & blue strap
  • Golden brown Novonappa leather strap
  • Brown Novonappa leather strap
  • Grey polyester strap

The straps are sold separately and have different prices. All are available on the Omega official website.

There is a screw-in crown on the side of the watch. This is a self-locking crown, which is carefully screwed into the tubes of the case. This crown is only used in highly water-resistant watches. This Omega timepiece has a free sprung-balance caused by the silicon balance spring mechanism, and the self-winding movement has co-axial escapements. The watch has a power reserve of up to 55 hours.

The Omega Seamaster Diver 300m model has the OMEGA Master Chronometer Caliber 8800, and you can view the chronometer from the transparent back case of the watch. The chronometer of the model is Master Chronometer Certified. This certification means the model has the highest performance, magnetic resistance, and precision standards, which have been set by the Swiss Federal Institute of Metrology (METAS). The model has a high water resistance of 30 bar (300 meters / 1000 feet).

The watch comes with a five-year manufacturer’s warranty just like all the other Omega watches, and the warranty covers repairs of any defective materials. The operating manual has more information about the warranty.
