The “Omega Seamaster Diver 300M Chronograph Ref. 2225.80.00 Watch Review” provides a detailed analysis of this timepiece by WatchBox Reviews. The review covers various aspects of the watch, including its specifications, design, and functionality. The Omega Seamaster Diver 300M Chronograph Ref. 2225.80.00 features a stainless steel case with a unidirectional diver’s bezel and a scratch-resistant sapphire crystal. The blue ocean-wave guilloche dial has luminous hour indices, contrasting-texture subregisters, and a date aperture. This watch is powered by the COSC-chronometer certified self-winding Omega 1164 caliber and comes with a stainless steel bracelet with a folding clasp and dive extension.

Case and Dial

The stainless steel case of this watch is durable and adds a touch of elegance to its overall appearance. It is resistant to corrosion, ensuring longevity and reliability for the wearer. The unidirectional diver’s bezel not only adds a sporty touch to the watch but also serves a practical purpose for divers, allowing them to keep track of their elapsed time underwater.

Protecting the dial is a scratch-resistant sapphire crystal, ensuring that you can enjoy your watch without worrying about unsightly scratches. The blue ocean-wave guilloche dial is a standout feature of this timepiece, giving it a unique and eye-catching look. The applied luminous hour indices not only enhance readability in low-light conditions but also add a touch of sophistication to the watch.

The printed white minute calibrations on the outer edge of the dial provide convenient reference points for precise timekeeping. One notable feature of the watch is the contrasting-texture subregisters, adding depth and visual interest to the dial. At the 3 o’clock position, a date aperture is conveniently placed for easy reference. The partly skeletonized center hands with luminous fills not only add to the overall aesthetic appeal of the watch but also enhance legibility in low-light conditions.


Powering this timepiece is the self-winding Omega 1164 caliber movement. This movement has been certified by the COSC as a chronometer, indicating its exceptional accuracy and precision. With a 44-hour power reserve, the watch ensures that it will keep ticking for an extended period, even when not in use.


The stainless steel bracelet of this watch is crafted with quality and durability in mind. It seamlessly integrates with the case, creating a cohesive and elegant look. The folding clasp adds convenience and security, ensuring that the watch stays securely on your wrist. For divers or individuals with larger wrists, the bracelet also features a dive extension, allowing for easy adjustment and a comfortable fit.

With a case diameter of 41.5mm, this watch strikes the perfect balance between being substantial and not overly oversized. The 17mm case thickness adds to its robust and masculine appeal. When worn on a NATO strap, the lug to lug measurement is 49.5mm, making it suitable for a variety of wrist sizes. On the stainless steel bracelet, the lug to lug measurement increases to 55mm, providing a comfortable and secure fit for individuals with larger wrists. The watch is designed to fit wrists as small as 14.5cm in circumference, ensuring that it can accommodate a wide range of wearers.

Bracelet Design and Comfort

The stainless steel bracelet is not only aesthetically pleasing but also designed for maximum comfort. It is lighter and more delicate than a Rolex 3-link oyster bracelet, ensuring that it is comfortable to wear for long periods. The broad channels between the links prevent pinching of the skin or pulling of hair, making it a joy to wear throughout the day. The high-quality clasp with deploying guide extension adds convenience and ease of use, allowing for quick and secure fastening.

Case Design

The case design of this watch is both functional and visually appealing. It strikes the perfect balance between being substantial and not overly bulky. The beautiful polished bevels contrasting with the satin case finish give the watch an elegant and refined look. The iconic helium release valve, a signature feature of Omega’s professional diving watches, adds to its sporty appeal.

The unidirectional bezel is easy to turn and features a positive detent and audible ratchet, ensuring precise and accurate time tracking underwater. The case design not only enhances the watch’s functionality but also adds to its overall aesthetic appeal.

Dial Upgrades

Compared to older models, this watch features several dial upgrades that elevate its overall quality and appearance. One notable enhancement is the addition of applied Omega Marquis, adding to the premium feel of the watch. The higher dial quality, along with the applied indices, enhances legibility and gives the watch a more luxurious and refined look.

Movement and Features

Powered by Omega’s adapted version of the Valjoux 7750 movement, the Caliber 1164, this watch offers exceptional performance and reliability. In addition to its chronometer certification, indicating its outstanding accuracy, the movement boasts a 44-hour power reserve, ensuring that the watch will continue to keep time accurately for an extended period. The hacking seconds feature allows for precise time setting, while the quick set for the date adds convenience and ease of use.

Toughness and Reliability

This watch is a pre-coaxial model, known for its exceptional toughness and reliability. It is considered one of Omega’s toughest chronographs, comparable to the renowned Speedmaster Professional. Its mechanical architecture ensures that it can withstand the demands of everyday wear and various activities. With its exceptional accuracy and water resistance, this watch is built to last and perform reliably in any situation.
