Omega Seamaster Professional 300m 2254.50


This is a review about the Omega Seamaster 300 2254.50. The watch was sold along the ‘Bond’ Seamaster 2531.80 and its differences to the 2531.80 are sword hands, indices, bracelet, colors and big triangle dial. The “big triangle” on the dial along with the rectangular indices are a throwback to the classic 166.024 and 165.024 Seamasters.

Basic information

The distinctive features of the 2254.50 are its thinness, sword hands and speedmaster style bracelet with slight taper to the clasp.

However, to keep Omega references complex, Omega released a few other similar, but different models, such as the 2255.80 electric blue and steel, 2533.50 America’s cup with black dial and steel and the 2054.50 which nearly identical to the 2254.50, but mounted on the 5-link Bond bracelet.

Hand-winding Experience

The Omega cal 1120 derived from ETA 2824-2 is a workhorse and can be enjoyed for its utilitarian aspects. It is neither pretty or advanced, but it does the job.

The hand-winding experience of the 2254.50 is close to standard ETA 2824-2. There is really nothing new to anyone who has handled an ETA 2824-2. While the winding experience is relatively far away from the modern luxury watches, the watch gives satisfiable clicks to notify when it has been fully wound.

Nato Strap

The 1610/930 bracelet of the 2254.50, even with its modest taper, may not be for everyone. For a person with a smaller wrist, it can fear bulky and cumbersome. The 2254.50 is a relatively thin watch. Because of its 11mm thickness, it wears perfectly on a nato strap. With a slim 1mm thick nato strap the watch wears only 14mm on a nato strap with a keeper. This is still 0.5mm thinner than a Planet Ocean cal 2500.

Due to the thinness of 2254.50 it is possible to use some of the thicker Nato straps with Keepers, such as Blushark Orca. Even with a 1,5mm thick waffle weave Orca, the 2254.50 is at 14mm of thickness. This is still 1,5mm thinner than a cal 8500 PO.

My preference is to wear it on a Nato strap over the excellent Speedmaster-style bracelet. Luckily, most watches come with the bracelet, so you can decide for yourself.

Mods and part numbers

Non-America’s Cup Dial: In this mod, the dial of the 2254.50 is changed to the Non-America’s Cup Dial. In this dial the indices and Omega text are applied vs painted / printed.

Planet Ocean Seconds Hand: In this mod the second hand is changed to PO seconds hand which some think fits better the sword hands. Also the tip of the seconds hand is brighter.

Micro-adjustable clasp: In this mod the normal clasp is changed to the more modern micro-adjustable clasp. This requires changing the last links to ones with screw ends. This gives the wearer three different positions to adjust the watch thorough the day.


The 2254.50 is a great watch. The bezel of the 2254.50 is a letdown, but the size, lume and dial make up for its downfalls. The watch is simply great and works well with bracelet and even better on a Nato strap.
