OMEGA 54's / Seamaster / Cal.344

OMEGA's signature collection, the Seamaster, was launched in 1948 .

Its origins lie in the waterproof watches supplied to the British military during World War II, and this model sublimates the reliable technology cultivated through military use into a more elegant form suitable for everyday use.

When the Seamaster was first released, it was introduced as "the world's first automatic watch with a waterproof case structure."

The concept is "in the city, by the sea, in the suburbs."

As a waterproof dress watch that can be used in any situation, it has gained the trust of many people and continues to be loved as a long-selling collection that has continued to evolve since its release.

The Seamaster features a silver dial that retains a metallic texture and striking details unique to the 1950s .

The dial is a calm silver color.
The surface does not reflect light as strongly as a sunray finish, but has a dull metallic luster that changes its appearance gently depending on the angle. The texture, which is typical of the Seamaster of the 1950s and does not have excessive decoration, is impressive.

The index uses a three-dimensional wedge shape.
The sharp shape that extends towards the tip gives a moderate sense of tension to the simple dial composition.

It doesn't stand out too much and fits naturally into the overall balance.

The hands are slender and elegant dolphin hands.
The silver-toned dial and texture match, ensuring visibility without disrupting the overall calm impression.

The case is a round, moderately rounded stainless steel case.
The balance between straight lines and curves is beautiful, and the watch exudes the honest and elegant appearance that is typical of Omega from the 1950s .

Although the design is simple and free of excessive decoration, the sharp edges and the gentle curves clearly convey the careful attention to craftsmanship that was required at the time.

The movement is equipped with the automatic Cal. 344 .

This is a half-rotor automatic movement that was adopted in the early 1950s .

The design does not completely cover the inside of the case, allowing for efficient winding while keeping the entire case thin.
Although it is an automatic watch, it is designed with comfort in mind, giving it the practicality you would expect from a Seamaster of the time.

Case size: height: 42.1mm , width: 37.3mm , thickness: 9.7mm , weight: 70g .

The subdued silver-toned dial and understated case design blend naturally with any outfit.
It goes well with neat outfits like shirts and jackets, as well as softer textures like knitwear and wool, making it a piece that can be easily incorporated into your everyday life.

The case is in good condition with no noticeable scratches.
There are some changes to the dial due to aging, but this does not affect visibility.
The movement is running smoothly and can be used without any problems.

It is fitted with a genuine Omega rice bracelet.
