Omega Seamaster – A Quality Chronometer


Louis Brandt founded Omega in 1848 in a tiny watch business in La Chaux de Fonds, Switzerland. Omega Seamaster watches were first introduced in 1948, having a 30.10 mm movement. The watch was so exotically engineered and built that it became a fan favourite almost instantly.

Omega has been at the forefront of dive timer technology since its inception, introducing features such as unidirectional rotating bezels, helium escape valves, luminescent hour markers, and hands to their watches long before other brands caught on. In fact, many experts consider Omega’s Seamasters some of the best diving watches available today.

Omega Seamaster is known as the best all-rounder chronometer. Chronometers are timepieces placed in vacuum chambers so the movement is not disturbed by the pressure and humidity. Omega watches are considered the best all-rounders in the market and many characteristics contribute to this fame of their line.

In the olden days, casual watches were susceptible to water. You could not wear a watch and play with water, and it cost a lot of people huge amounts. The reason behind this was the branded watches were and are expensive. And buying these watches only to lose them to a few droplets of water was idiotic. Omega then came up with the idea of a water-resistant watch line, the Seamaster.

Omega embarked on a design journey to create the world’s first divers’ watch. This quest led to the launch of the Seamaster in 1948. The development of this iconic timepiece was driven by two key factors: performance and durability.

The original Seamaster was designed as a precision instrument that could withstand even the harshest environments and rigorous use underwater. Seventy years later, it remains an internationally recognized symbol of elegance and toughness – perfect for both professional divers and everyday wearers alike.

Ten years later, Rolex came with their variant of underwater functional watches. So Seamaster decided to re-enter the market as not only under-water watches but also as dress watches. The watches were redesigned to fulfil the standards of a dress watch and stormed the market once again.

Different watches of Omega Seamaster

Omega Seamaster has a lot of variants. These vary depending upon different features, the material used, and the spectra of their use. These variants are:

Professional diver

They are available in both male and female styles, in automatic and quartz movements. Two different dial styles are available in the men’s variant, the skeleton hand and the GMT style.

Professional chronographs

As the name suggests, they are highly mechanical with only automatic movements. Available in titanium, these are heavy watches with large dials and are only available for men.

Professional GMT

These were the modified versions of the Omega Seamaster professional diver watches. The modifications included an extra GMT hand towards the bezel. A titanium diver was added. It is available in men’s style only, and the movement is automatic.

Aqua Terra

These watches are the most different in the Seamaster range. They are available in both men’s and women’s styles. The movements are either coaxial or quartz.


These are the further modified versions of the Aqua Terra. They were launched as a tribute to the original watch which influenced the aqua terra variant. It features a coaxial movement only.

Movement of the Seamaster

All of the female style Seamasters are available in quartz movement only, however, the movement in men’s watches vary in all the models. Some offer both movements and some are confined to only one.


There is no question that Omega Seamaster watches are among the most accurate timepieces in the world. For many years, they have been favoured by professional divers for their precision and durability. In addition to being watertight and rust-resistant, Omega Seamasters also keep extraordinarily precise time.

The history of the Omega Seamaster watch can be traced all the way back to 1932 when it was first released as a waterproof wristwatch specifically designed for divers. It wasn’t until 1948, however, that Omega began producing its famous “Seamaster” model – which has remained virtually unchanged ever since. The key feature that sets this watch apart from others is its co-axial escapement movement (developed by George Daniels), which significantly reduces friction and prolongs wearability. Today’s modern versions of the OMEGA Seamaster boast an impressive chronometric performance with a COSC certification.

As these watches aim to be mechanical, they are certified as chronometers. The quartz models are not certified, but the automatic models are validated with a variation of -4 to +6 seconds per day time measurement which reflects high performance.
