Seamaster is one of the most iconic collections of watches around. Created by Swiss watchmaking royalty Omega, there have been various models found in the numerous collections that have been released under the Seamaster range since it began in 1948.

In 2005, Omega wanted to add something new to the Seamaster collection that would serve as the perfect homage to the original timepieces that made the collection so iconic. They released the Planet Ocean collection, which has produced some truly spectacular models in a relatively short time.

One such model is the Omega Seamaster Planet Ocean 600m Co-Axial Chronograph 45.5mm, with the titanium and rubber strap version serving as the perfect maritime themed watch. Featuring a round titanium case that is a great size at 45.5mm, this model captures the beauty of the ocean through the deep blue colours found on the dial, strap, and bezel of the watch.

The blue dial has a scratch-resistant sapphire crystal protecting while the bezel has unidirectional rotations and features the same blue hues as the dial and rubber strap. It uses a blue ceramic for the bezel which has polished and brushed ribbed edges.

There are liquid metal numbers and indexes, which is an alloy that has three times the strength of steel and can easily bond with ceramic, making it a fine choice giving the ceramic bezel.

One the dial the index hour markers have applied polished steel and have a blue luminescent fill. This is similar to the hour and seconds hands which made from polished steel and also have a blue luminescent fill. The minute hand changes this slightly by having a green luminescent fill, which is also the case for the dot marker found at the 12 o’clock position of the rotating bezel.

The chronograph functioning is displayed on two sub-dials. One is for the minute and hour counters and can be found at the 3 o’clock position, whilst the other is used for the continuous seconds counter and is situated at the 9 o’clock position. There is also a date window display at the 6 o’clock position.

The hour hand consists of orange aluminium with the minute hand being made from polished steel – both of which contain a luminescent fill.

The Omega Planet Ocean 600m Co-Axial Chronograph 45.5mm wouldn’t truly be part of the Seamaster family if it wasn’t water resistant. Of course this model is and to a really impressive 600 meters/ 2000 feet. Whenever in use, there is a helium escapement valve can be found at the 10 o’clock around the edging of the case.

As for the calibre for the Planet Ocean 600m Co-Axial Chronograph 45.5mm, it uses the Omega automatic calibre 9300. This movement produces 28,800 vph and there are a total of 54 jewels within. The twin barrels mounted in this series of calibre allows for a massive power reserve of 60 hours.

This calibre also contains Omega’s Si 14 silicon balance spring. This helps to create a very shock-resistant movement that can handle many disturbances that would otherwise affect the functioning of the calibre, which in turn enhances the general performance of the watch.

Another key component of the movement is the presence of the co-axial escapement. This has been developed to allow for more precision in the movement, as well as helping to improve how stable and durable it is.

Both the co-axial and Si 14 have helped to guarantee not just the stability of the movement, but also its general reliability –you can be sure you won’t be let down by the performance of this calibre.

With a transparent case back, you can view the inner workings of the movement as well, including the column wheel, rotor, and bridges.
