The Omega Seamaster range has long been regarded as one of the finest around. Perhaps amongst the most famous of water resistant chronometers, there have been many timeless pieces that have come from this iconic range since its first release back in 1948.
In 2005 Omega launched their modern homage to their classic line by introducing the Seamaster Planet Ocean line. The Omega Plant Ocean 600m Co-Axial Chronograph is a prime example of the masterful craftsmanship that has created a modern piece that has hallmarks of the iconic Seamaster models of the past.
The round case measures in at 45.5mm and is of course made from stainless steel, like any good Seamaster model should be. This is matched by the stainless steel band and buckle that features a nice clean brushed finish, while the buckle is secured with a push butting folding clasp.
The dial itself is a crisp matte black colour and the crystal is made with an anti-reflective and scratch resistant sapphire, which is slightly domed. The black stainless steel bezel is unidirectional rotating with a polished and brushed ribbed edge with a grey ceramic fill. All of the numbers on the bezel, the indexes and inner rim are all made from satin finished steel.
The index hour markers have applied polished steel that feature a blue luminescent fill, as does the steel hour and seconds hands. The minute hand however has a green luminescent fill along with the 12o’clock dot of the rotating bezel, offering a nice contrast.
Being a chronograph, the main feature of the Planet Ocean 600m Co-Axial Chronograph is of course the stopwatch function.
There is a large central second’s hand counter while the minute are and hour counters are combined into a single sub-dial, which is positioned at 3 o’clock. Here, the hour hand is a nice orange colour that stands out and is made from aluminium and the minute hand is a stainless steel – both of which also have a luminescent fill.
At the 9 o’clock position you will find the seconds sub-dial which operates with a small stainless steel hand that runs continuously, while at the 6 o’clock hand there is a display window showing the date.
The Omega Seamaster Planet Ocean 600m Co-Axial Chronograph is of course water resistant and can reach a depth of 600 meters/2000 feet. There is also a helium escape valve which is situated on the edging of the case where the 10 o’clock hand is positioned.
This model used the Omega calibre 9300 which features the ‘Si 14’ silicone balance spring specially designed by Omega. This allows for some truly impressive resistance against shocks and other disturbances that could damage a lower quality watch, helping to improve the overall performance of the chronometer.
Another contributor to the high quality performance of this movement is the Co-Axial Escapement. This helps to provide a more stable and durable movement, as well as helping to improve its precision. With less friction there is a reduced need for lubrication as well, which will allow for longer periods of time in-between each service.
Together with the Si 14 balance spring, the Co-Axial Escapement has ensured a much more reliable and stable calibre.
There are a total of 28,800 vph from the movement which has 54 jewels and a very respectable 60 hour power reserved, thanks in no part to the twin barrels that are mounted within this series of calibres.
The movement is visible through the case back which is fully transparent, allowing a clear view of the inner workings, including the column-wheel chronograph, the rotor and bridges – which have been adorned with an arabesque wave design finish.
A truly magnificent model, the Omega Seamaster Planet Ocean 600m Co-Axial Chronograph remains one of the most sough-after models of the modern Seamaster range.
