Omega Planet Ocean 600m Co-Axial Master Chronometer GMT Review
Omega has been adding more of the deep black editions ever since the advent and success of the Speedmaster Dark Side of The Moon series. The appeal of this more modern design coupled with feature-rich watches allows Omega to push their way to the forefront of the market and offer watches that are both highly advanced in terms of their mechanics but also up-to-the-minute and current in terms of their design.
The Seamaster Planet Ocean 600m Co-Axial Master Chronometer GMT was released after Basel 2016 and is a great example when Omega creates a watch that can serve multiple purposes all the while looking great.
There is no shortage of available diving watches and definitely, no shortage of GMT watches out there ...even ones made by Omega. However, Omega decided to make something that would look and work great on your wrist when dry or soaking wet and offer a little more for your money to people considering the purchase of watches with similar features from their competitors.
Key Features
- The screwed-down ceramic case back called the new Naiad Lock system
- Transparent case back is water-resistant up to 600m and antimagnetic to 1.5 tesla / 15,000 gauss
- Master Chronometer and COSC chronometer designations (discussed in detail below)
- Date window at the 3 o'clock position
- GMT complication which provides the time in an additional time zone
- Excellent luminescence for maximum visibility in poor light conditions
Mechanical Pedigree
Master Chronometer is a designation that has been making its way into many Omega watches over the last few years. The term means that Omega has made several steps in order to maximize the accuracy and reliability of the caliber. A COSC certification implies that the watch has a mechanical accuracy of -4/+6 seconds per day.
Once the movement receives a COSC certification, it then goes on to another lab, this time at the Swiss Federal Institute of Metrology (known as METAS) and after further testing in the areas of water resistance, magnetic resistance, and exceptional performance and reliability, it receives the "MASTER CHRONOMETER" designation. A caliber that is a Master Chronometer has to achieve a minimum accuracy score of -0/+5 seconds per day. For a more detailed report on METAS testing for the Master Chronometer, please read our article that discusses it in detail.
Caliber 8906 Automatic Movement
The mechanical movement used in this watch is the Omega 8906 which has the following features:
- In-house caliber (made by Omega)
- COSC Chronometer Certification
- METAS Chronometer certification for its performance
- Resonates at 25'200 VPH / beats per hour / 3.5Hz
- Co-Axial escapement requires less frequent servicing
- Anti-magnetic movement which uses Omega's Si14 silicon balance spring which is also highly shock resistant enhancing the watch's reliability
- Arabesque wave design finish on the bridges and rotor
- 60-hour power reserve
Case Features
- The ceramic case that is both brushed and polished in certain areas in order to simulate the look of metal while offering the scratch resistance of ceramic
- Most watches that are non-magnetic have an antimagnetic plate protecting from the movement and therefore don't offer a transparent case back. This watch, however, has a movement which itself which can resist magnetic fields up to 15,000 gauss. This allows for a window to see the beauty of the movement
- The Deep Black case has a very similar look to the Speedmaster Dark-Side-Of-The-Moon cases
- The slightly domed scratch-resistant sapphire crystal has an anti-reflective coating on both sides
- 5 mm case size which thanks to its design doesn't look oversized when worn on the wrist
- Vulcanized rubber bezel at the 15-minute scale zone
- Helium escape valve at the 10 o'clock position
Dial Specifications
- Matte black ceramic dial engraved with Zr02 (zirconium oxide) above the 6 o'clock position
- White gold hour, minutes, and seconds hands which use a brushed finish which have a green-hued luminescent emission
- White gold index hour markers with luminous fill that emits a blue-hued luminescence
- Arabic numerals in Blue for the 6,9, and 12 o'clock hour indices
- Blue arrow-shaped GMT hand behind the hour and minute hands to match the blue case accents has luminescent tips
Strap Options
The strap that comes with this watch is made of deep black rubber with a weave texture and blue stitching to match the blue accents on the case. The rubber watchband closes by way of a push-button deployant buckle. Omega also manufactures NATO straps which can allow you to create all sorts of looks for your watch. These are add-ons that can usually be purchased at Omega's boutiques.
Style Options
In addition to this stunning blue style which has blue accents on the case, blue stitching on the rubber strap, there are several other styles that come with a rubber strap. There is also a higher-end version with 18kt Sedna (rose gold) accents and a leather strap.
