Omega’s Seamaster Planet Ocean 600M Combines an Innovative Ceramic Compound with Titanium

Formerly dominated by stainless steel and precious metals, the watch industry has seen a rapid push in the use of two specific materials in recent years: ceramic and titanium. What makes ceramic so coveted is its scratch resistance and ability to utilize different colors without needing to employ plastic. On the other hand, titanium, for a metal especially, is extremely lightweight — nearly half the weight of its stainless steel counterparts. Rarely used in tandem, ceramic and titanium have been combined, in a sense, by Omega for a remarkable release of its Seamaster Planet Ocean 600M GMT in dark gray.

While the dive watch has hosted an array of innovative materials, this new silicon nitride ceramic (Si3N4) is among the most notable. Used on the case itself, the NAIAD LOCK caseback, and the bezel insert, the compound has never been used on this level in watchmaking and offers a lightweight yet tough upgrade to the already-robust timepiece. A typical Seamaster Planet Ocean 600M GMT is known for its use of the classic zircon ceramic material, which is actually twice as heavy as Si3N4. As for the bezel body, helium escape valve, sandblasted dial, hands, indices, and rubber strap’s buckle on this new watch, Omega has chosen to employ grade 5 titanium to cut weight and offer a nice contrast from the dark gray Si3N4.

Capable of going an incredible 600m underwater, the 45.5mm Planet Ocean is one of the most impressive divers out there, and the addition of the GMT complication — thanks to the lightweight Co-Axial Master Chronometer Caliber 8906ti movement which also uses titanium and is visible through the caseback — makes this one of the best adventure watches you can find.
