The first-generation Seamaster Planet Ocean pairs broad-arrow hands and an aluminium bezel with a case that wears slimmer than the later calibre 8500 generation. Introduced in 2005, it brought a tougher, more substantial feel to the Seamaster family without losing the curved lugs and clear dial that make an Omega diver so easy to enjoy.

For the restrained version, the 42mm 2201.50 has a black bezel and white dial numerals; the orange-bezel 2209.50 gives the same watch a distinctly different personality. Both use the Co-Axial calibre 2500, which underwent revisions during this generation’s production. Later examples can have the 2500D, but a production-date estimate alone isn’t enough to establish that. Bezel originality is worth attention too: a replacement aluminium insert can erase the fading and wear that give an early Planet Ocean its particular character.

What owners love

The first-generation case is noticeably slimmer than the later Planet Oceans, and the 42mm size feels more manageable on the wrist. You still get the substantial feel of a Planet Ocean without quite so much height.
The matte dial, broad-arrow hands and strong lume make it easy to read at a glance. The double-sided antireflective coating makes the crystal almost disappear in some lighting—something owners often miss when wearing other watches.
The aluminum bezel gives this generation a less glossy look than its ceramic successors. Together with the restrained dial, it feels more like a straightforward dive watch than the later, more elaborate versions.

Common Criticisms

The antireflective coating on the outside of the crystal can pick up scratches and scuffs even when the sapphire underneath is unharmed. Those marks can be surprisingly visible in certain light.
It is still a heavy watch on the bracelet, despite being slimmer than later generations. Owners who prefer lighter watches can find the weight tiring over a full day.
The original bracelet clasp lacks the convenient push-button fit adjustment found on newer Omega clasps. Getting a comfortable fit as your wrist swells can be frustrating.
