At 46mm, this replica Seamaster 215924 46mm commands serious wrist presence without crossing into unwearable territory. The 215.92.46.22.01.002 reference is a Planet Ocean 600M with GMT functionality, built for travelers who need a second time zone displayed on a rotating 24-hour bezel. Omega positions this reference as the oversized diver-GMT within the Seamaster family, and the dark ceramic case material keeps the visual weight lower than the dimensions might suggest.

The all-ceramic construction means the case surface resists micro-scratches that would show immediately on polished steel. The matte black finish absorbs light rather than reflecting it, giving the watch a stealth-tool aesthetic that pairs well with technical outerwear and utilitarian wardrobes.

Design & Finishing

Ceramic cases require different manufacturing processes than metal ones. Each case is milled from a single ceramic block, then polished and brushed to create contrasting surfaces. The GMT bezel uses a contrasting color scheme for day and night hours, making the second time zone readable at a glance. Compared to the steel Planet Ocean references, this ceramic version trades the traditional polished-and-brushed metal look for a more monochromatic, modern appearance.

On the Wrist

Despite measuring 46mm across, the ceramic construction is noticeably lighter than an equivalent steel case. The rubber strap with its deployant buckle conforms to the wrist quickly and handles moisture without degradation. The 600M water resistance is more than most divers will ever test, but the specification signals serious engineering throughout the build. For wrists 18cm and above this reference fills the space confidently without overhang. This replica Seamaster 215924 46mm delivers a ceramic-GMT combination that very few dive watches in this size category can match.
