Built around a round 43.5mm titanium case measuring 17.25mm thick, this Planet Ocean GMT wears the hallmarks of serious dive-watch engineering. A screw-in crown, scratch-resistant sapphire crystal, and water resistance rated to 600m/2000ft speak to a watch designed for demanding environments, while a bi-directional rotating bezel and transparent case back add both function and visual interest.
The blue dial sits beneath the sapphire crystal with clean legibility, and the titanium bracelet — finished with a brushed surface — closes via a folding clasp with safety latch. Titanium throughout keeps weight in check without sacrificing durability, making the overall package comfortable even on extended wear.
Inside beats an automatic chronometer movement, COSC certified for precision, and equipped with a GMT complication for tracking a second time zone simultaneously. Reference 232.90.44.22.03.001 represents the Seamaster Planet Ocean lineage at its most capable.
