The 231.10.43.22.03.001 reference, this replica Seamaster 231104 blue, adds a GMT hand to the Aqua Terra platform for travelers who need a second time zone without switching to a dedicated pilot watch. The blue dial retains the vertical teak pattern that has defined the Aqua Terra sub-family since its 2002 introduction. A bright orange GMT hand contrasts sharply against the blue background, making the second time zone instantly readable. This is one of the larger Seamaster references in the current catalog and wears noticeably different from the standard 41mm Aqua Terra models.

Technical Overview

• Dial: blue with vertical teak stripe motif
• Complication: GMT (second time zone) with independently adjustable local hour hand
• Crystal: domed sapphire with anti-reflective treatment
• Bracelet: stainless steel three-link design
• Movement: automatic GMT
• Date: displayed at 6 o’clock
• Caseback: see-through exhibition style

The GMT function works through a fourth hand that tracks a second time zone on the 24-hour scale printed on the fixed inner bezel ring. The local hour hand jumps independently in one-hour increments, so crossing time zones requires only a few clicks of the crown.

Inside the Movement

GMT movements add mechanical complexity that basic three-hand calibers do not carry. The extra gear train for the independently settable hour hand means more parts, but the trade-off is genuine travel functionality. Omega positioned this reference between the dressy Aqua Terra and the tool-focused Planet Ocean GMT, giving it a dual personality. For a direct comparison within the collection, the dark blue 220.10.41.21.03.004 drops the GMT complication entirely and focuses on a simpler three-hand layout. Both are available through the Seamaster range, but the GMT variant appeals specifically to frequent travelers.

What Sets It Apart

Size is the obvious differentiator. The larger case accommodates the GMT display without crowding the dial, and the extra wrist presence works well on arms that find 41mm too conservative. The orange GMT hand against deep blue is not just functional but adds a distinctive color accent that most Seamaster references lack entirely. This replica Seamaster 231104 blue puts that travel-ready complication and bold color pairing into a format that still reads as dressy enough for business settings.
