Built around the 231.13.43.22.01.001 reference, this replica Seamaster 231134 introduces a GMT complication on a black dial Aqua Terra with a leather strap instead of the more common steel bracelet. The black teak-patterned dial paired with an orange GMT hand creates the same contrast seen on other Seamaster GMT variants, but the leather strap shifts the overall character away from sporty and toward travel-dressy. Omega released this configuration specifically for buyers who wanted GMT functionality without the weight and bulk of a full steel bracelet.

Technical Overview

• Dial: black with vertical teak pattern
• Complication: GMT with independently adjustable hour hand
• Strap: brown leather with deployant clasp
• Crystal: domed sapphire with anti-reflective treatment
• Movement: automatic GMT caliber
• Date: window at 6 o’clock position
• Caseback: transparent exhibition display

The leather strap reduces the overall weight compared to the bracelet version by a noticeable margin. On long-haul flights or extended office days, that weight difference translates directly into wearing comfort.

Inside the Movement

The GMT mechanism allows the main hour hand to be set independently from the 24-hour GMT hand. Crossing time zones means pulling the crown to position two and clicking the hour hand forward or backward in one-hour jumps while the GMT hand continues tracking home time on the inner 24-hour scale. The black dial makes the orange GMT hand the most prominent element on the face, which is practical for quick glances. For a steel-bracelet alternative without the GMT function, the 42mm 231.10.42.21.03.006 offers a simpler three-hand layout in the same case family. Both sit within the broader Seamaster collection.

What Sets It Apart

The leather strap option on a GMT watch is an unusual combination in the Seamaster catalog. Most GMT references ship on steel because the travel-tool aesthetic implies a rugged build. This reference goes the opposite direction, treating the GMT as a businessman’s complication rather than an explorer’s instrument. The dark dial, warm brown leather, and functional orange accent hand create a combination that works in airport lounges and boardrooms alike. This replica Seamaster 231134 is the GMT Aqua Terra for wearers who prefer strap comfort over bracelet heft.
