Details & Specifications
Description:
The Tudor Iconaut GMT Chronograph (reference 20400) is a bold and distinctive expression of Tudor's mid-2000s identity, launched in 2008 as the brand's second take on a GMT-equipped watch. Crafted from stainless steel, its curvaceous cushion-style case offers a commanding, substantial wrist presence. The black dial, featuring an outer minute track with applied lumed pips, a 30-minute register at 12 o'clock, a 12-hour register at 6 o'clock, and continuous seconds at 9 o'clock with red accents, is powered by the dependable calibre 7754 automatic chronograph movement, offering robust accuracy alongside true dual time zone functionality via a red GMT hand with a white triangle tip.
With its broad sloping fixed 24-hour bezel deeply etched in black lacquer, flat sapphire crystal, and screw-down crown and case-back, this Iconaut bridges Tudor's tool-watch roots with unmistakably individual design. Fitted on a stainless steel bracelet with a folding buckle, this watch remains a distinctive classic—an acquired taste that rewards those drawn to bold, unconventional watch design.
This piece presents in excellent condition.
