TAG Heuer Aquaracer Professional 300 GMT WBP2010.BA0632

About This Watch

The TAG Heuer Aquaracer Professional 300 GMT WBP2010.BA0632 adds a coveted travel complication to the brand's flagship dive watch, powered by the new TH20 caliber with an independently adjustable GMT hand. This movement allows the wearer to track a second time zone on the 24-hour scale bezel while maintaining accurate local time — essential for travelers and professionals working across multiple time zones. The blue and black bi-color ceramic bezel insert distinguishes day hours from night hours in the second time zone, a functional and aesthetic feature that adds visual complexity to the Aquaracer's clean design language. The TH20 caliber delivers an impressive 70-hour power reserve, nearly doubling the Calibre 5 used in standard Aquaracers, ensuring reliability even after a weekend off the wrist. At 43mm with 300 meters of water resistance, the GMT retains all of the Professional 300's dive watch credentials — unidirectional bezel, diving extension clasp, luminous markers — while adding the travel functionality that makes it a true daily-wear tool watch. The blue dial maintains the signature horizontal ridge texture, while the GMT hand adds a fourth hand to the dial in a contrasting color for clear differentiation. The Aquaracer GMT fills a gap in TAG Heuer's lineup that enthusiasts had long requested, offering genuine dual-time-zone capability at a price that significantly undercuts comparable offerings from Rolex, Omega, and Tudor.
