For the international traveler, this GMT offers the convenience of being able to change time zones without interrupting the one second-per-day precision of the Spring Drive movement. The rotating bezel has a 24-hour scale, which, when used in conjunction with the GMT hand and the 24-hour ring on the dial, allows the watch to indicate three different time zones at the same time, making it perfect for international travel. The sapphire bezel provides a strong sense of depth to the look of the watch, and the large hands and indexes are filled generously with LumiBrite—a proprietary luminous compound—which is also featured on the bezel. Additionally, the high-quality sapphire glass on the surface of the bezel provides extra resilience against scratches. The harmonious combination of the jet-black dial and the red GMT hand signify the sparks of the Kiribi ceremony, a sign of good luck to those who explore the world.
