A rough, brushed case carved out of stainless steel and completed by a sapphire crystal and screw down crown - no fuss, no games. A true tool watch ready for everyday wear above and below water.
This watch is comprising our Voyager GMT dial and GMT hands (both lume filled and silver polished), powered by the NH-34A automatic GMT movement made in Japan. To maximise suitability for any situation, the GMT Toolwatch is equipped with an FKM/Sailcloth hybrid strap. Utterly resistant to water and easy to clean, while the sailcloth top layer ensures a modern, but not too sporty look.
This watch is ideal for anyone who likes the durability of a diver watch, but prefers to skip the rotating bezel in favour of a sleeker, cleaner design.
