The T9 was designed for affordability without compromising Torgoen's quality and design. It has a Swiss GMT movement manufactured by Ronda that allows to set the GMT hand to a different time zone, which in the case of a professional pilot would be the Greenwich Mean Time or GMT. This ability makes it a perfect fit for the world traveler or for anyone that has a friend or a family member in a different time zone."The case is made from high grade solid stainless steel with screw-down stainless-steel curved back. The T9 has a high quality mineral crystal and vintage Italian leather was used for the straps. Our quality control team performs various wear-and-tear tests that include stressing the straps and spring-bars, submitting 100% of the watches to 10 ATM (100 meters) pressure in water tanks.
