The Classics Index GMT provides an alternate time zone reference at a glance. The GMT hand with it’s unmistakable red triangle, makes one rotation every 24- hours and can be used to read off a second time zone on the 24 hour scale placed beneath the hour markers. In addition to the GMT, all the watches feature hours, minutes, seconds and date. These reliable functions adjustable through the single crown are powered by the FC-350 automatic movement, which has a power reserve of 38-hour and 26 jewels. You can observe the precision movement in action through the sapphire crystal case back, which is water resistant to 50 meters.

The Classics Index GMT is available in four different variants. One combines a steel case with an intense black dial on a classical metal bracelet. The stainless steel models, with a silver dial are paired either with a black leather strap or a metal bracelet to match the case. The last distinguishes itself with a rose gold plated case and hand applied rose gold plated indexes, combined with an elegant brown leather strap.
