Mido Caliber 80 GMT

The Mido Caliber 80 GMT is based on the ETA C07.661, a Powermatic 80 movement with an additional 24-hour GMT hand. Functions as a 'true GMT' or 'traveller's GMT' where the local time hour hand can be independently adjusted in 1-hour increments while the GMT hand tracks home time. Note: Date change requires advancing local time past midnight (no quick-date function). The 80-hour power reserve is achieved through a longer mainspring barrel operating at 21,600 vph. Used in Ocean Star GMT models.
