Ocean Star GMT M026.829.18.041.00
MIDO is enriching its Ocean Star diving watches collection with a version equipped with the highly practical GMT function. It clearly displays the time in two different time zones: home time and local time. On the back of the sporty Swiss watch - fitted with the Caliber 80 automatic movement , which offers a power reserve of up to 80 hours - MIDO has engraved the time-zone indications. The extremely easy-to-use GMT function offers twice as much freedom for those who are either by the ocean or on an adrenalin-fuelled adventure.
