The Mido Ocean Star GMT exists for people whose lives straddle two time zones, whether that means a partner overseas, colleagues in another office or a trip that has not quite worn off. It takes Mido’s 44mm Ocean Star diver and adds an independent 24-hour hand, so home time and local time live on one dial.

The dark blue dial is framed by a blue ceramic bezel insert with a dive scale, and the red GMT hand with its triangular tip reads against a 24-hour ring split into day and night tones. Under the hood is Mido’s Caliber 80 in GMT form, based on the ETA C07.661, running at 21,600 vibrations per hour with an 80-hour power reserve. Adjusting it is easy: the local hour hand jumps independently, so you can change time zones without stopping the watch. The screw-down back is engraved with the world’s time zones, a nice reminder of what the watch is for.

The steel bracelet mixes brushed outer links with polished centers and closes with a folding clasp that includes a diving extension.
