Released for the 80th anniversary of the Ocean Star, the Mido Ocean Star GMT Special Edition shrinks Mido’s travel diver to a very wearable 40.5mm and dresses it in vintage-tinged blue. If the 44mm GMT always felt like a little too much watch, this is the one to look at.

The blue dial introduces shark-tooth shaped hour markers, a first for Mido, along with dauphine hands and generous Super-LumiNova. Around it, a fluted bezel with a blue aluminum insert is graduated over 24 hours, so the extra hand can track a second time zone in classic GMT fashion. Inside is Mido’s Caliber 80 in GMT configuration, based on the ETA C07.661, with a Nivachron balance spring and up to 80 hours of autonomy. The screw-down back is engraved with time-zone indications and a sea star, and the screw-down crown keeps the case water-resistant to 200 meters.

It comes on a multi-row steel bracelet with push-button deployant clasp and dive extension, and Mido adds a blue NATO-style strap so you can switch to something lighter on the road.
