Mido Ocean Star Decompression Worldtimer 40.5 mm – Black Dial with Decompression Scale & GMT – Stainless Steel – Automatic [M026.829.17.051.00]

Bold, retro-inspired and engineered for adventure, the Mido Ocean Star Decompression Worldtimer M026.829.17.051.00 is a striking fusion of classic dive-watch heritage and modern travel functionality. Its 40.5 mm polished stainless-steel case and vintage-style “glassbox” sapphire crystal give the watch a distinctive look, echoing the dive watches of the 1960s while delivering contemporary robustness.

Beneath the crystal, the black dial is stamped with a vibrant multicolored decompression scale, a nod to the models of the past — yet now complemented by a GMT hand and 24-hour ring, allowing wearers to track a second time zone with ease. A rotating world-time bezel adorned with major city names completes its travel-ready credentials.

At the heart of the timepiece beats the Calibre 80 automatic movement, delivering an 80-hour power reserve and reliable performance. With 200 m / 20 bar water resistance, a screw-down crown, and Super-LumiNova on the hands and markers, the watch is built to handle both underwater adventures and urban journeys. Supplied with both a rubber strap (sporty dive-ready use) and a steel mesh bracelet, the Decompression Worldtimer offers versatility and style for every setting — from beaches and boats to city streets and travel itineraries.

A true collector’s piece: nostalgic in spirit, modern in execution, and perfect for those who value both function and vintage-inspired flair.
