Mido - 2020s Ocean Star Decompression Worldtimer M026.829.17.051.00

WHAT WE LOVE:

Few watches at this price point pack as much onto the dial as the Mido Ocean Star Decompression Worldtimer. The design draws directly from Mido's own archive. The original Ocean Star Decompression Timer of the 1960s was one of the first dive watches to incorporate a decompression reference scale on the dial itself — a practical tool for divers planning staged ascents at specific depths.

The modern Worldtimer revives that heritage and adds a GMT complication to it, creating a dial that simultaneously references the dive watch tradition and addresses the needs of a contemporary traveller. The outermost ring of the bezel carries a full 24-hour world city scale, allowing the wearer to read a second time zone at a glance against the red GMT hand. Inside that, the dial carries the decompression timing scale. The block-shaped hour markers and applied indices provide a clear anchor for conventional time reading.

The black version is very legible and the most striking of the Decompression Worldtimer configurations. Against the dark base, the multi-colour scale markings and the red GMT hand read with the kind of immediate clarity that vintage dive instruments always prioritised above decoration. The starfish engraved in relief on the screw-down caseback is a quiet nod to the Ocean Star heritage, and one of those details that rewards turning the watch over in the hand.

WHAT’S INSIDE:

The M026.829.17.051.00 is powered by the Mido Calibre C07.661 — Mido's designation for the ETA Powermatic 80, featuring an anti-magnetic Nivachron™ balance spring and delivering an 80-hour power reserve across 21 jewels at 21,600 vibrations per hour. The GMT complication is driven by an additional 24-hour hand that completes one full revolution per day, readable against the world city bezel scale for instant second time zone identification.
