Mido had a bonafide hit on their hands in 2020 with Ocean Star Decompression Timer, a colorful skin diver based on the original Ocean Star divers from the 1960s. The brightly colored sectors allow divers to time decompression stops by sight, but for those of us who tend to spend most of our time topside, it was just a fun way to incorporate some color into a style of watch that sometimes veers toward the sober. The viral success of that release (it sold out quickly and seemed to dominate Instagram for a brief period of time) makes it somewhat surprising that Mido hasn?t returned to the format more frequently in the years since, but here we are with what I think many would argue feels like a natural follow up.

Importantly, the bezel maintains a minute scale, with 10 minute intervals marked off in the midst of international cities, which means you could still use this watch as a dive tool if you needed to.
