It's safe to say we've been nursing a healthy obsession with MIDO's revival of its 1960s Ocean Star Decompression Timer since 2020. Maybe it's the thrill of finding a vintage-inspired dive watch that nails all the tiny details. Maybe it's the colorful decompression scale that captures the imagination of watch newbies and seasoned collectors alike. Whatever the case may be, we are happy to introduce you to MIDO's latest expansion of its heritage dive watch collection: the Ocean Star Decompression Worldtimer, now with an additional GMT function recreated in both the original "rainbow" as well as a new vivid colorway.

Admittedly, by using a multicoloured scale to display decompression times, none of the predecessors have conformed to a particularly low-key look. But this new piece ups the ante by adding GMT functionality. Once again, this latest piece displays decompression times to a depth of 6 metres using circles of yellow, green, pink and blue on the navy dial version or a variety of yellow and orange hues on the black dial version. But now the bezel is almost as frenetic, providing two extra rings of info in the form of the names of world cities marked in silver.

Essentially, the 40.5mm stainless-steel case encircles nine concentric rings of information for the eye to take in. The overall effect is full-on and weirdly hypnotic. The tonal colours of the black dial version bring the overall psychedelia down a notch or two to manageable levels. But the blue dial one is utterly bonkers.

MIDO's Caliber 80.661 movement provides automatic winding, a Nivachron balance spring, a whopping 80 hours of power reserve, and, in our opinion, represents one of the best mechanical devices available at this price point. In typical dive watch fashion, the Ocean Star Decompression Worldtimer sports water resistance up to 200 meters, as well as glowing Super-LumiNova in the hands and indices. The closed steel caseback is emblazoned with the signature starfish engraving that has been featured across the Ocean Star line since the 1960s.

Both models of the Decompression Worldtimer ship with an interchangeable, tropical rubber strap as an homage to the original, along with a stainless steel mesh bracelet that's every bit as 1960s as the rubber strap.

You don't have to be a diver to bask in the mystique of one of the most fascinating dive watches ever produced, and with the added GMT function, the new MIDO Ocean Star Decompression Worldtimer makes the perfect travel companion wherever life takes you.

My first impressions are of a watch that’s an awful lot of fun. There will inevitably be some who talk of diminishing returns with the new model and how this GMT addition perhaps takes things one step too far. For me, however, Mido’s Decompression Timer was never a watch about elegant restraint. This new Worldtimer version has a slightly mad glint in its eye and is embracing the chaos with a smile.
