Mido puts a decompression table and 24 cities on one Ocean Star dial, for CHF 1,270

Mido's Ocean Star Decompression Worldtimer puts a decompression scale in the centre of the dial and twenty-four cities around the outside, at CHF 1,270 with a mesh bracelet and a rubber strap both in the box.

Decompression tables live on dive watches. World time rings live on travel watches. Nobody else is selling the two together, and you can sort of see why. Mido has printed both onto a single 40.5mm dial anyway. Reference M026.829.17.041.00, and it went up on Mido's own site this week.

Colour is the first thing you get, well before the time. Concentric rings in pink, yellow, blue and green sit right in the middle of the dial, and that's not decoration, it's the decompression scale. Look at it for a minute and you genuinely can't tell whether you're looking at a dive watch or a beach towel.

Cities on the bezel, a dive table in the middle

The bezel runs the usual world time roll call, New York round through London, Geneva, Moscow, Dubai, Bangkok, Tokyo, Sydney and Auckland and back to Los Angeles, read against a 24-hour ring at the edge of the dial. The decompression graphic sits inside all of it, taking up most of the face and supplying the longer half of the watch's name.

It's busy. You can't call a dial with this much printing on it restrained, and Mido hasn't tried to. Whether you can live with it comes down to whether that centre reads to you as dive history or as clutter. I read it as history, and I'd wear it.

Eighty hours out of the Caliber 80

Inside is Mido's Caliber 80, the automatic the whole family is named after, running to something like 80 hours of reserve. That reserve is the quiet reason to buy a Mido. Almost nothing else near the money offers it.

The case is 316L stainless steel with a screw-down crown, good for 20 bar, which is 200 metres. The crystal is sapphire, with a single anti-reflective coating on the underside.

Mesh or rubber, and you get both

It's a special edition, and the extra is a second strap. There's a steel mesh bracelet and a blue textured rubber strap, and swapping between them genuinely gives you two different watches. On the mesh it's a 1960s tool watch. On the rubber it's a modern one. Two straps is more than most brands are prepared to put behind the word special.

CHF 1,270, and no local listing

Mido lists it at CHF 1,270 on its international site, which is less than plenty of dress watches that do neither of the things this one does. Mido has been quietly good value for years and this is that same value, just louder about it.

No Australian number, though. The reference isn't in the local catalogue, and Mido's Australian site bounces it straight back to the homepage.
