Yema has spent the last few years turning itself from a value-focused French brand into one that builds its own movements, and the Superman is where most of that work shows up. The latest additions are three new versions of the Superman Bronze, all fitted with the in-house CMM.10 and all trading on the same idea: a manufacture automatic in a patina-friendly case, for less than most Swiss divers with outsourced calibres. Monochrome published a first look on 6 August 2026, with the full specifications.
A bronze case that ages
The case measures 39mm across and 10.95mm thick, with a lug-to-lug of 48mm, which keeps it wearable on smaller wrists. It is rated to 300 metres, with a screw-down crown, a 2.2mm double-domed sapphire crystal and Yema's signature bezel lock, the small catch that stops the timing bezel from turning by accident. Both the case and the unidirectional bezel are bronze, the bezel given a radial brushing that catches light differently from the vertically brushed case.
Being bronze, it will not stay the way it looks in the press images. The alloy develops its own patina depending on how it is worn and where, so two examples of the same reference will diverge over time. That is the point of a bronze watch, and Yema leans into it rather than trying to seal the metal away.
The dials are the update
The mechanical package is carried over from the existing Superman CMM.10, so the news here is really the dials. All three are glossy lacquered, in brown, green or white, with applied gilt Yema logos and hour markers and gilt-coated diamond-cut hands. The lume is Grade A Super-LumiNova, which reads a warm beige in daylight and glows green in the dark. The markers have been redesigned to sit slightly more upright, giving the dial a marginally more modern look than the printed geometric indices of the earlier black and blue editions, which Yema still sells.
Each colour comes on an integrated FKM Tropic-style rubber strap in a matching shade, closed with a brushed bronze pin buckle, on 19mm lugs. The references are 17.26.10.38.ZN.U8 for brown, 17.26.10.34.ZN.U4 for green and 17.26.10.37.ZN.U7 for white.
Made in Morteau
The reason to pay attention to a EUR 1,790 diver is under the caseback. The CMM.10, or Calibre Manufacture Morteau 10, is developed, assembled and regulated at Yema's workshops in Morteau, in the French Jura. It runs at 28,800vph and delivers a 70-hour power reserve from a large single barrel, and Yema rates its accuracy at minus 3 to plus 5 seconds a day, tighter than chronometer specification. The brand also claims improved resistance to shocks and magnetism, and the movement's symmetrical mainplate is the base for its current generation of in-house calibres.
None of that makes the Superman Bronze a luxury object, and it is not trying to be one. What it offers is a French-made automatic movement, a proper 300-metre bronze case and a permanent place in the range rather than a limited run. At the price, that combination is unusual, and it is the reason the Superman keeps turning up on shortlists for a first serious dive watch.
