Yema Superman CMM.10 Bronze: French Caliber, Sub-$2K Diver

Bronze dive watches are nothing new. But a bronze diver with a true French manufacture movement, a 70-hour power reserve, and chronometer-grade performance for under $2,000? That’s something else entirely. Yema just dropped three new permanent additions to its iconic Superman collection, and they’ve hit a sweet spot. The new Superman Bronze CMM.10 series combines the brand’s signature vintage diver DNA with its impressive new in-house automatic caliber. This isn’t just a cosmetic update; it’s a serious technical evolution. The result is a trio of watches that look the part and have the specs to back it up. These aren't limited editions, but permanent models designed for real use. Let’s get into the weeds and see what makes them tick. We’ll look at the shared platform before breaking down each of the three distinct dial colors.

The Engine: Yema's Calibre Manufacture Morteau 10

The heart of these watches is the real story here. The CMM.10 is Yema’s new-generation manufacture movement, designed and assembled in Morteau, France. This isn’t an off-the-shelf caliber with a custom rotor; it’s the genuine article. It runs at a modern 28,800 A/h (4Hz) for a smooth sweep. More importantly, it boasts a 70-hour power reserve. That means you can put it down on Friday night and it’ll still be running Monday morning—a practical feature that many bigger brands still don't offer at this price. Yema also regulates the CMM.10 to a chronometric precision of -3/+5 seconds per day. That’s well within COSC territory. You can see the movement through a sapphire display caseback, a nice touch for a 300-meter diver.

The Bronze Case and Superman DNA

The case material is, of course, a key part of the appeal. Bronze develops a unique patina over time based on your environment and wear habits. No two watches will look the same after a few years, making each one personal. Yema chose a perfect size at 39mm in diameter and about 11mm thick. These are fantastic, wearable dimensions that should suit a wide range of wrists. It’s a welcome departure from the oversized bronze pieces we often see. The watch is topped with a 2.2mm double-domed sapphire crystal, giving it a great vintage distortion at the edges. True to its professional specs, it features a screw-down crown and a 300-meter water resistance rating. That’s more than enough for any recreational or professional diving.

The White Dial: Yema Superman Bronze CMM.10 Ref. 17.26.10.37.ZN.U7

First up is the white dial variant. This one offers a clean, high-contrast look that feels both vintage and contemporary. The glossy white lacquer serves as a perfect backdrop for the gilt-treated hands and applied indices. The warmth of the gold-tone accents against the stark white is fantastic. It prevents the watch from feeling sterile and ties it directly to the warm tones of the bronze case. As the case patinates, this contrast will only get more interesting. This is probably the most versatile of the trio. It can easily dress up or down, pairing as well with a t-shirt as it does with a casual blazer. The integrated FKM rubber strap is comfortable and durable for daily wear.

The Brown Dial: Yema Superman Bronze CMM.10 Ref. 17.26.10.38.ZN.U8

The brown dial is the quintessential choice for a bronze watch. The deep, glossy brown lacquer has an almost chocolatey appearance that harmonizes perfectly with the case material. This is the warmest and most overtly vintage-inspired model of the bunch. The gilt hands and markers seem to melt into the dial, creating a rich, cohesive aesthetic. It evokes the feeling of a tropical dial that has aged naturally over decades. Paired with the bronze case, it’s a home run for anyone who loves that 1970s diver vibe. This reference feels like the most natural pairing for the bronze. It leans heavily into the warm, earthy tones of the metal. If you want a watch that fully embraces the patina lifestyle, this is the one.
