YEMA lists a 70-hour power reserve, 10 BAR water resistance and a 200-piece production run. The available evidence supports a specification-led assessment, not a hands-on verdict: fit, finishing, legibility and real-world performance have not been independently evaluated here.
What is the Wristmaster Slim CMM.20 Limited Edition?
This review concerns the specific 76.24.06.SN.M reference, not other Wristmaster Slim watches that use the CMM.20 or CMM.29 movements. YEMA identifies this reference as a 200-piece limited edition. Its official US listing showed a price of $2,449 and marked it sold out; both price and availability may change. See YEMA’s product listing for current information.
The central proposition is a relatively slim, integrated-steel sports watch with a manufacturer-developed automatic micro-rotor caliber. That combination is appealing on paper, but the product specifications cannot establish how the watch feels on the wrist or whether its execution merits the asking price.

How the micro-rotor changes the proposition
The CMM.20’s micro-rotor is the defining technical feature. YEMA describes it as an automatic caliber with a ball-bearing rotor and a stated 70-hour reserve. A micro-rotor is integrated into the movement rather than mounted as a full-size rotor over it; the design can help keep a movement—and potentially the watch—slimmer. Here, YEMA lists the complete watch at 9.00 mm thick.
The dimension is promising for an integrated-bracelet watch, but the number alone does not tell you how it wears. Case shape, bracelet articulation and wrist size all affect perceived thickness and comfort, and those are matters for direct inspection. Nor does the micro-rotor designation by itself prove superior accuracy or value. YEMA’s stated rate is -3/+7 seconds per day; no independent timing data for this reference is established.

What the design and bracelet specifications do—and do not—tell you
YEMA lists a hand-brushed PVD finish on the 316L steel case and integrated bracelet, a hand-brushed dial, faceted applied markers and hands, and luminous material it identifies as Grade A Super-LumiNova. Together these details describe a deliberately finished, integrated design. They do not establish the quality or consistency of the brushing, the dial’s appearance in changing light, or how clearly the hands stand out in actual use.
The listed butterfly clasp includes 1.5 to 3 mm of micro-adjustment. That range may help refine fit, but the product copy does not show whether it will provide enough adjustment for a particular wrist or how convenient the clasp is to operate. The 24 mm lug figure is also worth noting when assessing proportions, though an integrated bracelet is not a conventional strap setup. Bracelet feel, articulation and clasp performance require hands-on evaluation.

Is the 100 m water-resistance rating enough?
YEMA publishes a rating of 10 BAR / 100 m / 330 feet and specifies a screw-down crown. This is a manufacturer rating, not independent proof of the watch’s condition or water resistance in use. Buyers should follow YEMA’s guidance and warranty terms for water exposure rather than treating the number as a substitute for a pressure test, particularly on a pre-owned watch or one that has been serviced.
Price, availability and warranty
At the time reflected in YEMA’s official US listing, the reference was priced at $2,449 and marked sold out. The listing’s date is not stated, so that figure should not be treated as a current offer. Confirm availability, price, shipping, returns and the warranty terms for your region directly with YEMA before buying.

The Wristmaster Slim CMM.20 Limited Edition is most relevant to buyers specifically seeking an integrated-bracelet design, a slim stated profile and the mechanical interest of an automatic micro-rotor. Its stated 200-piece run may also matter to collectors who value limited production, although edition size alone says nothing about future desirability or resale value.

Before deciding, prioritize the questions the published specifications cannot settle:
- Does the case and integrated bracelet suit your wrist when tried on?
- Does the dial remain legible in the lighting conditions where you expect to wear it?
- Does the clasp’s adjustment range give you a secure, comfortable fit?
- Are the price and warranty terms acceptable for your region and the watch’s current availability?
- If buying used, has the watch’s water resistance been checked and is its service history documented?
YEMA’s Wristmaster collection page shows other models in the family, including CMM.20 and small-seconds variants. They are not automatically equivalent alternatives: compare each reference’s dimensions, movement, bracelet and clasp, water-resistance rating, price, availability and warranty before treating it as a substitute.
