Creator Consensus

Very positive

7 reviews: 7 positive, 0 mixed, 0 negative. 7 of 7 recommend it.

Every reviewer recommends it and rates both the design and the movement positively. Most praise the grey dial with cream lume, the characterful scale-link bracelet and the faithful nod to 1960s originals, and most find the in-house micro-rotor impressive at this level. The main recurring complaint is a stamped clasp that several reviewers find cheap and dated.

Where they differ. On value, several reviewers say it competes well with rivals while some feel it carries a notable premium. Some also find it thicker than ideal, even as others note it sits flat and slips under a shirt cuff.

Hands-On With The Yema Skin Diver Slim CMM.20 Limited Edition

ArticleHands-on reviewJul 2024Jorg Weppelink

PositiveRecommends, with caveats

The reviewer loves the vintage 60s styling, gray colourway, balanced 39mm case and comfort, calling it a personal second-favourite Yema. However, the bracelet clasp feels subpar, the prototype showed finishing flaws, and the price premium over cheaper Yema divers makes value a question.

Suits: Yema fans who love the vintage Skin Diver style and micro-rotor movement

Disclosure: Brand loaner

What the review says, point by point

Designpositive: Loves the vintage styling across the case, dial and bracelet.
Finds the overall design visually balanced on the wrist.
Considers the gray hue a welcome alternative to typical dial colours.
Dialpositive: Thinks the black numerals in the cardinal markers suit the design.
Feels the gray complements the prominent beige lume on the large markers.
Case & proportionspositive: Sees the 39mm-only case as the right choice, more balanced than Yema's 41mm divers.
Prefers the new 10-minute bezel numerals and welcomes the absence of a bezel lock.
Finds the oversized crown visually interesting and practical.
Wearabilitypositive: Says the dimensions fit various wrist sizes well.
Reports that the watch wears very comfortably.
Bracelet & strapmixed: Finds the bracelet's vintage style complements the watch well.
Notes the flexible scale links wrap well around the wrist.
Rates overall bracelet quality as merely decent.
Criticises the stamped, rattly clasp as outdated and hard on fingernails.
Movementpositive: Views the micro-rotor diver as a good bridge between Yema's heritage and innovation.
Finds the black-coated modern movement finish an interesting contrast with the vintage style.
Finishing & buildmixed: Considers the case and bracelet nicely finished.
Found questionable hour hand finishing under a loupe on the prototype.
Versatilitypositive: Says the subdued gray makes the watch easy to match with varied outfits.
Originalitypositive: Values the outspoken, quirky design that stands out within Yema's collection.
Notes the marker style is shared with other skin divers like the Oris Diver Sixty-Five.
Valuemixed: Feels the vintage charm and micro-rotor carry a notable price premium.
Believes the higher price demands better bracelets and clasps, amid stiff competition.
Sees limited-edition status and the micro-rotor as legitimate reasons for fans to pay more.
Compared with: Oris Diver Sixty-Five: Shares similar-style trapezoidal hour markers with Arabic numerals.
Seiko 62MAS: Comes to mind for its similar gray colour.
Yema Superman FAF Search And Rescue Limited Edition: Reviewer's favourite Yema, and much cheaper at €1,199.
Yema Superman 500: Skin Diver more interesting in design, but Superman 500 far cheaper.
