Yema, a brand recognized for its distinctive timepieces, has recently unveiled a limited-edition iteration of its Skin Diver Slim, emphasizing a striking full-lume design. This release is a notable part of 'The Five Acts' series, a collection showcasing Yema's manufacturing prowess and design evolution through various materials, hues, and mechanical innovations. The Skin Diver Slim, with its luminous features and modern internal movement, offers a compelling blend of heritage and contemporary watchmaking.
Details of the Luminous Skin Diver Slim
The Yema Skin Diver Slim Full Lume CMM.20 Limited Edition maintains the iconic 39mm stainless steel case, a familiar sight from previous Skin Diver models, with a balanced lug-to-lug measurement of 47mm. Its slender profile, measuring 12.2mm overall (with a case thickness of 9.9mm), is attributed to the double-domed sapphire crystal. This robust diver boasts a 300-meter water resistance and features a largely brushed finish accented by polished bevels. The unidirectional diving bezel is fitted with a black sapphire insert, displaying a white 60-minute scale that emits a vibrant blue glow in low light, complemented by a cream-colored lume pip at the 60-minute mark that shines green.
The luminous theme extends to the dial, which initially appears as a crisp white surface but transforms into a brilliant blue in the dark. Black applied hour markers, filled with cream-colored Grade A Super-LumiNova, glow a vivid green, creating a striking contrast. The larger markers at the cardinal positions (3, 6, 9, and 12 o'clock) retain their unique, retro-inspired numerals, adding a touch of vintage character. The black hands also feature the same cream-colored lume, ensuring consistent green illumination. Completing this radiant aesthetic is a white FKM rubber Scales strap that mirrors the dial's blue glow in darkness, contributing to an immersive luminous experience.
Powering this timepiece is Yema's in-house Calibre Manufacture Morteau 20 (CMM.20), an automatic movement operating at 28,800 vibrations per hour, offering a substantial 70-hour power reserve, and achieving an accuracy of -3/+7 seconds per day. This slim, modern caliber incorporates a bidirectional tungsten micro-rotor, Incabloc shock protection, and a Glucydur balance wheel. It also features elegant satin finishing and micro-blasted treatment on its mainplate and bridges, all enhanced by a black Atomic Layer Deposition (ALD) coating. This dark finish harmonizes with the watch's black bezel insert, lending a contemporary feel that surprisingly complements its retro design roots.
Personal Impressions and Reflections
Having experienced numerous Yema watches, I've always been drawn to their classic designs, particularly the Skin Diver series, with its distinctive retro hour markers. This new full-lume variant elevates the charm of the Skin Diver Slim, offering a visually captivating experience in low-light conditions. The luminous strap, though prone to losing its pristine white over time, perfectly aligns with the watch's overall glowing concept. On the wrist, the watch is comfortable and well-proportioned, fitting my 18.5cm wrist perfectly, and its thin profile adds to its wearability. My frequent tests in dim environments consistently revealed a watch that truly stands out, particularly when activated with a lume torch.
The 'Five Acts' series as a whole demonstrates Yema's growth and innovation, showcasing their advancements in in-house calibers and their ability to integrate modern materials and colors with classic designs. This particular limited edition is a testament to that vision, offering a fresh, contemporary twist on a beloved vintage model. With only 400 pieces available, each priced at approximately €2,450 / US$2,725 / £2,200, this luminous Skin Diver Slim is an accessible yet distinctive offering for Yema enthusiasts seeking a watch that blends nostalgic appeal with cutting-edge illumination and a robust in-house movement.
