Yema continues to innovate and expand its impressive collection, with a particular emphasis on integrating its exclusive calibers into more of its timepieces. This initiative led to the launch of the Skin Diver with the CMM.20 movement last April. As the new year begins, the French watchmaker is once again highlighting this classic diver, introducing two Skin Diver Slim Bronze CMM.20 models: one in dark gray, available as a limited edition, and another in stylish green, joining the permanent collection. These new releases demonstrate Yema's ongoing commitment to pushing boundaries and enhancing its range with in-house movements.

The latest additions to the Yema Skin Diver Slim Bronze CMM.20 line are a testament to the brand's dedication to quality and design. Both models boast a 39mm bronze case, a slim 12.2mm profile, and a 47mm lug-to-lug measurement, ensuring a comfortable fit. The cases feature a sophisticated brushed finish complemented by polished bevels, creating an appealing visual contrast. With a water resistance of 300 meters, facilitated by an oversized screw-down crown, these watches are built for performance. Each model is equipped with a bronze bezel, topped with a sapphire crystal insert, with the gray limited edition sporting a 'ghost' bezel and the green variant featuring a vibrant green insert with crisp white numerals.

The Legacy of the Yema Skin Diver Slim Bronze CMM.20

The introduction of the new Yema Skin Diver Slim Bronze CMM.20 models may seem like a natural progression following the 2025 update to the standard Skin Diver series, but their story actually began earlier. In the summer of 2024, Yema unveiled a limited-edition Skin Diver Slim powered by the CMM.20 caliber, which garnered significant attention. These new bronze versions represent a further evolution of that slimmer design, now offered with a choice of a dark gray or a stylish green dial. This continuous development showcases Yema's strategic focus on integrating advanced proprietary movements into its classic models, ensuring both heritage and innovation are celebrated.

These watches draw inspiration from the iconic Yema Skin Diver of the 1960s, blending historical charm with contemporary engineering. The 39mm bronze case, featuring a blend of brushed and polished surfaces, offers a robust yet elegant presence on the wrist. Its 12.2mm thickness and 47mm lug-to-lug dimension provide a balanced wearability. A notable feature is the 300-meter water resistance, achieved partly through an imposing screw-down crown. Each model's bronze bezel is adorned with a sapphire crystal insert; the gray limited edition features a discreet “ghost” bezel, while the green version stands out with its vivid green insert and contrasting white markers. This meticulous attention to detail ensures that each watch is not just a timekeeping instrument, but a piece of history re-imagined for the modern enthusiast.

Dial Design and Precision of the Yema CMM.20 Movement

Each timepiece is completed with a matte enamel dial that perfectly complements the color of its bezel insert. The dials are characterized by their trapezoidal hour markers, including distinct numerals at the 3, 6, 9, and 12 o'clock positions, enhancing readability and maintaining a classic aesthetic. The gray-dial version utilizes a subtle lime-colored Super-LumiNova for its hands and markers, accented by bronze-toned text, giving it a sophisticated and unified look. In contrast, the green-dial model features sharp white Super-LumiNova on its indexes and hands, along with matching white dial text, creating a clean and vibrant appearance. These deliberate color choices ensure each variant possesses a unique character, appealing to different preferences while upholding the collection's refined appeal.

At the core of these watches lies the sophisticated CMM.20 movement, visible through the case back. This in-house micro-rotor caliber, crafted at Yema’s manufacture in Morteau, boasts a slender 3.7mm thickness. It features a bidirectional tungsten micro-rotor, Incabloc shock protection, and a Glucydur balance wheel, all contributing to its reliability and precision. Operating at a frequency of 28,800 vibrations per hour and offering a robust 70-hour power reserve, the CMM.20 ensures consistent and accurate timekeeping with a daily deviation of -3/+7 seconds. The movement is also distinguished by its modern finish, including a micro-blasted mainplate and bridges, and a black ALD (Atomic Layer Deposition) coating, showcasing Yema’s commitment to both technical excellence and aesthetic appeal in its movements. The integration of this advanced movement underscores Yema's dedication to combining its historical diving watch designs with cutting-edge horological technology.
