Yema Skin Diver Slim Full Lume CMM.20 Limited Edition 12.26.20.67.SNL.U7

FULL-LUME SKIN DIVER DIAL

The dial was conceived as a true light source. Its full-lume white surface ensures immediate readability, while the applied indices are framed in matte black and paired with black hands for a sharp contrast in daylight. The classic Skin Diver layout remains intact, with its broad arrow minute hand, thinner hour hand, and "lollipop" second hand, preserving the collection's unmistakable personality. Printed black lettering and minute markers keep the composition clean, balanced, and easy to read.
