With our inaugural release, the Addendum, we push the boundaries of watch design with our uniquely shaped bezel which integrates the large crown seamlessly without interrupting case symmetry.

The case subtly curves downwards, flowing into the wearer’s wrist for a comfortable and ergonomic fit suited for every use. An all or nothing approach to watchmaking that does not sacrifice features and specifications for design. YLEM will continue to lead the industry with the next generation of design ideas, while making very capable watches suited for every occasion.
