A classy timepiece with elegance and finesse
The Luna Arch watch features a simple yet refined form, with an unpretentious yet impressive presence and luxurious contours.
The design of its bezel, which is clasping sapphire crystal glass from the top, is inspired by the bezel-setting technique used in jewelry-making. The watch exudes a sense of luxury, with the transparent sapphire crystal glass visible through the gap between the bezel and the case giving an airy look.
The dial pattern is inspired by how light randomly reflects off the surface of the Minase River, which glitters when viewed from any angle. The watch can be worn for special occasions as well as everyday use.

The MORE structure ensures perpetual maintenance.
Our philosophy is to make watches that can last and be treasured for over a century, so we invented the MORE* structure. Inspired by the traditional Japanese craft of kumiki-zaiku (wood interlocking work), the MORE structure enables a watch to be disassembled into all its constituent parts. As this allows any single part of a watch to be replaced as needed, it prolongs the watch’s usable lifespan while reducing the need for maintenance.
*Minase Original Rebuilding Equation: MINASE has one registered patent (patent no. 4671327) related to watches and another registered patent related to watch bands (patent no. 4674698).
MINASE’s signature finish attained by its world-class sallaz polishing technique
MINASE excels at Sallaz polishing, a machining technique, like no other. This unique technique, which originated with Swiss machining equipment called sallaz many years ago , is a method of preparing the substrate before surface finishing a watch’s case. Usually, the processes of manufacturing a watch’s case involve forging and cutting followed by buffing to achieve the desired surface quality. However, if the substrate is prepared with the sallaz technique before the final buffing, the polished surface will achieve a perfectly clear mirror finish with minimal distortion. Come try on a MINASE watch to see its dazzling finish for yourself.
MINASE’s proprietary clamping case structure
The clamping case structure involves inserting the glass between the bezel and the case and clamping them together from underneath, which makes the watch more water-resistant.
Luna Arch is designed with the bezel placed on top of the glass similar to the bezel-setting technique used in jewelry-making. This structure exposes the rim of the sapphire crystal glass placed beneath the bezel so that it can be seen from the side across the entire circumference, giving it an airy look.
Meanwhile, Uruga features a structural design wherein the bezel, the glass, and the case are clamped together from both top and bottom using four separate parts, resembling how gemstones are set on pieces of jewelry.
