For permanent maintenance.
To make watches that will be treasured for more than 100 years … our goal is to make watches that can still be used even after 100 years. The MORE* structure adopted in the Master Craft Series reflects this philosophy. The MORE structure, which is inspired by Japanese traditional wooden puzzles, allows all external parts to be assembled and disassembled like a wooden puzzle. Therefore, every part can be replaced individually, which prolongs product life and facilitates maintenance.
For instance, a bracelet is generally completed by assembling segments and then pressing them from both sides. Such bracelets are robust, but cannot be disassembled in case of damage. In contrast, the Master Craft Series bracelets can be completely disassembled, and so it is possible to repair or replace only the damaged parts. The MORE structure is also used in the DIVIDO, a new work of the HiZ Series.
In general, disassemblable bracelets tend to become longer with use, and so other manufacturers prefer not to use such bracelets. Disassemblable bracelets are no longer used even for ultrahigh-quality watches. However, we succeeded in creating bracelets having appropriate play and high durability by taking advantage of our expertise in precision machining and assembly. This was made possible by our expertise in precision machining as well as our highly skilled craftsmen.
* MORE stands for Minase Original Rebuilding Equation. MINASE patented the MORE structure for wrist watches (Pat. No. 4671327) and for watch bands (Pat. No. 4674698).
