Minase, a workshop based in Minase, Akita Prefecture, unveiled a "pocket watch" based on the concept of Japanese craftsmanship. The 12-sided case, polished with Zaratsu finish, incorporates traditional techniques such as maki-e (gold lacquer) and the black rust effect of Japanese swords, creating an art piece that embodies a distinctly Japanese sensibility and aesthetic. Two models are available, each featuring the "Asagi-madara" butterfly (a migratory butterfly) and the "Houou" (phoenix), and are offered in stainless steel and 18K gold variations. All models are made to order.

 Japanese watch brand Minase has unveiled a new collection titled "Timeless Japanology." This time, the brand chose to express unique Japanese craftsmanship through a "pocket watch" rather than a wristwatch. Traditional techniques such as Zaratsu polishing, maki-e lacquerware, and the black patina of Japanese swords are condensed into a 12-sided form.

 One of the highlights of this collection is the maki-e dial created by lacquer artist Junichi Hakose. Two motifs, the "Asagi-madara butterfly" and the "phoenix," are depicted with exquisite craftsmanship.

 The Asagi-madara butterfly is a butterfly that travels 1500km across the sea, and the design of this pendant watch embodies the craftsman's wish that it will serve as a bridge between cultures. To represent its distinctive pure white wings, a sophisticated technique called "eggshell" is used, in which finely crushed quail eggshells are arranged.

 On the other hand, the Phoenix model features a meticulously detailed depiction of the legendary mythical bird, said to herald peace and prosperity, down to the finest downy feathers that are invisible to the naked eye. The eyes are added at the end of a process that takes several months, giving the dial an overwhelming presence that makes it seem as if it has come to life.

In the creation of maki-e dials, the base brass plate is first baked with gold leaf, and then the lacquering, drying, and polishing processes are repeated many times to form the base. Gold powder is then sprinkled on top, and the lacquering and polishing are repeated again, a tremendous amount of work that takes several months to complete a single dial.

 Furthermore, traditional Japanese craftsmanship is evident in the case back and the hanging loop for the strap. The material used is precious "tamahagane," refined using the tatara ironmaking method. Swordsmith Ishida Kunihisa forged this steel and applied the black rust (kurosabi) seen on the tangs (nakago) of Japanese swords.

 This black rust, through repeated handling and care, will gradually transform into a deep, purplish black (yokan color) over a long period of 50 to 100 years. It's a romantic feature that is completed through generations of "cherishing" it.

Tamahagane refers to high-quality steel with extremely few impurities, refined using the traditional "tatara ironmaking" method. Swordsmiths heat the tamahagane in a roaring charcoal fire and repeatedly fold it into layers by hammering it. This process removes impurities and excess steel, transforming approximately 7-8 kg of tamahagane into a less than 1 kg mass of high-purity steel.

The steel forged by the swordsmith is first sent to Minase's factory, where it is processed into a case back and a hanging ring. Then, it is sent back to the swordsmith, where it is repeatedly rusted and filed down to its final finish.

 The dodecagonal middle case is available in stainless steel or 18K gold. This polygonal form highlights the sharp edges and distortion-free surface created by Zaratsu polishing. Inside the case is the Cal.KT5002, a hand-wound movement based on the Chronode Cal.C101. It boasts a long power reserve of approximately 162 hours and offers excellent practicality as a hand-wound watch.

The watch comes with luxurious accessories including a wooden watch stand, stainless steel ornaments, two braided cords of different lengths, and a leather pouch. The wooden stand, in particular, is specially made by craftsmen who individually apply lacquer and attach ornaments that have been polished to a mirror finish using Zaratsu polishing.

The watch and its accessories are housed in a special box made from Akita cedar.

 Please note that all models are made to order, and it will take approximately six months to a year from the time of order until the product arrives.
