TOKYO — Nineteen years in the past, when he started working at a manufacturing unit that made watch straps, Kunitaka Kojima thought they had been simply one thing that got here together with a timepiece. “I underestimated watch straps,” he mentioned.
Now Mr. Kojima, 48, is an unbiased artisan who makes them by hand: “My want is to take advantage of stunning watch straps on this planet, that shall be used and admired for a very long time.”
In 2012 he established his personal model, Galuchattail. Galuchat is a time period for stingray and shark leathers (named — though misspelled — for Jean-Claude Galluchat, Louis XV’s grasp artisan, who launched the unique supplies to France in the course of the 18th century). As for the phrase “tail” within the model title, Mr. Kojima mentioned, it refers to “the stingray’s tail, which is sharp and edgy, how I need my designs to be.”
The straps, which begin at 150,000 yen ($1,085) for the best model in crocodile, are designed to be taken aside for repairs. “If the fabric is broken, you’ll be able to substitute it, or if the loop breaks, you can also make a brand new loop and restore it time and again,” Mr. Kojima mentioned.
His clientele consists of watch collectors from around the globe, unbiased watchmakers in Switzerland and Japan and microbrands similar to Naoya Hida & Co., the Tokyo maker that outfitted its first watch, the Kind 1C, with a hand-stitched brown leather-based strap from Galuchattail.
Mr. Hida mentioned his preliminary go to to Mr. Kojima’s workshop was in 2018. “I used to be tremendously impressed by his unparalleled dedication to high quality and creativity,” the watchmaker mentioned. “I instantly requested him to provide leather-based straps for our watches.”
Leatherwork is a part of Mr. Kojima’s heritage. An amazing-grandfather was a tanner and, as a toddler, he performed with small items of leather-based from his mother and father’ leather-based manufacturing unit.
When he started working, he spent seven years as a tailor, however the price of gear deterred him from opening a store. “I used to be searching for work the place I might use my reducing and stitching expertise, so I joined a watch strap manufacturing unit in Tokyo,” he mentioned, noting that he was a part of a six-member workforce that produced 20,000 straps every month. “I labored 18-hour days, from 8 a.m. to 2 a.m., with sooner or later off monthly.”
The thought of a strap that could possibly be repaired intrigued Mr. Kojima, and he arrange a small atelier in Asakusa, a district on Tokyo’s japanese facet that’s identified for the Senso-ji Buddhist temple, a serious vacationer attraction. Asakusa additionally was the place Mr. Kojima was born and raised, though he now lives in Ebisu, on town’s west facet (“I hold a sleeping bag within the atelier,” he mentioned, “for once I’m too centered on manufacturing and I can’t return dwelling after the final prepare runs out”).
In July, Mr. Kojima walked some visitors, together with myself, by way of the method of creating his three strap types: the 3-D Flex, a strap that matches the curve of the client’s wrist; the 2-D Straight; and the Prepared-Made, which, regardless of its title, is also customizable. He mentioned that an ordinary Prepared-Made strap might take three to 5 hours to finish, however {that a} custom-made one might take so long as six months.
Select the Materials
Mr. Kojima makes use of each form of animal pores and skin, however his signature selection is galuchat, which he buys from Thailand and Indonesia through Japanese leather-based wholesalers. He mentioned he most well-liked items which might be about 12 inches by 6 inches as a result of the floor pebbling, additionally referred to as denticles, is proportionally small and appears higher than on bigger skins. Whereas he makes use of each bit of every piece, the portion with the white star-shaped mark discovered on a stingray’s backbone instructions a premium, elevating the price of a {custom} 3-D Flex galuchat strap to ¥250,000 from the standard ¥220,000 value. “The star mark is taken into account a good-luck appeal that brings you in direction of the sunshine,” Mr. Kojima mentioned. Then he displayed a stingray conceal coated in star marks, noting, “I waited 5 years to acquire it for a buyer.” When that strap is completed, he mentioned, it would price round ¥500,000.
Sprucing and Dyeing
Mr. Kojima dyes his personal skins. “For galuchat, I first polish the denticles one after the other, by hand, with a file to take away the small scratches, and polish them till they shine,” he mentioned. Then he makes use of a brush to use the dye, normally darkening the colour as he works it towards the perimeters. “Nonetheless, when dyed, the luster turns into a bit of cloudy, so I polish it manually once more after the dye has dried,” he mentioned. “And once you polish it, the colour of galuchat will fade a bit of because of friction, so I dye it once more.” He repeats the whole course of, typically as many as 10 instances, a course of that would take so long as a month.
Becoming
For a {custom} order, Mr. Kojima measures the consumer’s wrist with a particular gauge, an orange and black piece of plastic that envelops the wrist and appears like one thing made from Legos. “It’s the identical as garments’ tailoring, apart from a wrist,” he mentioned.
Designing and Reducing
Utilizing the measurements, he attracts the strap on graph paper after which, guided by the sketch, creates a sample from a clear sheet of plastic about half a millimeter thick. He then organizes his supplies in a form of sandwich: the galuchat; the core layer, a robust materials referred to as Cordura, made by the U.S. firm Invista; and the liner, which normally can also be a leather-based (Mr. Kojima recommends sharkskin as a result of its uneven floor means the strap is unlikely to stay to the wearer’s wrist in sizzling climate). He locations the sample on prime after which cuts by way of the layers utilizing a leather-based knife made by a blacksmith who makes a speciality of Japanese swords.
Shaving
“Earlier than I assemble the watch strap, I shave the leather-based so the strap doesn’t look untidy and I modify the thickness of the leather-based,” Mr. Kojima mentioned, displaying a kawasukiki shaving machine from the Sixties that he picked up secondhand. To show, he put a strip of leather-based in opposition to the machine’s spinning wheel, which rubbed it till Mr. Kojima determined it was skinny sufficient to make use of.
Stitching and Assembling
As stingray leather-based may be very exhausting, Mr. Kojima makes use of a small hand drill with a spiral bit to create holes and switches to a pointy straight bit to redrill each. Then, with a bent needle and polyester thread coated with wax, he stitches by way of the galuchat and the core materials (however not the liner as a result of, he mentioned, that may enable sweat or water to work its method up). “I sew by hand as I can completely management the strain and pace, not like utilizing a machine,” he mentioned. Lastly, Mr. Kojima makes use of one of many 5 adhesives he retains readily available to connect the liner.
Ending
Mr. Kojima has his personal methodology to seal a strap’s edges. First, he brushes dye on the uncooked edges after which applies a wax that he formulated. As soon as it’s all fully dry, he heats a trowel over a lamp and gently rubs the nice and cozy instrument over the perimeters to make the wax permeate the leather-based. He repeats the method 21 instances to attain a shiny and resistant edge, a course of that typically takes a couple of week. “Portray the border means it’s simply repairable if broken, and it’s additionally sweatproof and waterproof, because the water can’t enter,” he mentioned. As for the buckle, Mr. Kojima will make one, or reuse one from an outdated strap supplied by the client.
The strap now could be accomplished. Together with his endurance, dedication to perfection and detailed explanations, I instructed Mr. Kojima he must be a trainer. “My dream is to open a college,” he mentioned. “I’d like to show younger craftsmen to grasp the essence of creating a watch strap.”
