Catalogue Essay
Jiro Katayama, the founder of the brand Ōtsuka Lōtec, has cultivated a considerable following among discerning collectors. Though distributed solely in Japan, Ōtsuka Lōtec has earned global recognition for its distinctive, steampunk-inspired creations.
Following the success of Ōtsuka Lōtec's Phillips debut in last year's TOKI auction, we are thrilled to present the first "No. 5 Kai" at auction. The Ōtsuka Lōtec No. 5 Kai is Katayama’s latest creation, and it stands apart from nearly every perspective. Viewed head-on, it features a wandering hours display; from the side, it reveals an ultra-thin stainless-steel case topped with a dramatically thick box-style sapphire crystal. True to Ōtsuka Lōtec’s aesthetic, the finishing combines visible brushing, media-blasting, and a muted, low-contrast palette punctuated by sharp angles and protruding forms. The crown at 4 o’clock perfectly exemplifies this brutal industrial design: the caseband is recessed to make space for the pronounced crown tube, which flares into a large, aggressively knurled knob.
At the time of launch, it was exclusively available in Japan via an online lottery system hosted on the brand’s website.
