Ōtsuka Lōtec is an independent Japanese watch brand founded in Tokyo by designer and watchmaker Jiro Katayama. Inspired by analogue instruments and industrial machinery, its watches combine sculptural steel cases with unconventional displays and a distinctly mechanical character. Before entering watchmaking, Katayama worked in automotive and product design. His journey into watches began around 2008, after purchasing a small bench lathe at an online auction. What started as an experiment in metalworking gradually developed into a watchmaking practice, with his first pieces offered for sale in 2012. Katayama finds inspiration in the construction, textures and movements of everyday objects. Exposed screws, rotating discs and instrument-style scales give his watches a tactile quality, reflecting his appreciation for objects shaped by their function. Each model pairs a Japanese Miyota automatic movement with a proprietary display module developed by Ōtsuka Lōtec. These modules define the collection, bringing jumping hours, double retrograde indications and satellite time displays to life. For collectors, Ōtsuka Lōtec offers a distinctive expression of independent Japanese watchmaking: inventive mechanics, a coherent design language and the unmistakable personality of its creator. Ōtsuka Lōtec № 7.5 The Ōtsuka Lōtec № 7.5 approaches timekeeping with the character of a miniature mechanical instrument. Three raised windows display the hours, minutes and seconds separately, giving the watch its distinctive three-dimensional silhouette. At the heart of the display is a jumping-hour mechanism. The hour numeral changes instantaneously at the start of each new hour, while rotating discs indicate the minutes and seconds. A sapphire magnifying lens brings the hour display into focus and reinforces the watch’s instrument-like appearance. The 40 mm case is crafted from 316L stainless steel, combining straight-grained and sandblasted finishes. These contrasting textures emphasise the interplay between flat surfaces, curved edges and raised viewing windows, making the case engaging from every angle. Inside, a Miyota 82S5 automatic movement is paired with Ōtsuka Lōtec’s proprietary jumping-hour module. The watch offers approximately 40 hours of power reserve, with a transparent caseback revealing the base movement. With its unusual architecture and animated display, the № 7.5 is a compelling choice for collectors drawn to inventive design and a more playful interaction with mechanical time.

Calibre MIYOTA 90S5 is a self-winding mechanical movement with a power reserve of 72 hours.
