Ōtsuka Lōtec is a Japanese independent and GPHG Award-winning watchmaker founded by Jiro Katayama. His pieces are available from retail exclusively in Japan, further enhancing their appeal in other parts of the world. The No. 7.5 is a model blending design elements of steam punk to utilitarian futurism. It houses a MIYOTA movement that leverages a proprietary in-house module to power a jump hour mechanism with hours, minutes and seconds on separate discs. The exterior finish combines straight graining and sandblasting, highlighting the case’s interplay of clean lines and smooth curves—offering a fresh visual experience with each glance. This example comes as a complete set from 2024 and is undeniably the perfect conversation piece for any collector looking for something off the beaten path.
