Owner’s Review: the Ōtsuka Lōtec No. 8 Worn & Wound
Breguet numerals outperform another? But 5h ago

Owner’s Review: the Ōtsuka Lōtec No. 8

I occasionally have a hard time understanding why some brands are so popular. It’s not that they don’t deserve to do well, but I see brands that don’t seem to be doing anything much different from their peers, let alone special, yet are many times more hyped. Why does one Calatrava-esque watch with Breguet numerals outperform another? But with Ōtsuka Lōtec, I get it. In fact, I don’t just get it, I’ve fallen for it. Then again, Ōtsuka Lōtec isn’t like any other brand. Jiro Katayama, the brand’s founder and lead designer/watchmaker, works from a different playbook. Where other brands pursue finishing and neoclassical elegance, he seeks beauty in the raw and industrial. Inspired by analog machines, measuring instruments, gauges, and the industrial design of the pre-digital age, there is something rough and unintentional (though completely intentional) about his watches. Considering he taught himself watchmaking in a workshop nestled in Tokyo, there is a certain logic to this aesthetic. It’s not born in the farm-strewn hills of Jura, but rather in one of the densest cities in the world. Nor is his education from a lineage of tradition. You won’t find perlage or anglage; surfaces are typically raw, brushed metal, and rarely painted, with only the occasional red highlight. While potentially a love-it-or-leave-it aesthetic, it has resonated deeply with the watch community, touching on a pure joy of mechanics. But, there is more to it as well, as his watches...

Hands-on - The Otsuka Lotec No.8 Refines Jiro Katayama’s Industrial Language

We wouldn’t go as far as to say that there’s something fundamentally different about the way Jiro Katayama approaches watchmaking. After all, industrial design, be it cars, instruments, or machinery, has inspired and defined quite a few independents. Still, most start from horology and branch outward, yet the mind behind Otsuka Lotec comes directly from […]

Otsuka Lotec Introduces the No. 8, a New Design Inspired by Abbey Road Mixing Consoles Featuring Jumping Hour and Retrograde Minute Displays

Otsuka Lotec has emerged as one of the most exciting Japanese independent brands, a corner of the enthusiast world that is greatly expanding at the moment. Otsuka Lotec has found a niche with (mostly) affordable watches with a steampunk aesthetic, with lots of exposed gearing and an overtly mechanical look and feel. I’m an owner of the No. 5 Kai, and it’s one of the most satisfying watches in my collection – there’s really nothing else quite like it, at least under $10,000. Prior to this week, the latest release from the brand was an ultra high end complicated piece with a tourbillon and chiming mechanism with a retail price soaring into the low six figures, but they’ve returned to earth with the all new No. 8, which once again combines complications unexpectedly and gives the wearer a unique view of the mechanism inside.  Like the haute horlogerie adjacent No. 9 linked above, the No. 8 features a square case fashioned from stainless steel. Time is read via a jumping hour display on the left side of the dial, and a retrograde minute display on the right (there is also a running seconds indicator at roughly the 12:00 position). Figuring out how to read the time when you first encounter a watch like this is part of the fun, but once you grasp what’s going on, it’s quite intuitive. The current hour and minute are easy to see at a glance if you look for the red indicators that correspond to each. A video posted on Otsuka Lotec’s YouTube channel makes the drama...

Introducing - Otsuka Lotec Presents its New Creation, the No.8 Jumping Hour and Retrograde Minute

Otsuka Lotec… The Japanese brand (or should we call it an atelier) that makes some noise in the global watch collecting community, despite being unavailable outside of Japan – which might partially explain its popularity. A true JDM sensation, Otsuka Lotec is the brainchild of Jiro Katayama, a car designer turned self-taught, independent watchmaker, specialised […]

Ōtsuka Lōtec Debuts the New No. 9, an Experiment in Haute Horology

Ōtsuka Lōtec had a viral moment over the weekend with the surprise launch of the No. 9, the latest creation from the Japanese microbrand headed by designer and watchmaker Jiro Katayama. These watches have captured the attention and imagination of enthusiasts worldwide for their unique steampunk aesthetic, filtered through a unique Japanese industrial design perspective. Up until now, their watches have been defined by interesting complications (wandering hours, retrograde displays, etc.) at ultra competitive price points topping out at around $5,000, and being genuinely difficult to obtain outside of Japan thanks to extremely limited production and simply not being offered to en masse to those outside the country. With the No. 9, it certainly appears that Ōtsuka Lōtec will continue to make watches that are tough to obtain, but they’ve thrown the pricing structure out the window with this release, offering up a far more complicated watch than anything they’ve previously attempted.  The No. 9 is a rectangular watch in a stainless steel case measuring 41.3mm by 26.4mm. It’s 10.35mm tall, which makes this a quite compact package, and all the more impressive given the mechanical complexity. Going through the list of features and mechanical complications here is going to be a bit like the Stefon sketch on SNL (“This watch has everything…”) so let’s just embrace it: across 278 components, this watch features a tourbillon, a jump hour, “rewinding minutes,” a...
