The Ōtsuka Lōtec No. 9 has a lot going on, which isn’t surprising for a watch in development for over nine years. Gone (in this model) are the affordable takes on interesting displays like starwheels, jump hours, and retrograde hours and minutes that won Ōtsuka Lōtec a “Challenge Prize” at GPHG 2024. Katayama has gone full tilt into higher complications here, combining a jump hour, “rewinding minutes,” tourbillon, power reserve, and sonnerie au passage or “striking hours” into a stainless steel case measuring 41.3mm by 26.4mm with a thickness of 10.35mm. That’s 278 components in a small package, and judging from the photos, it’s impressive.
