# Perplexing Artistic Timepieces The Otsuka Lotec No.5 KAI Has a 40.5mm Stainless Steel Case By Michael Hemsworth | Published 2025-01-22 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/otsuka-lotec-no5-kai References: [hiconsumption](https://hiconsumption.com/watches/otsuka-lotec-no-5-kai/) & [otsuka-lotec](https://otsuka-lotec.com/models/521/)  The [Otsuka Lotec](https://www.trendhunter.com/trends/tsuka-ltec-no9) No.5 KAI timepiece has been showcased by self-taught watch designer Jiro Katayama as a slightly perplexing timepiece that will no doubt catch the attention of new and existing fans of the brand. The watch is paired with a series of cruciforms on the dial that each have four numerals on their stems that will shift perplexingly across the surface to perform something of a ballet as they transition throughout the day to indicate the time. The watch features a stainless steel case that measures in at 40.5mm and 7.6mm in thickness, which is extended up to 12.2mm thanks to a [thick sapphire crystal lens](https://www.trendhunter.com/trends/amida-digitrend-open-sapphire). The Otsuka Lotec No.5 KAI timepiece is powered by the [Miyota](https://www.trendhunter.com/trends/kiwame-tokyo-iwao-sumi) 90S5 automatic movement with 40-hours of power reserve and will be available via lottery in Japan for JPY 748,000.
