Full-Cataloguing
Good to know:
- The “Challenge” award winner at the GPHG 2024
- Modified Miyota movement with in-house retrograde module
- “Brand-new” condition with full set of accessories
Jiro Katayama’s unique designs stand out amongst the conventional designs we see in the Japanese watch market. From the pressure gauge-like appearance of Model No. 6, it is not difficult to speculate that he draws inspiration from analogue instruments for his watch designs. The Model No. 6 was awarded the winner of the “Challenge” award at the Grand Prix d'Horlogerie de Genève 2024. In the same year at the Phillips TOKI: Watch Auction it held a stunning record of being auctioned at HKD469,900, exceeding ten times more than the higher estimate.
Insisted to be “Made in Japan”, like other models offered by the brand, movements are usually sourced from Miyota, then in-house developed modules are attached depending on the configuration of the models. The present watch is fitted with the Miyota cal. 9015 with a retrograde movement developed by Katayama. The in-house crafted hands and case, alongside the Japanese engravings on the dial, give a bold industrial impression combining with a touch of modernity in contemporary Japanese watchmaking.
The present lot in “brand-new” condition, accompanied by its original accessories, is the perfect watch for collectors that enjoy an unusual retrograde timepiece with industrial aesthetics.
