Kurono Tokyo 34mm

"Nowadays, who would want a 34mm watch? Regardless, I prefer watches of this size. That is also why I am enamored with vintage watches. The challenge is how carefully they must be handled, which makes me nervous. So I had an idea: what if I could create something I would like that was both waterproof and robust enough for regular use? As a result, I made four prototypes for myself. My watch enthusiastic friends wanted one when I wore them out! The majority of them shared my taste and design choice for a vintage size from the past, while some wanted to gift it to their loved ones. So I made 80 pieces in each color for those who shared my taste. To me it is not important whether or not it sells, I can assure you that this watch is a good one." - Hajime Asaoka

The Kurono 34mm comes in four colour variations, each with its own strap that are colour-coordinated with the dial; White/Blue, Ochre/White, White/Red and Blue/Ivory. The 34mm features arabic numeral indexes, hour and minute hands with a luminescent finish. 

The 34mm features arabic numeral indexes, hour and minute hands with a luminescent finish.

The blue colour of the hands is IP-plated on stainless steel to prevent rusting. The box sapphire is anti-reflective coated on both sides and has an anti-fouling coating on the surface. The Kurono 34mm will come in a newly designed case, water-resistant to 5 bar.
