Kurono Tokyo 34mm Lineup 2023

"Why 34mm?

How do you pick the clothes you will wear every morning?

For me, the first thing I do is select jackets, pants, and shirts from my wardrobe then lay them all out with socks, shoes, and other items. Finally, I place my watch there and check the entire look. I think you probably do the same. What I pay attention to when I do this is making sure that the watch alone doesn't stand out. From this perspective, I find the size of 34mm to be very desirable.

But I wonder how many people would agree with that. There is no point in making a watch if it does not sell at all. This is why I experimented with selling 34mm watches last time. We had a pop-up exhibition in Shibuya to give people an opportunity to experience how the size of 34mm looks to them. The watches were sold out quickly.
Later, when I saw the photos posted on social media such as Instagram, it seemed that people were enjoying coordinating it with their outfits. As the designer of this watch, I was very happy to see this. It was worth the effort.
Now, I made the second version of the watch in response to the favorable feedback. But this time, the color is more subtle. How would you like to match it with your outfits?" - Hajime Asaoka.
The Kurono 34mm comes in four colour variations, each with a neutral black leather strap that will match in any occasion: Darkmist, Smoke, Midnight and Persimmon.
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 comes in a newly designed case, water- resistant to 5 bar.
