Kurono Tokyo Calendrier 'Type I'

The Kurono Calendrier 'Type I' is a complete calendar watch with a classic coin-edged bezel that ushers in a new design language by master watchmaker Hajime Asaoka - designed for the gentleman adventurer but still firmly rooted in his penchant for the vintage romanticism of the art-deco era.

Its design intent is for it to be worn regularly and to develop character over time - a design that allows for and embraces scratches. "Blemishes accumulated are unique to the wearer and is a written record of his journey and adventures through life. Owners should spend their time in meaningful pursuits rather than worry about scratches. Hence the design embraces such blemishes, adds character, and looks better over time," said Hajime Asaoka.

The design of the Calendrier 'Type I' has been calculated to enhance the three-dimensionality of the iconic Kurono hands and the symmetry of the dial. It aims to evoke a sense of refined adventure - with its new high-polish coin edge bezel and khaki dial interplaying with an audacious blacklettered vintage typeface to evoke a bold regimental atmosphere for the wrist. Guilloche sub-dials with high-polish hands hint at the mechanical complexity of its triple calendar complication, with the mood accentuated by railway-track minute markers at the periphery.


The Kurono Calendrier 'Type 1' is a watch designed by renowned Japanese watchmaker Hajime Asaoka, who was inspired by a casual conversation over drinks with a watch collector: "If you had to live on an isolated island, what would you take with you?" His book-loving friend said a novel by Haruki Murakami. Mr. Asaoka answered: "A watch," and he began to think about the functions that such a watch would need.

Time is the most basic determinant for modern life, and the full calendar is the embodiment of this importance. I believe that wearing a watch in our daily lives will bring us closer to the idea of valuing time.


The Kurono Calendrier 'Type I's dial enhances the "beauty of symmetry" that is a component of the Art Deco style. The cylinder dial is designed to curve from the center to the outer edge of the dial, and two dial layers are pressed together to create a three-dimensional effect. The numerals themselves are also purposefully printed in a raised format.


The combination of high-polish leaf hands for the hour and minute hands with modern hands is a typical Kurono design. The hour and minute hands are curved at both ends, and are paired with a counterweighted second hand that is very thin. The tips of the second and minute hands are bent by hand.


The case is made of forged 316L stainless steel. It is newly designed to fit the coin-edged bezel, but keeps the iconic Kurono case DNA. The case sides are mirror-finished. The mirror finish is free from distortion, so much so that exterior reflections are beautifully portrayed. Also, when viewed from the side, the mirror finish and the coin-edge bezel can be seen to stand out in their respective finishes. Water resistance has been increased to 5 ATM. The case-back is finished with a circular lettering design, as seen on vintage watches.

Sapphire crystal

The scratch-resistant box sapphire crystal is raised like the acrylic glass of a vintage watch. Designed for the Calendrier 'Type I', its shape is 0.15 mm higher than that of an ordinary sapphire box crystal.

Movement made in Japan

Miyota 9122 - a Japan-made movement - is used. It is a rare movement with "center seconds and full calendar," which is uncommon in current Swiss-made mass-produced ebauches. Leveraging a Japanese movement allows for the Kurono Calendrier 'Type I' to be fully Japan made.
