"Most GMT watches fall in the sports watch category. However, those who genuinely desire the GMT complication are business travelers. I wanted to incorporate tradition while at the same time reflect a sense of coordinated modernity. With this in mind, the Kurono GMT 1 is designed to complement the cuffs of the globetrotting executive in an intellectual manner." ~ Hajime Asaoka.

Introducing the new limited

Kurono GMT 1

Kurono Tokyo is proud to present our first world-time complication - the Kurono GMT 1 - a new novelty and design study by master Japanese watchmaker Hajime Asaoka.

The new Kurono GMT 1 imbues Hajime Asaoka's strong art-deco design language coordinated with intelligent gentility. Hajime Asaoka set out to design a watch for the business traveler that would coordinate with boardroom business attire, but yet retain a sense of understated sportiness.

The Kurono GMT 1 is a true GMT watch that has been nominated as a finalist for the 2023 Grand Prix d'Horlogerie de Genève Awards under the 'Challenge' category.

"Business fashion remains conservative, with fine haberdashery trends in suits and shoes seeing only minute changes through the decades. Kurono Tokyo contemplates designs that incorporate tradition with a heightened awareness of the contemporary, particularly in coordinating timepiece styles that transcend trends. Specifically, by designing a dial with a restrained diameter of 38mm, Kurono seeks the beauty and elegance of a watch that naturally fits under-the-cuff."

The complication adopted for the GMT 1 is a "True GMT," where instead of adjusting the 24-hour hand, the local hour hand can be independently adjusted in one-hour increments forward and backward, with date changes up or down in tow. This enables quick responses when there is a need to change time zones.

The addition of the bi-directional bezel allows for a myriad of possible timekeeping uses apart from a third-time zone. Furthermore, considering durability, this rotating bezel has been carefully chosen to be clickless with a specific tension for ease of usage.

The Kurono GMT 1 retains the curved Kurono 38mm high-polish case with the addition of the glazed bi-directional rotating bezel. It features lacquer-filled 24-hour markers, as well as the now iconic art-deco concentric lines that serve as a day-night indicator. Thematic coordination is brought to the dial via contrasting black, gray, and crimson dial rings - each demarcating the various time and time-zone functions of the watch.

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. A 24 hour arrow hand is in red filled with superluminova.
