Polished steel studs that indicate hours are then followed by alternating gray or black/silver rings that culminate in a detailed tachymeter scale at the edge. 

A high-polish steel surround features a date window in contrasting white with black numerals.

At '3' and '9' are contrasting elapsed time and seconds subdials respectively, finished in a concentric guilloche pattern, with the elapsed-time subdial at '9' set with a uniquely designed high-polished subhand in the shape of a traditional Japanese 'kyudo' arrow.

細部には鏡面仕上げが施され、文字盤の立体感を演出しています。例として、12時位置のバーインデックス、ミニッツドット、日付表示の枠、インダイヤルの外周のリングが挙げられます。また、クロノグラフの針は全て異なる形状をしています。

The principles of kyudo archery are sometimes summarised as ‘truth, goodness and beauty’, where truth relates to shooting with a pure mind, goodness to a person’s character, and beauty to gracefulness and the refined etiquette of kyudo.

For the Chronograph 1, Hajime chose the mechanical chronograph calibre NE86A from one of Japan's most esteemed movement manufactures - positioned by them as its newest flagship chronograph movement and successor to the 6S.

Touted by the manufacturer as a premium caliber, the 311-part movement combines traditional chronograph features like a column wheel, vertical clutch, and a magic lever winding system - with a unique three-pointed hammer system that starts, stops, and resets all three wheels simultaneously. This allows for all the counters to advance continuously rather than only at one-minute intervals.

Additionally, instead of driving the minute and hour counters from the chronograph seconds wheel, each is driven by a powered wheel with its own clutch. This delivers increased accuracy and longer-term durability. The watch measures 38mm excluding the crown/pushers, and has a power reserve of 45 hours.

駆動方式は垂直クラッチで、コラムホイールを搭載した安定性のあるムーブメントです。パワーリザーブは45時間です。

The new chronograph retains the key elements of the high-polished steel case and hands that KURONO is renowned for - and more importantly - also features the unique box-sapphire watch glass so as to leverage its higher refractive and magnification performance for enhancement to lightplay.

Taken as a whole, the entire effect of the design is a breathtaking link between modern watch design and the romanticism of classical dial layouts. As the first chronograph by KURONO, considerable care and time has been put into the design and overall look-and-feel by Hajime Asaoka, and aims to achieve sophistication through simplicity. The Chronograph 1 takes the promise of 'a well-priced, well-made watch' and brings it to a whole new level aesthetically.
