Arnold & Son Instrument CTB unveiled; world’s first chronograph with a central true beat seconds hand

Every minute takes 60 seconds but Arnold & Son’s newest ‘Instrument CTB’ timepiece feels like a celebration of every micro- second. The world’s first true beat seconds and chronograph wristwatch joins Arnold & Son’s Instrument Collection. The true beat seconds is a precision function wherein the seconds beat incrementally as opposed to sweeping along the dial – allowing for more accurate reading. The true beat seconds have been incorporated on the same axis as the chronograph seconds hand but with different jumping intervals.

The CTB represents the brand’s second chronograph and blends the iconic Instrument Collection complication of a true beat seconds, while at the same time remaining true to the line’s optic code of superb legibility.

The 44 mm stainless steel timepiece is offered with a light-grey and silvery opaline dial. The dial has a complex multi-level structure with at least three different finishes that offer breathtaking depth and dimension.

The series is inspired by the timepieces produced during the second part of John Arnold’s life when he and his son, John Roger, dedicated themselves to the quest for absolute precision.
