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 A&S7103 caliber is a proprietary mechanical self-winding movement with column-wheel operated chronograph. The movement is configured to give optimum balance and beauty to the dial, with off-centered hour and minutes at 12 o’clock, big central true beat seconds and central chronographs seconds, and 60-minutes chronograph indicator at 6 o’clock. The 31-jewel movement beats at 28,800 vibrations per hour and offers more than 50 hours of power reserve.

Each in-house mechanical movement is NAC grey treated and meticulously completed in Haute Horlogerie finishing with hand-chamfered bridges with polished edges, fine circular graining and Cotes de Geneve rayonnantes, brushed and skeletonised rotor, and screws with bevelled and mirror-polished heads.

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.
