2018 marks 240 years since the creation of John Arnold's historically significant Chronometer No. 1/36, the first time-measuring instrument to be called a "chronometer" for its unprecedented precision. To mark the historical milestone, Arnold & Son is proud to introduce a modern homage edition of the Tourbillon Chronometer No.36, a COSC-certified Tourbillon wristwatch.
