unique true beat mechanism

The true-beat seconds’ function is characteristic of John Arnold’s instruments supplied to the Royal Navy. Their escapement used to beat at one oscillation per second, naturally indicated by a sweep-second hand. This explicit function inspired Arnold & Son to create one of its most iconic complications: ‘True Beat’, also known as deadbeat seconds. The distinctive feature of the DSTB collection is that it displays this mechanism in full on the dial, hence the ‘Dial-Side True Beat’ name, delivering watchmaking, design and spectacle all in one.

balanced design

The design of DSTB is truly exceptional. This is because the true-beat seconds’ mechanism needed to be displayed in a way that reflects its historical importance for Arnold & Son. It has been placed on the dial side, creating an additional level in the calibre. They are openworked, three-dimensional, and carefully crafted from red or white gold, depending on the version of DSTB. The presence of this true-beat seconds mechanism fills the space and is balanced out by the off-centred hours dial in white opal, which is another signature of Arnold & Son.
