During this year’s Geneva Watch Days, Swiss watchmaker, Arnold & Son, revealed its reimagined DSTB 42 collection, standing for “Dial-Side True Beat” — an ode to the brand’s historical attachment to marine chronometers, with the DSTB 42 representing both technical prowess and artistic craftsmanship.
Central to the DSTB 42 is its true-beat seconds mechanism, an uncommon feature that allows the sweep-second hand to jump from one second to another. Designed by the brand’s master watchmakers, the mechanism resembles an escapement, ensuring precision and uniqueness.
In a nod to its significance, the true-beat seconds are displayed prominently on the dial side, adding depth to the calibre, made possible with three meticulously crafted bridges. The DSTB 42 comes in two variants, one in red gold and one in platinum, both accompanied by an off-centered white opal hour dial.
Beyond the bridges lies the aesthetic anchor-shaped counterpoise, another nod to Arnold & Son’s maritime heritage. This element captures attention as it rhythmically moves up and down, governing the large seconds hand.
Notable changes include a reduced case size, from the original 44mm diameter and 7.40mm caliber thickness to 42mm and a caliber A&S6203 thickness of 5.54mm — which despite its reduction in size boasts an improved 55-hour power reserve.
In terms of aesthetics, the red gold version features a 5N gold case with a blue PVD-treated dial. On the other hand, the DSTB 42 Platinum stands out with its 950 platinum case complemented by a rose-gold PVD-treated dial. Both versions sport sunray-brushed dials, their finishing originating from the center of the true-beat seconds.
Powering these masterpieces is the caliber A&S6203, exclusively developed and assembled by Arnold & Son Manufacture. This self-winding caliber, energized by a 22-karat gold oscillating weight, operates at 28,800 vibrations per hour and ensures a commendable 55-hour power reserve.
These latest DSTB’s from Arnold & Son are set to release as limited editions, with 88 examples in red gold and 38 in platinum, priced at $48,330 USD and $61,720 USD respectively. Inquires into availability can be placed via the watchmaker’s official site or through authorized retailers.
Elsewhere in watches, Jaeger-LeCoultre offers the Polaris Chronograph in two new dial colors.
