{"product_id":"arnold-son-1atcr-u01a-c200a","title":"Arnold \u0026 Son Chronometry Dual Side True Beat 42 Red Gold 1ATCR.U01A.C200A","description":"\u003ch2\u003eThe beating heart of a new rhythm\u003c\/h2\u003e\n\u003cp\u003eThe true-beat seconds function is characteristic of the instruments that John Arnold supplied to the Royal Navy. Their escapement used to beat at one oscillation per second, naturally indicated by a sweep-seconds hand. This explicit function inspired Arnold \u0026amp; 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.\u003c\/p\u003e\n\u003cp\u003eDesign, because this true-beat seconds needed to be displayed in a way that reflects its historic importance for Arnold \u0026amp; Son. The choice to place it on the dial side creates an additional level in the calibre. This, in turn, required three dedicated bridges, fashioned in line with the Arnold \u0026amp; Son aesthetic, whose graphic design and finishes give the dial its truly unique appearance. They are openworked, three-dimensional and carefully crafted from red or white gold, depending on the DSTB 42 version. This true-beat seconds mechanism fills the space with its presence, balanced out by the off-centred hours dial in white opal.\u003c\/p\u003e\n\u003cp\u003eSpectacle, because the even, slow and aesthetic functioning of the true-beat seconds mechanism catches the eye. It symbolises both Arnold \u0026amp; Son’s watchmaking expertise and its roots, down to the anchor-shaped counterpoise reminiscent of marine chronometers. It goes up and down as the underlying calibre does its work, controlling the large seconds hand.\u003c\/p\u003e\n\u003cp\u003eThe DSTB 42 Red Gold comes in a 5N gold case, whose copper content gives it the name red gold. This warm colour is paired with a blue PVD-treated dial for a soothing overall effect. In both versions, the dial is sunray-brushed before being tinted, the starting point of the finish coinciding with the centre of the true-beat seconds.\u003c\/p\u003e\n\u003cp\u003eThe DSTB 42 is powered by the calibre A\u0026amp;S6203, which has been entirely developed, machined, assembled and adjusted in the Arnold \u0026amp; Son Manufacture. Designed to work in harmony with the true-beat seconds mechanism, this calibre is self-winding thanks to an oscillating weight in 22-carat gold. It features a 55-hour power reserve and a regulating organ oscillating at 28,800 vibrations per hour.\u003c\/p\u003e\n\u003cp\u003eThe DSTB collection was one of the founding pieces in the Arnold \u0026amp; Son catalogue. Its first version measured 44 mm in diameter. It featured a calibre that was 7.40 mm thick, allowing a 45-hour power reserve. The DSTB 42 improves on each of these points. The exclusive Manufacture calibre A\u0026amp;S6203 is 5.54 mm thick and offers 55 hours of autonomy. The case drops to 42 mm in diameter and settles for a total thickness of 12.95 mm.\u003c\/p\u003e\n\u003cp\u003eLimited to 88 pieces.\u003c\/p\u003e","brand":"Arnold \u0026 Son","offers":[{"title":"Default Title","offer_id":54826178249076,"sku":"1ATCR.U01A.C200A","price":57300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2930\/0774\/files\/arnold-son-dstb-rg-blu-topper_3d2a4ae3-8f55-4e7c-9ec5-9300c1e36d0a.png?v=1781896171","url":"https:\/\/topperjewelers.com\/products\/arnold-son-1atcr-u01a-c200a","provider":"Topper Fine Jewelers","version":"1.0","type":"link"}
