No wristwatch escapement naturally beats at the rate of one oscillation per second, a frequency designed for certain large-format clocks. The A\u0026amp;S6203 calibre functions at 4 Hz or eight oscillations per second. Creating a seconds hand that jumps from one index to the next requires a dedicated mechanism, similar to an escapement. Developed in-house by Arnold \u0026amp; Son watchmakers and reserved for this collection, the mechanism is fully displayed on the dial side in tribute to the groundbreaking advances that John Arnold brought to marine chronometry.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis true-beat seconds mechanism is showcased in a manner befitting its historical importance for Arnold \u0026amp; Son. Choosing to position it on the dial side means the movement must be crossed, adding an additional level to the A\u0026amp;S6203 calibre and requiring the creation of three specific bridges. They are designed in harmony with the Arnold \u0026amp; Son style. Openwork and three-dimensional, they are crafted in solid gold.\u003c\/p\u003e\n\u003cp\u003eOn these bridges, the seconds hand follows the track stretching between 9 and 12 o’clock, providing balance opposite an off-centred hours and minutes dial in white opal at 5 o’clock. This layout reflects an intentional aesthetic choice, rather than merely a contrived offsetting of the movement, as indicated by the crown, which remains at 3 o’clock\u003c\/p\u003e","brand":"Arnold \u0026 Son","offers":[{"title":"Default Title","offer_id":49071182840052,"sku":"18880055","price":57300.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/8570\/2900\/files\/AS-DSTB-42-RG-Green_face-up_png.webp?v=1790355646","url":"https:\/\/www.watchesofswitzerland.com\/products\/arnold-son-dstb-1atcer-f01a-c1242a-18880055","provider":"Watches of Switzerland","version":"1.0","type":"link"}
