Inspired by George Graham’s 18th-century watchmaking legacy, the PS Horology Tsuba 1720 combines historical inspiration with contemporary precision. Its 38.3mm stainless steel case, measuring just 8.91mm thick, houses the Swiss-made Vaucher Manufacture calibre 5401 automatic movement. Featuring an ultra-thin 2.60mm movement with a personalised tungsten micro-rotor, the watch delivers a 48-hour power reserve and operates at 21,600 vibrations per hour. Sapphire crystals on both sides and 3 ATM water resistance complete the case, while the redesigned stainless steel bracelet offers articulating first links, concealed adjustment and a butterfly deployant clasp with push-button release. Limited to just 28 pieces, the Tsuba 1720 brings together horological heritage, refined proportions and mechanical sophistication.
