The movement itself is also visually upgraded — rhodium-plated bridges, openworked rotor, blue-coloured screws, and striped decoration on the main bridge, all visible through the exhibition caseback. The black sunray dial features a guilloché-style concentric pattern that adds depth and texture, and the bracelet is upgraded to a 5-link Jubilee-style design with a concealed butterfly clasp.

The Calibre 8310 delivers 60 hours of power reserve instead of 40 and looks genuinely attractive through the exhibition caseback — rhodium-plated instead of raw brass. The 5-link Jubilee bracelet with concealed butterfly clasp is a clear step up from the standard Tsuyosa's 3-link design. And the guilloché-textured dial adds visual depth that a flat sunray doesn't achieve. At $730, it costs more than the standard Tsuyosa — but the movement, bracelet, and finishing improvements justify the step up. Also available in green with gold-tone accents (NK0030-51X) and full gold-tone (NK0032-56A).\u003c\/span\u003e\u003c\/p\u003e","brand":"CITIZEN","offers":[{"title":"Default Title","offer_id":49585082761431,"sku":"NK0030-51E","price":730.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/2451\/7272\/files\/Citizen_NK0030-51E.png?v=1786677494","url":"https:\/\/www.citychain.com.sg\/products\/citizen-nk0030-51e-tsuyosa-mechanical-men-watch-1","provider":"City Chain Singapore","version":"1.0","type":"link"}
