The PRIMA is its first word in the present tense — and a deliberate one. Co-owners Yvan Ketterer and Leopoldo Celi have resisted the easy re-edition, instead taking the brand's 1928 jump-hour as a starting point and building a form watch around it that feels closer to Streamline Moderne than to costume nostalgia.\u003c\/p\u003e\n\u003cp\u003eThe reason to take it seriously is the NHS01. A shaped, hand-wound caliber developed specifically for this case, it carries both the Geneva Seal and ISO 3159 chronometer certification — a pairing no independent has ever managed at launch — and hides its construction beautifully, with bridge screws relocated to the flanks and rhodium-plated bridges that read as a single uninterrupted surface. The display is pure regulator logic: a jumping digital hour, a rotating minute disc, running seconds at six, each hour change marked by a soft mechanical tack from a gong soldered into the case. At 7.9mm it wears as a genuine dress watch. Among the recent wave of jump-hours, it is the rare one with the provenance and the chronometry to back the concept.\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCase: Rose gold or platinum, alternating satin and polished surfaces; 27mm × 35.5mm, 42mm lug-to-lug, 7.9mm thick; anti-reflective sapphire crystal; 3 ATM\u003c\/li\u003e\n\u003cli\u003eMovement: In-house hand-wound caliber NHS01, a rounded-rectangular form movement built to the case; production-spec finishing with rhodium-plated bridges over German silver, guilloché striping, and hidden (relocated) bridge screws for an unblemished bridge surface\u003c\/li\u003e\n\u003cli\u003eCertification: Poinçon de Genève (Geneva Seal) and ISO 3159 chronometer — Niton is the first independent to launch with both distinctions in place\u003c\/li\u003e\n\u003cli\u003eDisplay: Niton's 1928-derived jump-hour \"totem\" — digital hour aperture at 12, central rotating minute disc, sweeping small seconds at 6\u003c\/li\u003e\n\u003cli\u003eComplications: Sonnerie au passage (a discreet strike at each hour jump via hammer and hand-soldered copper gong) and stop-to-zero seconds for precise setting\u003c\/li\u003e\n\u003cli\u003eCaliber spec: 72-hour minimum power reserve; 4 Hz \/ 28,800 vph; Swiss lever escapement, variable-inertia balance, Breguet overcoil hairspring\u003c\/li\u003e\n\u003cli\u003eDial: Constructed (not printed) dial matched to the case metal with a brass base, applied blue metallic hour numerals and markers, azuré minute disc; no logo\u003c\/li\u003e\n\u003cli\u003eStrap: Grained calf strap with matching precious-metal pin buckle\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Niton","offers":[{"title":"Default Title","offer_id":45524239941811,"sku":null,"price":65000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/0623\/8643\/files\/NitonPRIMASignaturePT-Front.jpg?v=1779299549","url":"https:\/\/collectivehorology.com\/products\/niton-prima-platinum-limited-availability","provider":"Collective Horology","version":"1.0","type":"link"}
