{"product_id":"zenith","title":"Zenith","description":"\u003cp\u003eThe Zenith 28800 Automatic, powered by Calibre 2562PC, represents a pivotal era in horology: the \"High-Beat\" revolution of the late 1960s and early 1970s. During a period when standard movements vibrated at 18,000 or 21,600 beats per hour (vph), Zenith pushed it all the way to 28,800 vph. This increased frequency was supposed to offer superior rate stability and greater resistance to shocks, marking a significant leap in mechanical precision. You can see high beats in most high end watches today.\u003c\/p\u003e\n\u003cp\u003eZenith's Calibre 2562PC was a real technical marvel, featuring 23 jewels and a ball-bearing rotor that epitomised the manufacture's engineering prowess. While attention often shifts toward the legendary El Primero, the 2562PC was the reliable, high-frequency workhorse that solidified Zenith's reputation for accuracy in a daily beater (or rather high-beater!)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eTech Specs.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cstrong\u003eReference\u003c\/strong\u003e: Zenith 28,800 Automatic\u003cbr\u003e\u003cstrong\u003eYear\u003c\/strong\u003e:  c.1972\u003cbr\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e   Calibre 2562PC\u003cbr\u003e\u003cstrong\u003eService History\u003c\/strong\u003e:  unknown\u003cbr\u003e\u003cstrong\u003eDial:\u003c\/strong\u003e  Silver \u003cbr\u003e\u003cstrong\u003eMeasurements\u003c\/strong\u003e:  34mm (case diameter), 40mm lug-to-lug, 11.5mm thickness\u003cbr\u003e\u003cstrong\u003eWater Resistant:\u003c\/strong\u003e  No\u003cbr\u003e\u003cstrong\u003eCrown\u003c\/strong\u003e:  signed Zenith\u003cbr\u003e\u003cstrong\u003eStrap\/Bracelet:\u003c\/strong\u003e  Black strap, signed Zenith\u003cbr\u003e\u003cstrong\u003eLug Width\u003c\/strong\u003e:  17.5mm\u003cbr\u003e\u003cstrong\u003eBox \u0026amp; Papers\u003c\/strong\u003e: Box only (see image)\u003cbr\u003e\u003cstrong\u003eWarranty:\u003c\/strong\u003e  3 months\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003eWatches modelled on a 7” (18cms) wrist\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(2, 227, 223);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eThis lovely example has a 1972 hallmarked 9ct gold case back and is in great cosmetic (the case and dial are in wonderful shape) and working condition. It’s service history is unknown, but it is keeping good time and within vintage watch parameters. It has what might be its original strap (a little frayed near the lugs) which is staying with this watch and a Zenith buckle. It also comes with possibly its original box, which unfortunately shows signs of mould and foxing.  \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(2, 227, 223);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(2, 227, 223);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eThere are a few small scratches on the case back and case commensurate with a watch this age. \u003c\/span\u003e\u003c\/span\u003eThe case is also of interest as it is stamped DS\u0026amp;S on the inside case back. \u003c\/span\u003e\u003c\/span\u003eDavid Shackman \u0026amp; Sons (DS\u0026amp;S) were a renowned London-based manufacturing jeweller and case maker (approx. 1960–1974) known for producing high-quality gold watch cases and bracelets for luxury Swiss brands—including Rolex, Tudor, Longines, and Omega—to avoid high UK import duties.\u003c\/p\u003e","brand":"Vintage Chronicle","offers":[{"title":"Default Title","offer_id":53753145360721,"sku":"0039","price":850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1020\/4148\/5649\/files\/0039_Zenith_Automatic-1.jpg?v=1778575003","url":"https:\/\/www.vintagechronicle.co.uk\/products\/zenith","provider":"Vintage Chronicle","version":"1.0","type":"link"}
