Introduced in 1961, the reference represents one of the early moments in which Patek Philippe successfully combined automatic winding, a date complication, and a water-resistant screw-back case within a restrained dress watch format.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eWhile earlier Patek Philippe wristwatches had incorporated automatic movements, the Reference 3445 helped establish the practical architecture that would later define many of the manufacture's modern time-and-date wristwatches. Its robust screw-back construction offered improved water resistance while preserving the balanced proportions and understated elegance associated with the Calatrava lineage.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe present example was produced in 1962 and is powered by the self-winding Patek Philippe Caliber 27-460M, one of the manufacture's most respected automatic movements of the period. The caliber features an 18k gold rotor engraved with the Calatrava Cross, Gyromax balance, and Geneva Seal finishing, reflecting the manufacture's commitment to mechanical refinement as well as durability.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe silvered dial is distinguished by its Gübelin retailer signature, indicating original sale through the renowned Lucerne jeweler whose longstanding partnership with Patek Philippe produced some of the most desirable double-signed dials in the vintage market. Applied gold baton hour markers and a framed date aperture at three o'clock maintain the restrained clarity typical of early 1960s Genevan watch design.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe 18k yellow gold case measures approximately 35 millimeters in diameter and retains the screw-back construction characteristic of the reference. The interior caseback is stamped \"Patek Philippe \u0026amp; Co Genève Swiss\" together with the appropriate gold hallmarks, case serial number, and the case maker's hallmark, reflecting the traditional collaborative production practices employed by the manufacture during the period.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe watch is accompanied by a Patek Philippe Extract from the Archives confirming production in 1962 and original sale on March 29 of that year.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e The watch presents attractively overall with well-preserved case proportions and a dial that retains strong legibility with balanced aging consistent with careful long-term ownership. The movement is currently undergoing service at Patek Philippe in Geneva. The watch is expected to return in fully operational condition following completion of service.\u003c\/p\u003e","brand":"WRISTORIAN","offers":[{"title":"Default Title","offer_id":47564476448938,"sku":"WRI-311.671","price":35000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0650\/1236\/7530\/files\/WEBSITE_-_Placekeeper_-_Patek_-_02.jpg?v=1770987711","url":"https:\/\/www.wristorian.com\/products\/patek-philippe-3445j-gubelin-calatrava-1962","provider":"WRISTORIAN® ","version":"1.0","type":"link"}
