{"product_id":"breguet-classique-tourbillon-as12793","title":"Breguet Classique Tourbillon","description":"\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThere are complications associated with particular watchmakers, and then there is the tourbillon and Abraham-Louis Breguet. Patented by Breguet in 1801, the rotating regulating organ was conceived to counteract the effects of gravity on a pocket watch's escapement. More than two centuries later, it remains one of mechanical watchmaking’s most celebrated complications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe Classique Tourbillon Ref. 3657BA\/12\/9V6 places that invention at the center of a watch that is unmistakably Breguet. Its 39mm 18K yellow-gold case features the manufacture’s familiar fluted caseband and straight welded lugs, framing a solid-gold dial that has been silvered and decorated by hand with multiple guilloché patterns.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eA tremendous amount is happening on that dial, but the organization is remarkably graceful. The off-center time display at 12 o’clock features Roman numerals and thermally blued, open-tipped Breguet hands. At 9 sits a sector-shaped power-reserve indicator, balanced at 3 by a distinctive 24-hour day\/night display marked Heures Diurnes. And at 6 o’clock, occupying the most prominent position of all, is the exposed one-minute tourbillon, its rotating carriage also carrying the running-seconds indication.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003ePowering it is the manually wound Calibre 560.1, operating at a traditional 18,000 vibrations per hour and offering roughly 50 hours of power reserve. The movement incorporates a Breguet overcoil hairspring and extensive hand finishing, while the sapphire exhibition caseback reveals an elaborately engraved movement architecture that is every bit as decorative as the dial.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThat relationship between mechanics and decoration is really the point. The 3657 is complicated without being technical or ornate, yet retains its sense of order. Guilloché isn’t merely decoration here; different patterns help visually separate each indication, turning a potentially crowded display into something remarkably coherent.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis example is paired with a black alligator leather strap and a signed 18K yellow-gold deployant clasp. It is accompanied by its inner and outer boxes, and a Certificate of Origin from the 2010s.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eFor all its additional indications, the star remains exactly where it should be: at 6 o’clock, turning once every minute. More than 200 years after Breguet patented the tourbillon, few watches make a more convincing argument for why his invention still matters.\u003c\/span\u003e\u003cb id=\"docs-internal-guid-e9b5963c-7fff-c2af-f8c9-ef9ed9a8668f\"\u003e\u003c\/b\u003e\u003c\/p\u003e","brand":"Breguet","offers":[{"title":"Default Title","offer_id":44271620915287,"sku":"40993530","price":65500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/1255\/files\/AS12793_40993530_BREGUET_CLASSIQUETOURBILLON_3657BA-12-9V6-5.jpg?v=1790083512","url":"https:\/\/www.analogshift.com\/products\/breguet-classique-tourbillon-as12793","provider":"Analog:Shift","version":"1.0","type":"link"}
