{"product_id":"blancpain-villeret-ultraplate-6651-3640-55b","title":"Blancpain Villeret Ultraplate 6651 3640 55B","description":"The Blancpain Villeret Ultraplate 6651-3640-55B is a masterful expression of subtle luxury and classical watchmaking. Crafted in a sleek 40 mm 18k red gold case that stands just 8.7 mm thick, it lives up to its \"Ultraplate\" name with a remarkably slim profile. The dial is a deep sunburst blue, offering a modern yet elegant contrast to the warm gold. Applied Roman numerals and delicate leaf-shaped hands echo the traditional codes of the Villeret collection, while a discreet date window at 3 o'clock adds a layer of practicality to its minimalist layout. The timepiece is completed by a blue alligator leather strap, harmonizing beautifully with the rich tones of the case and dial.\n\nInside, the watch is powered by Blancpain’s in-house automatic Caliber 1151. This ultra-thin movement, measuring just 3.25 mm thick, boasts an impressive 100-hour power reserve, made possible by its twin mainspring barrels. A silicon balance spring enhances both durability and precision, while traditional hand-finishing techniques—such as Geneva stripes, polished bevels, and perlage—are visible through the sapphire case back. With understated elegance and high-performance mechanics, the 6651-3640-55B is a refined choice for collectors who value sophistication and tradition in equal measure.","brand":"deBoulle Diamond \u0026 Jewelry","offers":[{"title":"Default Title","offer_id":50587420557614,"sku":"6651 3640 55B","price":26900.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0840\/3907\/4094\/files\/58828.png?v=1759251591","url":"https:\/\/deboulle.com\/products\/blancpain-villeret-ultraplate-6651-3640-55b","provider":"deBoulle Diamond \u0026 Jewelry","version":"1.0","type":"link"}
