The 7255 introduces Breguet’s first-ever “flying tourbillon”, a feat of engineering where the rotating cage is suspended from below, eliminating the upper bridge for an illusion of weightlessness. But Breguet didn’t stop there. By integrating a “mysterious” complication, the brand renders the tourbillon’s mechanical linkages invisible. Sapphire glass with anti-reflective coating hides the lower support, creating the mesmerising effect of a mechanism floating in space – a nod to the word tourbillon’s original astronomical meaning: “A system of rotating celestial bodies.”
For the first time, Breguet crafts a dial from aventurine enamel, its deep blue hue scattered with copper particles that mimic a starry night sky. Each dial is fired at over 800°C in five delicate layers, ensuring no two are alike. This technique, dating to 17th-century Murano glassmakers, mirrors the unpredictability of the cosmos – fitting for a watch named Sidéral (stellar). The aventurine pairs with 18k Breguet gold appliqués, including the brand’s iconic “Breguet” numerals and hollowed apple hands, while the raised tourbillon cage protrudes 2.2 mm above the dial, emphasizing its dominance.
