Breguet 3657PT Classique Tourbillon Power Reserve Platinum Silver Dial

The Breguet 3657PT/12/9V6 Classique Tourbillon Power Reserve is a refined expression of haute horlogerie, introduced circa 2020 within Breguet’s prestigious Grandes Complications/Classique collection. Encased in 39 mm platinum, this manual‑winding masterpiece houses the caliber 515DR (also referenced as 560T in some sources), delivering a substantial 50‑hour power reserve. Its silver engine‑turned dial is elegantly offset, featuring a tourbillon at 6 o’clock with integrated seconds, a power‑reserve indicator to the left, and a retrograde 24‑hour display to the right—an uncommon and highly collectible configuration. The transparent case back reveals the exquisitely finished movement, embodying Breguet’s legacy of technical artistry and mechanical sophistication. With a water resistance of 30 meters, this timepiece is more a refined dress complication than a sports watch, reinforcing its rarity and desirability among collectors. The platinum case, paired with a black alligator strap, enhances its timeless elegance, while the manual tourbillon movement underscores its traditional craftsmanship. This reference stands as a testament to Breguet’s mastery in combining classical aesthetics with complex functionality. Like New with Breguet box and undated papers.
