The Breguet Classique Tourbillon Extra-Plat Ref. 5377BR/12/9WU in 18K rose gold unites timeless elegance with groundbreaking horology.
Exquisite 18K Rose Gold Case
The Breguet Classique Tourbillon Extra-Plat Ref. 5377 in 18K rose gold is a true masterpiece of horological artistry, embodying the Maison’s dedication to tradition and precision. The round 37 mm case is meticulously polished, highlighting the warm luster of rose gold, and its elegantly thin profile of just 3 mm thickness makes it one of the slimmest tourbillon watches in the world. The slender silhouette allows it to sit comfortably under a cuff while still making a statement of sophistication.
Iconic Breguet Craftsmanship
From the perfectly fluted caseband to the finely engraved details, every element of this watch reflects Breguet’s centuries-old design language. The lugs, measuring 21 mm between horns, are curved to ensure a perfect fit on the wrist. The non-screwed crown, also in rose gold, is engraved with the Breguet “B” and is ergonomically shaped for smooth manual adjustment.
Sapphire Caseback Transparency
Turning the watch over reveals a sapphire crystal caseback, offering a breathtaking view of the intricate mechanical movement. The transparent back showcases the hand-finished bridges, the oscillating peripheral rotor, and the visible tourbillon mechanism, all of which are meticulously decorated by Breguet’s master artisans.
Elegant Silvery Dial
The dial features a silvery finish with Breguet’s signature guilloché patterns, executed using age-old engine-turning techniques. The surface shimmers softly in changing light, enhancing legibility while adding depth and texture. The subtle layout includes an off-centre petite seconde placed directly on the tourbillon axis, a signature complication that reinforces the technical mastery within.
Distinctive Breguet Hands
The blued steel Breguet “hollow apple” hands add a vivid touch of colour to the otherwise refined dial. These hands are thermally blued for durability and aesthetic appeal, gliding smoothly across the guilloché surface. The precise shape ensures perfect readability while remaining faithful to Breguet’s heritage.
Tourbillon Excellence
At the heart of the dial lies the one-minute tourbillon—a horological marvel invented by Abraham-Louis Breguet himself. This tourbillon not only improves precision by counteracting gravitational effects but also serves as a dynamic focal point. Its finely polished cage and the petite seconds hand integrated into its axis exemplify technical innovation and visual balance.
Exceptional Mechanical Movement
Inside, the watch is powered by a peripheral automatic movement, allowing for an ultra-thin case profile without compromising performance. The calibre beats at a high frequency of 4 Hz and features 42 jewels to reduce friction and increase longevity. The use of a flat silicon balance spring ensures greater resistance to temperature variations and magnetic interference, enhancing accuracy.
Impressive Power Reserve
Despite its slim construction, the Breguet Classique Tourbillon Extra-Plat 5377 offers a generous 80-hour power reserve, allowing it to keep perfect time for more than three days without winding. This is a remarkable achievement in watchmaking engineering, particularly for such a thin tourbillon calibre.
The watch is paired with a hand-stitched black alligator leather strap, chosen for its durability and luxurious texture. Secured by a three-blade deployant clasp in rose gold, the strap ensures both comfort and safety, perfectly complementing the refined nature of the timepiece.
A Symbol of Timeless Elegance
Combining Breguet’s historic innovations, modern material advancements, and timeless design, the Classique Tourbillon Extra-Plat Ref. 5377 in rose gold stands as a testament to the Maison’s enduring legacy. This is not merely a watch—it is a wearable work of art that bridges centuries of fine watchmaking tradition with cutting-edge horological mastery.
