Jaeger-LeCoultre Q1682401 Master Ultra Thin Tourbillon Pink Gold Diamond Eggshell Dial Watch

Jaeger-LeCoultre Master Ultra Thin Tourbillon – Ref. Q1682401

The Jaeger-LeCoultre Master Ultra Thin Tourbillon Ref. Q1682401 is an exquisite expression of haute horlogerie that merges technical artistry with refined elegance. Crafted in 18-carat pink gold and framed by a diamond-set bezel, this 40 mm masterpiece is built around a mesmerising tourbillon at 6 o’clock. With its slender profile, open caseback, and rich eggshell beige dial, this timepiece epitomises both dress luxury and mechanical mastery.

Case Bezel: Gold Luxury Meets Diamond Brilliance

The case is fashioned from 750/1000 18-carat pink gold, measuring 40 mm in diameter and about 10.7 mm thick. Surrounding the bezel are carefully selected diamonds (≈ 68 stones) that not only enhance sparkle but frame the dial with elegance. Water resistance is rated at 5 bar (≈ 50 meters), adequate for splashes and everyday wear. The sapphire crystal protects both front and back—offering visibility of the breathtaking tourbillon and movement finishing.

Dial Display: Subtle Warmth Mechanical Drama

Underlying the bezel, the eggshell beige dial imparts a soft, warm palette that complements the pink gold case. At 6 o’clock, an aperture reveals the tourbillon, dancing with precision beneath a new gold bridge—a design element introduced to enhance visual continuity and prestige. Dauphine hands and applied baton indices complete the classic layout, emphasizing legibility. Seconds display is handled via the tourbillon’s rotation; minutes and hours marked cleanly.

Movement: Calibre 978G – Precision Power

Inside the Q1682401 pulses the in-house Jaeger-LeCoultre Calibre 978G, an automatic self-winding movement built for both beauty and performance. It features approximately 271 components and 33 jewels, beating at 28,800 vph (4 Hz). The movement is about 6.5 mm thick, and the entire watch offers a 45-hour power reserve. Through the transparent caseback, one can observe fine finishing—the Geneva stripes, polished bevels, and the architecture that supports the tourbillon.

Strap, Buckle Comfort Features

Q1682401 is supplied with a high-quality alligator leather strap—typically brown—that harmonizes with the warmth of the gold and eggshell dial. The strap is interchangeable and fitted with a double-folding pink gold buckle. Lug width is 21 mm, with standard lengths at 75 mm at the 12-o’clock side and 120 mm on the 6-o’clock side, ensuring a comfortable fit for many wrist sizes without overwhelming the wrist.
