Case & Bracelet

• Material & Gem‑Set Design: The 39 mm case, bezel, and integrated bracelet are crafted from 18 ct yellow gold and adorned with a total of 1,528 brilliant-cut yellow sapphires: 138 on the case (~2.76 ct), 422 on the dial (~1.84 ct), and 968 on the bracelet (~5.81 ct) .
• Finish & Wearability: Measuring just 8.1 mm thick and rated to 20 m water resistance, it stays true to the Jumbo’s elegant profile. A glare‑proofed sapphire crystal on both sides enhances daily wearability.

Dial & Visual Harmony

The dial is entirely covered in yellow sapphires, continuing the radiant aesthetic seamlessly into the heart of the watch. Applied yellow-gold hour markers and Royal Oak hands with luminescent fill ensure legibility without detracting from the gem-set display.

Movement – Calibre 7121

• Innovation & Performance: Powered by the in-house ultra-thin self-winding Calibre 7121, unveiled in 2022, the watch delivers hours, minutes, and date with a 55–52 hour power reserve at 4 Hz.
