Aqua Lung Hundred Hour Limited Edition
The Blancpain Léman Ultra-Slim Aqua Lung “Lemon” Hundred Hour Limited Edition is a rare and refined piece that blends the brand’s historic dive watch heritage with modern elegance. Released in a highly limited run of just 200 pieces, this watch draws inspiration from Blancpain’s iconic 1953 Fifty Fathoms—the world’s first modern dive watch developed for military use and famously linked to Jacques Cousteau’s Aqua-Lung. The watch features a sleek 38mm brushed 18k rose gold case with an ultra-thin 8.9mm profile, making it both comfortable and discreet on the wrist.

A sapphire caseback reveals the finely decorated movement and a distinctive yellow rotor—earning the watch its “Lemon” nickname. Part of the now-retired Léman collection, this limited edition stands as a sophisticated expression of Blancpain’s commitment to craftsmanship, performance, and enduring design. This watch recently received a factory service in 2025, which included a new factory strap,
