Bimbu Patrium Lapis Lazuli pairs deep blue stone with snow-set diamonds

Bimbu’s Patrium Lapis Lazuli et serti Neige extends the brand’s natural-stone concept with an Afghan lapis lazuli dial and snow-set diamonds. The 39 mm Grade 5 titanium case is 8.8 mm thick, with sapphire crystals front and back. Small seconds provide an off-centre counterpoint to the stone’s naturally variable texture, making every dial visually distinct.

A Concepto-modified ETA/Peseux 7001 is wound by hand, runs at 3 Hz and offers approximately 42 hours of reserve. Bimbu also uses a tool-free strap system to encourage changes without specialist equipment. The model is listed from CHF 28,435, depending on configuration.
