Bimbu Patrium Silicium gives the stone-dial concept a technical edge

The Bimbu Patrium Silicium substitutes monocrystalline silicon for the natural-stone dials that define much of the collection. Its grey, technical surface sits inside a 39 mm Grade 5 titanium case measuring 8.8 mm thick. Sapphire crystals cover the front and back, while small seconds and baton hands preserve the clean Patrium layout.

Inside, Bimbu uses a hand-wound ETA/Peseux 7001 modified and finished with Concepto. The movement runs at 3 Hz and delivers around 42 hours of reserve. A tool-free strap attachment supports quick changes. The Swiss independent lists the Silicium from CHF 16,350, with options able to alter the final price.
