Bell & Ross BR-X3 Tourbillon Micro-Rotor (2025)

Case is 40mm with a thickness of 9mm, three-component construction – steel middle case, sapphire top, sapphire caseback – held together by four signature screws, satin-finished and polished steel with customised bridges, sapphire crystal with AR coating, water resistant to 50m, paired with a grey alligator strap and satin-finished polished steel folding buckle. Dial is fully skeletonised with a small sapphire fumé dial, only hours and minutes displayed and offset at 2 o’clock, the movement’s square skeleton echoing the case’s geometry with straight horizontal and vertical bridge lines, 26 rubies visible throughout, brushed bridges with linear reflections and polished edges. Movement is the in-house calibre BR-CAL.389, automatic with a micro-rotor positioned within the movement plane rather than above it, flying tourbillon at 5:30 completing one rotation per minute. Power reserve is 58hrs. Limited to 25pcs. Priced at CHF 80,000
