CBW218B.FT8124Ref

Introduced in 2025 as one of four Monaco Split-Seconds concept variants, the 30-piece limited 'Air' CBW218B.FT8124 features a square 41mm grade-5 titanium case (polished/brushed, crown left, pushers right), anti-reflective sapphire crystal, screwed sapphire caseback, and a fully openworked dial revealing the split-seconds mechanism from both sides. The self-winding calibre TH81-00, developed with Vaucher and beating at 28,800 vph with ~65h reserve, has the majority of its split-seconds hardware on the dial side and a partially skeletonised oscillating weight; the 'Air' variant uses blue components. It shows hours, minutes, two central chronograph hands, a 30-minute counter at 3, running seconds at 6, and tachymeter/chronograph scales on a transparent layer, and is fitted with an integrated fabric-textured rubber strap and titanium folding clasp.
