An aero engine and its propeller. Each cylinder is turned on a 7-axis CNC lathe: the part is perfect as it comes off the machine. The heads receive the chosen finish. The blades are flat, openworked, drilled and decorated, then bolted to the central crankcase. Desk clock in aluminium machined from solid, high-precision quartz movement, 52 × 54 cm (H × W). Limited edition of 20 numbered pieces per colour. Designed, machined and assembled by hand in the B.R.M Chronographes workshop, France. 10-year warranty. Bespoke colours, engraving or logo available.
