For just US$83,660, you can match your belt buckle with your favourite ride. Folks at Geneva-based Roland Iten Mechanical Luxury collaborated with Bugatti to create the Calibre R22 Mark I Bugatti edition with the same dedicated approach towards fine watchmaking and luxury motoring. A total of 100 hand-polished components, including bridges, cogs, wheels and pinions, go into the belt buckle to allow micro adjustment to any size within a 22mm range. The complications are painstakingly designed to allow the utmost precise customisation of nothing else but your belt. All the cool mechanics are concealed under the sleek sapphire crystal hood, featuring Côtes de Genève decoration. Crafted in solid gold and titanium, the piece is limited to a series of 22 units only and is available at The Lavish Attic in Central's Pedder Building.
