The Bianchet B1.618 Grande Date in its azure iteration represents cutting-edge horology with a refreshing aesthetic. This contemporary timepiece features a 44mm tonneau-shaped case crafted from lightweight carbon fibre composite, with striking blue accents that create a sophisticated, technical appearance. The openworked dial showcases an intricate architectural design, with a complex web-like structure revealing the movement beneath. The prominent grande date display at 12 o'clock offers excellent legibility, while blue-accented hands and markers provide elegant contrast against the dark mechanical backdrop. The symmetrical skeleton design creates an engaging sense of depth and mechanical intrigue. At its heart beats a hand-wound mechanical movement, featuring the sophisticated grande date complication and delivering an impressive 90-hour power reserve. The movement's contemporary finishing, visible through both the dial and sapphire crystal caseback, complements the watch's modern design language. Water-resistant to 100 metres, the timepiece is fitted with a light blue technical fabric strap with black rubber inserts, secured by a carbon fibre buckle.
