Description
The Heritage Sector Chronograph Aventurine combines the clarity of a classic sector chronograph with the poetic depth of aventurine glass.
Its deep blue dial is filled with countless shimmering particles, catching the light like a night sky and shifting from subtle sparkle to a vivid starfield with each movement of the wrist. Yet beyond its visual effect, this is a highly complex aventurine execution.
To create the recessed chronograph counters and multi-level architecture, the dial is built on a rigid brass base and topped with two identical aventurine layers. These layers are carefully matched, bonded, and precisely aligned, allowing the beauty of aventurine glass to be combined with the dimensional structure required for a true chronograph dial.
The sector layout brings balance and legibility, with concentric scales, crisp numerals, and an instrument-style minute track. In low light, BGW9 Super-LumiNova illuminates the hour and minute hands, numerals, and sector print, preserving the structure of the dial after dark.
Poetic in daylight and uncompromisingly legible at night, the Heritage Sector Chronograph Aventurine transforms stardust suspended in glass into a fully functional chronograph.
Supplied by the brand to the GPHG for its entry.
