Charlie Paris GRX Gamma turns its entire green dial into a luminous surface

The GRX Gamma’s defining feature is a green dial made entirely luminous with Berlaglow pigment. Black raised numerals and hands reverse the usual day-night contrast, while two registers, a date and 24-hour display give the field-watch layout a chronograph function. The black-PVD case and green strap keep the palette tightly controlled.

The 316L steel case measures 39 mm across, 45 mm lug to lug and 10.9 mm thick before its domed sapphire. Seiko’s VK64 mecaquartz calibre combines quartz timekeeping with a chronograph seconds hand that advances five times per second. The watch is assembled in France, rated to 10 ATM or 100 metres, and fitted with an interchangeable strap.
