The watch includes chronograph, moon phase, day, month, date (indicated via a central half-moon tipped hand), and a 24-hour indicator. It is powered by the automatic calibre L687, with a monocrystalline silicon balance spring and approximately 66 hours of power reserve. Water resistance is rated at 3 bar (30 m). It is delivered on a stainless steel bracelet with a triple safety folding clasp and push-piece opening mechanism.
