With chronograph readings right to one-fifth of a second, the minutes scale choices 300 markers, little doubt explaining why the AB/AUF power reserve indicator didn’t make the cut back.

The hour and minute palms are inlaid with lume, and the central chronograph seconds hand is coated from tip to toe.

Every the sub-dials – subsidiary seconds at 9 o’clock with the day of the week and day/night indicator and 30-minute elapsed events at 3 o’clock with month and intercalary 12 months – are completely lumed.
