Inside the automatic Khaki Navy Regatta is a slightly modified Valjoux 7750 chronograph movement, mounted ‘up-side-down’. It has the crown to set the time at 9 o’clock, two more crowns to adjust the upper and lower interior rotating bezels, and two pushers for the countdown function. One pusher at 8 o’clock for start/stop and one pusher at 10 o’clock for reset. In the 6 o’clock subdial both a 3/6 minutes as a 5/10 minutes countdown are visualized with little coloured dots. In stead of a hand, this subdial has a coloured indicator disk underneath.

How it Works

After a reset all little dots colour yellow/red. When the chrono is activated the countdown starts and the sweep hand is set in motion (no countdown scale for the seconds). Like a minute hand, the indicator disk jumps one postion after one minute changing the color of a yellow dot into red, and one red dot into blue. And so gradually all dots change color every minute. At the start of the regatta all dots are blue. Unless you push the stop pusher, the indicator disk doesn’t stop revolving
