The TSD Rally Split consists of two clocks with different purposes. Master•Time on the left is the rally time-of-day clock. This clock can be adjusted to synchronize with the Official Rally Time clock. Also, the Master•Time clock can be stopped by touching the button on the left side. Retouching the button will cause the digital clock display to resume tracking time-of-day.

Monte•Carlo on the right is a stopwatch with two buttons: one starts and resumes the stopwatch and the other records each lap.

When the stopwatch has been stopped, there are two options for resetting it to zero after the stopwatch. One option is to reset to zero upon clicking the rightmost button beneath the stopwatch. The other option is to have the stopwatch reset when the time-of-day clock begins the next minute.

Touching the "Adjust" button opens a popup that allows you to synchronize the Master•Time to the Official Rally Time by making adjustments in increments of +/– 0.1 seconds to account for total errors of as much as + or – 10 seconds.

Touch the Lock button to make clock adjustments. Adjust time ahead or behind as needed and, when finished, touch the Unlock button to prevent unintended adjustments. Touch the double Arrows singly or continuously to make adjustments in +/– 0.1 second increments.

When unlocked, a chime will sound at 0 seconds and 30 seconds. This audible cue is helpful when synching with an Official Clock.

When the Official Rally Clock’s second hand reaches zero, the start of a new minute, estimate the error by which your clock is behind or ahead of the Official time and add or subtract 0.1 second increments.

On the clockface displays, time can be measured in either seconds or decimal minutes. Additionally, there are two levels of time precision. One displays two digits for seconds or two digits for hundredths of a minute. For more precision, the other measures and displays seconds as two digits plus tenths of a second or three digits for thousandths of a minute.

There are three watch face styles: black, yellow, and white.
