Unlike regular watches with an hour indicator displayed via a hand circling the dial, this watch displays the hour via a window located beneath the 12 o'clock position. The hour indication "jumps" forward as the minute hand passes the 60 minute mark - hence the term "JUMP HOUR".
Retrograde: Rather than the hand rotating in continuous forward moving circles only, the hand travels along an arc, once the hand reaches the end of its journey it will spring back to the start. The following are retrograde indications:
Minute hand - main sub-dial, located towards the top of the dial.
Date indicator - secondary & smaller sub-dial located towards the bottom of the dial.
Chronograph hour & minute Sub-dial counters (right & left side of the dial).
Large central seconds hand counter.
30 minute counter sub-dial located to the right side of the dial.
12 hour counter sub-dial located to the left side of the dial.
