Reading the dial can be a little confusing at first if you don't know what you're looking at. The hours and minutes are pretty obvious (or at least obvious if you've seen a Ressence watch before), but then there are two other indicators to account for. The first is a gauge that measures the temperature of the oil in the watch. This works on the expansion and contraction of the oil and shows the safe operating temperature range for the watch (-10/+40 °C). Then there's something that looks like a running seconds display – this actually makes a full rotation every 90 seconds and is there to show that the watch is running (an ISO requirement for a true dive watch). It also has some fins built into the underside that act as a shock absorber, making sure that the discs in the oil-filled top chamber don't become decoupled from the magnets in the bottom chamber on impact.
