The power reserve indicates the functioning time of a mechanical movement without it needing to be rewound. When it is worn, the watch winds itself constantly thanks to a self-winding, automatic movement. The display of the power reserve is represented by an auxiliary dial or indicator, usually inspired by a gauge for RESERVOIR watches. The level of the power reserve is mentioned by the position of the hand on the power reserve indicator. The horizontal line in the last zone of the power reserve indicator shows the power reserve is exhausted, and the watch may lose its precision. In that case, it is recommended to wind the watch manually for around 15 rotations of the crown (clockwise) to ensure the best possible rate from the outset.

The luminosity of RESERVOIR watch’s dial and hands come from a Super-LumiNova treatment. Only some models from the collections are equipped with this treatment. It works like a light accumulator, charged by the light received, it restores it over time. The Super-LumiNova material is a luminous paste composed of strontium aluminate that allows to store the luminosity from daylight or any artificial source of light and then reflect it when immersed in darkness. This treatment allows a better readability in the dark or underwater. The Super-LumiNova does not degrade over time, but the intensity and duration of the luminosity may vary depending on the time of exposure to the source of light.

The RESERVOIR watch is delivered with a standard-sized strap that fit the majority of people. For instance, a 125/75mm length with 22/20mm width suitable for 43mm cases or a 115/75mm length with 20/18mm width suitable for 39 or 41.5mm cases. The stainless steel strap can be resized to suit most wrists, this operation being offered by any official RESERVOIR stores. For the HYDROSPHERE collection, each stainless steel strap features an extension system to allow wearing the watch over a diving suit. Regarding the additional NATO strap delivered, two quick-release spring bars are delivered which ease the strap change.

However, it is never good to leave a watch in its case for a long time without using it, because it can dry the oils and therefore disturb the internal mechanism. It is therefore preferable when you are not wearing your watch, to use a watch winder. A watch winder will rotate the watch on itself, so as to mimic the movement of a wrist, in order to drive the internal rotor that keeps the watch on time. No matter where you want to store your watch, the place must not be too wet (bathroom) or too dry.
