Buying a RESERVOIR Watch

  • Where can I buy a RESERVOIR watch?

    The RESERVOIR watch collections are available either in stores via a network of partner distributors or on their merchant website, or on RESERVOIR official online store
    We strongly recommend that you purchase your RESERVOIR watch through a physical store or official online.
    Only watches distributed by our authorized distributors are guaranteed to be genuine. Any watch purchased outside this network will not be covered by the international warranty.

  • How can I be sure I am buying a genuine RESERVOIR watch?

    All RESERVOIR watches sold on our official website and at our authorized retailers are authentic.
    Each RESERVOIR watch carries a unique serial number engraved on the case back : the combination of this serial number with the reference number allow the authentification of the watch.


  • What is an automatic movement?

    An automatic movement, often referred as “self-winding” is a mechanical watch movement that is wound by the natural motion of the wearer’s wrist. An oscillating weight (rotor) pivots freely around a spindle, and each movement of the wrist helps to wind the mainspring (energy source),and automatically charging the power reserve.

    If the timepiece is worn every day, the owner will not have to wind the watch by-hand to keep it operational and accurate.

    An automatic movement is the ultimate example of Swiss watchmaking expertise and tradition.

  • What is the value of RESERVOIR watches?

    RESERVOIR watches are handmade in Switzerland at La Chaux-deFonds, in compliance with traditional craftsmanship and “Swiss made” label.

    All RESERVOIR watches feature three watchmaking complications : a retrograde minute hand, a jumping hour and a 37-hours power reserve.
    In order to fine-tune the precision mechanism so that the three complications on the timepieces can be displayed, a 124-components proprietary watchmaking module has, to this end, been specially drawn up and patented. The module is powered by a Swiss Made ETA 2824-2 movement, widely acclaimed for its reliability and precision, oscillating at 28,800 alt./h.

    All models are granted with an international warranty of 3 years.

  • Where can I find serial number for my RESERVOIR watch ?

    The serial number of your RESERVOIR watch is engraved on the case back at the 6 o’clock end.

  • What is the power reserve for a self-winding mechanical RESERVOIR watch and how does it work?

    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, or automatic movement.

    You can see the level of the power reserve thanks to 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, we recommend you wind the watch manually for around 15 rotations of the crown (clockwise) to ensure the best possible rate from the outset.

    The power reserve indicator can be found on all the RESERVOIR watches and last 35 hours. The design is inspired by vintage gauges.

  • Where does the luminosity of my RESERVOIR watch's dial and hands come from?

    The luminosity of RESERVOIR watch’s dial and hands come from Super-LumiNova treatment. Only some watch models are equipped with this treatment, as for example the HYDROSPHERE collection.

    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 the time of exposure to the source of light.

    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.
