Water resistance, although often given in metres, is not a physical depth (except when stated depth tested) that the watch is water resistant to, but rather an indication of what usage is appropriate. Below is a table showing the usage of watches for the various levels or resistance. ATM and BAR means atmospheric pressure, 1 ATM or 1 BAR is equivalent to 10 metres water pressure.
It is strongly recommended never to wear a watch in the shower, bath tub, sauna or similar places, as the extreme heat causes the metal parts to expand at a different rate than the rubber gaskets. This creates small openings that can allow water droplets to penetrate the watch, particularly steam. Do not undo the screw crown under water. Do not use the chronograph pushers underwater. Ensure your screw crown is always done up when not setting the time.
Tips for keeping your watch water resistant
|Water Resistant & Water Resistant 30m Splash resistant||i.e. rain or light water splashes, not submergible in water|
|Water Resistant 50m||5 ATM or 5 BAR||Light swimming. i.e. still water submergible such as a pool|
|Water Resistant 100m||10 ATM or 10 BAR||Surf resistance. i.e. suitable for swimming in the ocean but not at depth|
|Water Resistant 200m||20 ATM or 20 BAR||Suitable for normal diving to a depth of approximately 35m|
|Water Resistant 200m +||Suitable for diving beyond normal depths. It is recommended to check what actual depth is appropriate for the specific watch, if diving to extremes|

After swimming or diving in salt water, immediately rinse the watch in a stream of fresh water. If your watch has a rotating bezel, turn the bezel several times while rinsing it. This will prevent salt build-up and corrosion of the bezel ring. Do not undo the screw crown under water. Do not use the chronograph pushers underwater. Ensure your screw crown is always done up when not setting the time.
Just WatchesWatches should be cleaned externally periodically. For watches with less than a 50m water resistance, we recommend using a very soft brush around the face of the watch with no water, and a slightly damp cloth and very soft brush along the band. For watches with a minimum 50m water resistance, use warm water, a little soap and a very soft brush; you should work gently but purposefully to remove dust, skin particles etc. from those areas normally difficult to get at, like the back of the watch, between the bracelet links, under clasp etc. Grit and particles in bracelets can act rather like sandpaper, causing premature wear. Once the watch is clean, simply dry it off with a soft cloth and it should come up like a new watch. In store, we offer a cleaning service using an ultrasonic cleaner and specialised cleaning product.
Spray-on perfumes and hairsprays can affect a watch, therefore we recommend applications of these products prior to wearing your watch. Wearing your watch with other jewellery such as bangles and bracelets can affect the plating life expectancy.
Flat batteries must be changed promptly to minimise chances of leakage. We also recommend using a watch specialist for all battery changes, as cheap inferior batteries will not last as long and have an increased risk of leaking and corroding the mechanism, which can be unfixable without replacing the complete mechanism.
Do not place your quartz watch next to a magnet as it may stop. This is especially relative to magnetic mattresses, tourist bands, welders etc.
Leaving your watch in constant direct sunlight will reduce the life of your seals and luminosity.
If you are going to regularly wear your watch while swimming, it may be worth considering one with a metal bracelet or a rubber or nylon diver strap. Infrequent swimming will not drastically reduce the life span of a leather band that has been made for a water resistant watch of 50m or higher.
