Remember your watch is delicate instrument and although it does have some protection against shocks and knocks, it is not indestructible. Dropping a watch onto a hard surface or knocking can damage the workings, the case, glass, or other components. Excessive force when pulling the crown to another position or when pressing pushers can cause breakage or bending.
If a watch is rubbed against an abrasive surface such as concrete, stone, glass, or ceramic it is likely to be scratched. Sand embedded in wooden tables, or the porcelain clay in most writing paper will also scratch or abrade the case, bracelet or glass of a watch. Do not polish your plated watch with jewellery or metal polish, nor a jewellery cloth. Dust or abrasives impregnated in cloth can wear the plating.

If you notice a missing or damaged part of your watch, please bring it in immediately to avoid consequent damage, e.g. water getting into watch, or the watch coming off your wrist.

As with a car, the guarantee does not cover against accidents.


Do not expose your watch to high temperatures, e.g. placing it in the sun, on the dashboard of a vehicle, or in a hot tub. It can cause the watch to malfunction, shorten battery life or damage components. Extreme cold can cause stoppages or poor timekeeping. Thermal shock, such as putting a hot watch into cold water, can cause an otherwise water-resistant watch to leak.


No problem should occur from using the watch around ordinary household electric appliances such as TV sets or stereos. Keep away from strong magnets, transformers, radiography equipment, magnetic blankets, arc welders, magnetic toys, etc.


Do not expose the watch to chemicals, or reactive gases. Perfumes, sunscreens, insect repellants, paints, and other solvents can damage the seals or other parts of the watch. Acid, alkali, or salt solutions can damage the watch case, strap or bracelet.



Although water-resistant watches are warranted, to avoid damage that may result from accidents or mishandling: 

  • Do not operate the crown or push-button in the water or while the watch is wet.
  • Tighten screw lock crown completely, if fitted, before entering water.
  • After salt water contact be sure to rinse the watch thoroughly in fresh water to remove any salt.
  • Water resistance is not permanent; seals deteriorate with time and use. If the watch is exposed to chlorinated pools, soaps, salt water, etc the gaskets should be changed on a yearly basis.
  • If the crown or glass is damaged or missing the watch will leak. Do not expose to water but take it to your watchmaker.
  • If a watch has moisture under the glass, keep it dry and take it to a watchmaker as soon as possible. Do not store it in a closed container.

Water resistance is tested when the watch is at a static or motionless state. As the watch is moved in water, such as from the motion of swimming, pressure is added by the velocity. While you may be swimming in a pool at surface level, the watch may be experiencing forces equal to that of 30 metres of water pressure. Diving into a pool can cause forces on the watch to exceed those pressures. Water-skiing or trailing your hand in the water from a boat can cause excessive pressures or even vacuum pressure on the watch. Remember too that the water piped to your house is normally between 2.5 bar (25m) and 9 bar (90m).You should always allow a margin of safety when exposing your watch to moisture. Never "push the limit" of the degree of water resistance of your timepiece.




No marking Not water-resistant, avoid getting watch near water

20atm / 200m Professional marine activity and high speed water surface water sports.
Divers 200m & 500m Scuba diving at depths not requiring helium.
Divers with helium valve Deep sea diving at depths requiring helium gas.

1 atm (atmosphere) = 1 bar = 10m (metres) = 33 feet


Showers, Baths, Spa Pools, and Hot Pools

You should remove your watch before entering heated water. Heat from these sources can cause softening and deformation of seals leading to failure. Also, the various components used in your watch expand at different rates. This can result in the case expanding faster than the glass for example, which may allow moisture to enter.



Watches are designed to be worn on the wrist. Squashing them into tight bags or pockets when off the wrist can damage the strap or bracelet as can forcing them flat or bending them beyond their natural limits. Accidental damage is not covered by guarantee.



To extend the life and maintain the good appearance of watches, the following recommendations are given: 

  • Because the watch is worn next to the skin it collects dust and perspiration and becomes soiled if not cleaned regularly. This can cause staining of cuffs and irritation of the skin.
  • Dirt on the case or bracelet will cause increased wear on the pins and joints and can trap salt causing corrosion. It should be removed with a soft brush.
  • On water-resistant watches the bracelet can be cleaned by using a new toothbrush (not used; they have abrasive embedded in them) and warm soapy water. Thoroughly rinse with clean water at low pressure and dry completely.
  • Non-water-resistant watches should be cleaned with a soft brush or by your jeweller.
  • Do NOT use a water blaster, compressed air, or solvents to clean your watch; you WILL damage it.



Your watch will need maintenance: battery cells and water resistant seals will need replacing, after a number of years the watch will needs cleaning and re-oiling and straps will need replacing. Please take your watch to an authorised repair centre or qualified watchmaker.

If the battery in your watch is exhausted please have it replaced as soon as possible as it could deteriorate and cause other damage.
