Since 2008 Gifts of Time has successfully been servicing the greater Shellharbour community with our on time watch products (local and international brands) and servicing all your watch needs.
Our team believe that being well educated on all the watch products available in the market place is essential to making your purchase successful and an investment.
The Gifts of Time team are fully trained to be able to provide you true industry advice and help you find a watch that suits your style and lifestyle needs. It is with this philosphy that we would like to provide some education on the Water Resistance marks
So What Does Water Resistance Actually Mean and How Is It Measured?
According to the International Organisation for Standardisation (ISO), water resistance refers to a watch’s ability to resist water from entering its case. ‘A Watch’s’ water resistance is determined by how well the watch case is sealed.
A water resistant watch that is rated to a specific depth, e.g. 30m, 50m, 100m, 200m, is not necessarily designed to function at those depths. That is because the ‘meter’ used in that rating is in fact a measure of pressure, not depth.
Water resistance is actually measured in various units including bar, atmospheres, or meters, (or feet in the United States) and a watch’s rating is determined by the amount of pressure a watch can withstand, not the depth it can withstand.
Water resistance is measured in a static condition, under the pressure of a certain depth of water and velocity. Interestingly, Velocity is a function of pressure and as we have just indicated, pressure is critical to the longevity of a watch.
Even for a watch that is water resistant to 100 feet, or approximately 30 meters, it is not a security for the watches owner to assume that they can submerge their watch to the depths of 30 meters. Water can force its way pass the crystal seal, case-back gasket and the crown, or push buttons from the simple pressure and movement of the watch even in shallow water.
Sudden changes in temperature like going from a cool atmosphere into a hot temperatures can also cause the rubber gaskets, base metal and steel case parts designed to protect your watch’s water resistance, to breach its sealing capacity momentarily and allow water to leak in.
Our team have been advised and trained by our multiple watch brands/suppliers on the specifics of water resistance and we can strongly recommend not swimming or diving with your watch unless it has a screw-down crown (also known as screw-lock or screw-in crown) and is water-resistant to at least 100 meters.
