While “water resistance” is a common feature of most watches, there is a lot more to it than most people realize. Whether you’re a diving enthusiast, headed for a beach vacation, or just curious about water resistance, let us help you navigate what “water resistance” really means.

And please be sure to read to the end of this article, where we share important tips for caring for your water resistant watch. 

Essentially, a watch’s water resistance is determined by how well the watch case is sealed. This means that a watch’s water resistance does not remain constant and may require maintenance every couple of years to ensure accurate water resistance.
Your watch specialist can educate you about the best plan for your watch going forward. 

Note that water resistance does not refer explicitly to the depth a watch can safely go. In fact, water resistance, measured in various units including bar, atmospheres, or meters, is determined by the amount of pressure a watch can withstand, not the depth it can withstand.

WATER RESISTANCE GUIDELINES

An atmosphere or a bar are the measurements used by the watch industry to denote the amount of pressure a watch can withstand, not the depth to which the watch can be worn. ATM stands for atmosphere. 1 atmosphere is equal to about 10 meters or roughly 30 feet. 

If you are planning to regularly swim, dive, surf or boat while wearing your watch, a diving watch is an excellent option to consider.

Diving watches are specifically engineered for heavy water usage, with minimal openings for water to permeate through. They have only one screw-down crown/pusher, a sturdy case, extra heavy gaskets around the crystal, and extra heavy gaskets around the case back.

 

ISO Water Resistance Guidelines:

30m/3bars: Will resist moisture and submersion. No swimming.
50m/50bars: Will resist moisture and shallow swimming.
100m/100bars: Will resist submersion during most recreational water sports. No scuba diving.
200m/200bars: Will resist submersion during recreational scuba diving and other water sports.
1000m/1000bars: Will resist submersion during deep sea and other professional diving.

A NOTE ABOUT SHOWERING

We strongly advisable not to shower with your watch on, no matter how water resistant it is. Shampoo, soaps and other liquids are highly corrosive to a watch’s delicate components and will wear it out much sooner.

 

LEATHER STRAPS

Leather straps should never get wet. Exposure to moisture, high humidity, direct intense light, and cosmetic or oil products will cause the leather to deteriorate prematurely as well as stain or discolor the strap. If your leather strap accidentally comes in contact with any of these elements, dry the strap immediately with a soft absorbent cloth to help reduce any further damage.

Most watches with leather straps have the option of a metal bracelet as well. Our clients will often wear the leather strap during the colder months and switch over to a metal bracelet for the warm seasons.

IMPORTANT TIPS FOR PROTECTING YOUR TIMEPIECE NEAR WATER

Never turn the bezel, adjust the crown, or push the pushers while underwater as this will break the seal of the gasket, leaving the watch open for water to enter.

Always check to make sure the crown is properly pushed in or screwed down to ensure that the gasket is fully sealed.

After exposing to soap, shampoo, salt water or chlorinated water – rinse your timepiece in fresh water and dry as quickly as possible.
