Water Resistance 

 

The water-resistant quality of our timepieces is offered in varying degrees depending on the model. This 
ranges from non-water resistant models to those suitable for SCUBA diving. Water resistance of our 
timepieces is measured in BAR or Barometric Pressure. Each BAR of pressure is equal to 14.5 pounds per 
square inch of pressure. 
 
Water resistance is measured 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 from velocity. While you may be swimming in 
a pool at surface level, the watch may be experiencing forces equal to that of 100 feet of water pressure 
(3 BAR).  Diving into a pool can cause forces on the watch to exceed those pressures.  As such, 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.  
 
A primary factor to keep in mind about water resistance is that periodic maintenance is needed to 
maintain original factory specifications for water resistance. When a watch is new, it meets 
specifications for water resistance as indicated on the case back.  However, as the watch ages, the 
gaskets that seal the watch become dry and brittle, diminishing its water resistant quality. Exposure to 
environments such as chlorinated pools, salt water or soaps from showering can accelerate drying of the 
gaskets. We recommend that the gaskets be changed at least every 18 to 24 months to maintain the water 
resistant quality of your timepiece.  If the watch is frequently exposed to chlorinated pools, soaps salt 
water, etc., we recommend that the gaskets be changed on a yearly basis.  
 
From time to time, you may notice condensation that appears then goes away after a short period of time.  
This is a normal occurrence and happens primarily from sudden temperature changes. When there are sudden 
temperature changes such as entering a cool building from the hot out of doors, or jumping into pool on a 
hot day the watch may fog. Conversely, if you go to the cold outdoors from a warm building, fogging may 
occur. As long as the fogging clears in a short period of time, there is no need for concern. 
 
Be sure the crown is completely pushed in prior to any contact with moisture. If your model is equipped 
with a screw down crown, be sure it is properly seated against the case. Do not operate the crown or any 
push button when the watch is wet as this may allow the entrance of moisture. . If at anytime, you notice 
moisture in your timepiece that does not clear in a short period of time, you should send your timepiece 
as soon as possible to the nearest Authorized Service Center for inspection. 
 
You can determine the level of water resistance of our watches from the markings on your case-back. 
Additionally, models that are water resistant to 100 or 200 meters have an indication on the dial as 
well. The case-backs and dials are normally marked as follows: 
 
The case back has no indication of water resistance 
This indicates the watch is a non water-resistant model and is not designed for contact with moisture at 
all. Caution should be exercised to avoid any contact with moisture, such as when washing your hands or 
from a rainstorm.   
 
“Water Resist”  
This watch is designed to withstand water from accidental splashing, such as from washing your hands or 
rain. Any submersion into water may result in the entrance of moisture.  
 
“Water Resist 10BAR” or “W.R. 10BAR”, Dial marked “WR100” 
This watch is designed to withstand water pressure up to 333 feet. This includes water exposure from 
accidental splashing and rain, but also from showering, swimming in a pool and snorkeling. Be sure to 
rinse the watch with fresh water after exposure to a chlorinated pool, salt water, soaps, etc. After 
rinsing with fresh water, be sure to dry the exterior with a soft cloth. 
 
 “Water Resist 20BAR” or “W.R. 20BAR”, Dial marked “WR200” 
This watch is designed to withstand water pressure up to 666 feet. This includes all exposure to water up 
to and including recreational SCUBA diving. Be sure to rinse the watch with fresh water after exposure to 
a chlorinated pool, salt water, soaps, etc. After rinsing with fresh water, be sure to dry the exterior 
with a soft cloth. 
 
Special Note about Jacuzzis and Hot Tubs 
The various components used in the manufacture and assembly of your watch expand at various rates. This 
results in a loss of the sealing capabilities of gaskets, which may allow moisture to enter. In addition, 
heat from these sources can cause deformation of certain materials leading to mechanical failures. For 
these reasons, you should remove your watch before entering a hot tub or Jacuzzi.
