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.
