GENERAL CARE AND MAINTENANCE GUIDELINES
Like any other piece of equipment, it is recommended that periodic maintenance be performed
on your timepiece. Observing the basic care and maintenance guidelines outlined below, in
conjunction with periodic service center cleanings, should ensure the reliability and prolonged
performance of your timepiece.
Cleaning
You should rinse your watch in fresh water occasionally to remove any sediment or other material
that may accumulate on the watch case or underneath the watch bezel during use.
This is especially important after immersion in salt water.
Crystals
Luminox watches are made with tempered mineral glass crystals, or sapphire glass crystals,
depending on the specific model. Sapphire glass crystals are highly scratch resistant; while
mineral glass crystals, though scratch resistant, are softer in composition and may exhibit surface
marring over time. A cracked, chipped, or loose crystal should be replaced immediately.
Water resistance
Luminox watches are water resistant and tested for pressures from 10 to 50 ATM, depending on the
model (as indicated on the case back of your watch), which is equal to a pressure at 100 to 500 meters
depth. The water resistance is rated based on laboratory pressure tests comparable to a swimmer or
diver sitting still at that pressure level. However many water-based activities involve a lot of movement
and other environmental changes which may challenge or defeat the water protection features of a
water resistant watch.
Water resistance cannot be permanently guaranteed. Extreme sudden changes in temperature,
accidental shock to the watch, even invisible by eye on crystal, crown or pushers, or exposure to
certain chemicals containing alcohol (suncream etc) causing the gaskets in your watch to dry out
prematurely, might compromise the water resistance of your timepiece.
With the exception of the turning bezel, the crown and/or pushers should never be operated under
water. Before wearing the watch in or under water, please ensure that all moving parts are in rest
position and that the crown has been pushed or screwed down tightly. After use in salt water, your
watch should be rinsed with clear fresh water and then cleaned and dried. Do not under any cir-
cumstances open the watch by yourself.
