GENERAL CARE AND MAINTENANCES 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 resistant gaskets*
Your watch incorporates a series of gaskets, which work in conjunction with your care to help ensure the water
resistance of your timepiece. Over time, gaskets and crown seals will dry out, so it is recommended that all gaskets be
inspected and replaced every 18-24 months, or yearly if the watch is repeatedly used in chlorinated swimming pools or
salt water environments. Upon replacement of these gaskets, your timepiece should be tested for water resistance to
make sure that the gaskets have been installed properly. All Luminox authorized service centers will perform this test.
Water condensation
During sudden temperature variations (e.g., jumping into a cool pool on a hot day), condensation may
appear underneath the crystal of your watch. This light fogging should dissipate on its own and will not effect
the operation of the movement in your watch. If this condensation does not dissipate on its own, your watch
should be sent to an authorized Luminox service center for evaluation.
*Extreme changes in temperature (sauna, hot tub, etc.) and exposure to certain cleansers (after shave, chlorine,
etc.) may cause the gaskets in your watch to expand/contract and dry out prematurely, ultimately compromi-
sing the water resistance of your timepiece.
