Corrosion usually will be
your biggest worry, most often caused by an acidic material, usually
salt water or human sweat. All gold is susceptible to
corrosion and does not indicate that the replica or genuine watch is
of poor quality. The best guard against
corrosion is to wash the gold parts with soap. Dry the watch off
completely and take it off during heavy perspiration. Don't expose it to long
periods of water submersion, if any. You can apply a coating of
clear nail polish over the gold to prevent the gold from fading.
