Make sure it’s always clean.
Natural oil from your skin can build up on a watch. If it’s
water-resistant, you can rub it with warm water and mild soap. If the
strap isn’t metal, clean only the case.
Maintenance
Clean and service mechanical
and automatic watches every three years. This will guarantee proper
functioning.
Damaged crystals
Restore broken or scratched
crystals instantly. Even a tiny crack can let dust and moisture into the
mechanism. It can cause a problem with the watches accuracy.

Testing glasses
Try the glasses in front of a
mirror. If you can see your eyes easily through the lenses then they
are not dark enough, which means the protection is not that great.
The right ones
Don't let labels fool you.
Look for the American Optometric Association's seal of acceptance. Buy
sunglasses where they have equipment to check UV protection.
