Query: Great through warranty period but.....

On the plus side, it is the most comfortable watch I've ever owned due to the nylon and velcro strap. The luminous lines showed brightly at night and were easy to read.Got this as a gift for Christmas. 4 months after warranty expired, moisture showed up inside the case. Emails to campco just went around and around. All I did was wash my hands. I had never changed the battery because it didn't need it and the screw on the side was screwed down as tightly as possible. Poor customer service by Campco. Avoid this watch and spend the extra money for a better manufacturer with better customer service that stands by their product like Traser or possibly Luminox. You get what you pay for.
