What is the O-ring?
The O-ring is a waterproofing packing used for underwater cameras, watches and 
diving equipment.
The O-ring keeps the Case waterproof by sealing the gap between the rear case 
and the front case.
∫ How the O-ring keeps the Case waterproof
The gum comes into contact with the sides of the Case making the Case 
waterproof and stopping water from entering from the gap.
When water pressure acts on the O-ring, the surface of the O-ring expands 
and the Case is sealed more tightly.
The O-ring prevents water leakage by coming into uniform contact with 
the sides of the Case. Therefore, good care of the O-ring is very 
important. Incorrect care of the O-ring may cause water leakage.
