My Quiksilver Lanai was a gift from my girlfriend a few years ago. I immediately replaced the rubber strap with a custom leather one. This way I never found out that the rubber strap did not have a long life myself. After posting a few replacement strap I did get more orders and apparently after a few moths the standard strap breaks and people start looking for a replacement strap for their Quiksilver Lanai watch. Below you see one for a black and green version of the Lanai. The customer will add the one hole needed for his wrist himself to give that true custom feel.
Imagine, Create & Enjoy
