About HNBR Rubber
HNBR rubber is made to endure extreme climatic conditions, such as salt water and UV radiation, making it the perfect material to suit your diver's watch. The rubber is also incredibly strong, flexible, and comfortable to wear.
Sizing the watch strap
To fit your wrist, the rubber watch strap can be sized by cutting it with a sharp blade. On the underside of the watch strap, we have incorporated cut lines to assist in positioning the strap's cutting. Before you can cut the sections, you must first remove the buckle using a spring bar tool.
Caution: We always advise testing the fit of the watch strap on your wrist by removing 1 section at a time from the watch's opposing sides. The metal pin that is installed in each section must be removed in order to insert the spring bar.
Please be aware that the spring bars used to fit the buckle have slightly different size tips; the micro adjustment spring bar (12HR position) has a longer tip. As a result, please make sure to reattach the spring bar to the proper side of the buckle.
The micro-adjustment positions on the buckle will help you get the perfect fit to your wrist.
