Sizing the Tsunami CTS (Cut-to-Size) rubber watch strap

PLAY VIDEO

To fit your wrist, the rubber watch strap can be sized by cutting it with a sharp pair of scissors or 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.

Additional Rubber Pieces

You may like to know that you can also purchase additional rubber parts.

This is useful if you need to resize your existing strap for a different wrist size or switch colours without the need to buy a whole new strap and buckle.

Another benefit is the flexibility to pair your Tsunami strap with a different HydroLock MK2 buckle finish from our available options, Full Mirror Polish, Sandblasted, Black or Antique Bronze Effect.
