The black color provides a neutral look that pairs with both casual and more formal watch faces. The strap is offered as a single-piece replacement compatible with the specified Apple Watch sizes.

How to use

Slide the strap ends into the watch’s lug slots until they click into place.

Clean the strap by hand-washing with mild soap and water and allow it to air dry before reattaching.

Usage recommendations

For prolonged accurate heart-rate or activity sensing, wear the band snugly but not overly tight so the watch sensors maintain contact with the skin. Avoid prolonged exposure to strong chemicals or bleach. Remove the strap for extended periods of immersion or heavy water activities to preserve the Velcro performance and woven material.
