Catalyst Universal Watch Bands

Watch bands sized by lug width, not by watch model. These bands fit by measurement, so they work with Catalyst Apple Watch cases and with any watch that takes a standard spring bar at the same width. Measure the gap between the lugs and match it. How to choose 22mm — Fits the smaller Catalyst watch cases and any 22mm lug. 24mm — Fits the larger Catalyst watch cases and any 24mm lug. Loop and Buckle — Loop pulls through and folds back; buckle fastens like a traditional strap. If you are replacing a band on a Catalyst case, match the lug width shown on your case's product page.
