Fit & sizing notes for the PRX 35
- What to buy: straps made for the PRX 35, or an adapter kit for this exact model. A normal-width strap won't attach on its own. Our integrated & smartwatch strap guide explains the options.
- Adapters stick out past the case, so the watch wears longer; check the adapter's output width before buying straps for it.
