I recently picked up a Rios 1931 strap from WatchObsession and I’m genuinely impressed. I needed a strap that would work with fixed spring bars, and this open-ended design was the perfect solution. The clever clamp system hidden inside the ends of the strap allows it to attach securely—no sewing, no gluing, no tools. Just a smart, elegant mechanism that makes installation effortless. The strap itself is beautifully made, feels premium, and looks fantastic on the wrist. Even better, they offer smaller sizes, which is a huge plus for dress watches that often require a more refined fit. For fixed spring bars and smaller case sizes, nothing beats the convenience and quality of this strap. Highly recommended.
