Sport PVC Strap — 20mm, Square

Sport PVC Strap — 20mm, Square

A PVC sport strap fitted to a square frame, built for the modular system — durable, easy to maintain, designed for the part of life that moves.

This strap and frame exist because your watch should change with you. The modular system lets a single watch head move between formal and active — and the PVC strap-and-frame unit is what makes that transition possible without owning a second watch.

Durable PVC construction. Available in black and white. Water-friendly and easy to clean. Selected for resilience and a clean, understated aesthetic that reads as sporty without being loud. The square frame pairs with a square watch head — the strap itself is the same whether you choose a round or square frame; only the frame shape differs.

Tool-free swap. Release the watch head, click the strap-and-frame unit into place — no tools, no jeweller. A leather-strapped watch becomes an active watch in seconds. This is the combination that turns one watch into two — the one you wear to the office and the one you wear to move.

Available in 20mm — the square frame fits 36mm and 42mm Christopher Butendorff watches with a square head. Add a PVC sport strap and frame to extend your watch into the active part of your week.
