This refers to a custom watch (likely a Rolex or another sports model) modified by DIW (Designa Individual – a well‑known customizer) using white NTPT carbon fiber for the case back and strap. White NTPT is rare and gives a clean, high‑tech look. The case back and strap are made from the same lightweight, textured carbon material. Perfect for those who want a stealthy yet sporty white carbon finish.
