The Opus OPUMTR44PP001, seen from the bench

The Harry Winston Opus 4 is a 44mm platinum watch representing a unique collaboration between Harry Winston and independent master watchmakers. It features a complex mechanical movement where the dial architecture and mechanical complications merge into a wearable artwork. The watch requires a custom strap solution with a special attachment for integrated bracelet compatibility.
