The Tissot PRX Squelette Damian Lillard Limited Edition T137.405.17.371.00 debuted in 2026, resulting from a collaboration with NBA star Damian Lillard, who has long been associated with Tissot. This timepiece marks Lillard's second special edition within the PRX series, following a previous limited release in 2024. Limited to just 1,999 units, this model introduces two significant features for the PRX line: it is the first to showcase a skeletonized design, as well as the first to incorporate a manual winding movement.

At the heart of its design is a notably larger 44 mm stainless steel case, which provides ample room for the striking openworked movement, enhancing its visual appeal compared to the traditional PRX dials. The watch is protected by a sapphire crystal on the front and features a transparent case back for an additional view of the mechanism within. With a water resistance of up to 100 meters, this watch is not just stylish but practical too. Rather than a standard dial, the front reveals the intricate architecture of the skeletonized caliber, with hour and minute hands indicating the time while omitting a date or seconds display. The openworked theme extends to the case back as well, where the manually wound movement, based on the ETA 6497-1, boasts a power reserve of approximately 52 hours and is wound via the crown. This design choice allows for an uninterrupted view of the movement, free from a rotor's obstruction. For versatility, the watch comes with two interchangeable straps, one in leather and another in rubber, and is packaged with a distinctive holder for the watch head, enabling it to be carried like a pocket watch.
