Ulysse Nardin Blast Skeleton X MAGMA 42mm Carbon – BOX & PAPERS – 3713-260/MAGMA

A Red-Hot Fusion of Engineering and Expression

This Blast X Magma is an aggressively futuristic and visually explosive timepiece, engineered for those who demand the unconventional. Its stunning “magma” aesthetic is born from a daring combination of ultra-light, incredibly strong carbon fiber and vibrant red marbled epoxy resin, creating a unique angular skeletonized case that proudly showcases its mesmerizing manual-winding UN-371 movement. This watch is a bold statement of cutting-edge design, high-tech materials, and audacious haute horologerie, appealing to collectors who seek a timepiece that defies tradition and commands attention with its raw, technical artistry.

Key Features
• Case crafted from ultra-light MAGMA carbon — red resin fused with carbon fiber
• UN-371 skeletonized manual-wind movement with 96-hour power reserve
• Two OEM strap options: rubber with aftermarket deployant clasp and leather with OEM pin buckle
• Skeleton dial with red minute track and floating geartrain

Why Collectors Love It
This is not a watch for the understated collector. The MAGMA is built for presence: bold, technical, and unapologetically futuristic. It uses the same movement as the core Blast Skeleton X but with the red-hot MAGMA case that sets it apart in both look and weight. Whether you’re building a modern indie collection or want something wildly different from a typical dress piece, this stunner brings energy and an edge that few others can match.

Condition
The watch is running well and looks excellent overall. Serviced by UN on 9/2025. Little to no visible wear on the case and both straps. There is a small mark on the aftermarket deployant clasp. Additional photos or video available upon request.

Set Contents
Includes: inner and outer boxes, Ulysse Nardin blue leather folio, warranty manual, user manual, UN-branded envelope, warranty card (dated 11/2021), and warranty card holder. Comes with OEM black rubber strap (fitted with aftermarket deployant clasp) and OEM black leather strap with OEM buckle and pin clasp.
