Ulysse Nardin Blast Skeleton X 42mm Titanium Case

Ref. 3713-260-3/03

The Blast line is where Ulysse Nardin works without compromise — a collection built around silicon components in the escapement, anchor and gear train that require no lubrication, which matters practically because it removes the degradation that eventually costs conventional movements accuracy and service intervals. The X-shaped bridge crossing the dial is not decoration applied to a working movement but the actual architecture holding it together, which gives the skeleton its logic rather than its theatricality. At 42mm in titanium the watch sits at roughly 59 grams complete on the wrist, which is light enough that the engineering behind it reads before the weight of it does. The dial in blue shifts considerably between light conditions — the openworked bridges and floating indices produce depth in low light that a printed dial cannot approach, and the Super-LumiNova accents mean that depth continues after dark. The rubber strap, matched in blue, keeps the weight down and suits the industrial character of the case without looking like an afterthought. The 96-hour power reserve from a single barrel is genuinely useful for a manual-wind: take it off Friday evening and it is still running Monday morning. The sapphire caseback makes the silicon components visible and worth looking at — silicon runs without oil and remains dimensionally stable across temperature, which is the real point of the caseback view rather than mere display.
