Ulysse Nardin · Executive · Skeleton X · Ref 3716-260/03 · new on Amazon
An X of blued bridges, and nothing else in the way.
Ulysse Nardin’s Skeleton X strips the movement to a rectangle held by an X of bridges, finished in blue and set in a 42mm rose gold case with a blue bezel. The UN-371 inside is hand-wound, runs four days on a full wind, and uses a silicon escapement and balance spring; the big balance wheel sits at six where a tourbillon would be on the dearer version. Blue alligator strap. New from an independent dealer through Amazon.

The X
Ulysse Nardin launched the Skeleton X in 2019 as the affordable end of its skeleton line: the same rectangular movement frame as the Skeleton Tourbillon, but with a big oversized balance at six instead of the tourbillon cage, which cut the price by more than half. The bridges form an X across the movement, and on this version they are finished in blue against the rose gold case.
The UN-371 is hand-wound, which keeps the back of the movement as open as the front; a full wind lasts about four days. The escapement and balance spring are silicon, which Ulysse Nardin was the first house to put in a wristwatch, in the Freak of 2001.

Rose gold and blue
The Skeleton X comes in titanium, black DLC, carbon and this rose gold version with the blue bezel and blue movement finish. Gold adds weight to a 42mm case but the open dial keeps it from reading heavy. The Amazon table says automatic; the UN-371 is hand-wound, so wind it every few days and ignore that line.
Every figure here comes from the Amazon spec table where it is right and from Ulysse Nardin’s published specification for the reference, not from handling the watch.

Buying it new on Amazon
This unit is listed new by an independent dealer through Amazon, with Amazon’s 30-day return window on top of the dealer’s warranty; read the warranty line on the listing, because Ulysse Nardin’s own warranty runs from an authorised sale.
Gold Ulysse Nardins resell below their retail price on the secondary market, which is why dealer stock like this sits on Amazon under boutique retail. Buy it for the view. Nothing here is investment advice.
