Urwerk’s latest version of the UR-110 Torpedo is the UR-110 ST. It has a steel front plate engraved with horizontal grooves and coated in black AlTiN, coupled with striking yellow numerals and indices.
The time is shown on the right side of the watch. Three hour satellites follow a vertically arced line, graded from 0 to 60 minutes, in a downward motion.
Planetary gearing keeps the satellites and their arrow-shaped “torpedoes” in parallel formation as they take turns to indicate the time as they pass the 60-minute track.
