URWERK bids farewell to its most contrarian instrument with the UR-10 SpaceMeter Blue, a 25-piece final edition that trades hourly small talk for orbital context. Less a wristwatch than a compact ephemeris, it links minutes to kilometres and places the wearer on the moving Earth rather than beside it.
The round dial is the quiet provocation. It looks almost classical at first, then promptly abandons convention. Three subdials quantify our planet’s travel through space-time: at 2 o’clock the EARTH counter tallies every 10 km of daily rotation in 500 m steps; at 4 o’clock the SUN counter logs each 1,000 km of solar orbit in 20 km increments; at 9 o’clock the ORBIT display synchronises the two, translating 1,000 km of rotation and 64,000 km of revolution across twin scales. Hours and minutes remain centrally, but they are no longer the whole story.
Turn the watch over and the narrative continues. A peripheral hand traces a 24-hour scale to echo a full terrestrial rotation. Engraved pictograms mark Rotation and Revolution, read clockwise and counter-clockwise respectively. The caseback becomes a portable cosmography – poetic in idea, rigorous in execution.
Inside ticks calibre UR-10.01, self-winding with URWERK’s Double Flow Turbine. Two stacked, counter-rotating propellers generate airflow to temper rotor speed when the winding direction is idle, easing stress on the system and adding a hint of theatre. The spec sheet is unapologetically technical: 44 jewels, Swiss lever escapement, 4 Hz and a 43-hour reserve, built from steel, brass, ARCAP, CuBe, Durnico and Nickel via LIGA, with circular and straight graining, sandblasting and polished screw heads.
The architecture is housed in a sandblasted titanium case middle with a sandblasted steel back, 45.40 mm wide, 44 mm long and 7.13 mm thick excluding the crystal. Glare-proofed glass-box sapphire crystals crown the assembly. Water resistance is 3 ATM. The ADL-treated blue dial is curved and circular satin-finished, with finely sandblasted counters at 2 and 4 and a circular satin surface at 9. In-house syringe hands carry Super-LumiNova for time; open-tipped hands serve the distance scales. A sandblasted titanium single-link bracelet closes with a titanium folding clasp.
Price is CHF 70,000 before tax. As the last of the 10 series, the SpaceMeter Blue completes an idea pushed to its limit and moves straight into URWERK’s The Legends archive – a measured ending, and a beginning of memory.
