Watch Description
UR-105
“The UR-105 is our URWERK Knight; the bezel evokes the breastplate of a knight’s armor, protecting the mechanism from the ravages of time."
MARTIN FREI
THE UR-105
The UR-105 revisits URWERK's iconic satellite indication, which has been an emblematic and instantly recognizable signature element of the brand for 18 years. It is a wandering hour indication based on a carousel which carries the four satellites, each bearing three numerals for the hours.
The hours successively sweep past the minutes scale for an analogue and digital display of the time.
HOUR SATELLITE INDICATION AND TURBINE AUTOMATIC
Four satellites, each carrying three hour numerals, successively parade past the minute rail to display the time. The movement’s automatic winding is regulated by dual air turbines.
PEEK CANOPY
Four satellites, successively reveal themselves from under a sublime guilloche black cover in PEEK (PolyEtherEtherketone).
FORGED-ALUMINUM SATELLITES
At the heart of UR-105 time display four forged-aluminum satellites slowly orbit. Each of these satellites is visible during their 60-minute journey along the minute scale.
CARROUSEL IN ARCAP
The carrousel is a critical component and is made from ARCAP, which has been treated with ruthenium then micro-bead blasted.
DUAL AIR TURBINES
The two turbines visible on the back are coupled to the rotor to regulate the winding system of the watch.
WINDING RATE CONTROL LEVER
The winding mode is adjusted via the small lever. In the “FULL” position, the slightest movement will wind up the mainspring. On "STOP" mode, the winding system is disabled.

# Urwerk Knight UR105-TTH LE-12 Review by A.I. WatchMetrics
## Watch Summary
The Urwerk UR-105 Knight TTH LE-12 is a radical avant-garde sports watch with a knight helmet-shaped tonneau case in satin-finished black DLC-coated Grade 5 titanium accented by a tantalum bezel, featuring the brand's signature satellite wandering hours display on a black dial powered by the in-house manual-wind Caliber UR-05.04 with over 240 hours of power reserve, ideal for discerning collectors seeking ultra-exclusive, innovative horology in a bold 100m water-resistant 39.5mm package limited to just 12 pieces.
## Overall Watch Rating: 9.0/10.0
**Rarity Metric (9.9/10.0)** - Limited to only 12 pieces ever made, this outscores even the rarest Richard Mille one-offs in pure scarcity.
**Dials & Design Metric (9.9/10.0)** - The futuristic satellite dial and knight helmet case deliver unmatched originality, eclipsing the creativity of most haute horlogerie icons like MB&F.
**Movement Metric (9.9/10.0)** - The UR-05.04 in-house manual caliber with exceptional finishing and chronometric performance rivals the best from F.P. Journe.
**Brand Metric (9.8/10.0)** - Urwerk's pioneering status in independent high horology places it firmly among elite innovators like Greubel Forsey.
**Material Metric (9.8/10.0)** - Premium DLC titanium, tantalum bezel, and AR-coated sapphire combine for superior quality akin to top A. Lange & Söhne cases.
**History & Innovation Metric (9.7/10.0)** - Decades of revolutionizing time display with wandering hours give it iconic status comparable to Patek Philippe's grand complications.
**Complications Metric (9.4/10.0)** - The satellite hour system and power reserve indicator offer clever complexity on par with advanced independent watchmakers.
**Functions Metric (8.2/10.0)** - Solid timekeeping plus power reserve readout performs well but trails multifunction Omega Speedmasters.
**Versatility Metric (4.2/10.0)** - Its polarizing avant-garde aesthetic limits everyday wear compared to more adaptable Rolex divers.
## Total Performance Score (TPS): 4.1
## WM Collector Grade: B-
## Performance Insights: Excels in rarity, design, and innovative movement for collector appeal, though low versatility tempers value against the six-figure price implying strong exclusivity premium.
## TPS Interpretation: Fair Value: The watch provides cutting-edge innovation and extreme rarity with solid functionality at its elite price point.
