A dark ink-like black case with the weight and substance of platinum, as soon as you pick this watch up, it feels special!

We are super excited to be able to offer once again an über rare limited edition of ten pieces, the UR-103 BPT Hexagon.

The Hexagon’s striking black platinum case makes a powerful statement, leaving no doubt that this is no ordinary timepiece. Created using a PE-CVD treatment (Plasma-Enhanced Chemical Vapor Deposition), creating a stunning glossy black tough coating over the dense platinum metal.

The sapphire crystal is now a sharper edge cut giving more masculine lines; this is mirrored in the time display; gone are the round hour discs now replaced with hexagon satellites giving this already three-dimensional display more depth. This starkly contrasts the soft curves of the classical 103 models.

The four-hour-satellites of the UR-103 are crafted in aluminium and are suspended under a grade-2 titanium orbital cross. The complication is mounted on a non-magnetic ARCAP P40 base plate providing superior strength and stability to traditional metals. The hour-satellites complete a full revolution under the orbital cross every four hours. As the satellite approaches the crown position, an internal Geneva cross causes it to undergo a 120-degree rotation on its own axis. This 120-degree rotation positions the next hour for its turn, indicating the time at the front of the dial. 
Over a one-year time span, each orbital cross completes 2190 rotations and each satellite 730 revolutions on its own axis!

When the lights come down, the UR-103 BTP Hexagon takes on new life, the luminescent SuperLumiNova marking the hours and minutes, indicating the time in an icy-cool blue.

Turn the UR-103 BTP Hexagon over to reveal the titanium case back, complete with our control board. Displays the power reserve indicator, 15-minute and seconds Chrono-Meter dials for precise time settings, and a user-adjustable fine-tuning screw, to micro-adjust the watch's rate if running fast or slow.

As with all our Pre-Owned collections, this UR-103.10 Black Platinum Hexagon comes fully serviced/refurbished. We also add a brand new Baltimore technical fabric strap, an original URWERK box and a new Pre-Owned international warranty for two years.

The luminescent SuperLumiNova marking the hours and minutes indicates the time in an icy-cool menthol blue. Limited edition of 10 pieces.


Felix Baumgartner - “When most people see a black watch, they think it will be lightweight, like ceramic or carbon. But we chose to use platinum, the rarest of the precious metals, for its strong properties and its heavy weight. ”

Martin Frei - "The jet-black India ink I used during my studies in fine arts was an inspiration when designing the UR-103 Hexagon. In fact, all my original sketches were always drawn in black and white since it was only with the purity of black that an idea reveals its true nature. I believe that black is the supreme colour because it attracts the light, swallows it, and contains all the other colours.”
Condition Rating UR-1: As new, no or very few signs of wear, the movement is serviced and in working condition.
