Most URWERKs let the hours orbit. The UR-300 Time Quantum rebuilds them. Twelve hours sit on four three-sided prisms, carried on a T-shaped frame of two bars that keep trading roles.
Through the hour, the prism at the foot of the T travels along a 108-degree minute arc. At the sixtieth minute the whole frame jumps: the two bars pivot and swap roles, and all four prisms turn together to show the next hour.
The automatic UR-30.01V runs at 4 Hz with 44 hours of power reserve, its winding regulated by URWERK’s Dual Flow Turbines. The case is AlTiN-treated Grade 5 titanium, 45.2 by 58.8 mm, on a NATO strap. Limited to 25 pieces.
