Square Hour Revealed by JeanRichard Paramount Time Square

Mar 03, 2008
The Paramount Time Square from JeanRichard has been inspired by the legendary Time Square in New York. The innovative timepiece features an hour display following the lines of a square, instead of traditionally moving 'around' the circle of the dial.

The world first is equipped with the three-pointed red, blue and black rotating hour indicator advancing along the sides of a square, with each point marking the hours in turn. The creation of this amazing trajectory was based on the principle of hypocycloids, having combined a wheelwork with a set of planetary gears.

The Paramount Time Square reveals understated Bauhaus-style lines. The ample black matt dial of the watch fascinates the glance due to the full splendor of the bridges with their sunburst guilloche work, demonstrating a harmonious interplay of symmetrical effects. The newly-developed self-winding mechanical movement JR1100, a variation on the renowned JR1000, is visible through a sapphire crystal on the case-back.

The JeanRichard Paramount Time Square watch displays a perfectly balanced and elegant construction marked by avant-garde technical sophistication. The watch distinguishes due to its titanium-and-steel case, date window at 3 o'clock, and luminous hour markers.

Idea of 'Square Hour'
The 'square hour' system has incorporated a wheelwork and planetary gears. The force is drawn from the hour wheel, with the torque being transmitted to the planetary gears. The same as the hour wheel, the planetary gears daily perform two full rotations.

The 'square hour' trajectory reflects the hypocycloids principle - curves described by the trajectory of a fixed point on a small circle that rolls within a larger circle. The Paramount Time Square watch has the outer planet gear moved by the other planetary gears and meshing with the annulus.

The outer planet gear has four times fewer teeth than the annulus, so one tooth (or any other point found on the edge of the gear) traverses a hypocycloid with four cusps, also known as an astroid, a shape that much resembles the diamond formed in a deck of playing cards. In contrast, a point placed at the centre of the planet gear would traverse a circle.

The JeanRichard engineers came to the conclusion that somewhere along the radius from the centre to the edge of the circle they should find a particular point to traverse an intermediate curve between the astroid and the circle. On this very point the three-pointed hour indicator of the watch is placed, and its trajectory is very close to the shape of a square with rounded corners.
