The 103.09

The 103.09: An updated vision of time.

The 103.09 is the latest evolution in URWERK's highly innovative 103 series of timepieces. This new model has a slightly different aesthetic treatment to the case, although the mechanics of the movement remain the same as other 103 series models.

Going forward, this new model will replace any prior orders for 103.7 models. The 103.9 is available in White Gold and Red Gold

The Urwerk 103 Series -
Four orbiting and rotating satellites display the hours, with each satellite indicating the time in a both analogue and digital fashion as it arcs across the minute chapter.

The main complexity was ensuring excellent isochronal performance of the satellites while minimizing friction and loss of energy. No simple task as, together with the supporting orbital cross, the satellite complication weighs in at 160 times heavier than traditional hands. URWERK's co-founder and master watchmaker, Felix Baumgartner, took up the challenge and chose high-tech materials to minimize mass and thus maximize chronometric efficiency. The four hour-satellites of the 103.07 are crafted in aluminium and are suspended under a grade-2 titanium orbital cross.

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 is mounted on a non-magnetic ARCAP P40 base plate providing superior strength and stability to traditional metals.

URWERK's integration of a Control Board on the back of the 103 was a world first for a wristwatch. This 'dashboard' features a 43-hour Power Reserve indicator, a chronometer with minutes and seconds facilitating accurate time-setting, and, in a nod to Abraham Louis Breguet, a Precision Adjustment screw making it possible for the owner to precisely regulate the timing of their 103.07 to match their own lifestyle.

An exceptional complication merits an exceptional case and in the 103 series URWERK's gifted designer and co-founder, Martin Frei, exceeded himself. Beginning with the geometrical base of a square and a circle, Frei designed a three-dimensional asymmetrical case the likes of which have never been seen before.

As Felix Baumgartner says, "URWERK's innovative timepiece is the result of nearly three years of development and a further two more years of testing...the end result went beyond our dreams."
