For
URWERK, a precision timepiece should have at its base a movement that is
accurate, reliable and long lasting. Such a movement should meet
specific criteria including accuracy in 5 positions between -4 seconds
and +6 seconds over 24 hours. However, while it is one thing to
regulate an accurate watch in the controlled world of a workshop, performance
in the sometimes-extreme real world, i.e. on the wrist, can be very different.
Changes in position and temperature, and shocks, can all adversely
affect isochronism (timing regularity) of a wristwatch.

With EMC, not only can the wearer obtain the precise
timing rate on demand, they can then use that information to accurately adjust
the timing of their watch to suit their own personal rhythm. Electro Mechanical Control (EMC) is the
world's first precision mechanical watch in which the timing can be monitored
and adjusted by the user to suit their lifestyle – EMC is fully interactive.
Please note that EMC is a fully 100% mechanical watch. The electronics have absolutely no effect on the movement; they only enable monitoring of the movement's precision in a similar way that the electronic speedometer or rev counter of a car has no effect on the mechanical engine and gearbox.

EMC features a deconstructed dial with four separate
indications: A clockwise tour of the displays, from top left, presents the: on
demand, precision indicator (instantaneous rate delta δ) ranging from -20 to + 20 seconds per
day; seconds dial with counter-balanced seconds hand; hours and minutes; and
80-hour power reserve indicator. Turning EMC over reveals the fully in-house
movement with the integrated circuit board – the EMC 'brain' –, the top of one
of the two mainspring barrels near the crown and the top of the balance wheel
and optical sensor on the winding handle side.

The audacious idea to incorporate a Witschi-like measuring instrument in a mechanical watch became a veritable quest for URWERK. “EMC allows you to obtain a reliable and accurate piece of data on your timepiece at the touch of a button – information that until now has been the preserve of professional watchmakers,” says Baumgartner. “Using this information, you can fine-tune one of the most exciting, most jubilant mechanisms invented – the mechanical watch – all by yourself.”
At its heart, EMC has a triple objective: to show how external parameters (positional changes, temperature and pressure) influence the timing of the movement; to enable the wearer to adjust the timing; and to facilitate interactivity between the timepiece and its owner.
