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. The challenge with EMC was in developing
a mechanical watch that can be regulated by its owner to obtain the finest
chronometric performance. EMC is the first precision mechanical
watch that enables timing to be both easily monitored and easily adjusted
by its owner. 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. "Our
idea for EMC goes back almost six years and is a natural continuation of my
work as a watchmaker," says Felix Baumgartner, co-founder
of URWERK. "Like all watchmakers, I have
on my bench a Witschi – an instrument to test the precision of my work. This
impartial and uncompromising judge ‘listens’ to the rhythm of the balance and
makes a verdict on the performance of the movement by measuring the timing
rate, the number of seconds the movement gains or loses in 24 hours. This
device is what I always refer back to; you might say it’s my only boss in the
atelier!” EMC is inherently a precision mechanical watch with an
in-house movement conceived, developed and crafted in the URWERK ateliers in
Zurich and calibrated by URWERK in Geneva. The movement meets the most
stringent quality control, with its chronometric performance tested in five
positions during a 30-day cycle to ensure that it meets the highest standards
for a precision watch. The innovative EMC timing rate monitoring unit has been developed to include the following: - An optical sensor on the
balance wheel capturing the precise rate of oscillation of the 4 hertz / 28,800
vph regulator, over a period of 3 seconds. This sensor consists of a transmitter
and a receiver positioned either side of the balance, and is triggered manually
by pressing a button on the left side of the case. - A 16,000,000-hertz electronic oscillator This provides EMC’s reference timing rate. The performance of the balance of EMC (4hz) is compared against this lightning-fast oscillator to obtain the most accurate measurement possible. - Artificial intelligence (the computer) This computer determines the difference between the timing rate of the movement and that of the reference oscillator. Each microsecond difference between the two values is expressed as a gain or loss of a second per day of the timing rate. A variation of just 0.0000014 of a second per half-vibration translates as a variation of a second per day. - Manual-winding generator (the generator): EMC’s monitoring unit (the optical sensor and the computer) is powered by a micro-generator made by the Swiss company Maxon, which is well known for developing motors for NASA’s Mars rovers. Martin Frei – designer and co-founder of URWERK - had
the considerable task of bringing all of EMC’s technical elements together in a
visually-appealing and comfortably-wearing wristwatch. "At URWERK, the starting point of our creations is usually a
sketch of the completed watch that embodies mine and Felix’s ideas before the
micro-mechanics are fully developed. But with EMC, the technical features of
the timepiece were already established and this made my task that little bit
trickier. We miniaturised the EMC components to the extreme and this allowed me
some leeway in terms of design. My approach was one of pragmatism – from
incorporating the folding crank into the caseband, to making the electrical
energy storing capacitor part of the case. In terms of design, you can spot the
influence of objects that are dear to me: the crank echoes that of old SLR
cameras; and the design of the balance wheel is reminiscent of a vintage 1/4
inch tape reel. EMC
marks the dawn of a new era, that of an interactive smart mechanical watch allowing
the owner to gauge the precision of their timepiece’s chronometric performance
and fine-tune it to better suit their daily rhythm and pace of life.
