C9 PULSOMETER LIMITED EDITION CHRONOMETER
C9 PULSOMETER LIMITED EDITION CHRONOMETER
English physician, Sir John Floyer (1649-1734)
first introduced the practice of pulse rate
measurement and asked clockmaker Samuel
Watson to adapt a watch for this precise
purpose some 300 years before smart phones
and watches started to monitor our every
function.
It was the early 20th Century, however, before the
Pulsometer (sometimes called a Pulsograph) watch
became widely used by the medical profession
to measure a patient's heart beat rate and the C9
Pulsometer is the latest addition in the long tradition of
these timepieces.
We have chosen not to go down the chronograph route
for our first Pulsometer, instead choosing to use a COSC
certified version of the self-winding Sellita SW200-1 as the
movement, which guarantees accuracy to within -4 to
+6 seconds a day. The beautifully engineered, 40mm
C9 case, is constructed, rather aptly, of surgical grade
Whether you are a member of the medical profession,
or just think a fine mechanical watch that can help you
monitor your health is a great idea, the C9 Pulsometer
is a special watch made even more special as only
250 pieces will ever be released. It's enough to set one's
pulse racing!
The tachymeter style pulsometer scale of the dial is
calibrated for 30 heart beats and both its red colour
and the corresponding simplicity of the remainder of
the dial make for especially easy reading. The watch
has precision blued steel hour and minute hands
but it is the hacking second hand, with its caduceus
counter-balance design, that exemplifies the usual
Christopher Ward attention to the fine details. In Greek
mythology Asclepius represents medicine and healing,
but it's Hermes staff, caduceus, which has become
widely used as the symbol of medicine worldwide, and
especially in North America.
stainless steel and the SW200 movement can be seen
working through the screw-down transparent back-plate.

THE COSC CERTIFIED CHRONOMETER
COSC CERTIFICATION
To gain chronometer status, watchmakers
submit their Swiss movements to COSC,
an independent, non-profit making watch
accuracy verification organisation based in
Geneva, to be tested against the international
standards of ISO and DIN.
Certification follows exhaustive testing. In achieving
the coveted status of Certified Chronometer, a
movement must not only be made from the highest
quality components, but also be the object of
special care on part of the finest horologists and
technicians as it is painstakingly assembled.
Only movements which meet the precision criteria
are granted an official certificate. Each uncased
movement is individually tested for fifteen days, in
five positions, at three different temperatures.
Movements are fitted with a second hand for tests
and measurements are made daily with the aid
of cameras. Based on all of these measurements,
seven eliminatory criteria are calculated, each of
which must be met.
The exacting and rigorous nature of the COSC
certification process means that the achievement
of Certified Chronometer status is extremely rare.
In fact, of all the watches produced in Switzerland
each year, just 3% bear the coveted COSC ‘bulletin
de marche’ or certificate of watch performance.
Which is why, when you read the words ’Certified
Chronometer’ on a Swiss watch you can be
sure that the movement behind the elegant dial is
a rare example of fine Swiss watchmaking which is
accurate, precise... and extremely rare.

Crown
The C9 Pulsometer Limited Edition Chronometer has a maximum power reserve of 38 hours when fully wound.
To re-power the watch after a period of non-use, simply pull out the crown and wind in approximately 20
revolutions. Normal wearing will very quickly allow the rotor to start re-powering the watch over time after
putting it on your wrist.

• From position , pull the crown to position
and adjust the calendar display in a clockwise
direction.

Please note: Date correction should not be carried
out between 20.00 hrs and 02.00 hrs as the watch
gearing will already be aligning itself to change the
date. The crown should always be screwed in after
adjustment, and it is best to do so from position 3 to
avoid advancing beyond the desired date.
