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.

HOW TO OPERATE YOUR C9 PULSOMETER LIMITED EDITION CHRONOMETER

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.

HOW TO OPERATE YOUR C9 PULSOMETER LIMITED EDITION CHRONOMETER

SETTING THE TIME

• From position , pull the crown to position

and adjust the calendar display in a clockwise

direction.

• Pull the crown to position and adjust the time

setting in either a clockwise or anti-clockwise

direction.

• After adjusting to the correct time ensure that

the crown is flush with the case in order that water

resistance is maintained.

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.
