The C90 Beckett’s Power Reserve
OWNER’S HANDBOOK

Time on your side...
Your Christopher Ward watch has been designed and engineered by highly talented craftspeople to
ensure not only accurate and precise timekeeping but also to bring a real pride of ownership that
only luxury items of the highest quality can ever hope to deliver.
You have made an investment, a good one, and the aim of this handbook is to help you make the
most of that investment during what I hope will be a lifetime of ownership.

Caring for your Christopher Ward automatic watch
Your C90 Beckett's is constructed from the finest components and materials available including one
of Switzerland’s finest automatic movements. As with all mechanical watches of this quality, with just
a little care, it has the potential to become an heirloom piece giving further joy to future generations.
Here are a few hints to help keep your watch working perfectly over the years:
• Neverfullywindyourwatchifitstops,10-15revolutionsshouldsufficetohaveitrestart.
• Tryandwearyourwatcheveryday,ifpossible,asthiswillbothenableittokeepbettertime
as well as preventing the lubricants in the movement from solidifying.
• YourwatchisfittedwiththefinestIncabloc™anti-shocksystemwhichshouldprotectitif
dropped onto a carpeted surface. However, it is best to avoid hard surfaces or sharp knocks.
You may not want to wear your watch whilst playing racquet sports, for instance.
• Therearemanydifferingviewsabouttherightfrequencyforservicingyourwatch,rangingfrom
2 to 7 years! A modern mechanical watch like yours shouldn’t need servicing more than every 3
years but we wouldn’t recommend leaving it longer than this as, just like a car, the oil needs
topping up from time to time.
• Alwaysuseareputablewatchrepairertocleanandlubricateyourwatch,andkeepany

Shouldyouneedareplacementpart-don’tworry,wekeepstocksofsparepartsforyears,evenfor
discontinued models. It’s all part of the Christopher Ward service.
Finally, don’t forget our famous 60:60 Guarantee allows you to return your watch absolutely free,
for any reason, and with no quibbles, for up to 60 days after purchase and we also guarantee your
movement for up to 60 months, so long as it is regularly serviced.
After all, why shouldn’t you enjoy peace of mind as much as you enjoy your watch?

About automatic accuracy
If you are new to automatic watches you may not be aware that generally speaking automatic
watches are not as accurate as their quartz counterparts. Whilst it is possible to fine tune an
automatic watch to within a few seconds per day, the accuracy is largely dependent upon the power
reserve in the watch at any given time. As you will appreciate the power reserve is dictated
largely by the amount of wear and the amount of movement given to each individual watch.
When you first receive your watch it is quite possible that the balance may have been upset during
its’ journey to you, and then may require a settling down period of a few days or so. After a few
weeks of wear you should be in a position to determine how your wearing habits affect the accuracy
of the watch and whether it is within the tolerances specified by ETA and CWL on page 7 of this
manual.

Setting the time/date
Position is for winding in power. Wind in a
 clockwisedirectiontore-powerthewatch.
Pull gently into position . For rapid date
correction, turn in a clockwise direction.
Pull gently into position . This position is
used for handsetting, and stopping of the second
hand. For precise time setting it is recommended
to pass beyond the desired minute and to set the
hand backwards.
Please note: Date correction should not be carried out
between 20.00 hr and 02.00 hr as the watch gearing will
already be aligning itself to change the date.
The crown should always be pushed in after adjustment, and
it is best to do so from position 3 to avoid advancing beyond
the desired date.

The Power Reserve Function
The power reserve indicator shows the winding
status of the main spring.
Position , the watch is at its maximum
winding position and has an operating autonomy
of 48 hours if it is not worn.
When the hand is in position , the movement
is close to stopping. The watch should therefore
be worn or wound up manually to obtain a
maximum power reserve.
