The Bearing of a Shaft that Measures Only
Six One-Thousandths of a Centimeter, the Diameter
of a Normal Human Hair

WE
VE told you in our last adver-
tisement that the twelfth part
of a human hair was the difference
between the Waltham standardized
accuracy and the variable guess-
work in foreign watches.

A normal human hair measures six
one-thousandths of a centimeter.
Imagine, then, the pivots or bear-
ings of the Balance Shaft being only
the size of a human hair.

If you should split one of the hairs
of your
head into six equal parts,
each part would measure approxi-
mately one-thousandth of a centi-
meter. Yet, even this minute varia-
tion is eliminated by the Waltham
standard of measurement.

For instance, here is a Waltham

Watch, the works of which are de-
signed to perform on a pivot mea-
surement of six one-thousandths of
a centimeter.

But suppose this pivot was enlarged
the third part of a human hair, fric-
tion would be increased, causing a
variation in the time-keeping qual-
ities of the watch.

The Waltham Watch Company has
created marvelous gauges that meas-
ure even the twelfth part of a human
hair to determine these variations
and eliminate errors unseen by the
human eye in the works of a watch,
which mean all the difference to you
in dependability and value, giving
another of those unanswerable rea-
sons why your watch selection
should be a Waltham.

This story is continued in a beautiful booklet in which you will find
a liberal watch education. Šent free upon request to the

The Watch of Railroad Accuracy"

When you miss a train or an important appointment, you know how your schedule for one whole day simply goes all to smash.

Keep to your schedules by a watch whose accuracy is proved by the thousands of railroad men who prefer it. Hamilton Watches are the timekeepers most popular with American railroad men.

For example: Conductor Dan Mandaville, shown above, has been in Erie

service 45 years. His run
is between Jersey City and
Binghamton-out on No. 5,
back on No. 6. He has been
carrying for 14 years that
Hamilton he holds in his
hand.

A Hamilton used as a gift,
prize, or reward is received
with greater delight because
of its high reputation.

There's every desirable kind. Prices range from $40 to $200. Movements alone, $22 (in Canada $25) and up.

Send for "The Timekeeper"-an interesting booklet about the manufacture and care of fine watches. The different Hamiltons are illustrated, and prices given.
