HOW TO USE
THE SLIDE RULE BEZEL
This watch is equipped with a slide
rule bezel. Two logarithmic scales are
positioned and adjustable to enable a
range of analog calculations and
measurements useful in a variety of
situations.
While you may no doubt have other
digital forms of computation available
at your finger tips, the pilot slide rule
bezel is still very much a useful, easy
to operate piece of technology to be
found on your wrist.
Turn the slide rule bezel crown to
rotate the inner slide rule bezel.
You can use it for the following
functions:
1. MULTIPLICATION
2. DIVISION
3. CALCULATING GROUND SPEED (1)
4. CALCULATING GROUND SPEED (2)
5. CALCULATING GASOLINE
CONSUMPTION
6. CALCULATING THE RATE OF
CLIMB OR DESCENT
7. CALCULATING THE DISTANCE OF
CLIMB OR DESCENT
8. NAUTICAL AND STATUTE MILE

UNIT INDEX
1: MULTIPLICATION
To divide with the Slide rule Bezel, also
use the unit index (10 with triangle).
Place the dividend (the quantity to be
divided by another number) on the outer
scale opposite the divisor (quantity by
which another is divided) on the inner
scale. Opposite the unit index (numeral
"10" on inner scale), read answer on
outer scale.
Example:
Divide 120 by 4. Place 120 on outer
scale opposite 4 on the inner scale. Read
answer, 30, on outer scale opposite unit
index (10 with triangle on inner scale).
2: DIVISION
7 8
UNIT INDEX
To multiply with the Slide Rule Bezel,
use the unit index (number "10" with
triangle in the inner scale). Always set
the multiplier (the number by which
another is multiplied) opposite the unit
index on the inner scale and read the
answer on the outer scale opposite the
multiplicand number (number to be
multiplied by another) appearing on the
inner scale.
Example:
To multiply 7 x 12, set 12 (the multiplier)
on outer scale opposite unit index ("10")
on the inner scale. Opposite 7 (the
multiplicand) on the inner scale, read the
answer 84 on the Bezel.
UNIT INDEX
The Bezel and fixed inner scales are used
for determination of ground speed
problems. Two of the following quantities
are available for its solution: time,
distance, ground speed.
Example:
Known: Distance and Time.
Required: Ground Speed.
A pilot finds by the use of checkpoint that
he has traveled 104 miles in 35 minutes.
What is the ground speed?
Solution: Move the Bezel scale until 104
on the mobile scale is set opposite 35 on
the fixed scale. Opposite the hour index
(the arrow marked "MPH" directly over the
hour 12) read 178 miles per hour on the
Bezel scale.
3: CALCULATING GROUND SPEED
(1)
109
MPH INDEX
Example:
Known: Distance and Speed.
Required: Time.
A pilot wants to know how long it will
take to go 486 miles at a ground speed
on 156 miles per hour.
Solution: On the Bezel scale set 156
opposite the MPH index on the fixed
scale. On the inner scale opposite 486
on the mobile scale read 187 minutes
(or 3 hours and 7 minutes).
4: CALCULATING GROUND SPEED
(2)
MPH INDEX
11 12
Two of the following quantities are
available for gasoline consumption
problems: Total gallons used, time,
rate of consumption.
5: CALCULATING GASOLINE
CONSUMPTION
Example:
Known: Time and Rate of Consumption.
Required: Total Gallons Used.
A pilot wishes to know how many
gallons are necessary to fly 3.5 hours at
an average rate of consumption of 11.5
gallons per hour.
Solution: Opposite the "MPH", set 11.5
on the Bezel scale. Then, opposite 210
minutes on inner scale on the Bezel scale
read 41 gallons.

MPH Index
6: CALCULATING THE RATE OF
CLIMB OR DESCENT
UNIT INDEX
Example:
Known: Rate of Ascent and Total
Elevation in Ascent.
Required: Time.
A pilot climbs to 7400 feet above his
starting point at the average rate of 500
feet per minute. How long will this
require?
Solution: Set 500 on the Bezel scale
opposite the "unit index" ("10" on the
fixed scale). Opposite 7400 on the
mobile scale, read answer, 14.8 minutes
on the fixed scale.
Two of the following quantities are
available for solution: total altitude of
descent, time and rate of descent
(or climb). 15 16
Two of the following quantities are
available: Distance, time, speed.
The methods used in examples 4 and 5
should be used.
7: CALCULATING THE DISTANCE
OF CLIMB OR DESCENT
Example:
The pilot in the previous example wishes
to know how far he will have traveled
when his climb is finished. His average
true air speed is 120 miles per hour and
he is aided by a tail wind of 20 miles per
hour.
Solution: Set 140 miles per hour
(120+20) on the bezel scale opposite
"MPH" on fixed scale. Opposite 14.8
minutes (computed from example 6) on
fixed scale read 34.5 miles on Bezel
scale.

WATER RESISTANCE
The water resistance indicated on your
timepiece serves only as a guide. Actual
water resistance may vary depending on a
number of important factors including
temperature, water salinity, and actual use
under water.
The water resistance of your timepiece
may eventually be compromised over time
with general wear and tear and the use of
your watch under adverse conditions.
Always remember to employ the screw
down crown (if available) to maintain the
water resistance of your timepiece.
Warranty may be voided if the screw down
crown has not been properly employed.
Note that you should NEVER wear your
watch in a jacuzzi, hot shower or steam
room where steam may enter the case
despite the watertight seals used to protect
your watch.
The steam may cause condensation inside
your watch, which may affect and damage
the inner workings of your watch – which
would also not be covered by the warranty.
On the fixed Inner scale both nautical
(NAUT.) and statute miles (Stat.) are
shown. The conversion from statute to
nautical or nautical to statute miles is
read directly on the Bezel.
Example:
Known: 60 Statute Miles.
Required: Nautical miles.
Solution: Set 60 on Bezel opposite to
"STAT." Read 52 nautical miles on Bezel
opposite to “NAUT.”
