  • 2 o’clock eye shows “1/20 seconds elapsed” for chronograph.
  • Chronograph second hand shows “seconds elapsed” for chronograph.

Time and Calendar

Time

To Set the Time

  1. Pull crown out to “C” position.
  2. Turn crown either way to correct time.
  3. Push crown in to “A” position.

To Adjust to a New Time Zone

  1. Pull crown out to “B” position.
  2. Turn crown either way to move the hour hand in hour increments.

Calendar

To Set the Calendar

  1. Pull crown out to “B” position.
  2. Turn crown either way to move hour hand. Two complete revolutions relative to the 12 o’clock position will move the date forward or backward. This will correct both date and 24-hour time.
  3. Push crown in to “A” position.

Chronograph

The chronograph is capable of measuring:

To Adjust Chronograph Hands

  1. Pull crown out to “B” position.
  2. Press pusher “B” until the hand at the 10 o’clock eye resets to the “30” position.
  3. Pull crown out to “C” position.
  4. Press pusher “A” until the chronograph second hand resets to the “0” or “60” or 12-hour position.
  5. Press pusher “B” until the hand at the 2 o’clock eye resets to the “0” position.
  6. Push in crown to “A” position.

Slide-Rule Bezel Function

Watch bezel diagram labeled Outer Ring and Inner Ring

The slide rule function of the top ring operates by rotating the outer ring. The inner ring does not move. The outer ring is always related to “distance” or “speed”, or any data that varies with time. The inner ring only notes units of time.

Outer Ring

On the outer ring, the figure “10” represents factors or multiples of 10, such as 0.1, 1.0, 10, or 100.

Inner Ring

On the inner ring, “MPH” (mile per hour) refers to “speed index”. This index is used to calculate the speed involving any data per hour. On the inner ring, “STAT” (statute miles) and “NAUT” (nautical miles) are for conversion of distance units.

The following examples serve as a guide of how to use the slide rule.

Speed Calculation

What speed is required to go 10 nautical miles in 15 minutes?

Known Factors: Distance: 10 nautical miles. Time: 15 minutes.

  1. Align “10” arrow on the outer ring with “15” on the inner ring.
  2. The speed required can be found directly above the “MPH” marking on the inner ring.

The answer: 40 nautical miles per hour.

Time Calculation

How long will it take to go 10 nautical miles at a speed of 40 miles per hour?

Known Factors: Speed: 40 miles per hour. Distance: 10 nautical miles.

  1. Align “40” on the outer ring with the mark “MPH” on the inner ring.
  2. The time required can be found directly below the “10” arrow on the outer ring, which is “15” on the inner ring.

The answer: 15 minutes.

Distance Calculation

How far can you travel at 40 miles per hour for 15 minutes?

Known Factors: Speed: 40 nautical miles per hour. Time: 15 minutes.

  1. Align “40” on the outer ring directly above the mark “MPH” on the inner ring.
  2. The distance travelled can be obtained above the “15” marker on the inner ring. The number indicated on the outer ring is “10”.

The answer: the distance travelled is 10 nautical miles.

Unit Conversion

To convert distance from nautical miles to statute miles and kilometers.

Known Factor: Distance to convert is 10 nautical miles.

  1. Align the “10” arrow on the outer ring above the “NAUT” on the inner ring. The conversion in statute miles (11.5) is found above the inner ring “STAT” marking, and the conversion to kilometers (18.5) is found above the inner ring “MPH” marking.
