USER MANUAL Khaki E.T.O Hamilton

Hamilton is delighted that you have chosen a timepiece from its collection. You have acquired a small technological marvel that will serve you faithfully for many years. The most advanced technologies were used throughout its manufacture and it underwent stringent controls before it was released for sale. Characteristics As a watch, the Hamilton Khaki E.T.O. (Estimated Time Over) quartz chronograph displays hours, minutes, sec- onds and the date. Used as a chronograph, this model can measure times up to a duration of 30 minutes. Start-Stop function Measuring a single time:

NB: Before starting to time an event, the hands should be reset to zero. If necessary, press button (B). Cumulative time function This measures successive times. Each result is added to the previous one.

Repeat these two steps as many times as desired. At the end of the last measurement, the chronograph displays the total of all the times measured. Press button (B) to reset to zero. A) Start-Stop button B) Button for resetting to zero C) Button for split-seconds function D) Crown for adjusting time and date E) Crown for adjusting the interior rotating bezel

Calculation of time (E.T.O.) Ex. Speed: 140 mph Distance to cover: 45 miles

1. Turn the exterior rotating bezel (1) so that the value

14 (a tenth of 140 mph) is facing the red arrow.

(2) = 19.4 minutes. For memorization, indicate the E.T.O. value in the window (3) by using the crown (E). Calculation of distance to cover Ex. Speed : 140 mph Time available: 15 minutes

1. Turn the exterior rotating bezel (1) so that the value

14 (a tenth of 140 mph) is facing the red arrow.

2. Read 15 on the interior xed bezel (2).

3. Read the value of the distance to be covered on the

exterior rotating bezel (1) = 35 miles. Calculation functions The bezels of the E.T.O. allow you to calculate three values: time, distance and speed, for any units of measurement. Split-seconds function (intermediate times) This function allows the display and reading of multiple successive times measured from the same starting point. The time taken to read the amounts can be caught up on without disturbing the measurement of total elapsed time.

1. Press button (A): the chronograph starts.

2. Press button (C) to read the rst intermediate time.

3. Press button (C) again. The chronograph hands catch

up with the time elapsed since the beginning of the measurement.

4. Similarly, press button (C) again to read a further inter-

mediate time, and once again to cause the hands to catch up.

5. At the end of the whole measurement, press button

(A) to read the total time.

6. Press button (B) to reset to zero.

NB: The maximum catch-up time is 30 minutes. Memorization of the last intermediate time

1. Press button (A): the chronograph starts.

2. Press button (C) to read the rst intermediate time.

3. Press button (C) again. The chronograph hands catch

up with the time elapsed since the beginning of the measurement.

4. Press button (C) to read the second intermediate time.

5. Press button (A) to read the nal total time.

6. Press button (C) to read the memorized last interme-

7. Press button (C) to return to the nal time display.

8. Press button (B) to reset to zero.

Flyback function The yback function (also known as retour-en-vol or instant restart) allows resetting of the counter hands to zero by pressing button (B) without rst stopping the timing. When the button is released, the large sweep sec- onds-hand starts a new time measurement. This function allows the user to gain some seconds in the manipulation of the chronograph, which facilitates directional calcula- tions for pilots, for instance.

restarts.6 © 24.06.2013 – HAMILTON INSTRUCTION MANUAL 7 Recommendations Like all micro-mechanical precision instruments, your Hamilton Khaki E.T.O. chronograph should be checked at least once every two years. Entrust your watch only to an authorized Hamilton agent. To keep your watch water-resistant, make sure that its sealing features are tested at every check-up. The water-resistance of your watch is 10 ATM = 100 meters = 330 feet. Your Khaki E.T.O. is equipped with a quartz movement. The electrical energy of the battery makes the quartz at the interior of the movement oscillate 32,768 times per second. This high frequency gives great accuracy. After 16 to 40 months, according to the extent to which the chronograph is used, a reduction of battery charge could result in the watch stopping. The replacement battery should be of the type Renata 394 (SR 936 SW). Five basic rules for maintaining the water-resistance of your watch

1. Have your watch checked regularly.

2. Do not move the crown when you are in water.

3. Rinse o your watch after having been in the sea.

4. Dry your watch whenever it gets wet.

5. Have your watch checked for water-resistance by an authorized Hamilton agent each time the case is opened.

Calculation of speed Ex. Distance to cover: 140 miles Time available: 8 hours

1. Turn the exterior rotating bezel (1) so that the value

14 (a tenth of 140 miles) is facing 8:00 on the interior xed bezel (2).
