Frequently Asked Questions - Khaki X-Wind Hamilton

How to set the time on the Hamilton Khaki X-Wind?

Unscrew the crown A (position 0), pull it to position III, turn to set the time, push back and screw down.

How to set the date and day?

Unscrew the crown A, pull to position II. Turn counterclockwise for the date, clockwise for the day. Avoid between 8 PM and 2 AM.

How to use the chronograph?

Press B to start/stop, press C to reset. Simple or cumulative timing.

How to calculate crosswind with the Khaki X-Wind?

Position the red arrow (upper bezel) at 12 o'clock, set the inner bezel to 0°. Indicate the wind direction on the upper bezel (crown D), the aircraft speed on the outer bezel opposite the red arrow. Use the nomogram to find the crosswind, then read the drift angle on the inner bezel.

How to manually wind the watch?

In position I (crown unscrewed but not pulled), turn the crown 30 times clockwise. The power reserve is 60 hours.

What is the water resistance of the watch?

It is indicated on the case back. Generally 10 bar (100 m). After each immersion in seawater, rinse with fresh water.

How to maintain the leather strap?

Avoid water, humidity, sun exposure, and fatty substances. Leather is permeable and discolors on contact with water.

What to do if the watch is exposed to a magnetic field?

Keep it away from magnets, speakers, phones, refrigerators. If malfunctions persist, consult a professional.

When and where to have the watch serviced?

Every 2 years, entrust it to a Hamilton dealer or authorized watchmaker to check water resistance and movement.

How to clean the watch?

Use a soft, dry cloth. After contact with seawater, rinse with fresh water and dry. Do not immerse the leather strap.

Recommendations

• Like all micro-mechanical precision instruments, your Hamilton watch should be checked at least once every two years. Entrust your watch to an authorized Hamilton repair center or to any other professional watch service.
• To keep your watch water-resistant, make sure that its sealing features are tested at every check-up.
• Do not move the crown when you are in water.
• Rinse off your watch with fresh water after any immersion in seawater.
  • Dry your watch whenever it gets wet.
• Have your watch checked for water-resistance by an authorized Hamilton retailer or by any other professional watch service each time the case is opened.

Water-resistance

The water-resistance of your watch is indicated on the case back.

Water resistance and equivalent pressure used in Anglo-Saxon countries:

Unit of measure Water resistance categories available
atm (overpressure) 351020100
psi	44	72,5	145	290	1450
ft *	100	165	330	660	3300

Water resistance and equivalent pressure used in countries using metric systems:

Unit of measure Water resistance categories available
bar	3 5 10 20	100
m*	30	50	100	200	1000

* The values given in feet or meters of immersion in water are equivalent to the degree of overpressure applied during the tests according to the ISO 22810 standard.

Leather straps

Hamilton recommends that you follow the steps below in order to preserve the condition of your leather strap for as long as possible:

• Avoid contact with water and dampness to prevent discoloration and deformation.
• Avoid prolonged exposure to sunlight to prevent the color from fading.
• Do not forget that leather is permeable! Therefore avoid contact with greasy substances and cosmetic products.
• If you have a problem with your leather strap, please contact your nearest Hamilton retailer.

Magnetic fields

To prevent malfunctions of your watch avoid coming into contact with magnetic fields such as those of magnets, loudspeakers, cell phones, refrigerators, etc.

Operating instructions

Movement

Your watch is fitted with an automatic movement. The mechanism of the watch includes an oscillating rotor that winds the mainspring via the motion of your wrist. The power reserve is up to 60 hours.

If necessary, the movement may be rewound manually by turning the crown clockwise 30 times in position (I). With most of our models, the beauty of the inner working of the watch movement can be admired through the transparent case back.

The Hamilton Khaki Automatic X-Wind has three screw-down crowns and two push-buttons.

Important: to keep your watch water-resistant, always screw the crowns A, D, and E back to position (0) after all the settings.

Setting the time

1. Unscrew setting crown A.
2. Pull out the crown completely to position (III).
3. Adjust the time by turning the crown in the desired direction.
4. Push back the crown completely then screw it down again.

Setting the date / day

1. Unscrew setting crown A.
2. Pull out the crown to the intermediate position (II).
3. Turn the crown anticlockwise until the desired date appears, or clockwise for the desired day. Do not perform this operation between 20:00 and 02:00 (8 p.m. and 2 a.m.).
4. Push back the crown completely then screw it down again.

Chronograph functions

Simple or added timing

1. Press button Ⓑ to start the chronograph.
2. Press button Ⓑ again to stop the chronograph. The elapsed time or the first partial time is indicated by the hands of the counters ④, ⑤ and ⑥.
3. Repeat these two steps for each additional timing. At the end of the last timing, the chronograph will indicate the cumulative time of all the partial timings added together.
4. Push button Ⓐ to reset the counters to zero.

Operating instructions

Crosswind

The Khaki X-Wind integrates a drift – angle calculator, enabling pilots to accurately calculate and record the crosswinds they will encounter on their planned journey.

1. Position the red arrow of the upper interior rotating bezel ⑨ at 12 o'clock by adjusting with crown D.

Adjust the lower interior rotating bezel ⑩ to 0^irc by adjusting with crown E.

1. Obtain wind speed and direction from control tower or weather chart.

Ex. Wind speed: 40 mph

Wind direction: 70^irc

Indicate wind direction (70) in the window with the upper interior rotating bezel ⑨ by adjusting with crown D.

1. Adjust the exterior rotating bezel ⑧ so that one tenth of the speed of the aircraft is indicated opposite the red arrow.

Ex. Aircraft speed:

180 mph – indicate 18.

1. From the geographical bearing, calculate the magnetic bearing of the aircraft:

The variation (Var) depends on the current location, which can be determined from an aviation chart.

Ex. Geographical bearing: 30°

Variation (Var): 10°

Magnetic bearing: 30^irc + 10^irc = 40^irc

Tn: True North | Mn: Magnetic North | Var: Variation

If the variation (Var) is to the West, it is added to the geographical bearing to obtain the magnetic bearing.

Ex. 30^irc + 10^irc = 40^irc

If the variation (Var) is to the East, it is subtracted from the geographical bearing to obtain the magnetic bearing. Ex. 30^irc-15^irc=15^irc

1. Calculation of crosswind angle.

Ex. Wind direction: 70°

Magnetic bearing of aircraft: 40°

Crosswind angle: 70^irc-40^irc=30^irc (headwind)

70^irc - 40^irc = 30^irc (Headwind)

180^irc - (330^irc - 220^irc) = 70^irc (Tailwind)

360^irc - (330^irc - 40^irc) = 70^irc (Headwind)

Operating instructions

6. Calculation of crosswind:

Using the graph (plastic card) determine the point of intersection of the wind speed (head/tailwind component) and the crosswind angle.

Going from the point of intersection, read the value of the crosswind component on the horizontal axis.

Ex. Headwind component: 40 mph

Crosswind angle: 30°

Crosswind component: 20 mph

7. Calculate the angle of drift:

Locate the crosswind component (20) on the exterior rotating bezel ⑧ and read the value indicated on the interior bezel ⑨.

Ex. Angle of drift: approx. 6.5°

8. Calculation of corrected bearing:

If the wind is blowing from the right, add the angle of drift to the magnetic bearing.

If the wind is blowing from the left, subtract the angle of drift from the magnetic bearing.

Ex. Corrected bearing: 40^irc + 6.5^irc = 46.5^irc

For memorization, use the crown Ⓔ to indicate the corrected bearing (t) on the lower interior rotating bezel ⑩.
