AVI-8 Hawker Hurricane Classic Chronograph AV-4011

Chronograph Watch

This watch is powered by a quartz Chronograph movement capable of split micro measurements of time. With pinpoint accuracy, you can use this watch to measure separate periods of elapsed time while simultaneously reading the current time.

Key Components:

• Hour Hand
• Minute Hand
• Second Hand
• Stopwatch 1/10 Second Hand
• Stopwatch Second Hand
• Stopwatch Minute Hand
• Date Window
• Tachymeter Bezel
• Push Button A
• Push Button B
• Crown

Crown Positions:

• Position 0: Closed for water resistance.
• Position 1 (1st Click): Opened, not secured for water resistance. Used for setting time and date.
• Position 2 (2nd Click): Opened, not secured for water resistance. Used for setting time and date.

How to Set the Date and Time

Before setting the time, ensure the chronograph measurement is stopped.

1. Pull the crown out to position [1] (1st click).
2. Turn the crown clockwise until the previous day's date appears.
3. Pull the crown out to position [2] (2nd click). When the second hand is at the 12 o'clock position, it will stop. Set the hands to the desired time of day (ensure A.M./P.M. is set correctly) by turning the crown.
4. Push the crown back to position [0] in accordance with a time signal.

Important Notes:

• When the crown is at position [2] (2nd click), do not press any pusher, otherwise the chronograph hands will move.
• Do not set the date between 9:00 P.M. and 1:00 A.M., otherwise the date may not change properly. If it is necessary to set the date during this period, first change the time to any time outside this range, set the date, and then reset the correct time.

Stopwatch Function

• The measurement of time is indicated by the stopwatch hands that move independently of the center hands.
• The stopwatch can measure up to 60 minutes.
• The stopwatch measures in 1/10 second increments.

Standard Measurement

• Start: Press Button A.
• Stop: Press Button A.
• Reset: Press Button B.

Accumulated Elapsed Time Measurement

• Start: Press Button A.
• Stop: Press Button A.
• Restart: Press Button A.
• Reset: Press Button B.

Restart and stop of the stopwatch can be repeated by pressing Button A.

Split Time Measurement

• Start: Press Button A.
• Split: Press Button B to record a split time. The stopwatch continues to run.
• Release: Press Button B again to resume timing from the split time.
• Reset: Press Button B.
• Stop: Press Button A.

Measurement and release of split time can be repeated as many times as necessary by pressing Button B.

Adjusting Stopwatch Hands Position

Before setting the time, check if all chronograph hands (1/10 second, second, minute) are at the “0” (12 o'clock) position.

If the stopwatch is in use, press the buttons in the following order to reset it and check if the hands return to the “0” position:

• If the chronograph is counting: Press A then B.
• If the stopwatch is stopped: Press B.
• If the split time is displayed: Press B, then A, then B.

If any of the stopwatch hands are not in the “0” position, reset them by following the procedure:

1. Pull the crown out to position [2] (2nd click).
2. Press Button A or B to reset all stopwatch hands to the “0” position.
3. The stopwatch minute hand moves correspondingly with the stopwatch second hand.
4. The hands move quickly if the respective buttons are kept pressed.
5. Push the crown back to the normal position.

Visual Aid: The diagram shows the stopwatch hands at their zero positions after resetting.

Using the Tachymeter

The most common use of a tachymeter is for measuring the approximate speed of a vehicle over a known distance.

Example: Based on how many seconds it takes a vehicle to travel 1 km or 1 mile (the available measuring range is up to 60 seconds), the average speed within the distance can be calculated.

1. Start the chronograph when the vehicle commences travel.
2. After the vehicle has travelled 1 km or 1 mile, stop the chronograph.

The approximate average speed within the distance can be determined by observing the present position of the stopwatch second hand and reading the outer bezel.

Example Calculation:

If the stopwatch second hand points to 9 o'clock (45 seconds elapsed), the tachymeter scale should be read at 9 o'clock. The average speed is 80 KPH (50 MPH).

Note: Tachymeter indications may appear on the dial ring rather than on the outer bezel, depending on the model.

How to Use a Deployant Clasp

1. Flip the cover.
2. Press the buttons on the clasp sides.

How to Resize Metal Bracelet

On the inside of the bracelet, you will see small arrows engraved on removable links.

1. Identify the links with engraved arrows indicating the direction of pin removal.
2. Use a bracelet tool or a small pin pusher to push the pin out in the direction of the arrow. A nylon head hammer may be used gently if needed.
3. Remove the pin and the link.
4. To reattach or adjust, insert the pin into the desired link hole and push it through.
5. For micro size adjustment, use the adjustment holes on the clasp. Insert a pin tool and push the pin out of its current hole, then reposition it into the desired micro-adjustment hole.

Visual Aid: Diagrams illustrate the process of removing and inserting pins to adjust bracelet size, including micro-adjustment on the clasp.

Water Resistance

The water resistance chart serves as a guide. Actual water resistance may vary depending on factors like water temperature, salinity, and usage.

Important Note: Never wear your watch in a jacuzzi, hot shower, or steam room, as steam can enter the case and cause condensation, potentially damaging the inner workings of your watch.
