Dan Henry 1963 40mm Pilot Chronograph instructions

Your Dan Henry 1963 Pilot Chronograph is a 60-minute chronograph with a 12-hour GMT rotating bezel.

Meca-quartz timekeeping

Your Dan Henry 1963 pilot chronograph is equipped with the Seiko VK63 meca-quartz 60-minute chronograph with tachymeter scale and 24 hours indicator sub-dial.

What is “meca-quartz chronograph? Meca-quartz is a hybrid design: in a meca-quartz chronograph, the timekeeping functions are controlled by a battery-powered quartz movement, while the stopwatch functions of the chronograph are recorded by a mechanical module that is also powered by the battery.

Meca-quartz movements have been used for four decades in the most rugged and reliable chronographs. The Seiko movement in your

Dan Henry 1963 pilot chronograph is a direct descendant of the first meca-quartz movements used in premier chronographs.

Functions

1. Setting the time:

1.1. Pull out the crown to the second click position.*

1.2. Turn the crown to set the hour and minute hand.

1.3. Check that AM / PM is set correctly by looking at the 24-hour sub-dial in the 3 o’clock position.

1.4. Push in the crown to the normal position.

* If the crown is pulled to the second position while the chronograph is started, the chronograph hands will continue to move. This is not a malfunction.

2. Setting the date (for models with date windows):

2.1. Pull out the crown to the first click position.

2.2. Turn the crown clockwise to set the date.

* Do not change the date when the hands are set between 9 PM and 3 AM, because the day may not change properly. If it is necessary to set the date during that time, first change the hands to any time outside of that range; then set the date and then reset the correct time. (Use the 24 hours sub-dial located at 3 o’clock to help you when setting the date)

2.3. Push in the crown to the normal position.

3. Using the chronograph:

Your Dan Henry 1963 pilot chronograph features a stopwatch that can measure up to 60 minutes.

3.1. To start the chronograph: press the upper pusher. The chronograph hands will begin to move.

3.2. To stop the chronograph: press the upper pusher again. The chronograph hands will stop and indicate the elapsed time. (Read the elapsed seconds on the large central hand and minutes on the sub-dial in the 9 o'clock position.

3.3. To reset the chronograph: press button the lower pusher to reset the chronograph. All the chronograph hands will be reset to "0” position.

4. Using the 12-hour GMT Bezel

The Dan Henry 1963 pilot chronograph is equipped with a rotating 12-hour GMT bezel, so you can track a second-time-zone. For example, to monitor the time in a city that is 5 hours ahead of you, just turn the bezel counter-clockwise for 5 clicks or 5 hours, and read the hours of the second timezone in the bezel.

5. Water resistance

Your chronograph has been tested for water resistance. It is safe to wear in a swimming pool, but not for scuba or ocean diving. The crown must be pushed in completely to ensure that the watch is water-resistant.

6. Accuracy and battery replacement

The accuracy of the movement is 20 seconds a month. With normal use, the battery in your Pilot Chronograph should last about three years.
When the watch begins to run slow, it indicates that the battery should be changed. Use a ref. SR927W or 395 battery. The life of the battery can be shortened by extreme heat or cold.
The battery life can be conserved while not using the watch by pulling out the stem to stop the watch.
