Product Information
The Calibre 28D & M2761 is an automatic watch manufactured by Ingersoll. It features a screw-down crown and buttons for added water resistance. The watch has a power reserve of up to 30 hours when taken off the wrist. It is important not to overwind the watch as it may cause damage to the movement. The watch is water-resistant up to a certain depth, depending on the model.
Product Usage Instructions
AUTOMATIC WATCHES
An automatic or self-winding watch is a mechanical watch in which the
mainspring is wound automatically as a result of the natural motion of the
wearer’s arm, making regular manual winding unnecessary. The winding of the
automatic mechanism depends on the intensity of your movements. When you
receive the watch for the first time it may not be running. This is because the
watch has no power to operate. The watch must be given an initial manual wind
with 15 to 20 turns of the crown and then while the watch is worn it will wind
itself and maintain the correct time. When setting the time please ensure the
hands only move in a clockwise direction to avoid damage. The accuracy
tolerance of our automatic movements is -40 to +40 seconds per day, worn under
normal conditions.
Automatic Watch Power Reserve
To maintain power, the watch can be taken off the wrist for a maximum
period of 30 hours. If this period is exceeded, the movement will stop and
manual winding will be necessary. It is important to note that wearing the
watch while sleeping may not provide sufficient movement to maintain automatic
winding. In order to maintain power the watch may be taken off the wrist for a
maximum period of 30 hours. If this period is exceeded the movement will stop
and another manual wind will be necessary. It must be remembered that if the
watch is worn while sleeping the movement of the wrist is insufficient to
maintain the automatic winding function.
Caution: Do not overwind your watch as this may cause damage to the
movement.
Screw-down Crowns & Buttons **
**
Some Ingersoll watches have screw-down crowns or buttons for enhanced water resistance. To make a screw-down crown operational, unscrew it from the case by turning it anti-clockwise until it releases. To reseal the crown, press it in against the case until the threads engage and turn clockwise until tight. To make a screw-down button operational, unscrew it from the case by turning it anti-clockwise until it stops. This allows the button press function to be activated. To reseal the button, turn clockwise until tightly screwed against the case. To safeguard your investment, it is important to understand how these types of crowns and buttons work.

Water Resistance **
**
The watch has different levels of water resistance, indicated by ATM (atmospheres). It is recommended to consult an Ingersoll approved specialist to determine the specific water resistance level of your watch. The watch can withstand splashing, swimming, snorkeling, and diving up to a certain depth, depending on the model. All Ingersoll models have a water resistant construction and are individually tested. Check the water resistance level of the watch before submerging into water. To maintain water resistance the crown and buttons must be fully pushed into the case and not operated when in contact with water. Water resistance is not permanent. In the course of time, the gaskets of the case and crown may become worn and may reduce the water resistance of your watch. Slight shocks applied to the crown or rapid temperature changes can damage the seals and impair the water resistance. We recommend periodic checking. Fogging of glass may not necessarily indicate the entry of moisture, it can also be caused by extreme temperature changes. If this occurs, it is highly recommended to check with an Ingersoll approved specialist.

Watch Care **
**
To ensure the longevity of the watch, it is recommended to have it serviced by an Ingersoll approved specialist. Avoid exposing the watch to extreme shock or impact, as it may damage the movement.
- Clean your watch with a soft cloth and water only.
- Do not submerge your watch under water unless it has the required level of water resistance.
- After saltwater use, rinse watch under tap and wipe dry with a soft cloth.
- Metal bracelets should be cleaned periodically. Clean with a soft brush dipped in mild soapy water and dry thoroughly with a soft cloth.
- We advise having your timepiece serviced every 18 – 24 months by an Ingersoll approved specialist.
PRECAUTIONS
There are certain actions or environmental situations that may damage or
impede the ability of your timepiece to perform optimally. It is important to
avoid the following conditions: extreme heat or cold, as well as prolonged
periods of exposure to direct sunlight, exposure to wet conditions that exceed
the water resistance rating of your timepiece. Your timepiece should not be
affected by magnetic fields generated by household items such as televisions and
stereos, but it is recommended to avoid powerful electric fields or static
electricity, which may interfere with the mechanism. It is also important to
avoid extreme shock or impact.
