it off before using the watch. If the watch is used with the film on it, dirt, sweat, dust, or moisture may be attached to the film and may cause rust.

b WARNING

When diving, never carry out operations other than those specified in this instruction manual. Mishandling of the product and misunderstanding of the displayed content may lead to a fatal or serious accident.

WARNING

The diver’s watch is an auxiliary instrument which mainly displays the passage of time and does not ensure the safety of a user. Use this watch while using the equipment (residual pressure gauge, water depth meter, etc.) required for safe diving.

WARNING

Never use this watch for “saturation diving” using helium gas.

WARNING

Do not dive using this product unless you have been properly trained in scuba diving, acquired the requisite experience and techniques for safe diving, thoroughly familiarized yourself with the operation and handling of this product, and inspect all functions of this product prior to each dive.

b CAUTION

Inspect the following items before diving (excluding saturation diving):

• The watch is normally operating.

• The remaining battery level is sufficient and the mainspring is sufficiently wound.

• The rotating bezel turns smoothly. (The bezel rotation must not be too loose or too tight.)

• Screws of the crown and other parts are reliably tightened.

• No abnormalities such as flaws or cracks exist on the band or glass.

• The band is reliably fixed (with spring bar, buckle or other parts.)

* If any abnormality is observed in the above items, do not use this watch for diving.

b CAUTION

Do not operate the crown or buttons underwater.

CAUTION

As the use environment of the diver’s watch may affect not only the case or band but also the internal mechanism of the watch, we recommend that you periodically request an overhaul for inspection and adjustment approximately once every three to four years.

This watch is equipped with water resistant performance to be used in water for a long period of time with scuba diving tanks. (It cannot be used for saturation diving that uses helium gas.)

The calendar is a fully automatic calendar with dates from 2001 to

2100. The day and date are displayed on the digital display screen.

You can display your home time on the analog display and the local time on the digital display.

The stopwatch can count up to a maximum of 100 hours.

The watch is equipped with a daily alarm function that sounds every day at the set time (hour/minute).

The watch charges by converting light that shines on the solar panel on the dial into electrical energy. After the battery is fully charged, the watch will operate for about six months even if the dial is not exposed to light.

If the dial is not exposed to light and the crown and buttons are not operated for a certain period of time, the power save function activates to limit the consumption of unnecessary energy.
