FEATURES

Cal. V137A is an analogue watch with a solar power generation system.

l Solar power generation system

The watch operates while charging electricity by converting light received on the dial to

electrical energy. It lasts for 6 months after full charge.

l Energy depletion forewarning function

When the energy stored in the rechargeable battery is reduced to an extremely low level, the

second hand starts moving at 2-second intervals instead of the normal 1-second intervals.

Cloudy weather/Sunlight 10,000 30 hours 1.2 hours 8 minutes

Fair weather/Sunlight 100,000 10 hours 0.1 hours 1 minutes

The above table provides only a general guideline.

It is recommended that the watch be charged for as long as the charging time according to the

column "Time required for steady operation" in this table in order to assure the stable movement

of the watch.

l Caution for charging

When charging the watch, do not place it too close to a photo ﬂash light, spotlight, incandescent

light or other light sources as the watch temperature will become extremely high, causing damage

to the parts inside the watch.

When exposing the watch to sunlight for recharging, do not leave it on the dashboard of a car, etc.

for a long time, as the increase of watch temperature to an extremely high level can damage watch

parts or cause malfunctions.

While charging the watch, make sure the watch temperature does not exceed 60 °C.

• DisassemblingandReassemblingofSOLARCELL

* Do not apply excessive force to the SOLAR CELL.

* Just like COIL BLOCK, SOLAR CELL gets damaged easily by static electricity. Be careful not

to get it magnetized, especially the part where it touches CONTACT POINT SPRING.

As there are 2 connection parts of the HOLDING RING FOR DIAL, release them side by side.

Set the SOLAR CELL to 2 guide posts, and assemble

it to the HOLDING RING FOR DIAL by gently pushing

the hooking positions of the SOLAR CELL as shown

by the arrow marks in the illustlation.

7 CONTACT POINT SPRING FOR SOLAR CELL

Set 3 pcs of CONTACT POINT SPRING FOR SOLAR CELL at the

correct position as shown in the illustration.

Note: While other solar movements normally use 2 pcs of

CONTACT POINT SPRING FOR SOLAR CELL, 3 pcs are used in

Cal. V137. The third piece is assembled to keep the metallic part

under the SOLAR CELL in positive potential in order to stabilize

the watch’s performance.

9 DATE DIAL GUARD

1. Lightly lift the A portion of the date dial guard with

tweezers to release it from the guide pin, and then move

it in the counterclockwise direction to put it on the guide

pin.

2. Release the B portion of the date dial guard in the same

way as described above.

3. Check that all the three hooking portions of the DATE

DIAL GUARD have come off from the MAIN PLATE, and

then remove the DATE DIAL GUARD.

1. Put the DATE DIAL GUARD on the MAIN PLATE so

that the A and B portions are over the guide pins, as

shown in the illustrations at right.

2. Move the portion D in the clockwise direction so that

it is caught under the MAIN PLATE.

3. Slightly move the portions C and E in the clockwise

direction alternately to set them under the MAIN
