Replacing the battery and resetting:
1. Turn the watch over and place it face down on a soft cloth. Remove the four screws and the plastic back.
2. Using a fine pair of forceps (I have a selection of those stainless steel ones) remove the rubber o-ring that seals the case and gently tease out the movement from the case. You can replace the battery without removing the movement but I found it easier if it was out of the case; however you have to be very careful to avoid damaging the hands.
3. Place the movement face down on a flat surface; I used a block of cork. Make sure 12-o’clock on the watch is away from you at 12-o’clock.
4. Unclip the battery retaining spring at the 6-o’clock position and tease out the battery towards you using forceps. Temporarily remove the label that tells you to make sure of the battery polarity is +ve up and to short out the battery –ve terminal and the “ATM” (presumably automatic timing mechanism) otherwise you can't see what you are doing.
5. Using the forceps short out the battery –ve terminal, which is a flat leaf spring with 3 prongs at about 4/5-o’clock in the battery compartment and the ATM, which is a recessed small metal button in the very centre of the compartment. If you don’t do this you won’t be able to get the second hand fast-running and it will do one circuit and then stop.
6. Replace the battery (+ve up) and the label. Gently replace the movement in the case; there is a small notch at 12-o’clock that aligns it. Replace the label and the o-ring and screw on the back making sure the o-ring is in its groove.
7. Turn the watch over face-up. Press and hold the S1 button (top right button) until the second hand start to run quickly and then release it. Wait until the hour hand is on 12-o’clock and the minute hand is about 0:59 and press S1 again. The second hand will stop. Briefly press S1 and the second hand will advance a second at a time. Do this until all 3 hands are at 12-o’clock. DON’T GO PAST, or you will have to start again.
8. Press S4 (lower left button) to confirm. The LCD then comes up with the time zone and city etc. The rest is in the instructions and the watch should pick up the time signal and reset itself. The important bit is to short out the mechanism and to get all 3 hands to 12-o'clock.
