That depends on the make / model of the watch.

Most mechanical watches, and some battery operated analog watches have a knob that can be pulled out half way, to set the date, and all the way, to set the time.

Most digital watches have at least two buttons: one (I'll call "A") for setting the mode, and "B" for incrementing some value.

Typically, one presses A briefly, to cycle the display through "clock, calendar, alarm, chronometer etc".

By holding A for a few seconds, likely, something will start to flash. This indicates setting mode. Pressing A briefly again, will cycle through seconds, minutes, hours, day of month, month, and possibly year. (perhaps in opposite order). Pressing B will increment whatever number is flashing. Holding A again, will save any changes, and return the watch to normal mode.

Adjust the day of month (1-31) by pulling the crown pin out part way, and turning the pin counter clockwise, incrementing the date arm. Counterclockwise does nothing.

To adjust day of week (Mon-Sun), pull the pin out and rotate to turn minute/hour hands. Each time you pass 12:00, the weekday hand will increment by a half step.

The crown has 3 positions.

Normal screwed down.
First pull out position.
Second pull out position.

Setting the Time:
Pull out the crown to position 3.
Rotate the crown to set the exact time.
Ensure that you are in the daytime12 hour segment by allowing the hands to pass 12 o'clock and notice if the date moved on or not.
If the date changed, then you will need to advance at least 2 hours before moving on to set the date.
If you do not need to change the date, return the crown to position 1.


Setting the Date:
DO NOT DO THIS IF THE WATCH IS BETWEEN 8pm & 2am
Pull crown to position 2.
Rotate the crown clockwise to set to the correct date.
Return the crown to position 1.


Setting the Alarm [12 hour]
Pull the crown to position 2.
Rotate the crown anti clockwise to move the alarm hand to the desired time.
Return the crown to position 1.
To activate the alarm, press the 8 o'clock button. You will hear 2 beeps.
To deactivate the alarm, press the 8 o'clock button. You will hear 1 beep.
NB If the alarm is not cancelled while it sounds the first time, it will repeat again in 2 minutes time. The alarm sound last for 15 seconds. If the alarm time coincides with 1 beep of the countdown, the alarm function will be cancelled.


Battery EOL [End Of Life]
The Swiss ISA 8270 movement uses a 395 cell and will signify a low power state by advancing the small seconds hand 4 steps every 4 seconds.


Setting the Countdown
You can specify a countdown of between 1 and 10 minutes.
Press the 4 o'clock button to enter setting mode. You will hear 1 beep.
Press the 4 o'clock button to move the central timing hand successively to the desired countdown time.
Wait 3 seconds for the watch to automatically exit the setting mode.
You can change the duration of the countdown [except in the last minute] at any time.
e.g. If the countdown is set to 10minutes, and you now want to change the countdown to 9 minutes, press the 4 o'clock button. The hours/seconds counter sub-dial will perform one complete turn and then stop at 60, before continuing.


Activating the Countdown:
Press the 2 o'clock button to start the countdown. You will hear 2 beeps.
The hours/seconds counter sub-dial will perform one complete turn and then stop at 60, before continuing.
When the countdown begins, the hour/seconds counter sub-dial indicates the seconds with 1 step every 2 seconds, and the central timing hand indicates the minutes with 1 step being 2.4 seconds.


Countdown tone:
There are 2 beeps every minute.
in the last minute:
50 seconds=1 beep.
40 seconds=1 beep.
30 seconds=2 beeps.
20 seconds=2 beeps.
10 seconds and less=1 beep every second with zero being 1 second long beep. Timer function automatically starts.


Timer:
After countdown has finished the timer starts automatically.
The central timing hand indicates the minutes with 1 step every 12 seconds. The hour/minutes counter sub-dial indicates the hours up to a maximum of 96.
Press the 4 o'clock button to see the timer seconds [display lasts up to a minute].
Press the 4 o'clock button to see the timer hours.
The timer has a maximum time of 96 hours [4 days] after which the hour/seconds sub-dial counter will stay at 0 and the central timing hand will stay at 12.


Start/Stop Timer:
Press the 2 o'clock button to stop the timer. You will hear 1 beep.
Press the 2 o'clock button to resume the timer. You will hear 2 beeps.

Setting the Timer:
Press the 2 o'clock button to stop the timer. The hour/seconds counter sub-dial will show the elapsed hours and the central timing hand the elapsed minutes.
Press the 4 o'clock button to view the seconds elapsed on the hour/seconds counter sub-dial.
Press the 4 o'clock button to reset.


Resetting the Hands:
If the hands do not zero correctly, which might occur after a battery change or a violent shock, you can make adjustments by doing the following settings as long as the countdown is not in operation.
To correct the hour/seconds counter sub-dial, pull the crown out to position 2 and wait 1 second.
Press either the 2 or 4 o'clock button; the central timing hand will turn and stop [not necessarily at 12].
Press the 2 o'clock button to increment the hours/seconds counter sub-dial hand to position it at 60.
To correct the central timing hand, press the 4 o'clock button to increment the hand to the 12 position.
Return the crown to position 1.



If the battery had been replaced, the central timing hand defaults to the 10 minute position. If the battery had not been replaced, the central timing hand will return to the previously set position.

You would have to remove the movement from the case, remove the hand and reinstall it, to where you want it.

hi,
By trial and error, you need to press and hold one of the buttons until the face blinks. That means the interface is in "set" mode. Once you're in set mode, then there are two options: increment the element that's blinking (hours, minutes, etc), or move the focus to the next element. These two actions are probably handled by two different buttons. The button you initially held probably does the focus shifting while another button probably does the incrementing.

"Set" mode is like a tunnel. Once you're in, just keep moving focus from element to element until you run out of things to change, at which point you exit the tunnel and return to normal watch mode.

Hi Johny

It is possible to set the main analogue hour and minute hand 30 minutes out of phase with the digital readout, but doing so will also put the analogue UTC dial 30 minutes off. It can be done by using a variation of the proceedure for zeroing the watch hands as follows: 1. Rotate the crown in its normal opering position to set the watch in chronograph mode (mode dial pointing to "chr") 2. Pull out the crown to the second click. This should cause all the hands on the watch to return to zero. "HR" should appear on the left-hand digital display. This will allow you to move the hour hand by twisting the crown. Advance it to about half way between the 12 o'clock and 1 o'clock positions. 3. Press the top button. "MIN" should appear in the left-hand digital display. This allows you to adjust the minute hand. Twist the crown to advance it to the 6 o'clock, or 30 minute, position. Note that this will also move the minute hand on the small UTC dial to the 30 minute position. 4. Press the crown back into its normal position. 5. Reset the digital time and date according to a time zone that is in a one-hour offset from UTC. This is not a perfect solution. Your digital readings will show the correct time for all one-hour offset time zones while your analogue nads are 30 minutes out of phase. Your small UTC dial will also be 30 minutes out of phase with the digital UTC. Hope this helps.
