Silicon scientific atomic watch

The Invicta Atomic 4048 is "discontinued", and Invicta is not very helpful. They do NOT offer an instruction manual for the 4048, because it's discontinued. You can call Invicta at 800-327-7682 then you have to ask for "Melvin" who only works until 1PM eastern time. OR you can do the following:
Hold down the 8 0'clock button until it flashes, select 12hour or 24hour preference, use the button at 4 o'clock to select your time zone (GMT) The watch should reset itself to your GMT time.

1. In the normal time mode, Press MODE key to enter the alarm time mode .
2 Press SET key to change the time zone, P is pacific, m is mountain c is central and e is eastern.

mcdevito75 here, You re-set the time in a different time zone the same way as you do for the time zone your in now. The different time zones in the USA ru from 1 to 3 hours before the time in the Eastern part of the USA, example, Eastern time 3 PM, then going West, you have Central time 1 hour before, then Mountain time, 2 hours before , then Pacific time 3 hours before eastern time.

I have one of these, and look for the manual on the 'Net every time DST changes, and eventually figure it out. Here's how: (1) Hold down the ALM/SET button until you get past the alarm setting and you see 24H or 12H. (2) Step through the settings by pushing the ALM/SET button, changing each as desired by pressing the +/CYCLE button. Eventually you'll wind up with the time zone indication flashing (it's really tiny, and appears just below the time indication). Press the +/CYCLE until you get to the desired time zone. (3) After the screen quits flashing, press the -/DST button to get the desired setting. I hope this helps, and that I can find this post again next time change!

You should be able to set your watch to the Pacific time zone.

f you haven't got instructions on how to do this, you can get
instructions from the Casio web site.

The "mode" button is there to change the function of the + & - buttons.

If you press the mode button several times you will cycle through the various setting features of the clock.

Look for the one that sets the time zone and use the + or - buttons to select your zone.

Some experimentation may be required!

This watch automatically sets itself. I you live in the eastern time zone, you just have to wait for the watch to receive the signal then it will set itself to the correct time & date. The signal is strongest at night between the hours of 10:00 pm & 2:00 am so it normally takes over night to set. Sometimes the weather interferes with the signal so I tell people to give them a couple of days to pick up. Also if you are having trouble receiving the signal try placing the watch by a window. If you do not live in the eastern time zone try these instructions:

Hold down the button for 2 seconds until the time zone abbreviation & zone flash the keep pressing the button until your correct time zone is displayed. Then wait about 8 seconds for the watch to return to normal display. Then you just have to wait until it picks up the signal & sets itself. I hope this helps.
