Should be 4 buttons, 2 on left and 2 on right. Press bottom left 3 times and hour offset digit will be displayed. Press and hold top left until hour offset digit starts to flash. Press either top or bottom right to adjust offset hour to correspond with your time zone. Eastern -5, central -6, mountain -7, pacific -8. These are negative numbers, not positive. Then press top left button once, then press bottom left button to return to time display.

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.

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!

how to change hour number for setting clock back

After a bit of searching I found a makers name for you. I trust that this is the make you have (I doubt if there is more than one!)
If you go to "www.accessible-devices.com/reizen.html", this is an instruction sheet for Reizen talking watches.

Unfortunately no. You will need to try contacting Invicta direct. Sometimes you can go to Invicta retailers and they will have some left over or they will have instructions for similar models.
