I have a Springfield Precise Analog battery powered clock. The time zones of ST, ET, CT, MT and PT are selectable along with DST. What does DST stand for? Is it Daylight Savings Time as I suspect? It that's the case, how does the clock know which zone it is in?

The correct time zone setting for Arizona on this watch is YEA (Edmonton International Airport). Hold the adjust button for several seconds until the three code time zone starts flashing, then use the forward/back buttons to select YEA.You need to keep the DST mode off, so press mode once, then the forward button to select off in the DST select screen. From there, you can then press mode to manually adjust each time/date area individually. The final thing that you can adjust is the language, choose ENG for english. Press adjust to keep your settings, and you should be good to go.

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!

It looks like daylight saving time (DST). You can reset your watch to turn it off.

If you haven't go any instructions on how to do this, you can get instructions from the Casio web site.

Go to the casio web site "casio.com".

Select "support" and the "manuals", watches;

Accept terms

Select "watch manual archive"

Read the number of the back of your watch and enter it into the search box

It may be set to DST (daylight saving time), see instructions for changing this.

I have a different model of Casio but I suspect that the operation is the same.

To change DST you should press the button (8 O'clock) to give world time. This should be showing your city.

You should then use the button you mention to toggle between DST & ST. (ST is no DST display!).

If this does not work and you wish to read through instructions for your particular model, then go to casio.com, select "support", and under "technical support" select "manuals", then "watches", agree terms, and the select "watch manuals archive", insert the required number off the back of your watch and download the instructions.

You posted this in January, which is not during daylight savings time. The SMT setting doesn't turn on automatic DST switching for a particular timezone; rather, it is a manual override to adjust timezones to DST when it is actually active. There is no automatic DST adjustment for this watch (according to their FAQ). Turn SMT to OF for all timezones during winter months, and ON for applicable timezones during SuMmer Time (SMT).

I just bought a 4756. Hard to follow that manual.

In the end I used these parts of the manual
Step 1 was to set the correct time zone (off PT or pacific time to ET eastern Time.)
Step 2 was to do a manual receive of the radio time.
Step 3 was to Home all the analog hands so they all pointed to 12. see manual
Step 4 then I hit B button - top right by the 2 and everything spun around to the right time received from the manual received time.
