I need to know how to set time and date i lost the instructions. Can you help?

I would find the company on line, there should be manuals, or tech support, they can sent it email

Here's how you set the 40/6623 M175 for anything. I figured it all out with help from here :). Okay so want to set the alarm? Press MODE once. Then hold it. And use the DATE and ALARM buttons to set the alarm. Press MODE twice and you're done. To set time do the step before this and press MODE once. Use the DATE and ALARM button to set the time. As for the 24 hr deal what you do is hold ALARM and press MODE or hold MODE and press DATE. To turn alarm on/off hold ALARM button and then press the DATE button. To set the date go to time set mode and keep cycling between the hours and mins until you get to the date :). That's all you gotta do :D. I know many of you need the instructions so here it is!!

Hi an_stocker0,
There is two pulls to set the time and date .First pull is for the day / date wind it in order to choose the right date number and second pull is for the time wind it until the desired time comes out. For better understanding follow this link for more information and instructions below. Feel free to ask whatever the results.

You can get instructions from the Timex web site "timex.com".

At thebottom of the screen click on "manuals/downloads", then on "product
manual download"

Enter your watch type in the search box and click on "search"

the instruction aren't much help either. this was a watch they discontinued pretty shortly after they released it. poor instructions and poor usability. great watch company though. this one was just a dog.
this was taken from a page off amazon: "Try to use the following for setting. 

Press/hold with the upper left button until LIGHT OFF on the display. 

Use lower left to select hour, min, date........ 

Use upper/lower buttons for adjust hour, min, date...... 

Press upper left to exit setting." 

it worked for me. i have several of their watches, but like i said, this one was one of their "dogs"

Hi go to www.casio.com/support under technical support choose manuals.

hi i had the same problem but i have just found the answer. hold the light button until it flash's 12 or 24, then press mode which will change you on to the time, date, ect then fiddle around with the start and reset button to toggle with the time and date. when your done with the time press light again.

for a watch face that has a day of week, date, and moon calendar: There are two click points on the set-pin. pull out 1 click to access date/moon calendar; spin clockwise to set the moon calendar. spin counterclockwise to set date.

pull out pin 2 clicks to set time, just like any other watch

Alot of times on watches you can click on the stem one time and you can change the hour. Click on the stem and you can change the minute, date, and month.
