Hello i just bought one of these watches and it didnt come with instructions..so how do i set this watch for the day/month/date? i need help with this...thanks!!!

Hello there, my condolences. the watch usually has 2 positions 1 for the day/date and the other for the time. you need to set your watch to the 1st position and move the crown forwards or backwards. but in other cases if you have only 1 position for the time then you must spin the time forward twice over to move it up one day. hope this helped you!

On that type of movement that are normally three clicks to the winder. One of then does Date when you turn it one way and Day when you go the other.

Thank you for contacting FixYa.

There should be four buttons: mode, reset, start and light. Find the mode button and press it three times until it is in the set time mode.

2 Find the reset button, which usually is located on the bottom right side of the watch face, and hold it until the time starts blinking.

3 Press the start button to change minutes.

4 Press the reset button again to switch to hours. You will know it worked when the hour starts blinking instead of the minutes.

5 Press the start button to change the hour. The watch can handle two modes: standard and military. As you press start, the hour will change from AM to PM, noted by an "A" or a "P" in the top right. When you get through 24 hours, the watch will change to military time and an "H" will be displayed instead of "A" or "P." Keep pressing start to go through another 24-hour cycle and it will revert back to standard time.

6 Press the reset button to switch to the date, starting with the month, and press start to change it.

7 Press reset one last time to switch from month to the day, and again press the start button to switch days.

8 Press the mode button to finish the changes.

The watch does not have a "perpetual" clock so it does not know what month it is in. It will treat every month as a 31 day month, so you will have to re-set the date anytime a month is not 31 days.

If you appreciate me answering this for you then please rank this solution as "fixya" or at least "helpful" as what I have said will solve your problem. :-)

Try pulling the stem out. Turn the stem in the counter clock wise direction and see if that changes the date/day
