The screen on the igucci watch is blank and only the backlight is on. How do I get the time and date back on?

No, the display shows all the time. The backlight allows you to see the display at night. The manual states

1. Press 'D' or 'EL' in any mode to illuminate the watch face. The backlight will remain lit for 3 seconds. NOTE: EXCESSIVE USE OF LIGHT WILL SHORTEN BATTERY LIFE.

So basically, they are telling you to only use the backlight feature WHEN you REALLY need it!

Your watch is solar powered, so I think it isn't charged lately. At a low charge, the watch goes into saving mode by switching off the display (while keeping the time, date, etc.). To charge the watch leave it in a brightly lit spot for a day or two. That should be enough to make the watch function as normal again.

For more information, you can download the manual of your watch here (direct download link):

It's not the battery. It maybe the TM0501 board. GUCCI will charge you $450 to fix.

TO SET TIME AND DATE, PUSH SIDE BUTTONS TOGETHER OR AT SAME TIME TO MAKE THE SCREEN OR FACE OF WATCH APPEAR WITH ITS TIME OR DATE, THEN GO TO OTHER SIDE BUTTONS TO GO UP OR DOWN ON THE TIME OR DATE UNTIL YOU GET TO THE PROPER TIME AND DATE. THEN GO BACK TO FIRST BUTTONS YOU PUSHED AND PUSH THEM ONCE MORE TO GET OUT OF THE SETTING MODE.

Simple: from the default time screen. Push either of the right side buttons until you see settings.

From settings: Choose Watch.

From watch choose date set.

I don't know whether this is what you are looking for, as the watch comes with no packaged instructions OR general support, on their website, XD,

Armitron All-Sport Watch Instructions By Brian Walker eHow Contributor 9 Found This Helpful The Armitron All-Sport is a unisex style of watch made by Armitron that features a digital readout and four buttons around the outer dial for adjusting various aspects of the watch. It can set alarms, keeps the time as well as the date, and has a built-in backlight. Accessing and adjusting these various settings is a fairly simple process.

Setting Date, Time and Alarm

• To enter the date and time setting mode, press and hold the "mode" button, located on the top-left of the watch. Continue holding this button until the display begins to flash. This first display is the alarm setting, should you choose to set an alarm to go off. If you'd like to set the alarm, use the "alarm" button on the bottom-right of the watch to advance the hours to the desired one. Then press the mode button again; this will cycle through the minutes and seconds of the alarm to allow you to set those as well. Once you have set the alarm, you can press the "date" button at the top-right of the watch to proceed to the regular time setting. These numbers, which will now be flashing, also are adjusted by pressing the alarm button to change them. Pressing the date button again will now cycle through the hours, minutes, seconds and the date. As you continue to press the date button, the All-Sport will continuously cycle through these options; don't worry if you forget to set one, you can simply press the date button a few times until you get back to the setting you need to change. Once the alarm, time and date have all been set, you can press the mode button one more time to exit to the normal watch mode that will display the date and time.

Using Chime and Alarm

• The Armitron All-Sport features both an alarm and an hourly chime. The alarm function will cause the watch to continuously beep at the selected time until you turn it off by pressing a button. The chime will cause the watch to beep once every hour. You can turn both these features on and off by pressing and holding the alarm button and while holding it pressing the date button. The first time you do this, the chime will turn on and a small house symbol will be displayed on the watch face. Performing this button-pressing sequence again will turn on the alarm, which in turn displays a small clock icon on the watch face. Each successive pressing of this button sequence will alternate between the chime and the alarm, turning them either on or off.

Backlight

• The All-Sport also features a built-in backlight to help you view the watch in dark conditions. This light can be activated by pressing the "light" button on the bottom-left of the watch. Pressing this button is the only way to activate the light, and doing so will only cause the watch to illuminate for a few seconds at a time.

I took the watch back and exchange it for something else.

if this is the same as my watch, it's solar powered and when it gets TOO LOW< it will blank out and begin to charge .  Stick it in direct sunlight for a day if you can.  You can also stick it under a regualr lamp, but it will never get fully charged, but it should be enough to operate at least.  The battery meter is the top middle dial on the face.

I put a new CR2025 battery in my T5e671 Timex and it solved the problem.
The screen no longer goes blank at any time.
PS:Timex manual says "remove battery strap" to replace the battery.
But it doesn't say HOW.-& I couldn't google an answer to that.
Here is how:
The metal strap goes across the middle of the battery and then goes over the edge of it on both sides.
At both edges the metal strap goes over a nylon tab.
One of those nylon tabs is notched, if you put the end of a paperclip in the notch, you can release the metal strap edge that runs under it.

Try to use a piece of tape to cover on the battery, this is a way to do the insulation to prevent bad contact.
