The hour and minute hand are sliding around the face of watch every time I move my arm. The second hand is still moving correctly. Thanks.

Well, it is time for your lesson in "watch repair, 101."
Most all watches and clocks have the hands press on the various stems that stick out from the face.
There are usually 3.
The smallest diameter is also the longest, and is for the second hand. Next largest is between the middle shaft and the outer shaft, and is for the minutes.
The largest diameter shaft, usually the shortest, is the hour hand. Usually each hand presses on the correct shaft.
You'll likely need a magnifying class and a gentle touch.
God bless your efforts.

Setting Digital Time

1. The digital timepiece on a watch is set using the function buttons on the outer part of the watch face. To set the digital time, press and hold the upper left button until the seconds starts blinking. Press the lower right button to reset the seconds to "00."
   
   Push the lower left button to move to the Daylight Savings Time portion of the watch. Use the lower right button to toggle between "On" and "OFF."
   
   Press the lower left button twice. The hours unit will start blinking. To advance the hour, press the lower right button repeatedly until the correct hour is displayed. If you need to move the hours unit backwards, press the middle right button until the correct hour is displayed. When the hour is set, press the lower left button to switch to minutes, and use the same commands to change the minutes unit.
   
   After the time is set, press the upper left button to exit the digital time setting function.
Setting Analog Time
2. You may find after setting the digital timepiece that the analog display does not match. When this occurs, you need to set the analog time. To set the analog time, press the lower left button 6 times. Next, press and hold the upper left button until the digital time starts to blink. This indicates that you are in analog time setting mode.
   
   Analog time adjustment is completed using the lower right button. Every time you press the button, the analog time will advance 20 seconds. If you need to make a big change to the analog time, press and hold the lower right button to make the hands move faster. Once the analog time is set, press the upper left button to exit the analog time setting mode.

The best advice I can offer you is this.
Setting the Watch

Pull on the watch's knob, located on the right side of the face. It will pop out to a wider setting, one notch outward. This notch is the hour and minute setting for your watch. Turn the knob to move the hour hand, and set the proper time. Press in on the knob, against the spring, until you feel it hit the base. Wait to verify that your second hand begins moving, indicating that your watch is keeping the correct time.

On digital watches, press and hold the top button until the time begins flashing. Use the bottom button to move the hour and minute. Press the top button again to replace the new time and set your watch.

Repairs and Service

Keep your receipt and warranty paperwork in a safe location. This documentation will be important for repairs, resale and service. Visit your closest Diesel store for repairs requiring mechanical adjustments--or a trusted jeweler can handle the maintenance such as wristband alterations. Note that your Diesel watch may use links, held in place by small pins. These pins are best removed and adjusted by a jeweler or watch technician, so as not to damage the quality and value of your watch.

mcdevito75 here, Sounds like your Guess watch neds some service, cleaning, oil etc. You can check with the repairservice directory right here at fixya, bottom of this page click on repair service directory then watches.

It could have 2 batteries! 1.5 volt for analog and lithium for digital! Take it to a reputable watch repair business and let them check! :-)

Good luck!

If the hour and minute hands have also stopped, then the watch needs a new battery (if it is electric), or needs to be wound (if it is mechanical or automatic-mechanical).

If the hour and minute hands are still functioning and telling the correct time, then the second hand has become loose and needs to be re-attached. A watch repair shop can do this for you and it should not cost much.

go to Buliva web site and look for the chorograph 561/598
FEATURES
1. Hours, minutes, seconds and date display.
2. 60 minute Chronograph (CHRONO) with minutes and
seconds display.
3. 24 hour hand, permanently synchronized with the normal
12 hour hand.
A. SETTING THE TIME
1. Pull the crown out to position “3” (See diagram). If the crown has
a “screw-down” lock, then unscrew the crown lock first by turning
the crown toward you, then pull it to position “3”. Do not forget to
screw the crown back “IN” after all setting is completed.
2. Turn the crown towards you (hands moves clockwise) until the
date changes at approximately midnight.
3. Continue turning the hour and minute hands to the correct time.
If it is afternoon you must go past 12 o’clock again (noon) to set
the correct time.
4. When the correct time is set,push crown back to position “1”.
B. SETTING THE DATE
1. Pull crown to position “2”(See proceeding diagram).The watch
will continue to run.
2. Turn the crown away from you until the correct date appears.
3. Once the date is set, push the crown back to position “1”.
Note: Do NOT set the date between the hours of 8:00 PM and
3:00 AM.This would not damage the watch,but the date may need
to be reset later.
C. CHRONOGRAPH (CHRONO) ADJUSTMENT
If the chrongraph second hand is not positioned at the proper
starting position (12 o’clock or “zero” position), use the below
procedure.It does not need to be repeated unless the watch
receives an impact sufficient to move the hand out of position, or
the Battery has been changed.
1. Pull crown out to position “3”.
2. Push button “A” to move the Chrono Second hand (long hand) to
the “0” or 12 o’clock position. Each button push will move the
hand one step – BUT holding the button down will advance the
hand rapidly.
3. Push crown back to position “1”.
D. USING THE CHRONOGRAPH (CHRONO)
Note: The maximum chrono reading is 60 minutes, However the
chrono will continue running once 60 minutes has passed. The
resulting one hour periods may be added together mentally to keep
track of longer periods.
For example – If you know that approximately one hour has
passed since you started the chronograph, and the chrono reads
25 minutes, then you know that the chrono has been running 60
minutes plus 25 minutes, which is one hour and 25 minutes.
1. Push Button “A” to start the chronograph. Push button “A” again
to stop the chronograph.
2. Push button “B” to return the two chronograph hands to the
“Zero” or starting point.
3. The Chronograph can be stopped and started again
(Button “A”), repeatedly, to “ADD” times together.
