Luminox 3100 series watch stops at night.

If any battery operated watch starts losing time or displaying the incorrect time, this is usually indicative of a battery going bad and needing replacement. My Luminox 3100 started lagging in time and I noticed that the second hand would intermittently stop. I also have a Suunto Vector (Digital) wrist-top computer and the times along with the compass, altimeter, light and alarms all started to act crazy and all it happened to be was the battery being run down. Coincidentally the Suunto has a battery gage that only appears and flashes during low battery charge.
BL: Try the simplest thing first, change your battery. Please be very careful not to break the O-ring on any watch that's waterproof/resistant as this will render the protection useless. Also if your watch is still under a manufacturer or vendor's additional warranty, get them to change it as not to void your warranty. 'Hope this helps!

you set it using the wheel pull it out , it should have two positions, one adjust time the other one date and chronograph, I see if I find full manual.

Hi,

It sounds like the setting mechanism has gotten out of place or is bent. A qualified watchmaker can fix this for you.

Hope this helps,

it has a screw-down crown, you have to turn it counterclockwise until it pops looses slightly, then you can pull the crown and set time...dont forget to push and rescrew it down to case to keep it water tight :)

On some watches - scuba usually - the crown has a rubber seal and that seal is engaged when the crown is screwed to the case. If your watch is like this, you need to unscrew the crown before you can pull out the stem. Twist the crown in a counterclockwise direction several turns. You will be able to tell when it is completely unscrewed because youwill feel spring tension. Pull out the stem to set the watch. When you finish, push the stem back in. Push against the spring tension and carefully thread the crown back onto the case. That should do it.

parsecent.com...they have all the parts to fix it with and they also have to band-to-case piece that you've lost

Sounds like there could be a bit of foreign material floating about inside, or the new battery was not up to scratch. Take it back for checking.

If you have your instruction manual it should tell you how to reset the chrono. i have the Luminox 8352 and it says to pull the crown out to the 3rd position. then press and hold both the start/stop and lap/reset buttons for a couple of seconds. you'll see the second hand rotate, then you can single click the start/stop button to manually move the second hand 1 second, or you can hold it and it will continue move for a longer period until time desired. if you need to adjust the other chrono hands, click the lap/reset button and then you can click the start/stop button again. repeat for the minute/hour chrono hand. when you're finished push the crown back in. it might work even though it's a different model, worth a shot? hope that helps. these are really great watches.

If you dial in the date before noon make sure you stop winding the crown right after the date flips. That will give the internal mechanism the most room to cycle and not flip at noon. If you are setting it after noon wind the crown just until the date you want starts to move to the following date, but stop immediately after so as to not flip over. That way the mechanism will be close to changing the date and should flip it at midnight. Make sense? Hopefully, good luck.

Because of the way they work, it's quite hard for quartz movements to run consistently slow - so if you find one getting behind, it's usually a sign that it's stopping intermittently. It would do no harm to check that the crown is properly pushed in after you've reset it, but my guess is that the watch will benefit from a new battery. A.
