The moving mechanism inside gets stuck and i have to violently sheck the watch to get it lose and start working

If your Dango watch's second hand stops intermittently, there are a few things that could be causing the issue. Here are some possible reasons and solutions:

1. Low Battery: If the battery in your watch is running low, it could cause the second hand to stop. You may need to replace the battery in your watch. Check your watch's manual or take it to a watch repair shop to have the battery replaced.
2. Dirt or Debris: Dirt or debris can get inside your watch and cause the gears to stop moving properly. If this is the case, you may need to have your watch cleaned and serviced by a professional watch repair person.
3. Loose Second Hand: If the second hand on your watch is loose, it could cause it to stop intermittently. A loose second hand can be caused by a damaged pinion or cannon pinion. You may need to take your watch to a professional watch repair person to have it fixed.
4. Magnetic Interference: Magnetic fields can interfere with the movement of the gears inside a watch, causing it to stop or run erratically. If you have been around strong magnets or electronic devices, it could be causing the issue. Try moving your watch away from these devices to see if that helps.
5. Mechanical Issue: There may be a mechanical issue with your watch's movement that is causing the second hand to stop. This can be caused by a worn out gear or other component. You may need to take your watch to a professional watch repair person to have it fixed.

May be it's stuck mechanically?

If this is a self winding watch then you will have to rotate the pendulum inside it about 200 times before it will start. The directions should show you the proper way to rotate the watch to move the internal mechanism.

If the second hand of your watch isn't moving, but the watch is otherwise keeping time, you most likely have one of two problems. The simpler to fix problem is that the second hand might have come loose from the post onto which it's been fitted. It's a simple friction fit, and a watch technician would simply remove the watch movement from the case and very (very!) gently push down on the seconds hand to re-seat it. If that's the problem, that's all there is to the repair.

A second potential cause for this behavior could be that a speck of dust or crud has gotten into the gears that operate the seconds hand, preventing it from moving. This can easily happen when changing a battery--many watches tend to get somewhat of a buildup of crud where the watch back meets the case. Especially with screw back cases, the process of loosening the back also loosens the crud layer, making it easy for little bits to fall in. If you do have crud in your movement, you're a bit limited in what you can do. Unlike old-time mechanical movements, very few quartz movements are made to be disassembled and cleaned. Instead, a watch repairer may be able to blow some air (not compressed air from a can--that will probably wreck your movement) to try to clear the gears. If that doesn't work, there is a little device that some watchmakers have that runs your watch at about 50 time as fast as normal. Spinning the gears like that can sometimes generate enough force to clear a blocked gear train. I have done this to resurrect several watches whose hands were stuck. However, I was still able to see the "pulse" of the second hand on those watches, even if the hand itself never moved forward.

mcdevito75 here, BMW watch, nice watch, Actually there are 2 ways to start winding an automatic or self wind watch. Since you feel no resistance in the winder (crown) which if you did, would mean the automatic mechanism is attached by gear to the mainspring and winding the crown (stem) would start the winding process. Without any resistance winding the crown, your automatic mechanism is free-lance as a way of saying, in your watch which simply means your BMW watch winds solely on wrist / arm motion. First, make sure you hear the automatic mechanism moveing inside the watch when you move the watch in almost any direction, now simply hold the watch in your hand and with a rocking motion, say from 12--to 6 rock your hand back and forth for about 30 seconds. You can also make circular motions with the watch in your hand for 30 seconds, any motion that will cause the automatic movement in your watch to move will, start the winding process. After you see you watch has started, simply wear your watch to keep it wound.

It should still be under warranty.

If you have registered it or have a proof of purchase you should be able to have it repaired free of charge.

It sounds like a problem that can be solved by removing the mechanism from the case.

If the watch is within the warranty period your local dealer for that make should do it for nothing.

If it outside the warranty period, is probably best to let your local jeweler re-fix it.

Could be a number of issues but if the watch was closed correctly and hasnt gotten wet then it probably needs a dab of watch oil and a spin.

Everyday we get this issue. Customer gets new battery but the hands dont move. Its possible that its running electronically but not mechanically. As the watch ages the watch oil begins to lose viscosity and thickens and there is no torque in a watch movement so the hands wont move! So by adding a drop of oil and putting it on a clyclonic machine to force the hands to spin with a magnetic field it releases the stuck hands and the oil is released into the movement to lubricate the wheels! :-)

So, you should find a reputable watch repair business and have them recheck the battery and if they have a cyclonic machine then they should be able to see if the watch has that "beat" that comes off of the magnetic rotor! :-) If the o-ring or seal has been damaged and moisture has gotten into the watch then they can dry it out under a warm light with the case back removed and reoil the movement! Hopefully this will help!

You can also take it back to where it was purchased and they might be able to assist you with repair as well.

The battery you put in may also be defective to start with. You need to have a proper watch battery tester to know if the battery is actually good.

As for cleaning a watch the watch maker will take all the tiny mechanical pieces apart, put them in to a very fine screen basket, and submerge the pieces in to the cleaning solution inside of an ultra sonic cleaning machine. Once cleaned he will maliciously re-assemble all the pieces in back in to the casing structure and lubricate with the very fine 000 viscosity oil used for watches. Then he will perform all the necessary mechanical adjustments.

Personally, if not properly trained and not having the proper tools and jigs I do not think you would be able do this type of work without ruining the watch...

FIXED!!!

As it turned out these Mossimo ANA/DIGI watches use two different batteries, one for the digital part (big) and other for the analog mechanism (small).

Have the watch serviced to change the second battery and VOILA!!!!

Enjoy!
