I was in the process of changing the batter on my Victorinox Night Vision watch, when I noticed a small gold spring loose in the inside of the watch. I didn't touch anything but the battery and was being very careful during the process of removing the battery. I can't see anywhere obvious that the spring would have even come from, but I am freaking out a little bit because I love this watch and it wasn't cheap. I've changed many watch batteries before, but haven't had anything like hat happen to me before. I would take it to the watch repair guy in my town, but they are closed due to the pandemic. Any help is beyond greatly appreciated.

Does it go between the pusher and the movement?

That's what I was thinking, but I it doesn't seem to have a anywhere to sit. It can't just float in there, can it?

Hi  As JohnR725  remarked these springs are generally used as contact springs for the pizo disc alarm.  The analogue module looks like a ronda is there a caliber number on the movement.  Can you post a picture of the inside of the case back, there should be an pizo alarm disc(buzzer) attached .  Have a look at the inside on the back and look cor a contact mark it may help as to where the spring fits.

If you still haven’t fixed it, let me know what model it is or show a pic of the front and I will open one of mine up and look.

Typically gold springs like this are used if you have an alarm?

The watch does not have an alarm.

I can't read any of the engravings on the movement, other than to confirm that it is a ronda. I'd have to get a hold of a loupe or something.

They call it a Night Vision. The name is overhyped.

Thanks. I have one or two of those. I will open one up tomorrow. The analog movement will not be using it. It must have something to do with the light. Steve

Definitely do not have an alarm. But you do have a mystery I'm attaching an image one of the things that bothered me with his wide is the circuit board have that nice big around area that I circled? Plus it was hard to tell from the pictures it looks like it took more of it apart then you needed to? Not sure why it came apart as far as it did so give a mystery circle see if it connects to anything in between with a spring perhaps.

From research   the lower ronda  analogue movement powers the watch only,there is no connection to the upper module which uses the 3v battery.  This module is for the light functions only of which there seens to be several modes.     The black circuit cover that was removed does it have any contact marks on its lower surface which coincides with the round pad as noted by Joh725.  just a thought.

Well, fellas. The jokes on us, I guess. I took apart a NV I and a NV II, and there was no spring in either of them.

I have not taken off the black circuit cover, I simply lifted it while intact to access the lower area. I don't think it's possible that the spring came from in there.

Well... thanks for checking, I really appreciate it... I'm waiting for the replacement 370 battery to arrive from Amazon... I didn't know what the battery type was until I removed the case back, so I haven't been able to test to see what works and what doesn't (if anything). I was able to get a new 2032, and the pusher still makes the red indicator light go on, (so the spring is not required for contact), but I cannot turn the light on. I'm not sure if that is a function of not having the a battery for movement?

That begs the question from whence it came and surprisingly its been loafing around the case and created no problem untill now. Ah well mystery solved..

I hope you're right, but I'm never that lucky :/

Hi  do you by any chance have the users manual for the watch  as it explains all functions on the light module in there.     The number of button deppressions for each mode.

You can find some manuals here, including night vision.

thanks, gents. I have had the watch for quite some time and am familiar with the various functions of the light. It currently does not function as it should, despite a brand new battery. I'm hoping that once I get the movement working it might work somehow make everything right with the world. If not, I will hold onto this spring and maybe I just send the watch for warranty.

I owe you an apology and my thanks. I initially did not recognize the photo, as I had only opened that part up once, trying to get the old battery out. There was indeed, as you suggested there might be, a small hole in the black cover that held the spring and contacted to the circuit board in the place you circled. So thank you, thank you, thank you.

And thank you again to everyone who took the time to help troubleshoot this issue. The batteries I ordered from Amazon never showed up, so I finally went out and bought one today. That's why I haven't followed up until now, but I just changed the movement battery and reinstalled the spring. Now I have a watch that tells time and acts as a flashlight. yay me. and yay all of you. <3

    • Sorry @nickelsilver, I'm just seeing this now.  It is a standard metric screw plate. I followed the suggestion of doing the thread cutting in a pin vise.  It took me forever because the piece is so delicate that I cut and cleared chips very frequently.  But eventually I did get it.  Not pretty, but I got it; the first thing I ever successfully made on the lathe. I cut the screw slot with a jewelers saw.  How can I ensure that the slot is centered on the screw head?
    • Hello and welcome from Leeds, England. 
    • Hello, My name is David and I’m a vintage watch collector/ wanna be hobbyist watchmaker from France. I really want to progress into my watch repairing hobby. For now, I’m only having fun servicing my own watches and spare movements, simple small 3 hands from the 50s (Omega, eterna…) Learning step by step or at least trying to 🙂
    • More setbacks and successes...  After letting the watch run in (but before I fixed the BE) a chunk of the radium lume fell off one of the hands and pulverized leaving radioactive dust all over the dial 😞 ☢️ ☠️ So before I could continue further I decided I would remove the radium lume.  I have removed radium lume from hands before where it was already starting to flake away but this time I had to work out what I was going to do with debris on the dial.  I decided that getting everything under water and removing all the lume was probably the best way to go. So here is what I did... I put an essence jar I use for cleaning parts and filled it with water and put it into a big ziplock bag along with the tools I would need - a sharpened piece of pegwood and  a 0.80mm screwdriver  -  I put on a pair of nitrile gloves and a covid style mask and then opened the back of the watch. Now with the back off the watch I could do the rest inside the bag.  I removed the watch from the case and removed the hands from the dial (through the bag) and then undid the dial screws and removed the dial from the movement.  I then put the hands and the dial and the watch case into the water and removed the movement from the bag.  Carefully and slowly with one hand in the bag and one hand trying to poke and hold stuff through the bag I gently rubbed away the lume from the dial and hands with the pegwood. I then took the parts out of the water and removed the jar from the bag (leaving the parts still in the bag) - with the majority of the dangerous stuff now in the water I disposed of this (down the toilet) and gave the jar a good rinse in running water before refilling it and returning it to the bag where I gave all the parts another rinse in the new water.  I then took the parts and put the geiger counter over the top of them and looked at them carefully under UV light to see if there were any flakes still hanging on. I dried everything with some kitchen towel. Once I was finished will all that I remved the parts from then removed the gloves and put them in the bag with the paper towels and the pegwood and thew the bag in the household waste. Finally I gave the dial, hands and case another rinse in the sink under running water.  I didn't bother following up with a rinse in distilled water water because the water here is pretty clear of limescale etc and I find it doesn't mark! So here are the results of my weekends work! Timegrapher dial down (dial up is almost the same) The fixed shock setting New crystal - and lume removed from dial and hands
