    GW-400J gold springs

    I had my new (to me) GW-400J Silencer strap & bezel off for a soak to try & get rid of "smokers strap" when I noticed that the inner plastic bezel piece (adds the metal look) had come off. Much to my surprise, I found that there were 2 small gold springs (both about 5mm each) that fit in the upper screw holes (the back plate screw holes on top go right through - see pictures). Luckily, one of the springs stayed in the hole; the other "came out" & I was fortunate enough to be able to find it. Does anyone know what they are for? It would seem that they would fall out if you ever unscrewed the back plate, especially if you didn't know they were there. Are they supposed to be glued to the bezel & is the bezel supposed to be glued to the front? Things might be clearer looking at the pictures:

    Cool Re: GW-400J gold springs

    Might be 2 antennas för the waveceptor function. I know that the receiver is always placed on the top part of the case and those screws seems to fit that position. Another possibility is that they have some function for the vibration alarm.

    I would take a picture of the back of the bezel to see what they push up against. I'd think it's related to the antenna, as the vibration requires a weight to be spinning, and I don't think that would fit beneath the bezel.

    Hello,

    THose springs connect to a mechinism that uses the springs to gauge angle in order to turn the auto-EL on. This is how the watch magically knows when to turn the light on.

    If you don't ever need auto EL then those springs will bot matter much

    Cheers

    Leon

    Wish I'd known that BEFORE I spent about 30 minutes on my hands & knees with a strong light trying to find one that popped out into the rug!
    Thanks for the great information; another mystery solved.

    Magnet didn't work?

    Glad you mentioned this since I'll know to be careful if I open mine up.
