Master Chief Posted June 21, 2008 Report Share Posted June 21, 2008 When I fix a bolt with a nut, the bolt turn round and round....the screw is loose and I can not tighten it firmly. Joshua said that using 'locktite' will be solve this problem. but I'm really worried about it. Is using 'locktite' the permanent solution? Maybe you can give me some advice.

docblackrock Posted June 21, 2008 Report Share Posted June 21, 2008 If that's the screw just behind the fliplock clasp, then if it's any consolation I've had a similar problem with my 116710. Worked loose a couple of times and prevented clasp opening. But it threads in not stripped like yours. Loctite works well, age-old-remedy to thread-lock screws, just be sure to use the correct type - blue/removable. Quote Link to comment Share on other sites More sharing options...
Dizzy Posted June 21, 2008 Report Share Posted June 21, 2008 looks like a movement holder screw and sounds like its stripped. No lock tight wont do anything in that case. Might have to epoxy it in place somehow, but be warned.. epoxy and messy and perminant. edit - sorry i just looked at the pic again and its a bracelet link.. monitor was dark and only saw the flat shiney top. locktight still wont be 100%. i would try to replace the link with another one if you can. If not then i would use a drop of glue in the thread holes then screw the screw in and let it sit for 24 hrs to dry. dizz Quote Link to comment Share on other sites More sharing options...
docblackrock Posted June 21, 2008 Report Share Posted June 21, 2008 Dizzy makes a good point, before you start messing round with adhesives, I'd try swapping out with bracelet screws from other links first, start with your spares (the bracelet would fit a 10" wrist!).

Master Chief Posted June 21, 2008 Author Report Share Posted June 21, 2008 Docblackrock & Dizzy! Thanks for your advice. I will try it both way.

freddy333 Posted June 21, 2008 Report Share Posted June 21, 2008 I had the same problem with the same screw on my GMTIIC. Loctite blue fixed it. Quote Link to comment Share on other sites More sharing options...
Dizzy Posted June 21, 2008 Report Share Posted June 21, 2008 yeah locktite BLUE is basicly adhesive. I think you could prob get the screw out if you had to later on, but you would need to heat up the link first to melt the locktiite. the nice thing about locktite is that it stays rubbery and doesnt get dry and brittle so it may hold the screw longer than some random adhesive. good call freddy. dizz Quote Link to comment Share on other sites More sharing options...
Tom Hawkes Posted June 21, 2008 Report Share Posted June 21, 2008 Well, I never had to heat something up with loctite blue. If you carefully unscrew, there shouldn't be a problem, imho. Quote Link to comment Share on other sites More sharing options...
Dizzy Posted June 21, 2008 Report Share Posted June 21, 2008 isnt locktight blue the one that needs heat for removal? Maybe ive got it backwards Quote Link to comment Share on other sites More sharing options...
Sir-Lancelot Posted June 21, 2008 Report Share Posted June 21, 2008 heat would make it easier, but if you use firm steady pressure it will come loose on it's own. Quote Link to comment Share on other sites More sharing options...
magagne Posted June 21, 2008 Report Share Posted June 21, 2008 I had the same problem with the same screw on my GMTIIC. Loctite blue fixed it. Loctite 242, the one on left side? Please Fred comfirm Quote Link to comment Share on other sites More sharing options...
freddy333 Posted June 22, 2008 Report Share Posted June 22, 2008 Loctite 242, the one on left side? Please Fred comfirm Yes, medium strength (blue). If you have a tube of silicone sealant (used to seal water leaks around windows, etc.), that will work also. Any type of glue that remains pliable & does not form a permanent bond with metal should work. Quote Link to comment Share on other sites More sharing options...
Master Chief Posted June 22, 2008 Author Report Share Posted June 22, 2008 (edited) Thanks for many advice Today I search internet, and bought this one. Loctite 268, red stick, more high intensive glue , and Loctite 248 blue stick is below. I'm not sure what loctite is best solution.. just try it!

FxrAndy Posted June 22, 2008 Report Share Posted June 22, 2008 242 or 248 should be perfect they are designed to hold screws in place where they may need to be removed later with out the use of power tools, 272 on the other hand is for tighter application where you may need to use power tools, so dont use it unless you have a real small screw driver for your impact driver Quote Link to comment Share on other sites More sharing options...
Guest carlsbadrolex Posted June 22, 2008 Report Share Posted June 22, 2008 Just an FYI... When I took two links out of my Z serial 16610 there was adhesive on both link screws. It was white and not blue, but very obviously an adhesive of some sort. And I also have an issue with that very same screw. I will loctite mine tomorrow. As an aside, has anyone noticed that the bezel insert is not aligned properly on their GMT IIc? Mine is about 1/2mm off to the left so that aligning it means turning back between clicks. If it were any other watch, I would pop the bezel off and re-align it. But Im afraid I might crack the insert in the process. And something tells me these inserts arent going to be available.

I noted the same bezel misalignment a couple days ago, so I guess it is a (minor) design problem & not a defect in my watch. There seems to be a bit of play in the centering mechanism, which I think is the problem. The white material you see on some link screws may be GC crystal cement, which alot of watchmakers use in place of loctite because they always have it on their bench. Unfortunately, GC is not intended for use in moving parts, so it does not last very long. Loctite (blue) always works with these screws for me.

Tom Hawkes Posted June 22, 2008 Report Share Posted June 22, 2008 I was talking about the blue one (248). Unscrewing without heating up works for me. Quote Link to comment Share on other sites More sharing options...
