316L Posted August 18, 2007 Report Share Posted August 18, 2007 4.33mm thanks, but never, for the tube hole you need a driller of 2,7-3 mm. Quote Link to comment Share on other sites More sharing options...
Guest avitt Posted August 18, 2007 Report Share Posted August 18, 2007 thanks, but never, for the tube hole you need a driller of 2,7-3 mm. That may be correct to actually drill the tube hole...But we were answering the original poster's question regarding which size bit to use to countersink the hole.

freddy333 Posted August 18, 2007 Report Share Posted August 18, 2007 Sorry, I was going to add that the exact size for this bit is not that important since you are only countersinking and NOT drilling all the way through. The countersink is like a circular indentation around the actual hole where the tube sits so the crown can screw all the way down on the tube and fit to the case properly.

cableguy Posted August 18, 2007 Author Report Share Posted August 18, 2007 hmmm it didnt go so well.....i guess the hole was too close to the bottom of the case? this was a so called perfect sub case (ETA Noob) anyway to avoid this next time? or am i out of luck.... I have one more Noob case that is the same Quote Link to comment Share on other sites More sharing options...
Guest avitt Posted August 18, 2007 Report Share Posted August 18, 2007 That case can't be countersunk very much at all. The case is too thin, and the tube hole is biased towards the bottom. If you try this again, drill very gradually, until the cut approached the outer edge of the case...then stop. Also, make sure that your bit stays centered in the hole. Good luck.

cableguy Posted August 18, 2007 Author Report Share Posted August 18, 2007 ^ ok cool...how does one go about getting the crown to fit up against the case then? Quote Link to comment Share on other sites More sharing options...
316L Posted August 18, 2007 Report Share Posted August 18, 2007 @ cableguy how did you removed the tube? was the tube glued? details, please. i will do the same work with the same watch. Quote Link to comment Share on other sites More sharing options...
cableguy Posted August 18, 2007 Author Report Share Posted August 18, 2007 to remove the stock tube i used a 5/64 hex screw driver and just pushed in it so it would grab it and it twisted right out... i have heard of people saying its glued so you results may be different then mine...

cableguy Posted August 19, 2007 Author Report Share Posted August 19, 2007 no, use a 11/64" drill bit to counter sink i went too far down thou. "drill very gradually, until the cut approached the outer edge of the case...then stop. Also, make sure that your bit stays centered in the hole. Good luck."

jdavis Posted August 19, 2007 Report Share Posted August 19, 2007 The good side to this is that if you do open things up a bit too much, it is on the back side of the watch and it will be unseen while wearing it. Some of the cases that I have seen have the crown hole so close to the back edge of the case that it is impossible to countersink them without breaking it through the rear. There simply isn't enough material there to allow the countersink to stay within the case wall. Quote Link to comment Share on other sites More sharing options...
