That’s the one I have used.The D6x50L one?
I’m hoping to compile all this information into a big post. I’m gonna grab both an 0.30 and 0.35 tap and see how each of them fares. I measured the shoulder of the case tube, it’s 3.78mm so I would think a 4mm counterbore would do. The OG 5513 tutorial by @Megahz1 used a 6mm 90deg counterbore I believe, and just titrated to effect.Right chaps, now we have the tap (or back and forth method) sorted for our 7030 tubes... what countersink tool are we using?
Any recommendations? @Karbon74 - Do you have a link, Pika buddy?
This guy and this photo are the only two sources that conflict with the prevailing M3x0.35 wisdom. I’m gonna try to tap both into a block of steel and give it a try. I can tell you now that I had far more trouble getting a gen 7030 tube into the Old Crowns case than every other Rolex servicing video I’ve seen. I’m gonna order both the 0.30 and 0.35 taps that @HulkyGalore found on eBay (I also found this on Amazon and see how an Esslinger tube compares. Will post my results once everything arrives.I said:
Genuine Rlx 6.0mm and 7.0mm case tubes use the same tap size...3.0mm X .35mm (3.0mm diameter with .35mm thread pitch).
Later sapphire DJ etc. have 6.0mm crowns with 5.3mm case tubes and use a different case tube tap...2.0mm X .25mm (2.0mm diameter with .25mm thread pitch).
I made a typo mistake on the 5.3mm case tube tap size. It should have been be 2.5mm X .25mm (2.5mm diameter with .25mm thread pitch).
I looked at my case tube taps for older 6.0 and 7.0 tubes and they all are 3.0 X .35mm and they came from different USA supply houses.
I looked at the Esslinger website today and they are offering 3.0mm X .35mm taps for Rlx 6.0 case tubes and I have also seen 3.0mm X .30mm taps mentioned on forums.
I have been getting by with the 3.0mm X .35mm taps but have read a LOT of posts concerning case tube thread sizes on different forums.
So...I am officially backing out on case tube sizes. Looking back, I should have kept out of it...typos and all.
No, you can use a 703 Tube without retapping. Also you can retap the existing threads. But not really necessary.In order to re-tap, its my understanding the M3 hole will need to be filled in with weld and then re-drilled and tapped, is this correct?
Way easier to buy 703 gen Spec Tubes without the small edge on the back. Look here. No need to countersink the tube hole.Tube threaded M3x0.35 and glue/thread lock applied.
An Athaya 702 tube should go straight in without further work.
GEN/GEN-spec 7030 tube would need countersinking and installing carefully if threads are 0.30. All answered in this thread.
Think there is only a single batch, so lug holes will need drilling out to 1.3mm for fat spring bars.
Any link please?Way easier to buy 703 gen Spec Tubes without the small edge on the back. Look here. No need to countersink the tube hole.

Do we think/know if they are GEN-spec 0.30 or REP-spec 0.35?I just found this on AliExpress: 5,68€ | Case Screw Crown Tube With Gasket O-Ring For RLX Day Tona, GMT SUB Submariner Watch Replacement 3135 Movement Watch Case Tube
I use exactly this tubes for my cases. Perfect fit without any work + gen 703-704 crowns fits on this tube.Do we think/know if they are GEN-spec 0.30 or REP-spec 0.35?
Have you used one in your case, DrV?
