Hi, all

I was about to finish Omega 601 case 135.04 after spending some time polishing the crystal and then breaking it while refitting it 🤬 I've been checking on Cousins for a replacement and I will go with a 36.1mm outer. This is where I'm either dumb or just can't see the information in the Sternkreuz G22 document that Cousins points you to for relevant info. I know I want an armored crystal with the reference number ATC316 but there are a couple of options for either a standard or wide ring and this is what I wanted to check in the caterlogue against the broken one. From what I can see from the G22 document is a page showing the packaging for ATC crystals but no other information. Am I just being dumb or should I have gone to sepcsavers? 🤭

So is it a 135.041 or 135.042 case?

I presume the 36.1mm is a typo and should be 31.6mm as the ATC316?

Is it a gold or silver case?

Oh dear I should have gone to specsavers 😂 The case is 135.041 silver and the old crystal measured 31.6mm outer. I saw on eBay somebody selling a crystal for this case and they also had it down as being 31.6mm so that confirmed my own measurement. I won't be buying that one though as it was a lot more expensive than a cousin's offering, if not genuine.

So Cousins do the PX5005G which is a Gold Ring which also confirms the size is correct.

I can't see anything showing a Standard or Wide Fitting?

Where did you get this info?

Edit

ATC = 1.25mm & ATCB = 2.25mm

I will just check the height on the broken one first

If you could post the width of the tension ring this may be of benefit to someone in the future.

The outer diameter is 30.5mm, the inner 29.0mm, and the thickness 0.9mm  

So what's the thickness from the outside of the crystal to the inside of the ring, would this be 2.6mm, 31.6mm Crystal and 29.0mm Internal.

If that's the case then the ACTB may not be suitable as a replacement at 2.25mm.

Edit

I've left the above but just realised that the 2.6mm is divided by 2 so the ACT would probably work at 1.25mm.

    • Righty ho, I re-serviced the chrono module and got a reasonable result with minimal loss of amplitude when not running the chrono and about 30 degrees loss when running. Great. The problem is now that the chrono (and movement) stops running after about a minute or so, a tap on the watch starts it running again. No issues with the movement running when the chrono is stopped. Going to service it yet again, obviously some residual issues with friction in the chrono module (Very frustrating - I wish there was some way of testing it as I go!) I also seem to have a problem with the cannon pinion where the movement is running continuously (with the chrono stopped) but it's losing significant time / stopping. This is one of those two piece ETA style with a driving wheel pressed over the cannon pinion, obviously arranged for driving the chrono module. I had no issues with this prior to service and just added a small amount of grease between the driving wheel and the centre cannon pinion as the technical guide required. What's the best way of tightening these up? I would like to replace it but I guess this is going to be hard to find as it is dedicated to the DD chrono movement. 
    • He uses the micrometer cap, but he leaves the spring out (you can see that in the video). If you leave the spring in, the spindle will move up as well (as shown by @Knebo).
    • Seems like he doesn't have the micrometer cap  attached to the spindle so he can only push down but cannot pull up? If the cap screws into the spindle I guess you don't need the spring? I only have a "normal" Seitz so I really have no idea. 
    • Do you have a part number for the bearing shim lock tool?
    • Yes in my opinion the 3/4HP is plenty but it’s your decision & yes it does come with speed control but foot operation so my reason for changing to potentiometer was because my leg shakes so it was like me revving the lathe & anyway I prefer to set the speed. I & a few others that I recommended the motor to run a Pultra 10mm lathe so if you have a 6 or 8mm B & L then it will be plenty, if you have seen any of my videos you will have seen that when using a graver I run quite slow without any problems.
