Hello Watch and Clockmakers,

i recently serviced a CAL 400 movement and I have one last problem, at least i hope so. The original "crystal" needed replacing but the new one is not high enough and probably does not have the same shape, to say the least it does not have the same wall height around the edge so what happens now that the crystal is pushing the end of my second hand to the minute hand. Cousins have "Domed Extra High, Sternkreuz HH" is this what I supposed to go for, or shall i try another high domed crystal from a different manufacturer? 

Take care and my best regards,

Lui

What is the brand of the crystal. That looks like a low dome. I normally use GS crystals and the left one looks like a dive tite or one of “tite” models. Was there a tension ring. I never really order from cousins because shipping takes forever to USA, so not sure what they sell.

Sorry i was not clear, probably even misleading, what i have on the picture are Acrylic Round Domed Watch "Glasses", and i have a set of DPA "glasses" from CousinsUK. What I am planning to do is to buy one "Domed High without Step, Sternkreuz Hw" and a "Domed Extra High, Sternkreuz HH" and compare them. What are GS crystals?

GS is a brand of crystal mainly sold in the US. But they have a really nice variety as well replacement crystals for many watches brands including swiss. You can try some type of diver crystal just remove the tension ring and glue it like you would nornally. Iam not familiar with the crystals you have

I compared 4 292 crystals together. An original crystal coming from a case hiding a CAL400 movement from Services, a DPA, a sternkreuz HW and a sternkreuz HH, you can see them in this order on the pictures from the left to the right. I used a cheap but relatively accurate digital caliper to measure the height and diameter of them.

                                            Diameter                               Height

Original Services                 29.1 mm                                4.4 mm

DPA                                     29.11 mm                              3.75 mm

sternkreuz HW                    29.3 mm                                4.0 mm

sternkreuz HH                     29.25 mm                              4.7 mm

The sternkreuz HW made the trick, the second hand is free to rotate now, took me a while - as there are so many other things i have to/want to take care of - , but it was worth it as I again learnt a bit.

      Movement inserted from crytal side

      Before putting it back in the case I would fit the hands and use a pin vice on the stem to make sure the hands were in line.

      Put the movement in a movement holder and it will be supported as you push down on the setting lever post to release the winding stem. Make sure the post is over the shoulder of the movement holder so what you are pressing down on is supported. As a general rule, hold the movement and not the movement holder. Replace the hands when the movement isn't in the case and support the centre jewel (if it has one) on a hard surface or staking block when replacing the hands to stop the jewel accidentally moving or even coming out. A dedicated movement holder with a central jewel support is even better, but pricey

      It might help us if we knew which watch like model number.

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.
