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.

      Kalle Slaap said he is visiting London this week in order to see the exhibition. I was keeping an eye open, hoping to meet him.

      Notifications

      By JohnR725 · Posted

      if you're trying to keep track of conversations scattered all over the message board emails are an absolute must.   looking at the bell icon on the top of the page versus the emails today it looks like I got the correct amount of emails. So making some minor change based on the one of the images up above I started getting notifications again. But at times I still have a suspicion that something isn't quite right. I have some feeling that the message board may delay sending emails until something so seems to be a long delay between when you get your emails just a weird feeling things aren't quite right oh  and then even though I do seem to be getting emails I no longer get notifications of personal messages I don't find that out until I arrived at the message board where I'm pretty sure I used to get notifications of those two. So something is definitely changed on the message board. then for everyone not getting emails you do want to check your spam folder. I have found that sometimes were open up an email the system I use warns me that it thinks the email is evil and bad and I have no idea why he thinks some of the emails are and some are not. But this is actually the program I use not the email system which also has a mind of its own as to what it considers spam so you should always check your spam folder.
