Hi all. I have almost completed restoration of a charismatic watch I bought off eBay some years ago. At the time my skills were poor and I actually did more harm than good to the movement. However I recently bought a box of junk watches at an auction for £5-50 and was happy to find a newmark mk11 movement with reasonable condition hairspring which became a donor for the original one I managed to mangle and break.

 

Anyway, the original crystal has taken on a yellow hue and is frosted with minute surface cracks. Polywatch just reacts with the older crystal material and goes sticky. Making reference to the photos below, would I be correct in selecting a sternkreuz micromcave ‘M’ style? I’ve plenty of practice with the dome / high dome type crystals but never had to replace one of this profile before. Thanks in advance, Deggsie 4c64656d02775073b0bba55bdb67ef65.jpg064f1e3c4c18294f2d4b21c1f18aac3e.jpgf5c352fb9106709fe43a5eafdf1aecc9.jpg

CousinsUK has what you need. I forgot what the name of the crystal you need is called. I believe it should be an acrylic crystal high dome... or maybe it was low dome ?

Hi Chopin. This definitely isn’t high or low dome, although I might try a low dome as I’ve at least got the tooling to install it. Just conscious that the watch is already ‘chunky thick’ and domed crystal will add to height

    • Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.
    • Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.
    • isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
    • That Island looks pretty good on the pics I found. Must be nice to live there. Welcome! Are there many watchmakers over there?
    • I believe so. I thought about it the last time.
