Hi, should i change crown and crystal when I leave my watch for service. Or does that effect the value in a negative way??? I am trying to learn the do’s and dont’s

 

Hello, I would not change anything unless strictly required.

 

Agree. I would definatelly replace both and keep the originals.

 

I would keep the original crown on the watch if not damaged. I would not feel totally happy wearing it knowing the original is in a drawer and not on the watch. Would only chamge crystal if the look of that one bothers you. Looks great to me as is!

 

Polish the crystal yourself. Keep the crown. Don't dunk it in water and enjoy.

 

Ok, and how do i polish the crystal?

 

I use progressively finer grits of sandpaper starting with 600 (400 for deep gouges) and work my way up to 2000 or 2500 then finish with a cotton cloth and simichrome polish but I've heard polywatch works too. Heck, the watch parts supplier at a watch show one time told me toothpaste (I forget his preferred brand) worked as a final polish. I asked if he had any polywatch as I've never used it and he was out and said try the toothpaste. I have resurrected some truly horrendous crystals. Even if not like new you will be amazed at the difference.

 

I'm all for polishing crystal - it's immensely satisfying and a lot cheaper than finding g a replacement.
However, before I started with sand paper on this one I'd find myself a couple of junk watches with acrylic crystals and try my hand at it first.
Yes, toothpaste will take light scratches out but there are much better products.

 

If you start at 800 or more it would be hard to do any damage. I mentioned simichrome and polywatch but toothpaste will get him started for fun but remember the polishes only work on cleaning up the fine scratches which is why you should work your way to the finest grit before you use it. By all means choose a junker and practice away. Always be careful not to sand bezels or other case parts. Although I really improved the lucite bezel on my Seamaster 300 166.024 doing exactly as I described.

 

Thanks!

Thanks!

 

Polishing the plexi by a watchmaker will cost you about EUR 20...

I use this on my Hesalite Speedy - works pretty well and is very simple to do. Bonus is that you don‘t scrape any material off the crystal

 

I would suggest you don't do any work to the watch yourself and leave it to a pro. The bezel insert is so fragile that you might damage it forever

 

+1

 

just in case you need yet more re-affirmation...yes you have an interesting watch.

 

Thanks

 

I did one soft polish with polywatch........

 

You are still going to have to use progressively finer pieces of sandpaper to remove the scratches. End up with 2500 then use your polywatch and you will be amazed. Still a great watch!!!

 

Thanks! And now completed with the right 7912 clasp
