It takes no more then 15-20 minutes... 30 if you have two left hands, like me.

Nice job.

I used to use liquid brasso on a rough cloth and rub the Perspex glass vigorously on it. The heat generated would help polish the glass nicely.

Brasso does a good job on glass crystals also, won't remove the scratches but it polishes them and they don't stand out so much.

hi matabog,

beautiful work!

i was wondering if you would mind posting a more detailed step by step of how you did that. (please)

i am presently working on a beautiful Hampden whose crystal needs work.

i either fix the crystal or order a new glass one from WW.

he is very reasonable but i would rather fix what i have.

I love this site by the way

thanks

Todd.

The nail file that I used is a cheap chinese 7-faces nail file. I used only the faces 3 and 4 which I believe are the equivalent of some 800-1000 and 1500-2000 grit paper. The nail file has a soft rubber material immediately under the grit-paper and so it somehow better contacts the plastic watch-glass. After covering all the deep scratches with the lower grit-paper I turned to the higher grit one. You can do that in two or three steps, depending on your hurry. My advice: clean up after each step because if you get a "large piece" of plastic from a previous step in the current higher-grit paper you will induce several other scratches.

 

In the end put some cotton material on a soft surface (I use that yellow sponge-like material) and over it put a drop of polywatch. After about 5 minutes it will look spotless.

 

The above "method" is what works for me It is my personal opinion - others may differ.

I do appreciate that some people will spend time to refurb an item to keep the original but on a personal basis I would always know that the crystal wasn't right and it would annoy me.

 

I'm sure that it would cost less to just get a new crystal and replace the old one. Job done and a sparkling new looking watch.

I think it is debatable.

 

The topic title is Cheap and Unprofessional Plastic Polish. I am talking about a 30$ watch for myself, not for a customer - I am not a watch repairer, just a hobbyist.

 

I didn't polish it to keep the original but because it was cheaper and easier.

 

Thank you,

Bogdan

Hi Bogdan, I'm not saying you are wrong in any way and I do appreciate what you say so please don't misunderstand me.

 

Perhaps I am lucky and watch crystals are very easy to obtain here, also I am retired with a decent pension so if I want to keep a watch for my own use then I want it to be perfect without, what I consider to be unnecessary work, and I am lucky enough to be able to pay for most parts without any difficulty.

 

I think you have done a great job and wish you all the best.

 

Keep up the good work.

 

Mike

I apologise if i seemed defensive - english is not my first language, obviously.

 

For me, all the fun is in the watch movement. I am not too interested in the rest. The fact that it is a new crystal or a polished one makes no difference to me.

My tuppence worth.

I prefer to sand down and polish acrylic crystal if they are original to the watch. On numerous times I have ordered replacement crystals for vintage watches and found the profile to be incorrect. I guarantee an acrylic crystal sanded and polished properly will have as good a finish as a new one. Done correctly it takes quite a bit of time, you won't do it properly in five minutes.

Agree, specially knowing that those factory made have been done in the same way by machines...and what about the satisfaction of having the authentic item and restored by yourself!! It is a pleasure that can not be described...

 

Also, it is a hobby anyway!

 

Two more pennies! :)

 

Cheers,

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
