Glass Customization



I´d like to replace a broken glass on a art deco rectangular vintage watch from possibly 40´s. The glass size is odd: Length=32.22 mm and Width=21.38mm. 

Existing acrylic glass is curved in both directions. 

Cousinsuk has for example following glass closest to desired size.

This one is curved in longitudinal direction only. The one curved in both ways available was relatively larger and may require cutting. 


Do I buff it away?I have a dremel with polish pads and polishing compound.

I now doubt the fitting with a glass one way curved only?

The closest I could find of double curved glasses on CousinsUK was:


Does it matter if it´s 0.22 mm shorter in length? Do I cut, buff or file it? If cutting, what tool needed?

I currently have a dremel with polishing pad and compound.

HI There,

My suggestion is that if you have not done this before is that you look to Ebay and see if you could get a selection of old Perspex crystals. These used to be available fairly cheaply. This way you could practise on a couple, but more importantly you could identify one closest to the shape (size is unimportant as this can be trimmed) of the original.

If you want to go down this path, feel free to use your Dremel to remove the excess, maybe a small diamond wheel is best, but use coarse/finer paper the closer you get. From my experience the Perspex is easy to scratch so use those sticky labels to cover both sides to prevent this.

This approach has worked for me and the end result can be pretty close to perfect.

Go well

    • Wide range of restorative attempts and I say good job, too many to master all though.  I buy more selectively focusing on the work you enjoy tirelessly.  Cute balance cock stand tell about the artistic person in you. All the best.

    • Hello guys. This is my last project – Seiko 6139-6010 aka Bruce Lee. Watch is from ‘69and it is based on the 6139A movement. Nice shot for the 50th Seiko anniversary of first automatic chronograph development. So please see the pictures below from all restoration proces. It took me 3-4 evenings. The watch came to me as non runner. Crystal was scratchy with many chips. Dial was dirty and dusty with signs of water damages. Hands lost their lume. Day calendar was loosen and didn’t work properly. Movement was complete but very dirty and dry – there weren’t any residues of old oil in the jewels. Somewhere were signs of water flood. I dissasembled movement and I gave it a bath in ultrasonic cleaner then i’ve assembled and oiled movement. Star disk od date wheel was repaird with small amouth of resin glue. Movement had tend to stop sometimes. Inspection showed that the tiny chip on the bottom pivot of the escape wheel. It was hard to see it. After replacment movement ran as a champ. I polished the hands cause there was rust and gave them new lume. Dial was cleaned. I didn’t touch the lume on the hours indexes. I was affraid to screw up it. I think now it is quite good despite the fact that the lume does not glow. Orginal crystal was polished but I decide that in the future I will replace it. Case and caseback got some polish works only with polishing paste, not too much cause I didn’t want to loose the sharpnes of orginal edges – as usual I did it. Bracelet was matted with abrasive wool. Everything was mix up and combined and there is the result. After measurments on timegrapher and adjustment it is a nice timekeeper. An amplitude satisfy me as well. Now I am enjoy to wear it. Please let me know what do you think of this restoration project and about my works on it. I appreciate your comment and your spend time. Cheers folks     VID_20191016_170551.mp4 VID_20191017_195141.mp4
