How to remove scratches from plexidome

[Grapeshot]

I had a mishap with my cheap, but much loved, Quartz Omega Speedmaster. I managed to scratch the dome when doing some DIY.
I forgot I was wearing it.
In past years when in the Retail Jewellery sector I used Duraglit/Brasso wadding to remove fine scratches, but these are a little deeper.
I don't think that it is worth the cost of a new dome as I would have to get someone to fit it for me.
Anyone out there have any suggestions?

This is what I did, spread out a cloth or ideally a rough tea towel. Then put a smear of toothpaste along it. Baking soda/gritty tooth paste is best. Then rub the watch across that, you can get a good rate of speed up that way.

As you can see it's a mess. (Hope Alex doesn't see this - I bought it from him)

"POLYWATCH LENS POLISHING CREAM" on Amazon or your local hardware store

Yeah polywatch instead of toothpaste. They look deep though so you're gunna have to do it a good few times.
I've done it another way in the past, using the electric buffer I use on my bikes and cars, but I wouldn't recommend that to anyone!

I've ordered a tube of PolyWatch and a set of polishing tools for my Dremel.
If I keep the speed low, it should save a lot of effort.
I'll post the results as and when.

When you're using it take breaks, heat is the enemy when polishing anything, use plenty of paste to help with that.
And you'll need to cover the whole face of the crystal to avoid low spots. You don't want it looking like you've ploughed a furrow in there.

I wouldnt recommend doing this by your own, the scratches are too deep. And you have to remove the bezel for this task. Take it to your local watchmaker and have it fixed within minutes and without ruining your Crystal. I have polished lots of Crystals, and experienced, that replica crystals are often made of soft, cheap plexi which is burnded and melted in seconds, whereas gen. 50 years old Rolex crystals are very good and easy to polish.

I gave it a shot. I had to start off with 250 grit wet and dry to remove the worst of it. I worked up to 7000 grit and finished off with Polywatch. I think there is still margin for more polishing (The green deposits are from another abrasive I used).
The strange 'L' mark on the sub dial is only a lint thread.
For something that scratched so easily it was something of a task to remove. I know it's not perfect and the macro lense shows up a lot that you can't see with the naked eye.
What do you think?

Side by side.
