This is one from next door I did so I thought i'd post here too as it worked out OK.

So after getting the thing apart I had a go at giving it forced patina using liver of sulfur ($8 for a bottle off eBay)

I bought it with a view to getting some cool patina so here's what I did for anyone interested.

Striped off the bronze bits and washed in warm soapy water and dried.

Placed parts in a dip basket or sieve and made up 2 solutions. 1) Five blobs of the LOS gel and 1.5 cups of warm tap water. 2) Two tablespoons of baking soda and 1.5 cups of water to rinse and stabilize the chemical reaction.

Dipped into the LOS solution for 60 seconds on the watch. Make sure the crown is screwed down!!

Then out and into the baking soda solution for 5 minutes to make it stop reacting. I then rinsed under the tap and dried in with a cloth.

The buckle looked awesome but the case went really dark almost anodized and too uniform. Case and buckle is obviously different material ratio.

The case didn't look how I wanted so I broke out the Cape Cod and went to work for a minute or so, you can be quite rough it's not an exact science I discovered.

Finished watch. Looks better than the original finish to me anyway. I'd like some crust and green colouration in there but i'll have to read up how to get that. I'm happy how it turned out though.

That is pretty dramatic. How do people discover these things? Was I not paying sufficient attention in chemstry class?

All I can remember from chemistry class was fingering Zoe Scott in the supply room. I found this info on the interwebs :drinks_cheers:

Now added some green crust by misting it with salt solution. Looks cool but is flaky and delicate. If anyone knows how to stabilize or seal it please let me know!
