Looks great, Vilts
Those celtic designs can certainly tie you up in knots
Is that leaf on the side of the watch marijuana or some sort of Estonian acanthus leaf?
Very nice design. It adds character and style to that watch! Very well done!
I clicked on your facebook page. Engraving, coin presses, audio, and the rust bluing box. Very neat things you are doing there!
As for the cracked coin die, that's disappointing! Good tempering is a must! Perhaps O1 would be a better steel, or even S7 or H13?

When you are heat treating the die, are you taking into count the size of metal you are heating? The larger the amount of metal, the more long you need to keep the piece at temperature in order to make sure the entire piece is heated throughout.

I think so, I hope so
The piece itself is 35mm or 1 3/8" diameter. First I heat it up to 700C/1300F, keep it 10 minutes. Then heat it up to 850C/1560F and keep it there for 50 min, quench to rapeseed oil. Then 2 x 2h temper at 270C/520F.
