Progress and some photos

Some parts for jumping hour watch.
Steel dial layer was tempered to make it blue. This four layered dial has beautiful contrast between golden brass and blue steel.




I have to polish the head of steel made jumper lever because of reducing friction between itself and star wheel.


All parts of the dial and the jumping module are assembled. Now they are in test driving.
This watch making is nearing completion!

Dial making Pt.14 / Blue Steel Hands

I changed the design of the steel hands into more classical one. They may suit to the brass dial, I suppose. I cut out them from steel plate and trimmed its outline with various files.


They were rubbed with many sandpapers again and again. Just a little more...


After buffing...


Bluing is the next. On the thin copper plate which filled brass chips, they are heated until their surface color will change to deep blue. To heat them at the same time might cause uneven effect. Let's do it one by one.


It has become straw color.


Purple. Nearing the end. 


It seems they were done well.


Brass bush was fitted to the hour hand. And attached to the movement.
