PRICE : -under consideration-
Generally jumping-hour model has a disk-dial. But I wanted the appearance unlike a general one.
When the minute hand rotated in one hour, the hour hand jump to next hour marker quickly.
The jumping action is caused by linkage of three star-wheels and one push wheel. They are controlled by spring levers. I had a hard time to decide the strength of the spring.
I chose ETA2801 hand-winding as a base movement, because I wanted to build this model as thinly as possible. The jumping-hour module needs a certain thickness. When automatic mov is adopted, the stainless case will thicken more than 1.xxmm. The difference is huge, I suppose.
(The movement in this photo is temporary. Its decoration is going to be changed...)
Brass inner holder has 'Pelrage'.
Polished steel hands, wheels, jumpers were made by my hand. Dial is composed from sand-blast finished brass base and blue steel index plate.
My wrist is thin. But wearing feel is good!
