Sun Burst

Decorative touch for circular areas (circular graining): Changes to the swinging motions of the clock angle of incidence of the light travels the reflected light from the ground surface in a circle.


In the lexicon of watchmaking from 1902 states: The sunburst is made on a swivel chair with hollow spindle. The hollow spindle is given to using a slip cover and the place of the bearing engaging a half circle is mounted so that it is easy to move both in one direction and in the longitudinal direction. We now set between the tips of the engagement circle the wheel, which is to get the cut and let it run with the grinding bell in the hollow spindle, so this creates the so-called sunburst. In order to obtain the first grinding opposite direction is the engagement of one circle with its side screw slightly further from the center of the bell grinding away and rotates the wheel in the opposite direction.The grinding bell is coated with fine emery angeriebenem in oil or oil stone. A beautiful sparkling cut is obtained if one rouge mixed with oil stone dust used.

When sunburst there are slight differences, depending on how you do it and with what intensity. It can grind the teeth of the wheels again and also connect a high gloss polish.Of course, everything by hand. Cost: + 100, - Euro per set.


Here are some examples.

On request, we can also bluing the winding wheels. The wheels are heated by the flame and the stainless steel turns blue then. This work is very complicated and requires utmost concentration, because the blue color can be achieved only in a certain temperature level. This very intenstive blue color is to excel in their beauty barely. In contrast to the blue paint, blue loses stainless steel, even under strong light effects, not its color. Costs 150, - Euro per set.
