Over the last 15 years I have repainted over 5000 clock dials. I have photos of each one. So, if you have a dial that is flaking really bad send it over and I will put it back the way it should be.
Zinc Dials – $100-150 depending on complexity, not size…
Silver Dials – $200-$300 depending on shape.
Tallcase dials cost roughly $350 to restore / rebuild.
Porcelain – These are expensive. To remove cracks and fill holes is around $600 but I have to have several people look at it to determine feasibility and cost.
