It is a very distinquished hammer set. I own the same tool set and feel myself very special even if I am not using it by an expensive watch repairing process. The weak point is,the polycarbonate head should only be used on plastics and wood material. It is very brittle, specially the edges .The edge of my hammer's polyacrylate head is already broken , probably the impact I applied was a bit to much or I missed the target.
Best wishes and enjoy your hammer set in healthy days
