Though it may seem that using rare and even unusual artistic crafts is a major trend running through high horology at the moment, it is important to remember how very difficult both the execution of and inspiration for these crafts can be. Guilloché, enamel, engraving, and even gem-setting are skills that almost died out in the pre-mechanical renaissance watch industry along with the art of mechanical watchmaking itself. Therefore, there are truly very few artists today able to perform them.
