It‘s really difficult to decide on a favorite technique. It‘s easier to decide on my least favorite of these techniques and that‘s the miniature painting. Cloisonne enamel, wood marquetry and engraving/enamel are all interesting and if I‘d have to decide between those, I‘d decide based on the motifs available for each of them and not based on the techniques themselves. 90% or even more of the motifs chosen by Patek for the rare handcraft watches don‘t match my personal taste.
