Well, it is a knowhow that Patek has chosen to develop again since quite a number of years
As in other fields of old techniques, especially regarding what is needed to service old pieces.
The 5131J was I think the first of a more limited production but regular piece in the catalog. I don't think that enamel work was successful back then but Patek took this decision regarding the historical value of such craftmanship. I don't know for other unique pieces that are part of the Rare Handcrafts family as they are usually not presented in the catalogs.
Today, several high-end brands provide enamel work and I think this is for good.
Nevertheless, even if we talk more about them, they remain very rare in terms of output, whether compared ot the overall production or considering the market size.
Now, how will it evolve in the future? I can't really say but my opinion is that there won't be that much because it takes time (to craft with a lot of waste and many years to train one enameller), there are not that many enamellers yet and I would say they wished to keep numbers low to preserve the "image" of such work.
Best, Mark
