... 1) Suzanne makes unique pieces for the Patek museum (i.e. they are not sold to clients)
2) 5131s are made by a mother and son team
Hence, other artisans must therefore make dome clocks, other yearly enamel pieces, etc.
Given the overall number of enamel pieces produced a year, they must be made more than 3 people because I think Patek invests in training internal people to pick up the art and work with independent artisans (such as Anita Porchet who made the pieces, I think in 2012 or 2013 Basel, with the Arab horseman riding with an eagle on his arm)
