The chosen pieces are the acme of horology (i.e. 5016, 5959) both either in handicraft and ability to squuez in so many complications in a small space (i.e., 5016 is just 37 mm) and 5959 (also 36 mm).
That's is the cream of the cream, agree? And they are produced in such small numbers that they demand a high price.
Why are we here, may we ask? To appreciate the horology and be amazed by the acme pieces.
The thread asked us to choose the top 2 pieces...naturally, being the top 2, they are most sought after and hence happen to be most expensive.
What are your choices BTW?
