Thank you for this explanation. Patek Philippe has always taken the most number of production, testing, decoration and quality control steps in its watch movement and case production. This is one of the reasons it changed from submitting watches to the Geneva Seal for quality approval, to creating it’s own production quality criteria: the Patek Philippe Seal in 2009. The regular production steps and criteria of other watch brands did not meet with Patek’s own high level of production criteria. In terms of strict testing, accuracy and finishing steps in the productions of every part of a watch, the company has not changed.

Thank you so much for your question. Please can you elaborate a little more on what you mean by ‘two-fold construction’? Are you referring to a specific watch design such as the Nautilus?

I think it will be very interesting to see what kind of prices these pieces achieve at auction.
