I do not want to buster opened door but I would say that my favourite case is the last one : that is to say the Trio.
The work for this is totally different from the previous ones : the table is brushed while the side are mirror polished with diamond cut angle. The final result is so amazing that I wonder why I have waited so long before launching this watch in production.
Nevertheless, I must frankly recognize that the relationship between a watchmaker and his watch cases is like a love affair : sometimes it's up , sometimes it is down. As an example, I am strugling with a serie of Classic watch cases that are specially difficult to finish : I do not know why perfectly polishing them is that time so difficult with unbelievable micro rays that appear while I polish. It is the metal structure, is it the polishing past, the temperature, the position of the planets, or simply myself who is much more demanding than usually ? I do not know and I am about to give up.
The only thing I am sure of is that I want these watch cases to be excellent prior to leaving the manufacture and tonight I hate Classic watch cases.
