I like manual movement and its finishing of the current model, but in my opinion toubrillon opening is disproportionally small comparing to case size. Plus the dial of the new one looks a bit austere to me, comparing to amazing guilloche of the original.
My bank still offers them, but in fewer branches. Safe deposit boxes are also getting smaller: I used to keep two perpetuals on Sempre winders inside the box, but right now the one I have barely fits two watch rolls. It is also important to keep it mind, that the bank is in general not liable for it
In over 30 years of watch collection only twice: a lady at the grocery store register thought that my UN Jungle repeater is a Disney watch and few years ago a gentleman recognized and commented on my UN Aqua perpetual. Other than that no one ever notices my watches.
If you know the year when the watch stopped, it is easy to estimate. If you don't, you either send it to manufacturer or risk pressing correctors thousand times to land on the correct year
I was lucky to be able to own or handle most of Venus based rattrapante chronographs with the exception of Paul Picot and Parmigiani: Franck Muller, Daniel Roth, Panerai, GP, UN. Daniel Roth had a best finishing by far, fairly close to the likes of Patek. The finishing of the rest is ok, but nothing
Perpetuel, Hebraika and Islamica used a clever module sitting on top (or rather on the bottom) of ETA movement, and as far as I remember the date change was very quick. The module was actually designed by Svend Andersen and wasn't very reliable.
Kurt Klaus and Ludwig Oechslin perpetuals using wheels as programming mechanism vs. traditional cam and lever design. That makes them very user friendly (everything is controlled via the crown, no pushers and correctors), but the downside is, that instantaneous date change is impossible.
Since all watch timing machines use sound to measure the amplitude and accuracy. Monolithic has amplitude of 6 degrees instead of usual 300 and due to ultra high frequency sound cannot be used. FC is using special laser based measuring machine. When I am wearing it it seems to keep an excellent time
