And now something old - a 1771 British (London), Edward Prior made for the Turkish (Ottoman) market: I think Prior must have received an order for a decent quantity of these from the Ottoman Empire as I have seen a number of these, but few as nice and complete. Having all four layers of the quad-case watch is reasonably equivalent to a modern watches box and papers, but this one stayed together for over 250 years. Regards, Art S.
I think Rob had a discussion of brands somewhere where these guys doing lists was discussed. Since I can't find it, I'll leave this here. Rob or mods, if you know where that thread is, feel free too move this post. Regards, Art S.
This is a fun one, especially at 9:50 where he discusses the F. P. Journe Havana and tries to explain the difference between a power reserve and an up/down or wind indicator which he claims this watch has (to me it looks like a power reserve). The purpose of a wind indicator (if set up correctly) is to let you know that you are running the watch in the 'sweet spot' of the mainspring (a mainspring's power is most linear away from either end, either fully wound or almost done). The wind indicator, if set up correctly, shows that the watch is running in this 24 hour 'sweet spot' of a longer spring (if set-up correctly, you can wind past zero and it will run well past 24). Although the hairspring should take care of the burden of isochronism, the up/down is supposed to ease the burden, thus improving timekeeping. I think Pol has (or had) a Havana. The funny thing is this feature was produced in volume in the old American railroad watches (chronometers) like this one: Except, this one has one more jeweled bearing than the Journe.

This one has a bit of a saccharin narration on top of otherwise pretty neat footage of George Daniels and Roger Smith:
