…as soon as I find some time! As you assumed, I could compare the open dial round case (FB2 RS) with the octagonal FB1 case. And unlike I thought before, I liked the octagonal case much more and it fits my wrist better…
The FB1 with the first movement of Berthoud is already a classic, but this œuvre d‘or is even more special as the movement is fully made of gold bridges with a nice pyramid hand decoration and also the dial is made of solid gold, either way patinated by hand… That convinced me over the open dial…
More soon, thx for your interest…
