Superb view on the three golden bridges tourbillon family, Nicolas! Truly a great read about a signature offering from one of my favorite brands.
What is highlighted by your post, and what I find very attractive about Girard-Perregaux in general, is the diverse range of watches they present with these special golden bridge tourbillons -- everything from the most traditional to the most innovative-looking. I am torn when deciding upon a favorite variant. I rather like the titanium Laureato with sapphire bridges, but also the fun Jackpot and the Vintage 45 cased watches. All are grand, in my eyes.
Thanks for this article on one of my favorite brands!
Cheers,
Daos
