same here, love the 3330 & 3337. Not to mention this is a direct descendant of AL Brequet pocket watch 3833, sold to M. Thomas Hawley on May 12, 1823. So much history here.
My father has one too. Its 5 types of guilloche by my count including the straight line pattern bordering the chapter rings. I think its one of the best dials in all of Breguet's line up showing having a considerable variety of exceptionally nice guilloche patterns while still being very well balanced and proportioned. And I really appreciate the fact the layout is one that was favoured by Abraham Louis Breguet for several watches back in the day.
