To celebrate the 5th anniversary of the Art in Time gallery in Monaco,
Ferdinand Berthoud releases a limited series of 5 pieces of its cylindrical hairspring model (FB 3 SPC for "spiral cylindrique") in sandblasted titanium.
Not my personal cup of tea, but some of you might like it.
Best to all of you.
