I don't own any, but that's because I only own Carreras. If I did have a horizontal, rather than strictly vertical, Heuer collection, I think I'd definitely have room for a Silverstone.

What I've always liked is the lengths they went to with the different dials. Note, they are not just 3 different colours (on the Cal 12 models), but 3 different finishes too. The starburst brushed fumé, the glossy red, the powder finish blue. It makes it hard to pick a favourite and I can completely see why people are compelled to catch 'em all, Pokémon-style!
