For Special Occassions .....
3) must have a Tourbillion - Blancpain fifty Fathoms Tourbillion yellow gold - I like the combination of divers watch with a tourbillion, which make this unusual. The only yellow gold watch in my selection. as it's a tourbillion I think the blingier yellow gold suits it.

4) must have a Patek - Patek Phillipe 40th Anniversary flyback chrono in white gold. I like the Nautilus, and the 40th Anniversary is extra special.
