Patek Phillipe Nautilus Chronograph.
We used this watch in our Summer Campaign this year. It seems to be getting great press of late.
Designed by famed horologist Mr Gerlad Genta, the Nautilus was revolutionary when it was released in the mid 1970's for its size, at that time it had a massive 40.5 mm case.
Small by today's standards but still perfectly formed.
