The trip may well be worth it
The TimeWalker Chronograph UTC is definitely a good choice - and you will be properly attired for the Goodwood Festival of Speed, too 
As for the 1858 Tachymeter in Bronze, it is a most appealing choice and the highest grade Bronze watch out there just now. The addition of a bronze coloured titanium on the case back (the non-transparent section) is also a lovely design touch, making sure no allergies will ensue. Probably worth having a conversation with your bank manager over this one...
