The smart option

Tag Heuer’s “Connected Modular 45” is smarter than most. The standard Android-based electronic unit – offering Bluetooth, wi-fi, GPS and NFC chip (for payments) – can be swapped for a mechanical movement. The lugs, case, buckle and strap are also interchangeable, with 56 permutations making it possibly the most customisable watch you can buy. Manufactured from titanium, with additional finishes in rose gold and ceramic, it spans 45 millimetres, is water resistant to 50 metres and carries “Swiss made” certification. Priced from $2100.
