In no particular order, and the proviso that these are all titanium as it is summer,
PAM036 (at the moment on BOB's platinum carbon strap, but while on holiday on a Veni Mignatta brown strap or the PAM rubber strap).
PAM192 (on ti/ss bracelet). Not 100% accurate, but I still like the blue hands and the dial, and as someone else has mentioned, the ss and titanium combination.
IWC GST Chrono in titanium - see Pugwash Great watch.
The MBW Silver Serti two tone sub could also make it - I'd taken it with me on holiday, as well as any number of PAMs.
