Some excellent ideas posted in this thread. Obviously best in class depends on what class we're talking about! This is my solar collection:
G-Shocks are great for rough stuff
The Citizen eco-drive (bottom row, second left) is a great for casual when a G-Shock is a bit too chunky
The Citizen Skyhawk eco-drive (bottom row, second right) is great for world travel
The Oceanus is also a great travel watch and good for dressier occasions
Most worn is the Tissot t-touch titanium; two time zones, chronograph, countdown time, altimeter, barometer and compass.
The Citizen Skyhawk and the Tissot have travelled the equivalent of 10 and 6 times around the world respectively (and the Citizen has the wabi-sabi to prove it!) but are still going strong.
