the Suunto Clipper compass clips to the watchband

The biggest single difference from the 1500 is the absence of the compass -- almost certainly a worthwhile tradeoff for overall size.Here's a comparison shot with a basic Timex Ironman men's watch. As you can see, the pressure sensor makes the pathfinder a bit wider, but not much.Certainly at 45mm, this is a watch with presence and quite well sized for a man or woman. On my wife's smaller wrists, it was a bit large but quite comfortable. On my 7.5" wrist it looks perfectly normal. The pressure sensor is on the left of the watch between the two buttons and is protected by a plastic shell that looks quite well designed. As is the case with other Pathfinders, the strap is custom-fitted to the watch and can't be exchanged for, say, a nylon NATO strap. We quite like the combination of solar power and multiple sensors for an outdoors watch -- if you're a long way out, a watch battery is one less thing to worry about.The 11.5mm height keeps it nice and low-profile.You also lose the tidal display and moonphase, the utility of which depends on your lifestyle. Werewolves and surfer girls probably want those; hikers and outdoorsy types perhaps less so.Construction is a mix of rubber (most of the case and strap) and metal (reinforcing on the case and strap, plus caseback and front of watch) that gives it a light weight and very sporty look. The buttons (2 on the left, 3 on the right) are grooved and recessed, with small ledges to prevent accidental presses.
