New pro/con: Removing band links requires knowledge due to unusual pin-and-sleeve design (also used by Seiko on some watches). Band setup by an inept technician can result in separation.
New pro/con: Not a diving watch. (This really isn't a con, but some people gripe about certain Pathfinders not being diving watches).
New pro/con: Case design is tough, and the hardened glass crystal is recessed scratch-resistant.
New pro/con: Solar charging means regular battery replacements are not needed. In other watches, the same internal rechargeable battery has been good for 8-10 years of service, and it is replaceable.
New pro/con: The compass is reasonably accurate.
New pro/con: The barometric pressure graph is wonderful-- like having a weather station on your wrist!
New pro/con: Illumination is brief at ~1second, and is fixed.
New pro/con: The thermometer is mainly intended to compensate the silicon barometric pressure sensor, so it shows wrist temperature unless you leave the watch off for 20 minutes or so.
New pro/con: Like all barometric pressure-based altimeters, Casio's altitude readings can change based on weather, etc. Per the manual, calibrate to a known waypoint if you want accuracy (it's quick).
New pro/con: Nightly atomic time sync plus native quartz accuracy makes for dependability and convenience (Daylight Savings Time is handled automatically)
