Noel Y.wrote a review of Casio PRW2500R-1 Triple Sensor Altimeter Watch on April 21, 2013
Really like it. More durable than the Core, with more features, for less coin. If you're into bona fide mountaineering the Core is probably a better choice because of the barometer/altimeter lock, the Casios don't offer that. For general use and anything around water this little gem is hard to beat. Tons of accurate info in a nice package. The band is noticeably more comfortable than other Casio resin bands too. Happy hunting.
