Nice watch I also considered the Riseman but (sadly) its pricey on ebay and amazon bur I can find this for around $75 on amazon or ebay

For the thermometer and barometer thermometer need to be calibrated bur the altimeter isn't as accurate as id like it to be but overall a good watch. now i wonder how much id like the riseman in comparison to my GDF100
