I purchased this watch and a Casio twin sensor (compass/temp) on the same day to compare them.  This Timex is very lightweight and has a nice water resist leather band.  It dosen't feel as tough as the Casio does, but that dosen't mean one will outlast the other.

Having a temp sensor on a watch doesn't give you much of a tool, as it is always will be influenced by the wearer's body heat.  The Casio would give accurate compass readings if I was not wearing/touching it.  When I was wearing it, I couldn't get anything close to a correct compass reading.  This was a deal breaker and I returned this watch.

The Timex has a better backlight with the Timex Indiglo feature.  It also always gave me accurate compass readings and there is a tiny bubble level at the 12 o'clock position to help you have the watch level for an accurate heading reading.  The Timex cost $5 less than the Casio, and I will be keeping it.
