I bought this about a year and a half ago, and it has not been off my wrist since. I bought it to replace an earlier PRG-40 pro trek, and the additional expense for the titanium band is worth it for the feel alone when compared to the resin strap on the previous model.
When wearing, it feels much more solid than the PRG-40, and becuase it's solar, much thinner too. You also don't need to replace the batteries (>£60 in the PRG-40!), and the radio setting of the time overnight works faultlessly too. I've had occasion to try that feature in the US, China, Africa & Europe, and so long as you set the region, there's no problem.
The only thing it misses compared to the the PRG-40 is the minimum altitude record, hardly a big deal. After 16 months of sailing, cycling and everyday wear, it's still unscathed.
You buy a watch like this because you want the features. If you're tempted, I'd say go-on, as you won't be disappointed.
