No idea what a 'tool' watch is, but I have to say that I've been mightily impressed with my Helm Vanuata for about a 1/4 of the budget.
It's running +2s/d, is beautifully made and finished and features a simple/cheap movement that's accurate but easily and cheaply serviced or even replaced.
It's ISO certified for WR and came on a bracelet and NATO, both of which are excellent quality.
I'm seriously considering buying a second Helm, so good is this watch.
