I'm a pretty active racer primarily match racing and some fleet racing thrown in as well...have been using this watch (my second in the same model) since 1998-99.
Has a triple sensor (digi-compass, barometer & thermometer). Fairly accurate at that.
If you buy the correct model SPF-40 (seapathfinder, not the same as sunblock), you also get a neat tide graph and moon age etc.
From a racing point of view it has a Yacht Timer (gives you beeps at every stage of a standard pre-start countdown). It also comes with a titanium bracelet as against the resin one.
The first pic is with the watch in compass mode, the second shows the baro and temp reading (the curve on top shows if the baro is falling, rising or stable). The tide graph shows in all modes in a wave form and currently is indicating high water.
Won't appeal to those of you who'd rather go for the analogue look though.
If you can find it, the price should be around 100 GBP (
