I bought this watch as I am a surfer and looking for one I can wear in and out of the water. This watch is perfect for that! Took some big beatings on wipeouts in Fuerteventura and it just shrugged them off, absolutely no water leakage and no scratches from all that sand/knocks.The tide graph is quite neat although a bit of faff to sort out - it calcualtes from the lunitidal interval which you need to find on the net, and you can not set it up for more than one beach like some other watches I have seen. The moon graph is a very nice touch. All in all a very practical watch for active people but will not disgrace you in meetings at work!
