For those who find the topic of interest, I purchased a Suunto Vector last week for about $200. The barometer is a four-day recording type and it has a reasonably accurate compass that will work five feet off my aft steel deck, but goes squirrelly any closer. It has a dim "night light" as well, which won't pooch my night vision and it's good to 30 metres of depth, which argues for its water resistance to spray, at leasts. It also has various alarms and timers and an altimeter which I am less likely to use. It seems it's primarily a skier or mountain climber's watch, but it's got the features I want.
When set for the local height above sea level (about 80 metres at the lake and 90 metres at my house) it is within 2 mb of actual pressure as per the local weather service stations. That's good enough for me...I want the trends and speed of rise and fall more than the raw number.
At $200, I can afford to give it a shot. This is the model. I went for the reverse LCD face.
