Altimeter setting creeps up on Suunto Vector

I set the altimeter at 50 feet when I received the watch 10 days ago and it was at 480 feet today. I haven't left the local area.

Also, the baro pressure reads 29.95 but the local sources say it's actually 30.08. Is this an acceptable variation?

    I have a Suunto vector, it was working properly until it started to show very high "negative readings" in the altimeter function. The rest is ok. What can I do?

It sounds like IC (integrated Circuit) in your watch is mulfunctioning, but can be something else. Can't say without inspection.None of the readings mentioned by you is acceptable.
As the watch is purely microelectronic, there is nothing you can do but to take it back to the retailer and ask for repair or replacement. If your watch is just 10 days old, this must be done under warranty and at no cost to you.
Don't forget to rate, please.

The reading of the altimeter will always change dramatically over time, even over a few hours. This is due to the fact that your altimeter uses barometric pressure to figure out altitude. Barometric pressure is continuously changing and so you need to frequently recalibrate you watch so that it can read accurately. I believe this is mentioned in the manual. It even recommends recalibrating altitude everytime you are at known height when on a day walk, so that you'll get the greatest accuracy. As for the barometric pressure not reading 100% accurate relative to the local forecast, it can depend completely on where the 'forecast' reading taken, unless it's at exactly the same altitude and within say a 5 mile radius of you location, then there is plenty of room for deviation. Having said, that barometric pressure you gave must be in imperial measurement and so I'm not sure how great a difference there is between 29.95 and 30.08. This can depend on what kind of area you're using it in- temperate climates and / or mountainous and coastal areas are much more subject to barometric pressure changes compared to say flat, dry, continental interior areas.

How does the altimeter function work? we can't find it on the enclosed instructions

Altimeters on watches are usually based on barometric pressure, since the pressure changes all the time you generally need to adjust the altimeter to a known altitude. You can look on USGS website to find the altitude of your area, or simply type in "altitude of city, state" in a search engine.
I hope I understood your question; if not, please reply.

Tissot T-Touch Baro way too high

Try to recalibrate the Baro/Altimeter as below:

Certain functions need to be calibrated. The altimeter and the Meteo are tied together. When a customer gets the watch, they should calibrate to either the Meteo or Altimeter. The easiest way to find out the altitude of the nearest airport (you can usually get this on line) and then go to the airport and adjust the watch. This will also calibrate the Meteo.

To calibrate the Altimeter:

1. Activate Crystal
2. Press Altimeter
3. Press and hold top + button until the watch beeps and display flashes.
4. Use + and – buttons to adjust altitude
5. Press center of dial to lock in.

Tissot T-Touch : Faulty reading on Thermo, no reading on Altimeter and meteo not working either

If it's under warranty by all means pursue a fix. You might have to send it to a warranty center instead of working with your local dealer.

"Water proof" and "water resistant" are very different. About 20 years ago all watch companies stopped promising waterproof and started using the term water resistant. It gives them wiggle room in the guarantee, unfortunately. I believe T-Touch is supposed to be water resistant to only a few meters.

1. How do you know the meteo is wrong? Are you comparing against a known good measurement device?

2. The altimeter requires adjustment every few days or whenever there's a weather change. Select the altimeter, hold the upper or lower button until you have the correct altimeter reading for where you are and it will hold for a few days.

For example, I know my home is at 100m elevation (I checked on a topo map) so I reset it to 100m when I leave the house in the morning. It varies (in my case) by over 100m in either direction, depending on the weather.
