Tissot T-Touch Baro way too high

If you take a jeweler's lupe near where the arrow is you will see the word "reset" in the plastic.
There is a deep hole in the plastic with contacts below. That is the reset, and that is why you must use very sharp pointed tweezers to make contact with the back of the battery.

I think if you do not have sharp tweezers, you can probably put a sewing pin down the hole, and then connect with a small screwdriver to the back of the battery

These babies are notorious for going down the tubes with a battery change. I bet if you get it back it won't work with a new battery. Twice I have replaced batteries and the watch didn't work when I finished. One of them was my own watch, I think $450 is about half the price of a new watch and that is sad. Cool watch just not very long life

here is manual

Per the manual: http://support.tissot.ch/usersmanual/140-en.pdf
When your battery begins to die, the hands are no longer synced.
After replacing the battery, go into local time mode (pressing the center of the crystal) until "Set" appears. Press the crown. Scroll to "ECO BAT", press and hold the crown for 5 seconds until "SYNCHRO" appears. Use the "+" button to move the minute hand and the "-" to move the hour hand until they are in the upright or 12:00 position.
Either press the crown again or wait until the watch automatically leaves the Set mode. Your hands should now represent the local time.

The Tissot Touch watch is expected to need "SYNCHRONIZTION" periodically. (that is, to synchronize the digital and analog portions.) The Tissot manual tells how to do this. This manual came with your watch and is available online from the Tissot website.

good luck, Rodney

Syncronisation sequence is in the user manual. syncronisation is as follows.. 1) Press T to activate touch system. 2)touch the screen centre to show units display. 3)hold T button for approx 5 secs till the hands point to 12o clock. 4)use the + & - buttons to control the minute and hour hands... you must syncronise them both to 12 oclock exactly. 5)when you have them both pointing to 12 exactly, press the T button to finish the sync. the hands will now go back to the time. If the hands often go out of sync, the battery is probably worn and will at some stage the 'bat' warning will appear. (this initially only flashes every 20 secs, so watch the display for over 20 secs to see the 'bat' warning. eventyually this becomes permanant display). Batteries normally last about 6 years

there are sync instruction on the manual page on the web.

1. Activate the Crystal.
2. Select the "units Mode".
3. Press and hold the "T" until it switched to "syncro" mode.
4. Now using the + and - move the hands to the 12 o'clock position.
5. Press "T" again to set.

You are need to send it into tissot for a service. You cannot fix this problem on your own. There is a two year warranty for tissot. Hopefully you will be eligible.

it all stems from the watch not actually being waterproof it's more water resistant than waterproof. The little indentations on the back that look like they are for a tool to unscrew it are actually holes i guess for the altimeter and meteo so it can sense pressure. Behind the back just behind the holes is a nylon gauze material and underneath this is a sensor slightly recessed and covered with some kind of waterproof substance. As far as i can see the problems lie here any water sweat or other foreign object than gets into this gauze will eventually will clog this gauze material which at first will affect the altimeter then the meteo. When the gauze has been clogged up severely i gets very dirty indeed which means when it gets wet it takes an age to dry out so if you wear it in the shower like i used to it will never dry out this causes the watch to malfunction quite severely. You can actually fix this problem yourself just get a very small flat screwdriver and lever the back off don't worry it's only a push fit and comes of easily you will see straight away a dirty damp smelly clogged up round piece of nylon gauze clean this up with a bit of WARM not boiling soapy water being careful not to disturb the pressure sensor and it's waterproof goo inside then dry it all and put it together
Hope this helps

I have a similar problem which started this morning. My watch is almost 5 years old, and is on it's original battery. I suspect this is the first sign of the battery dying.
