Those are the Days of the week in French.

LUN is short for "Lunes", spanisth for Monday. You will probably have MAR for Tuesday, MIE for Wednesday, JUE for Thursday, etc...

For Invicta chronographs to set the day you need to pull the crown out to position 3 (2nd click after releasing the crown/ furthest crown position/ same position to adjust time). You can only set the day by rotating the crown clockwise. Every 24 hours of clockwise rotation will move the day indicator forward 1 position (Mon>Tue, Tue>Wed, etc). If your watch is set one day ahead of the correct day (Its Tuesday but the watch displays Wednesday for example) you will need to rotate the crown clockwise through the entire remainder of the week in order to get to the correct day, you CANNOT rotate the crown counter-clockwise in order to move the indicator back a day.

You must be on the main phone on jack 01 to set time. You can determine if your phone is jack 01 by pressing PROGRAM and then pushing the number 6 on the dial pad. The phone will read the jack and extension number. When you have determined the jack 01 phone, do the following.

1. Push PROGRAM key
2. Dial "0"
3. Enter year (last 2 digits)
4. Enter month (01-12)
5. Enter day (01-31)
6. Enter day of week (Sun 0, Mon 1, Tue 2, Wed 3, Thu 4, Fri 5, Sat 6.)
7. Enter Hour (01-12)
8. Enter Minute (00-59)
9. Press 0 for AM 1 for PM
10. Press "AUTO DIAL/STORE" key
11. Push PROGRAM key to return to normal mode.

Some watches are designed to be international and thus have alternative names for the days of the week.

I think "mer, lun, dim" are Mon, Tues, Wed". It should be possible to re-set your watch to give the English version.

If you do not have a manual, you can get one from their web site "www.wengerna.com/mountaineer-titanium-72619" as a PDF file.

Well I think that the internet is down from your ISP side
Did you try to call the internet service provider ? Your ISP must be DSL .
with the message " ue Mar 09 13:06:51 2004 PPP network down [INFO] Tue Mar 09 13:06:51 2004 WAN interface is down [INFO] "
It seems that the internet is down on the modem.

Pull out the crown and advance hands forwards. When the hour and minute hand will pass 12 o'clock (midnight), you will notice the day hand will jump to the next (following) day. Advance hands as long as needed to reach the desired day.

Rate me, please.

At extension 1
press Program (mute light turns on)

dial "38"
enter 2 digit year, i.e. "08"

13=1 PM etc
enter 2 digit minute from "00" to "59"

You will hear a single confirmation beep. If not, you did something wrong. Start again from the top.
