Where is the serial number located on a Wenger Watch?

Do you have a model number? Most watches use a spring loaded pin that slots through the strap at the watch end. The two pairs of 'legs' at each end of the watch have dimples on the inside flat surfaces that the spring pushes the ends of the pin into. You mount one end into a dimple then push against the spring until it's short enough to drop into the opposite dimple. A real pain in the tailbone to do as the bits are so small but you can do it yourself.

I am thinking you are talking about a Wenger watch, so question edited from 'Wegnar' and the word 'watch' added.
Question moved from Cellphones category to Wenger Swiss Military Watch..

Are you a Watchmaker or a Jeweler? Have a read. My guess is wrong battery, wrong voltage, dead battery or reverse polarity, or bad connection.

Are you sure the number 33009 is correct?
Most Wenger watches have 5-digit numbers starting with 7.

There is a Swiss Military Manual here:

Take it to a jeweller. this is a good watch you may not want experiment on.

Make, model, all numbers, please.

Yeah, that's probably a battery that's about had it. eD

good day,
hope this link below will solve your problem.

Go to the Wenger web site (wenger.com).

Select "watches"

At the bottom of the page there are a number of tabs, select "services".

On the right hand side of the screen are two options below the search box, select "booklets"

Opposite "instruction's booklet" there is a small red tab, select this and the instruction booklet for all Wenger watches will appear.

Hate to say it but Wal-mart has the tools; seems like they'll do it for free if you buy the battery

Hi,

Maybe you can try above link to contact Swiss Wenger for the repair of your watch. It's best to send your valuable watch to its Authorized Dealer for repair.

Thank you.
