One has to crack open the back cover using a knife as a lever. Initially, one will have to position the knife at the point the cover meets the casing. A few taps on the knife with a small hammer will crack the cover partly open. Then reposition the knife or use a small screwdriver to lever it fully open. Be careful not to force the knife into the movement. The battery is usually a 1.55 volt silver oxide cell, such as a Renata 394. Replace with a fresh battery (e.g. a 394) and close the back cover using a few taps with a small hammer.
It last about 3 years, I had my Swiss army field watch 10 years and it is great! I use sony batteries.
The Wenger Swiss army watch takes a MAXELL 396 SR726W battery. This is a very common watch battery so it is easy to find for sale.

Two types of batteries go into the watch. There are two (stacked) CR2016 that power the light, and then there is one 371 battery watch that powers the watch movement.
Unlike the Swiss Army knife, the Swiss Army watch does not have a wide array of functions. The watches tell the time and date. They may also have a light built in and a stopwatch function.
I checked with a jeweler and he said that you pull the stem out and that releases the crown where the battery can be accessed....he advised to let a jeweler do it.

There are several different options in order to buy a great looking Swiss Army Pocket Watch. Some examples of shops include "Overstock" (in section "Jewelry & Watches" - "Watches" - "Men's Watches" - "Swiss Army") and of course the official web shop of "Victorinox".
Swiss Army watches are available at stores like Target and Walmart. For more information, see the Swiss Army website, which provides a "Store Locator" function.
A good quality Swiss Army watch is worth anywhere from $150-$250 if you sell it to the right person. Some of them may even be worth almost $2,000.
Swiss Army watches have bands made from a variety of materials. Leather is probably the most popular product for watch bands. However, Swiss Army also has watches with bands made of webbing, steel, rubber, and of course, gold and silver.
A classic stainless steel Swiss army watch with black leather will vary in worth. It generally depends on the overall condition of the watch. If it's in near-perfect condition, you may be able to get at least $1,000 for it.
