what is the battery size for a wenger swiss military watch 79149
my ASPEN watch actually has two batteries. There is a metal plate with a CR2016 battery beneath it but there is a 2nd battery compartment and I do not know which battery it requires.
Sr920
Energizer 377
either SP925 (SR927Sw) or an SP371
626 or 377
Try turning the watch over and carefully reading the back of the case. Many watch brands actually list the battery number on the back of the case. For instance, the numbers 377 or 2010 are standard watch battery designations. Since the size and shape of the dial does not determine the battery used, for best results take the watch to a local jeweler to have the battery replaced.
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.
You can find the correct size by going on the Timex Expedition website, and finding the correct watch model. It will also give you ways to buy the battery if needed. Good luck!
2.5 inches
Either a 395 or SR927 these should be replacements for each other
It is simplest to have your local jeweler change it because one never knows the size battery to put in. There are several size batteries and they are all small. Also there are retaining arms and/or springs to consider, waterproof rings to recover, ect. Now, having said that, this is how you do it. Using a very thin blade, gently prise the back cover off the watch. Inside you will find a tiny round object. It is the battery, there is no other round thing inside that you can access without damaging the watch. Carefully remove the battery, using a toothpick or your fingernail. Most times it will pop up at the slightest pressure. Examine the battery for the size number. Common sizes are 379, 2020, 376, or 619. Buy exactly the same size as a "close" will not fit the watch. Remove the card, insert the battery and replace the watch backing, being careful to align the marks again properly. Make sure you hear a "snap" or "click" indicating that the case is closed.
