Replacing a watch battery may seem like a daunting task, but it’s a relatively straightforward process that can be completed in just a few minutes with the right tools and a little patience. Whether your watch has a screw-on or a snap-on case back, the basic steps remain the same. With a few simple steps, you can restore your watch to its former glory and keep it ticking for years to come.
Before you begin, gather the necessary tools, including a small screwdriver, a pair of tweezers, and a new watch battery. It’s essential to choose the correct battery for your watch, as the wrong size or voltage can damage the watch. If you’re unsure about the type of battery you need, refer to your watch’s manual or consult with a jeweler.
Next, determine the type of case back on your watch. If it’s a screw-on case back, you’ll need to use the screwdriver to carefully remove the screws around the edge of the case. Once the screws are removed, the case back will pop off, revealing the battery inside. If your watch has a snap-on case back, you’ll need to use your fingernails or a pair of tweezers to gently pry it open. Be careful not to damage the case or the watch itself.
Determine Battery Type
To replace a watch battery, the first step is to determine the type of battery it uses. This information can usually be found on the back of the watch or in the watch’s user manual. However, if you don’t have this information, you can try to identify the battery type by its size and shape.
Watch batteries come in a variety of sizes and shapes, but the most common types are button cells, which are small, round batteries. Button cells are typically used in watches, calculators, and other small electronic devices. The size of a button cell is typically designated by a number, such as 377 or 395. The first two digits of the number indicate the diameter of the battery in millimeters, and the last digit indicates the thickness of the battery in tenths of millimeters. For example, a 377 battery is 3.7 millimeters in diameter and 0.7 millimeters thick.
In addition to button cells, some watches also use coin cells, which are larger, flat batteries. Coin cells are typically used in larger watches, such as dive watches. The size of a coin cell is typically designated by a letter, such as CR2016 or CR2032. The first two letters of the number indicate the diameter of the battery in millimeters, and the last two digits indicate the thickness of the battery in tenths of millimeters. For example, a CR2016 battery is 20.1 millimeters in diameter and 1.6 millimeters thick.
| Battery Type | Size/Shape |
