What Are Watch Batteries 329? A Practical Guide for Buyers and Businesses

If you\'re searching for what are Watch Batteries 329, there\'s a good chance you already have a reason to look them up. Maybe a watch stopped working. Maybe you\'re servicing several watches and need to replenish your battery drawer. Or perhaps you\'re a reseller trying to identify the right product before placing a larger order. Whatever brought you here, the important thing is that a 329 isn\'t simply “another small button battery.” The 329 is a silver oxide watch battery commonly identified as SR731SW. MicroBattery lists the 329 as a 1.55V cell, measuring approximately 7.9 mm in diameter and 3.1 mm in height. Its catalog includes 329 batteries from several manufacturers, giving buyers options when sourcing the same battery specification. That identification matters because watch batteries can look remarkably similar while having different dimensions and electrical characteristics. If you\'re buying one, selling them by the dozen, or stocking them for a repair business, getting the model right is the first step.
