This battery is the most commonly used watch battery and has a slightly lower capacity than a 376, beyond that they are identical. It was developed for watches without any additional functions, such as lights or an acoustic alarm. Also, this battery has the same dimensions as a LR66 alkaline coincell battery. But this silver oxide battery has a much higher capacity, which has the advantage of being able to power your watch for longer.
