This 344 or SR1136SW cell is low drain and unsuitable for power hungry devices such as watches with backlights, for which you require the high-drain 350. We may sometimes supply the higher capacity, but otherwise identical high-drain 350 cell in place of the 344,

The 343 is a mercuric oxide cell of the same dimension. The 343 mercury cells are no longer manufactured because of their toxicity and environmental unfriendliness. Although the electrical properties are slightly different, if your requirement is to replace a 343 or MR42, you have little option but to use this silver oxide 344 or SR1136SW in its place  One alternative that is specially designed for watches is the Accucell-1 battery with built in voltage reduction.
