The Seizaiken 303 / SR44SW fits any watch that takes a Renata 303, Varta V303, Duracell D303, Seiko SB-A9 or Citizen 280-08, or any battery with the IEC code SR44. It is 11.6 mm wide by 5.4 mm thick, and as an SW battery it is designed for low drain analogue watches. You may also see the alkaline sizes LR1154, LR44, AG13 and A76 quoted for the same watch. They are the same size, but this silver oxide battery keeps a steadier voltage and lasts noticeably longer.
