Do not use (inherently low performing) "LR" alkaline batteries in place of silver oxide in any timepiece: alkaline batteries have declining power output.

1.55 volts 10mAh
Mercury Free

The 346 is a long life silver oxide chemistry with non-declining power output; alkaline batteries of the same 1.5 voltage start at 1.5 and at the half life are at .8 volts, silver oxide start at 1.55 volts and maintain the voltage until expiring. This is why silver oxide batteries are always used in watches, insulin pumps and sniper scopes or mission critical situations. Never use alkaline batteries for any device requiring a steady constant voltage. A watch with declining voltage cannot give the best performance.
