1.5v to 1.35v DC in limited space

A watch I have used a 1.35v mercury battery. Now only 1.5v silver oxide
batteries are available. What can I use ( a diode maybe?) in this
confined space (11mm diameter x 4mm deep) to reduce the voltage to 1.35v?

Any suggestions appreciated

You might just try using 1.5v otherwise experiment with resistor values in
series

A 1N34,1N60 diode if you can fit it in will drop around 0.27 volt
Hope it helps

Thanks for the info. The watch runs fast with 1.5v and the mechanism
may be harmed. I was hoping to use a sub-miniature diode whose foward
voltage drop would put the voltage in my range. Anyone know the number
of such a diode?
Why dont you just get a rechargeable battery? - They are usually 1.2-1.3V
IIRC...
