According to Gene Poon, ALL Spotmatics use a bridge circuitry, hence no
problems at all with 1.5V batteries.

I don't know, I've only had experience with models from the Spotmatic II
on. They could, but I don't know when Pentax started using the bridge
circuitry for their meters.

Do you mean early Spotmatics would not give accurate metering with a 1.5V

Spotmatics were originally designed to use a single 1.35 volt 625 or
PX13(?) mercury cell. Later models were designed to give correct meter
readings with 1.5 volt replacements as well.
