Rethinking my earlier response . . . There's no reason the 1 volt
really has to be stable. If a DC/DC converter derives its power from
the battery its own output will track the battery voltage.
If you used a simple two transistor push-pull oscillator on a ferrite
core you could just wind it for the V out you need - or a little
higher so you have some adjustment range, and float that on top of the
battery voltage
