Need a new barometer/clock

[AntarcticPilot]

I never thought of replacing the clock mechanism. A quick trip to ebay confirms that I probably can replace the clock innards for a couple of pounds - never thought of that!

Actually, the only thing wrong with the barometer is that the reference pointer (the one you move to indicate the last reading) has disappeared. Heaven only knows where it's gone (it's not in the unit as far as I can tell). I suppose I could make a new pointer too....

If you've got a mechanical movement, for goodness sake keep it! I am sure that all it would need to make it work is a good clean; don't lubricate it except (perhaps) for the tiniest drop of clock oil.
