Running dry is the easiest way to go here, and it will work, but ideally you want a tiny bit of lubrication in a couple places. Using a needle oiler, apply a microscopic amount of synthetic oil to each gear spindle in the slow speed escapement. Then apply the thinnest possible layer of moly grease to the contact surfaces of the speed selector ring (the layer should so thin as to be invisible to the eye).
Does it matter which kind of synthetic oil? My shutter assembly doesn't actually give me access to all the gears and contacts.
