Hello - I have a 1914 ST Adamantine with an 89c in it. I love the clock sound and everything about it. I am trying to figure out how to adjust the fast/slow setting so that it will keep good time - it seems to lose about 6 minutes between windings. (sunday to sunday) which direction to I turn this adjustment key? While I am at it there are a few chips in the adamantine that I would like to at least make look better. I am sure there is no way to restore these but what do you recommend that I use to help hide them? Thanks!
