There's no tech guide for these old calibers, just a part list if you're lucky. You might find a guide for an A. Schild alarm movement, should help a little. Pretty much a normal watch. You need to lubricate the alarm escapement with something heavy like 8300. All moving parts in the alarm system need a bit of lubrication, when in doubt use 9020 or HP1000, and too little is better than too much. Take pics, there are a lot of parts on the dial side. As I recall the set lever and bridge and winding parts are either the same or mirror image and easy enough.
