We have been learning about the hairsprings as you know, now we have gone a little bit further into that and learned the second pinning so we have to do it all over again hehe.
The other day we ordered the Antique Watch Restoration nr. 3 by Archie B. Perkins from AWCI in the USA and we received them this week, very good book to own if you like restoration, And thank you AWCI for the friendly and fast service!
Last weekend Eero was here, he was learning how to use the profile projector to restore a balance bridge, by drawing the missing piece on a tracing paper and measuring the correct dimensions from it.
Hope you will have a good weekend.
