RunesS Skrev:Lækre sager, Hannover!!

De der lommeure af den "amerikanske type" med safety pinion, "kæmpe" chatoner og de der guilloche agtige slibninger er så charmerende!

Yep - Geneve bygget til USA, men hvad er en safety pinion mon for en fidus?
Hups fandt det selv
(horology) A center pinion gear in a watch that protects delicate parts by unscrewing when the mainspring breaks, thereby preventing pressure from being applied to the train wheel teeth and arbor pivots.
