A highly unusual and maybe even rare form movement (and an equally mysterious manufacturer) is the Tschudin caliber 25/19, which is completely unmarked, but could be doubtless identified with the Flume Werksucher of 1947.
The rectangular and stricly geometric cut form movement has got a size of 8 1/4 x 11 lignes and is so well constructed (it contains 15 Jewels), that it still runs, even after is was heavily affected by water damage.
