No problem, this spring is an 'easy to make', out of guitar string... I wonder, how You know my name? Yes, it is in my nickname, but still I wonder... People know me in Bulgaria an may be in Russia, but this here is the first time I wrote something in english-writing forum...

Just look at the picture in my first post, there is the place of the spring, drown with red collor...

If i may ask, what was not running right? If it is the winding/settinf function, the problem usually is the fixing position of the winding stem, which is a part of the case, and, mast be adjusted there...

About 1880-1890. This is a cylindre movement, that means less accuracy and reliability. The collectors don' like them...

The most close caliber in dr Ranfft site is this http://www.ranfft.de/cgi-bin/bidfun-db.cgi?13&ranfft&&2uswk&Langendorf_2_19_sav But it is bigger... Even if You find another escape wheel from a donor or parts suplier, there is no full guaranty that it will fit well without correction of the palets. The easiest anf fastest waay to solve the problem is to repivot the broken pinion.

This can be confirmed only by his Grandfather... Or maybe, Grandfather bought anothet watch in 1870s...

Ofcourse, this is swiss movement. It is FHF/Fontainemelon ebauche modification of 19'''H6.5, similar to this http://www.ranfft.de/cgi-bin/bidfun-db.cgi?13&ranfft&&2uswk&Duerrstein_21 It is produced for sure after 1900, maybe 1910-20

Actually, making balance staff takes 0.5 - 1 hour. But this is after many uears of practice... This is in Bulgarian, but You can see the pictures... http://chasove.com/viewtopic.php?f=104&t=6833

I can't identify the calibre, thow i have seen alot. I will suguess that it will be easier to make a new staff then to find and buy one...

Hi there, Unfortunatelly, 3602A staff will not fit 3602. 3602A is a slim movement, the lenght of the staff is 2.95 mm, and the lenght of 3602 staff is 3.80 mm.
