Hi everyone !
I got quick question about Venus 170 at first the hands are stiff to turn so I put oil on the pivot, and is trun freely , but now the gear probably hade to much lubricate and cause the gear to run free ( hours hand and minute not move) do I have to remove the oli by cleaning the gear or is maybe a different problem like loosen and need to tighten up ?
Thank you !
as you suspected, it's the wrong spring. As suggested above, I checked the Ranfft site (a bit tricky to navigate from the homepage - click the "pink pages" button, then "archive", then in the category list "Archive: Watch Movements", then search for AS 1700. The mainspring is listed as Zf675, 1.20 x 9.5 x 0.10 x 315mm. You appear to have been sold a 3mm deep spring instead of 1.2mm.
