Hi Gabriel, First of all, You need to undrestand if the existing spring is correct or not. To do it, You will need to untwist it. In such twisted condition, the pendulim will oscillate much faster. Untwisting is possible, but it will be hard to bring the shape back to ideal. No mater, the pendulum will oscillate normally as if the spring is not twisted. You need to turn the pendulum in untwisting direction several turns thus twisting the spring in the other direction, then check what has hapenned and if more turning the pendulum is needed to improve the spring. As the spring will not untwist evenly, concentrate on it's upper part to untwist correctly. When it is done, grasp with tweezers under the rectified part and continue till all the lenght is done. Then You need to understand what is the needed period of the pendulum oscillations. I have seen 20, 15, 12 and 10 sec. Observe the minute hand while moving the fork left-right manually, see how many moves atre needed for the hand to shift 5 or 10 min ahead, then divide this to the moves counted. After knowing the period needed, You can use timer to measure the real period when the clock is working and thus You will know fast if the period can be regulated to the needed value or not, and if the spring needs to be replaced. Thinning the spring is possible to slow the clock down instead of replacing it. -

Dial washers are pretty generic. You can get an assorted pack from Cousins. https://www.cousinsuk.com/product/dial-washers-foils -

Hi gents. I got a used, but working SW330-1 movement. In order to assemble it, I need a dial spacer, since it didn't come with one. Since this movement is identical to the ETA 2893, I looked for dial spacers for these 2, but come up with nothing. There are, however, plenty of dial spacers for ETA 2824 and 2836. Will these fit? Thanks -
The suspension spring is wrong it should be dead straight with no twists or turns.. The strength of the spring is critical to strong or too weak and you will run out of adjustment. If can supply with the measurements of the movements back plate I can refer to my “Horolovar 400 day clock repair guide” book to give the exact spring you need..
