I was replacing the battery of my Citizen Eco Drice perpetual Calendar caliber 8700 watch. I successfully replaced the battery but the watch is still not working , is there an AC reset that I need to do or any other step that I am missing . Attaching pics for r reference

Hello Rishah, have you checked voltage on the new capacitor, even though it's new it can be low voltage from long time storage. There is a 2button reset procedure. But I doubt weather that would fix it if it's not going. You could try by putting that capacitor in and place the Watch in direct sunlight on your window ledge for a day or so to receive a full charge. Was the Watch working before at all? Citizen recommend that you fully charge your 8700 watch before use. Hope that helps.

one of the problems with quartz watches is the assumption that changing the battery will always fix the problem but it will only do that if that is the problem.

then when changing batteries in a quartz watch it's always a good idea to measure the voltage of the battery you're taking out. This would tell you if the batteries the problem or not.

as this is a rechargeable lithium battery it would be a good idea to check to see that the new one is indeed good because they will lose their charge over time. Fortunately you don't have to take it out I snipped out something from the service manual you can check the condition of the battery in the watch. If the battery voltage is too low in the watch go ahead and place it under a source of light and charge it up then check the voltage again. It may just be discharged and needs to be charged up.

Then if you having any more problems I've attached the service manual.

I have come across this before with Seiko solar and it did not charge with new battery and I discovered that the connection between the solar panel and the dial had become disconnected. This is common. But let's try charging on window ledge for at least 12 hours in sunlight first

      Is this a 'hack' ?

      By nevenbekriev · Posted

      OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.

      Any tips to correct a sloppy error?

      Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.

      Setting lever spring

      By mikepilk · Posted

      The stress is the force (on the spring) x distance. The maximum stress is at the bottom, and decreases up the arm. That's why they always break at the bottom. I used a round file, then something like 2000 grit to finish. I gave the rest of the arm a quick polish - no need for a perfect finish. Just make sure there are no 'notches' left from cutting/filing. The notches act like the perforations in your toilet paper 🤣

      It's probably a cardinal rule for watch repair to never get distracted while at the bench. Yesterday, after finishing a tricky mainspring winding/barrel insertion (I didn't have a winder and arbor that fit very well) I mentally shifted down a gear once that hurdle was passed. There were other things going on in the room as I put the barrel and cover into the barrel closer and pressed to get that satisfying snap. But when I took it out I realized I never placed the arbor.  When opening a barrel, we are relying on the arbor to transfer a concentrically-distributed force right where it is needed at the internal center of the lid. However, when that isn't present it's difficult to apply pressure or get leverage considering the recessed position of the lid, the small holes in the barrel and the presence of the mainspring coils. It was a beat-up practice movement so I didn't take a lot of time to think it over and I pushed it out using a short right-angle dental probe placed in from the bottom, but that did leave a bit of a scratch and crease in the thin lid. I had also thought about pulling it using a course-threaded screw with a minor thread diameter smaller than the lid hole and a major diameter larger, but that may have done some damage as well.  Thinking about how this might have been handled had it been a more valuable movement, is there a method using watchmaking or other tools that should extract the lid with the least damage?

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      🤔 what happens if lubrication is placed directly on top of epilame ? Making a small groove so the lubrication doesn't spread across the component but what if when lubing a little overspills and sits on the epilame .
