I have a beautiful Seiko watch with 7009A 17J movement (automatic), the problem is that the watch stops when shaken and does not starts again until shaken again. 

What can be the underlying cause and is it an easy fix. P.S. I am a novice trying to learn

Hi there could be several reasons for the watch stopping , from being dry/dirty and needing servicing to a mechanical failure for example a broken balance staff,   pallet/fork fault faulty wheel or wheels.    broken / damaged mainspring, the list goes on. Without opening the watch up the watch  and taking a look, sorry cant be more specific at this point   cheers

I remove the rotor and put some naphta on screwdriver, gently smear each teeth of the escapement wheel with naphta and all jewels to the escape mech, that is jewels to the es apement pivots , fork pivots and balance pivots. 

Misaligned pallet jewels stops a watch on wrist and it can start to run again. we,ll get to that next.

      Put the movement in a movement holder and it will be supported as you push down on the setting lever post to release the winding stem. Make sure the post is over the shoulder of the movement holder so what you are pressing down on is supported. As a general rule, hold the movement and not the movement holder. Replace the hands when the movement isn't in the case and support the centre jewel (if it has one) on a hard surface or staking block when replacing the hands to stop the jewel accidentally moving or even coming out. A dedicated movement holder with a central jewel support is even better, but pricey

      It might help us if we knew which watch like model number.

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.

      Main spring

      By Jon · Posted

      I would go for the dearer spring. You won't need to remove the spring from the carrier ring and then use a mainspring winder to get it into the barrel, for a start. Also that spring is closer to the needed dimensions, especially the length. The length plays a part in the mainsprings strength. If you double the length you will half the force (strength) of the spring and vice-versa. A spring with 20 mm less length would be about 7% shorter, so technically would be 7% more strength, but I find halving this number is closer to real-world findings, so the spring would be about 3 to 4% more strength/force. On a mainspring that ideally kicks out 300 degrees of amplitude, a 3% increase in amplitude would be 309 degrees. Increasing or decreasing the length of the mainspring will affect the power reserve to a greater or lesser degree. It depends how much shorter or longer it is. I've attached a lesson regarding mainsprings, focussing on the size and strength of the spring within the barrel, you might find helpful. Unfortunately it is a PDF converted from a PowerPoint presentation, but only a slide was lost that was originally a video of fitting a mainspring   Lesson 5 The mainspring.pdf
