Case bezel opening question

Hi, so I'm new here, I've posted in the intro forum, and as mentioned I found this forum while looking for a solution to opening a case. 

I've built a couple of watches using parts from e ay and aliexpress, after watching the videos by Mark. 

One case came in 3 parts, the crystal is in a bezel and is push fit, the dial with movement attached goes in through the top of the case and the bezel pushes in last, after setting the hands etc. The issue I have is that the second hand slightly rubs against the inside of the crystal and causes jerky movement. 

I can't figure out how to get the bezel back off so I can take the movement off and fit a slightly thicker spacer. 

 

There's no obvious recess to use to pry it, and the fit is so good I can't get a blade in apart from very slightly on one side, but not enough to actually get any force in there to pry it. I'm thinking maybe I need one of those pry tools that's like a vise? 

Here's a photo of the case.

 Possibly not as drastic as shortening the shaft just reseating the second hand onto the shaft....Perhaps you bent it up slightly on assembly. Please be careful using razor blades or pen knives to open case backs. One slip can cause a lot of pain......I know from experience!!!

A case knife should do the trick. On many cases you can see a little channel that looks as if a case knife might fit in. Be very careful and see if the hand can be pushed on a little more, make sure you do not bend or break the pivot. A tiny bit of watch grease on the tip might help when pushing on. If you try shorten the shaft of the hand you will more likely close the hole over. If you have the correct size watch reamer you could open it out, But you might also loosen the pipe from the hand.

      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.

      What tools does ebay have to offer this week.

      I recently bought this but not on ebay. I figured if I want something Japanese I better check Japanese auction sites since these don't seem to pop up on ebay. I paid 83 € plus shipping & taxes. I think it was pretty reasonable for a complete set in good condition.

      Did you take the friction pinion off the large driving wheel and grease it? Although, now that I think about it, that shouldn't have any effect on the free running of the train if the friction pinion isn't interacting withe minute wheel/setting wheel...

      I did in fact use Rodico to get the spring into general position and "hold" it there while I used a fine oiler to make subtle positional adjustments.

      The two measurements of particular importance wound be the height and the strength,  the length would obviously correspond with the increase/reduction of half mm of barrel diameter. There is a big difference in price considering that the more expensive one is the shortest. The longer one might be ok ? But then it is taking up more room in the barrel, might it effect the unwinding ? I wouldn't have thought so for just that small amount.  Ideally a pro might reduce the longer one to suit. But there is some information that might help, do you have the one that was fitted to measure up, though not necessarily the right one.
