Happy New Year, everyone! I hope you all had a great Christmas.

 

I'm working on an Elgin 554. After disassembly, I inspected the jewels and found the one where the fourth wheel passes through damaged.

 

I suspect I cracked it when I was removing the second hand connected to the fourth wheel pivot. I think as I was removing the second hand, the shoulder of the pivot pressed on the jewel.

 

The distortion on the jewel's surface - bent towards the dial side, supports this theory.

 

Question: I would like to seek your advise - How to remove the subdial hand without breaking the jewel?

 

I'm thinking, while the dial is still attached, pull the fourth wheel after removing the train bridge. What do you think?

 

Looking forward to your advise.

 

Cheers!

Joel

If the second hand isn't fused to the 4th wheel arbor, it should put that kind of stress on the back of the jewel. If it is fused, and can't be coaxed off the arbor without stressing jewel, maybe you could put a drop of thin oil, penetrant, on the top of the second hand, where the arbor passes. Maybe that would loosen the bond to make removal easier. That said, again, under normal circumstances, it shouldn't be that hard to remove the second hand. Good luck.

Thanks for the advice!

      Is this pallet fork over-locking?

      By Malocchio · Posted

      The entry jewel's not as bad but seems still too much lock. I do epilame the escape wheel and pallet jewels, then run dry for about 15 minutes, then put 9415 in exit jewel very little at a time and check with backlight how the oil's distributed.  Another question is about capped escape wheels. Should I somehow wear the epilame off the pivots before installing the wheel? I normally let the escape wheel run dry for that said 15 minutes when there's no cap jewel.

      Bezels - What am I doing wrong?

      By Malocchio · Posted

      Sometimes there's a certain place under the bezel where the case knife is supposed to be placed. In this borrowed pic there's a small crack at 3 o'clock.

      Bezels - What am I doing wrong?

      By Waggy · Posted

      Hi my fellow forum addicts, I'm writing this as I seem to have a hole in my knowledge (probably one of many!) I seem to have a horrible time removing bezels from watches. I am talking about the rotating type on sports/diving watches. I see many videos where the guy on screen barely inserts the case knife under the bezel and with no effort it pops off easily, then at the end it clicks back into place by hand with no effort. I am sure that part of this is due to skillful video editing, but I seem to wrestle with them, I have tried case knives and  even when using the tool below, I tighten it up in several positions and nothing happens. On a many occasions I have even warped the bezel in my attempts to remove it. Similarly, I have issues replacing bezels after cleaning etc. and often they have to be replaced using a press tool and inevitably are far too tight and will not rotate or loose to the point where they fall off or loose their click (perhaps due to micro warping when I tried to remove??). It is now to the point where I am actually avoiding watches with bezels as my success rate with them is terrible......please help!! In short I am asking: What am I doing wrong? What is the best method for removing bezels - how do you do it? What is the best method for replacing bezels - how do you do it? Any tips or tricks? Thanks

      Amplitude still seems low, but I'm going to let it run in a bit and revisit. Meanwhile, got the first layer of the calendar works together and made sure the date ring snaps to both in quickset and regular setting. The mechanism is pretty cool, so I took a video.

      This is the part that need replaced if anyone can point me in the right direction.
