I started my first chronograph.  The plastic part seams to have a slight bend to it and is jamming things up.  I found parts of a parts list but it did not include this part. Does any one have a name and a part number for it?

Yes, one tech guide (older) shows it as #8200, a more recent ETA parts list shows it as "33 Var" , "lock, assembled" . Jules Borel lists it as blocking lever, #08200.7750.0. There are two versions, older ones are usually plastic, newer ones seems like they are always metal. Either will work fine.

      Hermle 340-020 slowing down as days go by

      By DirkP121 · Posted

      Update, I discovered that I could change the mainspring by removing the arbor and sliding it out from between the front and back plates. So I put a new mainspring in. This it what I  get over a 7 day period After winding                                          amplitude is 1 1/2 turns plus a few degrees.                                                                        ie just over 1 1/2 turns. 1 day after winding     gained 1 sec      no amplitude check. 2 days after winding   gained 1 sec      amplitude 1 1/2 turns                                                                                                              i.e. it lost the few extra degrees 3 days afer winding    gained 3 sec     no amplitude check 4 days after winding   gained 5 sec     amplitude 1 1/2 turns                                                                                                               i.e. unchanged 5 days after winding   gained 7 sec     no amplitude check 6 days after winding   gained 16sec    amplitude just over 1 1/4 turns 7 days after winding   gained 24sec   amplitude 1 1/4 turns. From  Based on video inspection, I am getting full pallet lock. So, my data seems to be at odds with the statement "swing of a balance wheel has nothing to do with the rate". However, I have noticed the banking posts are not controlling the lever position on the right side.  I may have some work to do here.

      Crown Snapped Off - Armani Renato Watch

      I can't tell whether or not some stem is stuck in the crown, I  think so though.  If the crown is stainless steel you could try alum to disolve the stem of try drilling it out. If all else fails, buy a new crown.

      Does anyone use the x5 eyepieces,  when i use them on my different amscope , the magnification changes to x5 but the field of view remains exactly the same as the x10, so nothing gained. The optical lenses can't be swapped out or at least they are not available as far as i know.

      I think maybe we're all a bit dim @ManSkirtBrew 🤣 99% of the time I'm working with the 0.5X Barlow, so mags from 3.5X to 22.5X. When I need a close up of a pivot or jewel, I take the Barlow out, and even put in the 2X Barlow, but it's a nuisance. So like you, I had that D'oh moment, why don't I just use 20X eyepieces (WF20X/10). They take seconds to change, and you keep the working distance. The only downsides are lower field of view, and less brightness.

      At the lowest magnification, I can just get all of a normal wristwatch size movement in field. For some things it's too much magnification, but the nice thing about the eyepieces is they only take seconds to swap in and out. I'm genuinely surprised I've never read about anyone else doing it, to be honest.
