Hi. The modern day clocks are built from different levels of brass and steel in order to cut costs and increase the profit margin , I have said before  the buying public are wowed by the look of it  aka fashion watches selling at 100 s of pounds all swish and nice powered by a Hattori plastic movement costing a few quid at most. Modern clocks are no better. You could put the best movement possible in a crappy case and it wouldn’t sell well.  Unfortunately it is the modern way, don’t like it but we have to accept it .

I think I am going to hit it with a little heat unless someone objects

Try manually running a narrow strip of thin paper or aluminium foil though between the wheel and the vane pinion & see how deep and sharp the impression is?

How sharp (or not) it corrugates the strip should hopefully allow the actual meshing depth to be seen?

Brand new. 

I just thought of one. Sinclair Harding but be careful there are fakes.

If you look the pin wheel & fly pinion are different from chime side  to strike side have you got them mixed up ?

Which model Hermle movement is it?  I've just grabbed some pics below from a couple of 340/341 movements I had lying around.  The strike side fly pinion is distinctly different from the chime side.  Can't say I've noticed before, as I think the shape of the fly blades prevents them from being interchangeable.

Please ignore the filthy pinions, these are spare movements that I havent touched yet :-).  

The first two pics are strike-side flys with a shorter, stubbier pinion. The second two are the chime flys, with longer, slender pinions.

Back in my other shop with all the parts of this clock. Look at the difference in the chime and strike pinions.opinions.

Manufacturing flaw??

So this picture from @LittleWatchShop shows the chime fly fitted to the plates, and the strike-pinion loose for comparison.  They look the same as the movements I have, with the exception that the teeth on this fly pinion don't look finished all the way to the end.  Not that it would affect the running of the clock as the wheel meshes at a point where the teeth look good.

Good point Dell that is why always use tubs to keep the parts separate.

Here is a closeup of the chime fly pinion. Notice the shape of the pinion left to right. Starting on the left with a larger outside diameter and then growing smaller as you move to the right.

If the pinion were consistent the left diameter, it would probably work.

I do not know which model this is because it is branded Seth Thomas on the plate.

Dell wins the day!

When I disassembled the clock, I intentionally kept the chime and strike side separate as I always do. I must have screwed up along the way and the warning wheels got switched.

The problem was compounded by me taking only part of the clock with me to my other location, limiting my ability to make comparisons.

At any rate, it is a screwup, no way to sugar coat it.

The pivot mounting lug looks well chewed up in this picture.  I suspect the pivot hole isn't at the correct position for the gears to engage properly, and needs to be reset to the correct depth with a depthing tool/manual adjustment.  From my pics above, this looks like a chime fly pinion and looks to be in the correct position (strike or chime) in your earlier comparison pic.  

@LittleWatchShop can you share a picture showing the full rear of the movement, please?

    • Recently inherited a box of my Grandfathers watches, nothing valuable, but some cool and some unique items.  Seiko SQ, my aunt went to Hong Kong in the 80's I believe and picked one up for my Dad and Grandpa. Below are picture, I believe its a 1987 5Y22-8A08. Put a new battery in it and it fired right up! Its probably been a drawer for 20+ years. Looks like he only wore it a few times.   Citizen Quartz 46-9181 with a seven jewel 7961B movement. It had what looked like some moisture damage, and a corroded battery. Swapped it with a 371 but it would only vibrate the second hand. Tried trouble shooting while in the case but eventually ended up pulling the movement out and cleaning with some naphtha and blowing it out and running it on the demagnetizer for a while to free up the movement before cleaning the band and case lightly oiling and reassembling everything. Now its back up and running. Based on the adjustment of the band I believe my Grandmother actually wore this watch, and I made the mistake of telling my wife that. Now its her watch! The most interesting so far is a 72-73 Benrus.  I tried putting a battery in it, but no joy. Ran it on my little tester, no signal from the coil, tried to spin it up. Just the slightest flicker of the second hand. Put some naphtha where I could reach, and tried again to spin it up. Nope. This watch is interesting in that it does not look like the back comes off, there is a window you unscrew to access the battery, a huge SR44. Ordered a crystal puller and will begin disassembly next week.  I was able to find a little bit about this watch though a google image search; BENRUS H010 TECHNIQUARTZ 1972 1st US made Quartz made by Benrus. Using a custom E-block with the step Motor, a power switch and a Moto Chip driven by MotoQ at 32KHz, on modified ETA mechanical movement. https://www.crazywatches.pl/benrus-h010-techniquartz-1972  
    • It’s done and the movement feats/aligns perfectly in the case. I stripped off 10mm wide sandpaper and wrapped /sticked it around the pad with double sided tape. I run with 400 grit and finished with 1000 grit. Now I can continue with my build, I’m going to buy a dial and hands. The dial I am considering is a larger diameter 36.5mm than the allotted space 35mm in the case, so I will apply the same ‘technique’ with sandpaper and Dremel/drill. Thank you @RichardHarris123, @AndyGSi and watchrepairtalk community for your help.    
    • As you're in the UK I suggest you look at Cousins for screwdriver sets as they've never cause me any problems. The key is the right blade, dressed correctly to suit the screw. https://www.cousinsuk.com/product/cousins-swiss-style-sets-rotating-stands https://www.cousinsuk.com/product/value-screwdriver-sets-wooden-cases https://www.cousinsuk.com/product/cousins-swiss-style-flat-stainless-steel
    • It's difficult to tell because of the dial ring but I expect it's the highest hand version they do know as a 'H6' The only way to be sure is to remove the hands and dial and measure the cannon pinion.
    • You're 100 % correct! I'm only interested in dissecting a counterfeit movement, and after that, destroying it. As a general rule, I would never buy, wear, or sell a counterfeit watch or movement. In this case, I'm willing to make an exception, as I want to get a feel for what a really good counterfeit feels like so I can better identify counterfeits. Thanks, that will be helpful! I absolutely see where you're coming from, and I'm basically in the same camp. However, I'm willing to make an exception if the purpose is to gain knowledge which will help to better combat counterfeits, and the movement isn't used for any other purpose than dissecting it and finally destroying it. Looking at the link provided by @GuyMontag most of the time we won't have any problem identifying a counterfeit. As experienced repairers of genuine Rolex movements, I would guess we would be able to identify a counterfeit in seconds. However, a well-made super clone of the movement might be harder to detect, and that's why I'm investigating the possibility of getting one. Thank you for your input and for helping clarify the situation — much appreciated. We’re right on topic. I’m currently servicing my second Rolex 3135 movement for a client, and I started this thread to document and discuss any issues or anomalies that may arise during the work. During disassembly, I encountered a few screws that, to me, appeared inconsistent with what I would think are typical Rolex finishing standards. This initially raised concerns that I might be dealing with a high-grade counterfeit or "super clone." Fortunately, those concerns were laid to rest, but the experience highlighted the importance of being able to reliably identify counterfeit components.
