I got turned onto perplxr's YouTube channel by another thread here. I spent 42 minutes of my Saturday morning watching this video http://youtu.be/Xnh7O22mduE. This caused my wife and both kids to question the state of my mental health. At any rate, it's a fascinating video but it left me wondering about the amount of lubrication being used. Maybe it's my lack of experience or the fact that much of the footage seems to be filmed at high magnification, but I really got the impression that the watchmaker used a LOT of lubricant. Any thoughts?

Well, the magnification does play in. However, if this is the video on the servicing of a hand wound Unitas, I think that the oiling of the pallet stones has been way overdone.

I don,t know if is the magnification or it is over lubed. The interesting bits for me was the way the mainspring was fitted with the abour already fitted in the barrel and the dynamic lubrication of the escapement. I have never seen these methods used before.

And no braking grease on the barrel wall!

Well Geo, now that you brought that up...I did apply grease to the inner walls of that 2824-2. I realized my mistake when winding it to get it started. It would only go a few winds and then slip! This repeated itself upon continuing to wind. I have seen various greases for lubricating the barrel walls and I imagined it needed it because of the great force exerted on those walls. None of Marks videos address this option that I am aware of, and in the ETA service sheet it only shows a complete barrel. I would like to know the official word on this.

Guys for the first time I lubricated a the barrel rim after watching the attached vid. If you look at my recent post re-Seiko barrel skim I lubed and the watch barrel rim as a fail safe and the watch runs great and winds great. I don,t think Mark uses this method but would be interested on what is the correct procedure.

I've got one thought ... when have you ever serviced a watch were the screws undo that easy, and the plates remove that smoothly :P

Ahhhh, we can only dream ^_^

At least I can get my fingers manicured! :)

:lolu: BAHAHAHAHAHA! :lolu:  The "Cleaner-Cam" at around 15:00 is FANTASTIC! I love it!

I am a bit weirded out by the mirrored work surface, but to each their own.

Very well made video, the spectacular camera work was so good as to be a distraction.

 

One part of this method raises a question for me which I would like to loosely address to the more experienced present. In this video, the screws all got chucked into the cleaner together. I've got a long history of repairing laptop computers, mobile phones, and other small electronics, where the screws can appear identical, but misplacement has disastrous consequence. As a result of this, I am very cautious about mapping screws to their original locations, and this has followed me into the watch world. In this method, should one assume that experience is the key which will ensure that this guy replaces all of the screws correctly? Does this movement use only a single specification screw? How does one tell during the course of any general work?

It is my understanding that braking grease is necessary only for mainsprings of automatic movements. The additional friction compensating for the lack of a fixed attachment point for the spring. Is this correct, or should braking grease be used in all mainspring barrels?

Hi rustycolt,

 

(IMHO) I believe experience with the movement you are working on could be a key to use the screws where they belong. In any case, keeping track of where they go is a good precaution since, as you said, misplacement could bring a lot of trouble!

 

Cheers,

You're absolutely correct, another huge dose of brain fade, I really shouldn't look at you tube when the grandchild is running about causing mayhem. It's been a bad week! :-)

perplxr always brings out great videos - just wish they would bring more :)

 

To comment on this video, I would add that the lubricant should be smeared in to reduce the risk of it being squashed down to the bottom of the barrel when inserting the spring. I personally would not have applied as much lubricant, but we all have our own techniques and theirs should be respected.

It's a good video but I do miss the excellent and useful commentaries I get with your videos, Mark. I was also wondering at the amount of lubricant used - but then I'm no expert.

A great video with some useful tips, an eye watering moment for me was when he was lubricating the pallett jewel while the escapement was in motion, one slight slip and game over. It takes a real expert for a technique like that...

      Calendar work certina 25-651

      By tonydagee · Posted

      Hello all, just disassembling to service, but I can’t figure out the working of the calendar work…it’s not operational the jumper and spring are ok, but the operation of the driving wheel has me at a loss. I can’t see a cam to drive anything. Is something damaged or missing? Help please!

      Unusual Seiko dial damage

      Believe the relume (not a fan) was done a long time after the damage.

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
