Components of a Pocket Watch
Hello everyone! Happy Friday the 13th!

This is the next installment in a series of "Helping Hand" tutorials. In this lesson, we cover the basic components of an Elgin 16s pocket watch. There will be a few components for which Elgin used different terms but the vast majority are the same as other companies. As you will see, I've learned a little more of that HTML stuff. Hopefully, my skills at this will improve in future presentations.

I would like to thank Steve Maddox and Ed Ueberall for their technical review of this presentation.

ENJOY!

This was excellent and very well done i hope to see more in the futureI especially liked the names and what the factory names and the usual names watch repair people use.

As usual, John has done a fantastic job!

I know something about the time and effort involved in creating a presentation such as that, and John deserves much credit, as well as our sincerest appreciation!

I hope everyone realizes that no one was paid a cent for the work above, it was created through the generosity of a fellow member and enthusiast, whose only desire was to assist those less informed.

If anyone ever has doubt about the character of watch and clock collectors, efforts like that should stand as a shining example.

For those who sometimes wonder, THAT is what the ***** was supposed to be about and now the IHC is!

JOHN, Your slideshow was GREAT! Even i learned something new, i have a sleeve wrench and never knew where it went and what it did, NOT that i'm going to use it any time soon Roll Eyes

THANK YOU VERY MUCH, LOOKING FORWARD TO MORE Wink

I noticed that John's tutorials already have 500 'views' between them. Their popularity shows that he has done a fine job with them and that they fill a real educational need to both advanced collectors and those just getting interested in learning about horology.

John D,

Simply put "that was great". Cool It almost makes me want to take a pocket watch apart. Slide show gives encouragement. Smile

I have a suggestion. I'd like to see a slide show of components of a wristwatch. Here's why. I have a Lord Elgin wristwatch which I tinkered with one day when I was feeling confident. Big mistake on my part. Now mind you, I know nothing about repair of pocket watches or wristwatches. As a result, somehow the hairspring came loose. Now as a lay person in the field of watch repair, do you think I can fix it myself? Confused

I'd hate to have to answer that question directly, Steph, but I will say this:

Hairspring work is probably the most challenging aspect of watch work, even among experts.

Stephanie,

I must say up front that most of my repair experiences have been with pocket watches. Pocket watch parts are larger and somewhat easier to work with. I have yet to perform many of the repairs taught in watchmaking schools but with
experience gained daily, I will eventually accomplish most of them.

The majority of all watches, wrist and pocket, discussed in our chapter have basic parts that serve the same function. Their packaging, however, can be quite different. In fact, many of the early wristwatches made by American companies were repackaged 0 and 3/0 size pocket watch movements.

Since my experience with wristwatches is limited, most of the presentations will revolve around pocket watches. With the continuing growth of our chapter, we hope that someone in the "wrist" community will eventually come forward and begin posting presentations tailored to wristwatches.

Now for your Lord Elgin. If it is your desire to repair the LE, we (IHC) are here to help and encourage you every step of the way. All that is required by you is the willingness to devote the necessary time and resources to a fascinating and
rewarding hobby. For every success, you will have two failures. You will begin a project, give it up, only to return again. You will be on your hands and knees looking for parts invisible to the naked eye. You will curse, you will experience total frustration but you will return.

If you decide that diving into a watch to see what makes it tick is your next step in the world of horology, then may I suggest that you first practice on the Official IHC Pratice Watch? Scott Cerullo is currently training on this watch. When Scott gets tired of taking it apart and putting it back together, it can be your turn.

In the mean time, study as many books and video tapes as you can about watch repair. Last but far from least, invest in a quality set of screw drivers, tweezers and magnifiers. These are the basic essentials to get started with. Above all, ask questions! Always remember that the only dumb question is the one not asked.

As Steve indirectly suggested, put the Lord Elgin back in the drawer for the time being and first concentrate on the basics.

We are all rooting for you! Hip-hip hooray!! Smile

Hairsprings a complex component of watches huh? I would go and have to mess up my Elgin Deluxe, model 555, 4 adj. 17 jeweled, 10K gold filled wristwatch. Frown Frown

John Du.

I do need to check into looking at videos and purchasing a few tools if I plan to start tinkering. Actually, there was some problem with the watch before I looked at the movement. Just thought I could fix it, can you believe that? Silly me. Roll Eyes

Hopefully, someday, I will get on the IHC list to take apart and put back the Elgin watch Scott is presently working on. Smile

Thanks

That is the FIRST time I have ever seen a complete description of the innards of a pocket watch.
What made it a compensated balance wheel John ?
Was it the split rim or the bi-metalic aspect?
Really enjoyed it

Take care

Ken,

Actually both. To quote from the War Department Technical Manual TM 9-1575: "The bimetal balance wheel cut at opposite points, which causes an automatic temperature correction to counteract the variation of the hairspring action caused by heat and cold".

Early watches used a solid balance wheel. Depending upon the ambient temperature and its effect on the steel hairspring, the watch might run fast, slow or keep reasonably accurate time. To "compensate" for varying temperatures, which affected accuracy, the compensated balance was introduced. Around the late 1930's, new alloys were being developed to create hairsprings that were relatively unaffected by temperature. With the use of these new hairsprings, the solid balance returned.

Something I’ve wondered: Apart from concern for authenticity, when you’re replacing a hairspring in an early watch will only a steel hairspring work or could you choose an alloy hairspring in order to gain its temperature-invariability and anti-magnetic advantages?

Dog,

If the balance was the old solid type, you might be able to vibrate an alloy hairspring and have a watch that would be less affected by temperature. However, if you used the same alloy spring on a split balance, you would again have an accuracy problem due to temperature variations effecting the balance wheel instead of the hairspring.

Hi John
Couple of things.
Thanks for replying to my post re the balance wheel, I'm still only stumbling blindly around the site and hadn't set my "pop it" preferences to notify me of replies.
My post on the balance wheel was a clunky question when I look back, as, the split rim and the bi-metallic element really are one item (hopefully Smile ) no good using bi-metals when the expansion has no place to go (Doh!)
I meant the screws around the wheel, do they adjust to alter timing?
As a horology newbie I think that every time I learn anything I can view your tutorials in a different light; they will expand on my meagre facts and increase in their importance for me.
To expand on something you mention elsewhere
F11 gets rid of toolbar at the top of the screen temporarily,and unlocking the taskbar gets rid of the bar at the bottom temporarily, giving a bigger screen area.
Finally John I am on XP home and a right click on the desktop whilst viewing the slides allows me to "zoom in" to enlarge your already superb pictures.

Thanks for listening John

John, as everyone has said, the amount of work involved in these presentations is tremendous.

Could I ask a dumb question? Inthe tutorial for replacing a sleeve and stem, you begin with the watch body and sleeve. How do you separate the watch body from the movement? Or do you actually do the replacement with the movement in place?

Also, the winding mechanism on my watch seems to go directly into the area where the balance cock ends. Is this odd? Confused Confused It is supposedly a waltham of some not particularly unusual type.

Sorry to be so dumb. Don't tell Steve Maddox, he's already sufficiently convinced of my hopelessness.

Jessica

Hi Jessica,

When you are referring to the "watch body", do you mean the watch case?

Also, what do you mean by "the winding mechanism on my watch seems to go directly into the area where the balance cock ends."?
May 19, 2004, 11:42
Jessica Lane
Hi. I meant the case had three parts: the back, the bezel and a part to which the stem, pendant and crown were affixed, or at least through which they went. You seemed to detach this third part from the others, or to disassemble the case into three parts.

Actually, by now, I've gotten the dial off, and my case is in three parts but, the pendant, crown and stem are attached (?). I'll loook at your tutorial again. Maybe I don't need to get them off, or maybe I should start with the sleeve puller?

I'll let you know if I can't figure it out.

Jessica,

Review this slide and the stem/sleeve presentation. It should help answer your questions. Once again, if you're not sure how to take something apart, don't! Eek
