Master Watchmaking
A Modern, Complete, Practical Course

The Chicago School of Watchmaking was founded in 1908 by Thomas b. Sweazey.
LESSON 2: CROWNS, STEMS, SLEEVES AND BOWS
There are two types of part assortments available: bulk assortments which are not separated. And pre-sorted assortments, which cost more, but are easier to use.
In American watches there are three types of setting arrangements:
The first is the pendant set which uses s stem and sleeve and sits inside the watchcase and is sometimes called a Negative Setting.
The second type of setting is called a Swiss setting and the stem is a part of the movement and is sometimes called a Positive Setting.
The third type of setting is called a lever set and it uses a set lever operated by the finger nail and is mostly used in railroad watches.
Section 49:
A sleeve is screwed inside the watchcase pendant. The top of the sleeve is threaded, as is the upper part of the pendant inside. The sleeve with the stem inside is screwed into the watchcase pendant with a sleeve wrench. The bottom of the sleeve is sectioned like four fingers, which grip the bottom of the stem in two places; the bottom notch for winding and the top notch for setting. The crown is screwed onto the top of the stem, which is threaded.
Section 42:
When removing a movement from a case which has full head screws, you need only remove the lower screw, loosen the top screw slightly, pull up the crown into the setting position and the movement will come out of the case.
Section 43:
To remove the crown from the stem, after the movement has been removed from the case, hold the winding square with a pair of flat nose pliers and turn the crown to the left with your right hand.
Section 44:
Sleeve wrenches have prongs with either two, or four lugs on the ends of the prongs. The wrench is placed inside the pendant of the watchcase to unscrew the sleeve. On some watches, the sleeve is old and cannot be removed with the sleeve wrench. In this case, remove the stem from the sleeve and use a square file, or broach to unscrew the sleeve from the pendant. Adjustments are done to the sleeve inside the pendant, with the stem still inside the sleeve.
Section 45:
Using the sleeve wrench, place the correct size prong inside the pendant and turn the wrench to the left and continue doing so until the sleeve is free of the pendant and case. the, remove the stem through the bottom of the sleeve.
Section 47:
When selecting a new sleeve, make sure the diameter of the threaded top is correct, that the threads are the correct pitch and that the length is correct.
Section 48:
If a thread breaks off inside the crown which is made of gold, rolled gold, gold plate, or nickle, soak the crown in a solution of water and alum to dissolve the steel thread.
Section 49:
When replacing the crown, make sure the threads fit the stem threads and fits over the pendant.

Godzilla Says...
BURN HOLLYWOOD, BURN!
Here's a video of me removing and replacing a movement from a case.
It's my first video, so cut me some slack, ok 8^)
Check out the Homer Simpson moment at 1 minute 12 seconds; that case back was going on one way, or another!
It's a big file, over 28 megs, so give it some time to load.
You can also download the file from Rapid Share for free, just follow the link:

Chicago School Of Watchmaking Lesson 1
Master Watchmaking
A Modern, Complete, Practical Course
By Thomas B. Sweazey and Byron G. Sweazey.
The Chicago School of Watchmaking was founded in 1908 by Thomas b. Sweazey.
LESSON 1: FUNDAMENTAL PRACTICES, EQUIPMENT AND CASING
Section 3:
Master every job and all steps and speed will come with experience.
Section 12:
The first watch was made in 1500. In 1587 watchmaking as an industry was introduced in Geneva, Switzerland by Charles Cusin.
In 1635, enameling was invented by Paul Viet, a Frenchman.
The balance was introduced in 1658. While the minute hand came in to use in 1687. In 1700, jewels began to be used to support gear pivots.
The compensating balance was introduced in 1749, while in 1780 the seconds hand was created.
Section 13:
In 1819, Aaron L. Dennison began building watches by machine. His method of measurement was derived from the English measurement of 1 inch and 30th of an inch.
Dennison used 6|30 of an inch for the "fall". The fall was used by English watchmakers, making the pillar plate small enough to fit into the handmade watchcase.
With 1|30 being the measurement, an 18 size watch would measure 1 inch and 6|30 of an inch for the fall and 18|30 of an inch for the watch size; so the total size would then be 1 inch and 24|30 of an inch.
For watches which are 16 size, down to 0 size, (oh size, or naught size) the measurement is 5|30 of an inch for the fall. So a 16s would measure 1 inch plus 5|30 plus 16|30 making the total measurement 1 inch and 21|30 inch.
Dennison decided to move his factory from Boston to Waltham in 1851.
Section 16:
Screws were used on the pillar plate at the four o'clock position, while a pin was placed diagonally across at the 10 o'clock position in order to hold the movement inside the case, but also to make aligning the 12 hour marker directly center of the pendant easier.
Section 17:
Eventually screws were made long enough, that they could be screwed through both the top plate and bottom plate to hold the movement in the case. The problem with half head screws of tempered metal, is that the constant turning of the screws milled away the portion of the watch case, needing a washer to hold the movement in the case. This was remedied by introducing full head screws, which require removing the entire full head screws from the plates before removing the movement from the case.
Section 19:
The hunter case is comprised of several parts: The front and back lids and the cap are all held to the center by hinges, or joints, the bezel is snapped onto the center.
Section 22:
On snap back cases, a small lip, or cut out is present, so that a thin blade, or case knife may be inserted under the lip, or into the cut out to pry open the front and back. When replacing the front and back lids, the lip, or cut out should be slightly right of the crown.
Section 23:
Shaped cases are built with a key or pin in the center which fits onto the key seat. When replacing the back and bezel, it is important to make sure the key seat is directly over the key.
Section 24:
Swing out cases have a dust proof crown, stem and sleeve. Under the crown is a nut that screws down onto the outside of pendant and under this nut is a leather washer. To make adjustments to the sleeve, you must first unscrew the crown from the stem and then unscrew the nut off the pendant.
Section 29:
In older style cases for lever set movements, there is no sleeve. To remove the stem, you must unscrew the screw located on the pendant just enough, to be able to pull out the stem using the crown.
Section 33:
When trying to remove a movement from a case that is stuck, use the right thumb nail to apply pressure on the movement to ease it out of the case onto your waiting hand.
Section 34:
When taking a movement out of the case, or picking up a movement, be sure to use watch paper to avoid leaving prints on the dial, or movement.
Section 36:
When polishing a badly tarnished watchcase using a red cloth, blow some breath onto the case to moisten it to help with the polishing.
Section 38:
To replace the movement in the case, put the movement in by starting the stem in the winding arbor and fitting the movement into place. Then, while holding the dial side with the nail of your first finger on your left hand, turn the case over and place the movement screws in their slots and screw them in.
Section 39:
Place the crown into the winding position and turn it to be sure the movement is perfectly centered. Then screw in the movement screws just tight enough to keep the movement in place.
TEST QUESTIONS
Assignment No. 2: Sections 12-25
Q1. How are sizes of American watches determined?
A1. American watch sizes are determined by using the English 30th of an inch. An 18 size movement would be 1 inch plus 6|30 of an inch for the fall and 18|30 of an inch for the watch size, for a total of 1 and 24|30th of an inch. A 16 size, down to a 0 size would be 1 inch plus 5|30th of an inch for the fall plus 16|30 of an inch for the watch size, for a total of 1 and 21|30th of an inch.
Q2. What is a case screw and what is its purpose?
A2. A case screw is used to hold the movement inside the watchcase.
Q3. Why are full head case screws considered better than half head?
A3. Full head screws are better than half head screws because the screw is made of milled steel and can wear away the case. A full head screw will not.
Q4. What is the crown and what is its purpose?
A4. The crown sits atop the pendant and is used to set the time and wind the mainspring.
Q5. What is a bezel?
A5. The bezel holds the crystal and sits on top of the watchcase center, protecting the dial and hands.
Q6. Why are screw bezels and snap bezels so called?
A6. A screw bezel screws onto threads located on the case center. A snap bezel snaps tightly onto the case center.
Q7. What is a screw back?
A7. A screw back is a watchcase with threads on the center, so the back may be screwed on.
Q8. What is a back back?
A8. A back back is what the watchcase back cover is properly called.
Q9. What is the center?
A9. The center is the middle of the watchcase where the bezel and back attach to.

A1. The tools required to remove and replace a movement in its case are a screwdriver, tweezers and watch paper.
Q2. What is the right way to hold and use screw drivers?
A2. The right way to hold and use a screw driver is by holding the shank between the thumb and middle finger, with the forefinger on the top twisting the screw driver with the thumb and middle finger. It may also be held with the top in the palm and the thumb, middle and fore finger on the shank twisting the screw driver.
Q3. What is the correct way to hold tweezers?
A3. The correct way to hold tweezers is by resting them on the middle finger and using the thumb and forefinger on the blades. Also, you may hold the blades between the thumb and forefinger, with the butt of the shank in the palm.
Q4. What steps are necessary to remove and replace a movement in the case?
A4a. To remove and replace a movement in the case, first unscrew the front back and back back, or snap them off, if a snap back case. Unscrew the movement screws and remove them from the movement. Pull the crown out to the set position and lift out the movement, holding it between a piece of watch paper.
A4b. To replace the movement, put the movement into the case by starting the stem in the winding arbor. Keep the dial up and make sure the movement is centered by moving the crown to and fro. hold the case between the thumb and middle finger and use the nail of the left forefinger to hold the movement in place. Use the screw driver to set the screws down tight enough to hold the movement.
Q5. Why should you use tissue when handling watch movements?
A5. I should use tissue when handling a watch movement to avoid getting finger prints on the dial, or movement.
Q6. Why should the movement be placed in a tray and covered?
A6. The movement should be placed in a tray and covered to keep dust off the movement, to avoid losing parts and to avoid damage caused by something falling on the movement.
Q7. How should a case be polished?
A7. The watch case should be polished by placing it in a two sided polishing cloth. Open the cloth like a book to expose the red cloth and rub the watchcase until polished. If the case is very tarnished, breath on it to moisten the case to help the polishing.

Chicago School Of Watchmaking
This is my first entry about my education in watch repairing and watchmaking. This won't be a weekly posting, like the other sections; I will post daily updates of what I have learned, the exercises and practical work in the course and answers to the test questions throughout each chapter.
As far as I know, the course has become public domain, so I do not believe I will be breaking any copyright laws. However, I will not be posting the course in it's entirety, or posting scans of the course pages. Only what I have learned that day.
I will also be including pictures and hopefully video posts of the hands-on work. I hope that this feature will be a record that students will be able to follow and learn from. As I learn, so will you. And more importantly, my mistakes will be on display as well.
I don't believe in "learning" from my mistakes. When you learn from a mistake, all you're doing is leaning how to make the same mistake over again, but more efficiently. When I make a mistake, I move on and do a thing again. I know that sounds like the same thing, but it's not in that, I do not analyze mistakes, I analyze success. Do a thing wrong; move on. Do a thing right, examine it and remember the actions, or steps that arrived at the correct result and then move on.
If you would like to follow along, or get a copy of the course for your own study, you can check out a copy from the NAWCC Library, (members only,) buy a copy from Larry Foord, or possibly find a copy either on disk, or hard copy on Ebay.

I'll be flying along pretty fast over the next few days, simply because I've already studied the first three chapters of the course. Starting next week, I will begin the daily postings.
As far as I know, the course has become public domain, so I do not believe I will be breaking any copyright laws. However, I will not be posting the course in it's entirety, or posting scans of the course pages. Only what I have learned that day.
