Take a look at this remarkable demonstration of a model of the Antikythera mechanism, the earliest known (150–100 BC) device for calculating the positions of known astrological bodies. It is a mechanical computer of astounding complexity.
Seeks Rare Clock Part
Elgin, Ill. - A search among collectors' clubs throughout the nation for the missing part of a clock so rare that less than a dozen are in use, has been launched by William H. Samelius, director of Elgin Watchmakers College and dean of American horologists.
Samelius seeks a jointed doll, not more than three inches high and seated in a swing. It served originally as the "bobbing pendulum" of a clock produced in 1886 by the Ansonia Clock Company, now of Ansonia, Conn.
He explained that, unlike an ordinary clock, the bobbing pendulum operates in a vertical motion with the weight suspended on a helical spring. It is kept in motion by a regular escapement through a lever connected with the spring, the lever getting its energy from the escape wheel.
In the ordinary clock - says Samelius - the pendulum is suspended with a thin leaf spring and the pendulum is kept in motion by a lever that receives its energy from the escape wheel.
"Since the original equipment was lost I have operated my bobbing clock with a weighted buddha," he said. "Now I have other uses for the buddha and I believe that some collectors' group may put me on the trail of the missing doll."
He will exhibit the clock to the collectors' group of the woman's club of Highland Park, a Chicago suburb, to get underway the hunt for the missing doll.
William Samelius was particularly expert in unusual escapements and owned a large collection of escapement models.
As an aside, the same page on which the above article ran included this interesting note, a sign of those times...
Clock Workers Alert
Boston - The national convention of the Independent American Watch Workers union has adopted a resolution barring "Communists" from holding appointive or elective office in the organization.
The delegates, representing 8,000 watch workers in Waltham, Mass., Elgin, Ill., Lancaster, Pa., Lincoln, Neb., and San Francisco, also sanctioned plans for expansion of the union into the clock and repair field.
Check out this novel clock design combining modern/retro gauges with a classic clock case design. The clock works, using analogue gauges, is available as a kit.
Follow the link for some interesting images of classic examples of 1970s design styles in watches from French watch maker Lip.
I don't know why this this picture of a dog is here though, anymore than anyone else.
Follow the link above for some information on a really spectacular watch, the "Marie-Antoinette", and a forthcoming book. I look forward to learning more about the book. It should be an interesting subject.
Modern Navigation dates from 1762, when John Harrison's Chronometer reached the West Indies, after a voyage of sixty-one days, with an error of only five seconds.
The rich prize which Parliament had offered for half a century - twenty thousand pounds sterling - went to Harrison. His victory, after thirty years of struggle, hinged on his previous invention of the Compensating Pendulum.
Unlike the modern ship's-watch, his timepiece was not suspended in gimbals but carried on a pillow.
The world war set new standards in naval timekeeping. The torpedo boat, with its terrific vibration, baffled America's experts till Elgin railroad watches were adapted to the service, And the first acceptable ship's-watches supplied our navy in quantities sufficient to equip the U. S. Emergency Fleets were - as might have been expected -

"TIME!" One of the shortest words in the Railroad Man's mother tongue - and doubtless the most tremendous.
A race with Time! There you have the Railroad Man's summary of his very life. For Time is his one great objective. His shippers, his travelers place above almost every other consideration the Value of Time.
Speed and safety travel together only when Father Time himself leads the way. For Father Time, on America's railroads, stands for that amazing development of Time-Service and train dispatching which alone make speed and safety possible.
For half a century, too, Father Time has stood for the finest railroad timepieces that money, brains and skill can produce -
Interestingly, this one is in a 20-year gold filled case with a decorative engraving on the back. In those times, watch manufacturers did not typically make cases, so someone bought a nice case for this movement. It's not unusual to see really good watches in cheap cases, and the reverse, as we see here.
Lastly, the watch is marked as adjusted for temperature. This adjustment is of course simply made up.
celluloid caps over normal pivots, non-functional external wheels, and a solid balance with phony "timing screws". It is also marked "heat and cold" which makes no sense what so ever.
At the center wheel, the brass ring meant to look like a jewel bushing is missing, showing that the jewels are just red disks sitting in recesses in the plate. Also, close examination reveals that the heads of the screws that would normally be holding the jewels in place, on this watch do not overlap the jewel bushings at all and so are also serving no purpose except appearance.
Note the jewels. The watch is marked 21 jewels, however the "jewels" are actually just caps over non-jeweled pivots. The "jewel" for the center wheel is missing, making the actual pivot visible. And in fact, the "jewels" are likely to be celluloid. Next, note the balance wheel. It is one piece, not split and not bi-metallic. The timing screws are actually just pins sticking out from the wheel.
The regulator includes a spring that actually doesn't do anything except hold the regulator in one place. It's just there to look nice, and to imitate actual micro regulators.
There is no click on the "ratchet wheel". And in fact the exposed winding wheels are also just for show. The do not move.
It's not unusual for these watches to include non-sensible claims on the movement, misspelled words, fake wheels and other humorous features. Meanwhile, the movements definitely resembled high-end American makes. The cases also often would include a picture of a steam engine, as was at the time a popular way to give a watch an association with quality.
All in all, not exactly a great watch! But it is an interesting piece of history.

In my last note here regarding mainsprings I mentioned an example of a spring that, although unbroken, is so badly set that it is locked fully into the shape of the mainspring barrel. Here is that sample.
Amazingly, this is also a spring for an 18 size Elgin pocketwatch. It is the exact same size and type of mainspring as those pictured in the prior post.
Over time, a couple of years of continuous use perhaps, this compression/expansion cycles cause the mainspring to give up some of it's force of wanting to return to it's original shape. Such a spring is said to be "set." In the most extreme cases , a spring can actually suddenly set into a fully coiled tight state. Although this is rare, some setting is notable in a mainspring even fairly quickly as it is in use. Watches in daily use need a new mainspring on a regular basis.
Shown here is an old spring and a new spring for an 18 size Elgin pocket watch. Note that the new spring turns back on itself at the outside end. This curve compensates for the fact that the force provided by the mainspring varies from when it is fully wound to nearly unwound. This variation can impact timekeeping over the watch's run-time.
The watch is a nice 17 jewel Hamilton. It was brought in Clark's Jewelry (formerly Overjourdes' when my Grandfather owned it) in Coeur d'Alene.
I'm not sure of the best way to present things like this (ordinary web site? Blog? Online document?). There are a lot of choices these days so I may use more than one now and then, to see what works best.
Anyway, to get started, here is some information on watch crystal codes.
Watch crystals are categorized using a cryptic code of letters and numbers the meanings of which may seem completely arbitrary at first. It may surprise some, but there are actually meanings to these codes.
Firstly, the basic shape of the crystal is given by a letter. The following letters are used in one common code system, used for G-S Flexo crystals.
|R||Rectangular with cut corners|
|T||"Tonneau", two straight, parallel sides (short) the other two (long) convex|
|Q||Square with cut corners|
|C||"Cushion", four convex sides|
|D||Diamond or an elongated octagon|
|Q||Square, cut corners|
|V||"Rococco", concave corners|
|Y||Similar to T but with convex short sides instead of long sides|
|Z||Rectangular with concave sides|
|F||"Fancy" - any other shape, generally irregular such as hearts|
These letters (one, two or there) are followed by a number indicating the specific crystal.
Here's a few examples:
MT2005 - A tonneau crystal, not flat but curved, number 2005
MS1975 - A square crystal, curved, number 1975
CMS2050 - A Square crystal, curved, and cylinder
There are a few other labels, types and designators found on watch crystals such as "Durex", which is a extra thick. Also, lines of plastic crystals ("unbreakable") frequently prefix a 'P' to the entire code. Watch-Craft and Rock-Craft are quite common crystals these days, but they use shape codes different from the above.
This is not the only crystal designation system. Many manufacturers used their own systems which were either completely different, or included additional shape codes. This is inconvenient, but to me it is one of the fascinating things about vintage watches. These systems where early attempts at standardizations that we take for granted today. The systems are cryptic because they were created in a time long before computers. At that time, having any system at all was a major selling point for watch companies, watch parts houses and suppliers ("jobbers").
Finding the right crystal for a particular watch can still be a challenge even with this system. But that's another topic...
One of a series of little biographies or Elgin Watches
writes Stuart Hotchkiss, Yale '36
"Land ho... Marsteinen Light dead on!" And Stuart Hotchkiss navigated the schooner "Vagabond" to the finish of the greate Newport-Norway race of 1935.
Twenty-five days on the the Atlantic... 3,600 miles logged... the longest, most hazardous ocean race ever sailed! Here was a record of which his ancestors who captained the fleets of Salem a century ago would have been proud.
Now young Hotchkiss is graduating from Yale. "I'm looking forward to receiving an ELGIN at commencement," he says. "Like the sea and sailing; ELGINS have been a tradition with us for generations."
And no graduate could wish for a finer gift than Elgin! Study the newest models and you will agree.
There is a bracing freshness about them. A sturdy, well-conditioned appearance that invites confidence. And on the technical side, they are perfection itself!
ELGIN is the one place in all the world where master watchmakers join in perfect partnership with modern scientists. Together they plan, create, and completely finish each ELGIN movement under a single roof.
The result is timepieces that incorporate many watchmaking advances... accuracy-checked to the standard of the stars by an electrical timing device, developed in cooperation with ELGIN craftsmen.
Choose an ELGIN for your graduate now. The new models are at your jeweler's. Prices: $17.50 to $500.
