A Brief Glossary of Technical Terms (continued)

UP-AND-DOWN INDICATOR

An additional hand that shows how far a watch is wound up, usually working on a subsidiary dial placed below the 12
o'clock position.

UNITED STATES

The beginnings of watchmaking in the United States were hampered by a want of metallurgical skills and raw materials;
watches could scarcely be made out of wood, as were some of the earliest American clocks.   Many early ‘watchmakers’
imported movements from England.   By 1859, however, the American Watch Company (afterwards Waltham), with
Aaron Dennison as technical supervisor, was producing watches of a type already distinctive (based on Liverpool
full-plates but without fusees), using efficient machine-based methods inspired partly by Swiss models and partly by
recent innovations in American small-arms manufacture.   Several more substantial manufacturers, such as Elgin,
Adams & Perry (afterwards Hamilton), E. Howard, the Illinois and New York companies, and Cornell in far-off San
Francisco, opened their factories between 1858 and 1875.   By 1900 the stringent and specific demands of the great
railway companies were shaping the nature of the railroad watch, and the largest firms were producing hundreds of
thousands of watches annually.




American watch design tended to be advanced but not innovative;  few new or unfamiliar devices appeared (the cheap
Waterbury company's astonishing flirtation with the duplex escapement in the 1880s is an exception), but it was
America which transplanted such things as overcoil hairsprings, compensated balances and the general jewelling of
train wheels from the realm of the exotic to that of the commonplace.   In appearance, watches of 18 size or larger (see
American gauge) were often full-plates until after 1900, while smaller calibres adopted a compromise barred design with
each bridge locating several wheels instead of only one — a pattern which became almost universal in the wrist-watch
age.   Typical of the U.S.A. is the use of grade-names;  in addition to or instead of the manufacturer, a watch might be
marked with the name of a company director or supporter (Waltham's ‘P. S. Bartlett’, Elgin's ‘B. W. Raymond’), a
descriptive or patriotic phrase (‘Ladies' Stem Wind’, ‘Native Son’) or the name of a historical character (New York's ‘John
Hancock’, Hampden's ‘Molly Stark’).   A single model (for the U. S. manufacturers also adopted model designations)
might come in several different grades each distinguished by an individual name.


VERGE

The oldest and longest-lived of all escapements, invented (probably before 1300) for large wrought-iron church clocks
and successfully applied, almost without change, in 18th-century French watches an inch or less in diameter.   Verge
watches are notoriously inaccurate, tending to run very fast;  Captain Cuttle's watch in Dombey and Son — “Put it back
half an hour every morning, and about another quarter towards the arternoon, and it's a watch that'll do you credit” — is
scarcely an exaggeration.   However, it should be remembered that in this escapement the contact between pallets
(which are never jewelled) and escape-wheel is exceptionally violent and conducive to wear.   See Escapements for more
detail.

VERGE-STAFF

The long arbor running horizontally between the plates of a verge movement, with the crown-wheel at its inner end and an
elongated pinion, engaging with the contrate-wheel, about half-way along its length.   In English and Dutch watches the
bearing at the outer end is a plain brass plug, whereas French and Swiss makers from about 1750 onwards preferred an
arrangement of two brass strips, one fixed and one adjustable by means of two small steel screws whose heads face
outwards;  this often helps to identify a Swiss forgery of an English watch.

VIRGULE

A modification of the cylinder escapement, invented in the 1750s by Jean André Lepaute and refined by Lépine.   The
cylinder is very small and an extended curved flange projects from it on the side where the escape-wheel teeth emerge
from it;  the pressure of a tooth against this flange gives an enhanced impulse, but only on alternate swings of the
balance.   The virgule is virtually confined to France and to the period 1780-1820.

WALTHAM

The first of the great U.S. watchmaking firms, originally set up in 1849-50 by Aaron Dennison in partnership with Edward
Howard and David Davis.   The enterprise survived several reincarnations, including Appleton, Tracy & Co. (1857;  the
name is worth noting because it was revived as a grade-name on much later Waltham watches, so that very few of the
watches so inscribed actually belong to the coveted pre-Civil War period).   The Waltham name iself dates officially from
1885.   The early Waltham watches, with their going barrels, screwed-in movements, jewelled train-wheels and
(increasingly from 1868 onwards) stem-winds, set the style for the entire industry.   The 1883 model, (side-lever and
full-plate
, 18 size) remained in production for 36 years.   Waltham responded effectively to the demand for railroad
watches
but was less successful in meeting the challenge of the Swiss wrist-watch.   The independent company ceased
to exist in 1957.

WATERBURY

U.S. manufacturer based in Waterbury, CT, originally founded as clockmakers in 1843 and connected with the pioneer
American clockmaker Chauncey Jerome (1793-1860).    The Waterbury name dates from 1857 and watchmaking began
twenty years later.   Waterbury specialised in cheap watches (as they still do, under the name ‘Timex’) but made a
surprising technological sortie with their ‘Long Wind’ and duplex series in the 1880s.

WINDING SQUARE

The protruding end of the mainspring arbor, squared off to receive a key, in a key-wound watch.

WINGED COCK

A cock with projections (shaped roughly like oak-leaves or stylised wings) on either side of the circular table at the point
where it joins the foot;  common on English watches from about 1710 to 1750.

ZECH, Jakob

(?-1540)   Bohemian craftsman, maker of the earliest precisely datable portable table clock (effectively a very large
watch).   Made for King Sigismund I of Poland, it is dated 1525 and has a wrought-iron verge movement with fusee, hour
and month hands (but no minute indicator), a disc rotating once a year, and a simple striking mechanism.
