A Note of
Appreciation
Paul Corn received this note from
an HT reader.
Dear Sir,
Just a note of appreciation
and thanks for your article on
repairing music box governors
in Horological Times, January
2016. It is so nice to see an
article relevant to a member’s
real work instead of all the
exotic higher-grade horological
articles. I have repaired cuckoo
clocks for 35+ years and always
enjoy learning from another
approach. I have a pile of used
governors which I often take a
gear off of but replace with new
whenever possible. However,
your tip with the plastic gears
was good.
Sincerely,
Robert Mohr
Lifetime member of AWCI
The Hamilton Poster
I really like the Hamilton poster.
It is just the right size. I placed
it under the clear plastic mat
where I take in watches and
clocks, and I get a lot of positive
comments on it, especially from
collectors.
Bob Little, CC, CW
Editor’s Note: If you’d like to order the
Hamilton poster to put in your workshop, go to

Praise for San Diego Polishing Class
Dear Mr. Jordan Ficklin and Tom Schomaker:
When Mr. Russell Tilghman told me I'd benefit from taking a polishing class I thought to myself,
"I've been polishing for almost 30 years with satisfactory results. What is there to learn about
polishing?"
It turns out quite a bit, not just about the superiority of today's compounds formulation, but about
new techniques utilized where one can achieve near flawless results, more in line with factory
specifications. After this class my level of self-confidence has improved tenfold.
I'd like to thank all of you for making it possible to have technical training in San Diego, and
I truly wish, Tom, that training could have been extended/expanded to cover subjects such as
watch hands refinishing and removing blemishes on dials, or even other topics, such as movement
finishing.
Time
is
Money
On this subject, the general consensus of all
the participants was that should hands/dial
training be taught in San Diego everyone
would attend. Any dates available... 
The venue was top notch with easy access,
plenty of parking, and great restaurants within
walking distance, right across the street from
one of many San Diego harbors.
Thank you again, and God preserve Tom's
elephant memory and his ability to engage the
class in such an easy and friendly way.
Hope to see you back soon!
Knowing how to properly repair watches and clocks
saves time—while also generating additional traffic and
profits. It also helps to protect and enhance the brands
you promote as well as your reputation and integrity.
Expertise through formal training is available through
AWCI, and demand is growing! We invite you to learn
more about the CW21 and CC21 certification programs.

Feature: Timing Machines and How They Work
Timing Machines and How They Work
W
atches and clocks were timed for hundreds
of years without the benefit of timing machines, so why do we now need a timing
machine? Once I cover why timing machines are
needed, I will discuss how they work.
Why Do You Need a Timing Machine?
When you receive a timepiece for service you may
want to first test it to look for any issues. If it is running, maybe the customer just wants it adjusted.
Without a timing machine, it would take hours or
days to determine if it is running correctly. If the
timepiece needs service, then once it is cleaned and
reassembled it will need to be adjusted and tested.
With a pocket watch, this can be done without a timing machine by hanging the pocket watch on a peg
and checking it against a known watch or clock and
adjusting the regulator until it performs acceptably.
Today it is costly to have an extended evaluation
period, and customers are looking for a reasonable
turnaround time on the servicing. This peg testing
did more than just indicate whether the watch kept
By Dale Sutton
time. It also provided evidence as to whether the
watch was in beat. If the watch was out of beat, it
would begin to swing back and forth over time. The
greater the swing, the more out of beat the watch
was. A timing machine provides a fast way of determining the rate and beat of a timepiece. The test can
be done in a few minutes to make a measurement,
and a watch can be turned in all six positions to look
for other errors. The timing machine also provides
indication of train errors such as magnetism, loose
pallet jewels, and escape-wheel problems.
Everyone doing mechanical timepiece servicing
should have a timing machine. All watch manufactures require timing machines for certification. These
machines must also provide for amplitude measurement. I will discuss this measurement later.
Even a collector may find having a timing machine
is a great advantage. Collecting antique watches is
my hobby. Once I had a timing machine, I was able
to see that several of my purchases had issues that
needed attention even though they were marked “in
good running order” and seemed to keep okay time.

Daniel Benson is a graduate of watchmaking at George Brown College,
Toronto, and a first-place graduate of WOSTEP in Neuchâtel, Switzerland.
As well as a career in horology, Daniel has worked extensively in book
publishing and communications.
"Old-Time Resources" is designed to introduce new watchmakers and clockmakers to printed resources that have been around for
a long time but which newcomers to the field may not be aware of. The seasoned professional may also find value in these old-time
resources because they may have forgotten they exist, or they may never have been exposed to them.

Technical Discussion: Overhauling the Urgos #32 Movement
OVERHAULING THE
URGOS #32 MOVEMENT
T
he Urgos #32 movement, used mostly in grandmother clocks, has been a reliable movement
for years. There are two movement styles.
Old-style movements are identified by the flat
chime lever tension spring, Figure 1, and the pin that
holds the chime levers together, Figure 2. New-style
movements are identified by the coiled spring that
is formed around the chime lever and the lifter lever,
Figure 3, and the screw that holds the chime levers
together, Figure 4.
After servicing and rebuilding these movements
for several years, I have found three faults with them
after they have been out in the field for some time.
They will over-strike the hour, wear to the point that
the chiming levers won’t lift high enough to unlock
the sequencer, and the rear center shaft pivot hole
will wear excessively.

DARPA Calls for More
Accurate Independent Timekeepers
By Aaron Recksiek, CW21
In
our modern world, much of how we communicate and navigate is dependent upon
perfectly accurate timekeeping, accurate
to the atomic level. So far, much of this is done by
synchronization and calibration with a reference signal received by GPS, radio frequency, or cell towers.
Even in the clock and watch industry, more and more
timepieces are produced each year that receive synchronization with a master clock, especially with the
growth and popularity of smartwatches.
The Defense Advanced Research Projects Agency (DARPA), a division of the United States Department of Defense, is looking for more accurate and
stable independent timekeeping devices. There has
already been a lot of research and development
of Chip-Scale Atomic Clocks (CSAC) since their
first introduction in 2004. The current standard of
timekeeping in a CSAC is +/- .00000000001 second in a stable, controlled environment. Over the
last 10 years, however, there have been constant

Martenero
A young New York
City-based watch brand
offers customers highly
customizable watches
By Donna Hardy
J
John Tarantino, founder and CEO of Martenero, was part of the American Showcase at AWCI's 2015 convention.
ohn Tarantino is the founder and CEO of Martenero, an American watch company based in
New York City. Martenero’s watches are noteworthy in part because they are highly customizable
with various straps, dials, and hands that customers
can choose from to craft a unique watch. It’s easy
for customers to customize their own watch on the
Martenero website (www.martenero.com), and then
the watch is assembled and sent to the customer.
The watches are sporty looking, but a dressier
model is also available. The watches cost between
$485 and $595. Martenero offers five different models—Founder, Marquis, Ace, Limited Edition Ace, and
Ascent—and all are customizable. Inside the new
collection (the Ascent and the Marquis) is the Miyoto
9015 movement. The original collection (the Ace and
the Founder) uses the Miyota 821A movement. Tarantino is not focused on large-scale manufacturing
yet, but he hopes that will develop in the next 5 to
10 years.

Tarantino was part of the “American Showcase”
at AWCI’s convention in Kansas City last year. He
was showcasing his watches (Martenero had just
released two new models—the Ace and the Marquis),
but he mainly came to the convention to connect
with industry. One of the benefits of attending
AWCI’s convention was to meet watchmaking students whom he might hire in the future. I had the
opportunity to talk to John Tarantino and ask him
about his business.
Aside from the fact that you collect
watches, why did you decide to start
making them?
I got into watches seven or eight years ago, and was
always focused on mechanical pieces rather than
quartz. I first got interested in watches because of
aesthetics. I just thought they looked nice. From there,
I became much more interested in them as I learned

BASELWORLD AGAIN
B
aselworld opens once again this year on March
17, which means the Americans visiting there
will be celebrating St. Patrick’s Day drinking
Swiss beer instead of Guinness and eating bratwurst
rather than corned beef. Tough duty but someone
has to do it. As has become customary, I will be
there for opening day to see what is new for 2016 in
the world of watches with a focus on our specialty—
watchmaking.
In addition to dusting off the passport, airline
tickets need to be purchased (well in advance), hotel
reservations must be made (again, well in advance),
and a rental car needs to be reserved. The rental
car arrangements are far more favorable if made in
advance from the US rather than walking up to the
counter at the Swiss airport without a reservation.
An excellent transportation option for someone
who does not want to drive while visiting Switzerland
is to buy a Swiss Travel Pass here in the US before
departing for Switzerland. Public transportation
in Switzerland is unrivaled anywhere in the world.
The unbeatable combination of trams, busses, and
railroad trains will bring a traveler to just about anywhere in Switzerland, and do it very efficiently. The
rental car option makes sense for me as I travel with
a companion to share the expense, and we keep a
very tight schedule to accomplish as much as possible during our stay.
While in Switzerland, I will visit vendors who do
not exhibit at Basel but will welcome guests at their
office. All of those extra visits need to be arranged in
advance. Impromptu visits to a supplier’s office are
not really encouraged at any time and less so during
the Basel Fair week, when they welcome many clients
from all over the world to their offices. If possible, this
year I will stay a few extra days to study at a factory
repair facility that specializes in mechanical watch
repair. I am looking forward to the trip and will be
reporting back to you upon my return.
“IF THERE BE NONE, NEVER MIND IT”
Early in my watchmaking career, I tried to meet as
many practicing watchmakers in the Boston area
as possible to learn more about my newly chosen
profession. I clearly remember Mr. Jenkins who had
a very tiny shop on the second floor of his home
with a small sign on the front of his house. His sign
was small and simple in that it stated his name and
that he repaired watches. I guess crime was not such
a concern at that time, even in a city very close to
Boston.

By Jack Kurdzionak, CW21, FAWCI
During a visit, I told him I was interested in repairing old American pocket watches, and I still
remember his advice to this day. He said to stay
away from E. Howard watches because spare parts
were hard to find, and I should focus upon repairing Waltham and Hamilton watches. What I came
to learn was that Howard watch parts were mostly
available but just not as plentiful as the other brands.
In those days, the early 1970s, spare parts did not
seem to present any problems. All I had to do was
visit the three buildings in the jewelry district, and
one of Boston’s 10 material houses would invariably
have any part I could possibly need. If they did not
stock the part, they could order it and have it within
a few days. If I needed a hairspring vibrated, a dial
refinished, or a hunting case lift spring made, it was
no problem. Every material house had sources that
could provide those services. I began my watchmaking career without being overly concerned about
sourcing spare parts. As time passed, the number of
Boston material houses slowly dwindled from 10 to
one. In Boston and throughout the country, material
houses gradually disappeared, as did the dial refinishers, while companies furnishing case repair and
hairspring vibrating entirely disappeared. Further
compounding the problem, while the traditional
suppliers of spare parts went out of business, many
watch companies gradually began limiting the sale
of spare parts to selected accounts and retailers of
their respective brands. This new year does not hold
any promise for easier access to spare parts. It only
promises to present greater challenges for watchmakers to overcome. In addition to concentrating on
solving repair problems, the watchmaker needs to
be certain that any needed spare parts will be available for each repair.
In the past, most of the time I could make a quick
inspection of a watch needing repair with the knowledge that any needed spare parts would be readily
available. For almost every repair, including those
E. Howard watches, I could obtain exactly what I
needed in Boston. The only concern for watchmakers
at that time was a small price increase. I remember
Irving Cohen, of A. Cohen Co. in Boston, who would
caution me whenever there was a price increase by
saying something like, “Jack, those Waltham pocket
watch mainsprings have gone up in price from $0.75
to $1.00 each. Are you sure you still want six of
them?” My answer then, as it would be today, was:
“Yes, unless I can make the watch run without a
good mainspring.” We still need parts to repair the

Column: Q & A with David Christianson
named after its inventor, Jean Antoine Lepine (17201814), a prominent French watchmaker.
The late Adolph Chapiro of Gif-sur-Yvette,
France, classified the various generations of Lepinestyle movements into six calibers, starting with the
Original Calibre used by Lepine himself between
1765 and 1795 and by other makers until 1815.
Your movement would be classified as a Calibre
V, a movement used from about 1850 until the
introduction of stem winding in ordinary watches
around 1872.
The ebauches, or rough movements, from
which yours came, were supplied to various watch
finishers or watchmakers by specialized ebauche
factories in France and in Switzerland, the largest
of which was the Japy factory near Besançon.
Japy adopted the Lepine calibers for his and the
world’s first machine production of watches.
The dust cover suggests that your watch was
made by TH French in London. There were several
makers named Thomas or T. French in England
and Wales during the 18th and 19th centuries, but
none are listed as having been in London. Given
the Swiss penchant at the time for using wellknown and/or familiar names and locations on
their watches, I would say that your watch was
made by an unknown finisher in Switzerland in the
mid-19th century using a familiar maker’s name on
the inside cover to make the buyer think that he
was getting a quality watch made by a well-known
Swiss watchmaker.
