Craig Duling, an antiquarian horologist, is a former engineer that currently serves as the CEO of Heritage Management Services. Craig Duling also owns and operates Heritagepocketwatch.com, where he applied his expertise in the evaluation of antique timepieces.
When evaluating pocket watches, it is important to assess the quality of the movement as well as the condition of the dial and case. Jewels are an important watch component that help to reduce friction at movement pressure points and ensure the watch operates correctly over a long period of time.
Pocket watch jewels come in several forms, including round shaped hole and cap jewels, angled pallet jewels, and pin style impulse jewels. Jewels can be set with friction, where they are pressed into a tight hole that keeps them secured. Watches with friction set jewels are typically less expensive and lower quality. Another method to set jewels includes the use of small screws which attach to the movement plate. Screw set jewels can be flush with the plate or a raised style where the setting’s rim is slightly elevated. Watches with screw set jewels are often higher quality pieces.
Craig Duling’s love for rare antique pocket watches inspired him to create a website to share his knowledge. At HeritagePocketWatch.com, fellow collectors and interested readers can find out the history of pocket watches and accessories of all types. Craig Duling provides extensive information on luxury brands such as Rolex, Patek Philippe, and the less-well-known, but equally stunning Vacheron Constantin.
In 1755, Jean-Marc Vacheron signed-on his first apprentice in his Geneva, Switzerland, watchmaking workshop, and a legendary company was born. That year also marked the manufacture of the earliest known of Vacheron’s extant works, a silver pocket watch.
Jean-Marc’s son Abraham continued in his father’s trade. Abraham Vacheron married the daughter of another watchmaker, and eventually went into business with his father-in-law as A. Vacheron Girod.
Jean-Marc’s grandson Jacques Barthélémi Vacheron took over in 1810 and expanded the family business considerably. Under Jacques Barthélémi’s leadership, the company began to acquire clients from Europe’s royal houses and to produce even more complex mechanical marvels, including musical timepieces. It was Jacques Barthélémi who concluded the partnership with entrepreneur François Constantin.
Vacheron Constantin has produced masterpieces such as an 1824 watch whose case shows a map of Italy done in enamel of varying shades of light and dark blue, with yellow gold traceries. The company is additionally renowned for its production of pocket chronometers, such as a fine precision piece manufactured in 1869, during the time of major European explorations of the world. The brand remains an icon today.
Craig Duling serves as CEO of the San Francisco company Heritage Management Services, Inc., and devotes time to philanthropic endeavors. In addition, Craig Duling has studied and collected antique pocket watches for four decades. He shares his love of pocket watches and their history on his website HeritagePocketWatch.com, where readers will find advice on collecting and appraising watches, as well as articles on their history.
With Smithsonian magazine calling the pocket watch the “first wearable tech game changer” in the world, the importance of the pocket watch to human civilization is readily apparent. The precise origins of the pocket watch may be lost in history, although medieval people were familiar with mechanical clockworks. Renaissance-era portraits show men holding watches of various types suspended from ribbons or chains, in an era where simple mainspring technology flourished.
Some authorities believe the pocket watch was invented by Italian makers in the 15th century. Many others point to Peter Henlein, the Nuremberg watchmaker and creator of a single-hand device early in the 16th century. In any case, both men and women were using portable watches in the 1500s. The earliest models were egg-shaped and bulky, but they were soon replaced by flatter case shapes.
King Charles II of England is said to have popularized the securing of pocket watches by chains. When he introduced the wearing of waistcoats in the late 17th century, he provided men with a fashionable way to carry their pocket watches.
In addition to leading Heritage Management Services, Inc., as CEO, Craig Duling focuses much of his efforts in the philanthropic sphere. Also an antique pocket watch collector in his leisure time, Craig Duling maintains the Heritage Pocket Watch site to share his love of classic timepieces. One piece his website highlights is the contemporary Patek Philippe men’s Sky Moon Tourbillon Model 5002P, which features a star chart and is valued at nearly $1.5 million.
The story of Patek Philippe tradition of astronomical complications begins with The Packard grand complication, which was created in 1927 at the behest of James Ward Packard, the maker of the Packard automobile. The watch comprised 10 complications, including a moon phase display, as well as sunrise and sunset times and a celestial chart calibrated to the location of Packard’s mansion in Ohio.
In 1933, Patek Philippe created the Henry Graves supercomplication for one of America’s preeminent bankers. Featuring two dozen complications, the piece still stands as the most complicated pocket watch in history. Among its complications were a Westminster chime minute repeater, a perpetual calendar, and a celestial night sky chart set to Graves’ New York City residence.
Today, the Sky Moon Tourbillon represents Patek Philippe’s most complex wristwatch and features between its two dials a dozen complications, such as retrograde date and perpetual calendar. In addition to its star chart, the watch has an elliptical sky vault that shows the real-time orientation of the visible celestial sky.
Pocket watch collector Craig Duling is the expert behind http://www.heritagepocketwatch.com. Craig Duling’s website showcases his collection of rare and ornate watches and provides a wealth of information about the history and inner workings of various timepieces.
Timepieces that are based on pendulums or springs require winding to help them keep time. Winding is a form of stored energy, which gradually depletes through friction, air resistance, and other forces.
Quartz watches use a battery in place of a winding mechanism. A battery can store enough energy to run a timepiece well for years. In a quartz clock, the battery delivers energy to a small crystal. This crystal will always vibrate at a specific frequency: 32,768 times per second. An electronic circuit in the timepiece is able to count these vibrations, which allows it to generate a small electric pulse exactly once a second.
These repetitive electronic pulses keep time just like the escapements in a mechanical timepiece. They can be used to turn gears that move timepiece arms, or they can be used to power a small display in a digital timepiece.

An avid watch collector in Atherton, California, Craig Duling runs the Heritagepocketwatch.com website. Through this online portal, Craig Duling provides his audience with information about some of the world’s rarest and most valuable watches.
The art of watch making has produced stunning timepieces that have attracted the eye of collectors across the globe. Some of the most impressive of these watches have sold for more than $1 million at prestigious auctions, making them the most expensive of their kind. Here are a few of the watches that have the highest net worth:
Vacheron Tour de l’Ile
Vacheron has been making watches for more than 250 years, the longest of any manufacturer. One of its most valuable pieces is the Tour de l’Ile, a watch that has two faces and numerous complications. Each of these features has contributed to its value of more than $1.2 million.
Patek Philippe Caliber 89
Worth $5.1 million, the Caliber 89 remains the single most complicated watch, with more than 30 complications. Even more impressively, the watch contains over 1,700 different components that combine to weigh in excess of two pounds. Patek Philippe staff spent a total of nine years researching and creating this unique timepiece.
Patek Philippe Supercomplication
Created on commission from Henry Graves Jr. in 1927, the Supercomplication was specifically designed to be the most complicated timepiece on Earth. The resulting pocket watch boasted 24 total complications, a golden frame, and two distinct faces. Eventually, the Supercomplication sold for $11 million in a Sotheby’s auction.
Challenges are never ending as you attempt to achieve goals of nourishing, developing and enhancing passions. My visions to empower children, families and the local communities comes to fruition when observing them surrounded with nature and animals. Especially, the horses taking residence at the Equine Rescue Center (ERC).
Throughout my journeys, I have met and fundraised alongside many charitable organizations. None have showcased second chances or personal dedication the way Monica Hardeman and her rescue ERC organization have. For some time now I have been aiding the ERC to develop a workable business plan as they are struggling to meet the rising costs of their sanctuary. Preserving the property forever as a horse sanctuary is the goal.
Though struggling, they are still able to provide these creatures with exceptional care. The long drought and soaring costs of hay have led to a glut of unwanted and neglected horses and others bound to Mexico for slaughter. The lucky ones end up at the ERC, which is now caring for 85 horses. The property’s current water resources could save the ERC if they can raise the money to put in a portable irrigation system. That would allow the center to grow its own forage and drastically reduce the hay bill.
It’s been over a year since ABC Channel 7 News viewers stepped in to help facilitate the rescue of more than 30 starving and abused horses. The sickest of those horses were taken in by the ERC because other rescue organizations were not up for the challenge. With my own eyes, I have seen the amazing recovery of these beautiful animals and have also had the privilege of being featured in a follow-up story on those same horses’ progress. The story also touched on the how the ERC struggles to keep its bills paid. A story I want to continue to share.
History of pocket watches started in early late 1400s and early 1500s when mechanical engineering reached the state when simple spring devices could be made. By using the invention of mainspring, German inventor Peter Henlein was finally able to create watches that did not require falling weights as the source of their power. This invention gave birth to the first wave of small portable watches, which were in the beginning worn as a pendant on a chain around the neck.
Bu 1524 Peter Henlein produced pocket watches regularly, enabling his innovative designs to spread across Europe during the reminder of 16th century. Early models of mainspring powered watches were round (often egg-shaped) and bulky, but the introduction of screws in 1550s enabled them to gain modern flatten shape that we know today. Another distinctive feature of those early designs was the lack of glass – the only protection from the outside influences was bras lid.
1675 was the year when new fashion style emerged – pocket clocks that were small enough to be wore in pocket and not like a pendant. The originator of this fashion style was Charles II of England who popularized this new way of carrying watches across entire Europe and North America. By then, Glass protection was introduced, and pocket watches truly became the luxurious items that received many attention from fashion designers and innovators. The only downside of the watches that were made before 1750s was their lack of accuracy – they often loose several hours during one day! Introduction of lever escapement changed all that, enabling watches to loose minute or two during one day. This was improvement finally enabled introduction of minute handle which was not present in previous models.
After 1820, levers became standard in manufacturing all clock mechanics (which has not change even until today) and 1857 was the year in which we saw first pocket watch created from standardized parts. Powered with an industrial revolution, such watches soon overflowed the public of Europe and Americas, enabling everyone to buy cheap, durable and accurate watch. By 1865 American Watch Company could manufacture more than 50 thousand reliable watches, and soon after that other companies joined them in the manufacturing effort.
Between 1880 and 1900 saw the first attempts of standardizing time, not only for creation of time zones but also because of ever increasing need of precise time measurements in many scientific experiments and public transportation systems (famous Ohio train wreck of 1891 happened because of train engineer watches were 4 minutes out of sync).
By the time of World War I, pocket watches went out of fashion after highly miniaturized wrist watches became famous.
