Craig Duling is an expert in rare timepieces who currently applies his knowledge as an antiquarian horologist as the owner of Heritagepocketwatch.com. A former missile and space engineer, Craig Duling has extensive experience in the assessment and evaluation of pocket watches.
The assessment and valuation of pocket watches, particularly vintage models, is extremely complex due to the wide variety of designs, styles, dates of production, and components. Identification, which requires the age and manufacturer to be pinpointed, is often a first step. Quality is also an important factor. The number of jewels, finish quality, and the materials used can be used to grade the quality of a watch.
In addition to the overall quality of the watch, the visual appearance and working condition are also factors that impact value. For example, water damage, cracks, or other damage can impact the internal functions and appearance of a pocket watch. Alternatively, unique features such as an uncommon effacement or diamond accessories, and the rarity of the watch can enhance value.

An entrepreneurial leader, Craig Duling guides Heritage Management Services, Inc., and has contributed extensively to his local community. Away from work, Craig Duling has a passion for antique timepieces and maintains a blog in which he provides information oriented toward investment-grade pocket watch collectors.
Of particular interest to American collectors are railroad pocket watches, which were standard issue for conductors from the 1820s, when railroad travel emerged. Brakemen, enginemen, and yard foremen were also required to carry these pocket watches, for which railroad-grade guidelines were developed in 1893.
The timepiece was of critical importance prior to the invention of the telegraph in the 1840s, as trains often shared a single track in opposite directions, and communication while in transit was not possible. Timetables emerged to ensure that trains did not collide and were kept on the most efficient schedule possible. Unified standards for the watches came into being after a fatal head-on collision in which a faulty watch, which started and stopped, thus losing four minutes, was the culprit.

Craig Duling is a California entrepreneur who serves as CEO of Heritage Management Services, Inc. In terms of hobbies, he has a longstanding interest in collecting antique pocket watches. On his blog site Heritage Pocket Watch, Craig Duling features a wealth of information on vintage and collectible timepieces and archives rare pieces for the sake of historic documentation.
One article on the site explains the non-decorative use of jewels to eliminate friction in watch movements to the maximum extent possible. Smooth and hard, faux rubies used for this purpose are made from ammonia and aluminum, and put through a variety of heat and chemical processes, ultimately resulting in what is known as a boule. The boule then undergoes as many as 50 additional cuts and processes, which ensures that it is as hard and smooth as possible.
These jewels have a variety of cuts and uses, with timepieces of higher quality often featuring a 17 or more of them throughout the watch mechanism. One key advantage they provide is in enabling the mainspring to be designed in as efficient a manner as possible, which boosts the running times.
