Avoiding The Pitfalls
Pocket watches are both delicate and durable at the same time, easily broken and yet built with quality materials to run for decades, and designed with maintenance and repair in mind.
Most collectors want the pieces in their collection as close to factory-original as possible, so here are a few of the more obvious issues to avoid when considering purchasing a watch.
At First Glance
Damaged Dials
Once a fragile porcelain dial is broken or cracked it cannot be reversed, and correct replacements take time to locate.
Mismatched Hands
Incorrect or missing hands are an obvious problem because they can be difficult to find and expensive to replace.
Visible Dents
Dents are always caused by an impact. The metal is now stretched, and the internal components have likely suffered too.
On The Outside
Bent Pendants
A bent or leaning pendant is the result of an impact, which likely means a broken balance staff. Bent pendants are also difficult to wind because the stem is binding in the arbor.
Blown Hinges
Hunter cases have delicate hinges and it doesn't take much to force the covers past 90 degrees. Once the metal of the frame is distorted it cannot be made right again.
Misaligned Patterns
Patterns that don't line up with the pendant can be caused by a manufacturing defect or the back is from a different case, resulting in mismatched serial numbers.
Worn Crowns
Crowns wore out from constant use and case manufacturers made many different models and sizes, so finding an original new-old stock replacement is not easy.
Missing Bezels
The bezel is the thin ring that holds the crystal, and is specific to that brand of case. Finding an exact replacement can be nearly impossible - and you still need a crystal.
Incorrect Bows
Chains wore the bow out quickly, so yours could be unoriginal or the wrong style. Aftermarket replacements are available, but the color-match is seldom accurate.
On The Inside
Unoriginal Jewels
Replacement balance or plate jewels are the single most common indicator of damage.
Molested Weights
Ruined balance weights mean the factory poise is lost, affecting positional accuracy.
Distorted Hairsprings
A hairspring is paired to the balance wheel, so replacing it means re-timing the watch.
Mismatched Screws
Incorrect or mismatched screws usually mean that the original threads are stripped.
Broken Parts
Broken or missing parts are a sign of sloppy work and are sometimes difficult to replace.
Ghost Marks
Ghost marks mean that the case has held previous movements and is not the original.
Frankenwatches
Authenticity
Parts inevitably get worn out, lost or broken over the years, which must be replaced from new-old stock or culled from donor movements. This is standard practice with small parts like screws and jewels, but the larger pieces, such as the upper and lower plates, balance wheel, balance cock and others, are all factory-inscribed with matching serial numbers. A Frankenwatch is one that is cobbled together using any part with a serial number that came from a different watch.
Originality
Watches with matching serial numbers are far more desirable from a collecting standpoint, especially early or rare examples worth thousands of dollars. To some extent this is also true of watches that are in their original cases, and the value can climb when provenance is involved, such as a factory shipping box or bill of sale. In May of 2018 our friends at Jones - Horan Auctions sold Rockford SN #1 - an original combination - for $91,000. Click HERE to see it happen.
Avoid greedy sellers who gleefully part out original combinations for a few bucks, knowing that there are plenty of novice collectors who will chase their bits and pieces.
Key Winds
Vintage
Key winds are several decades older than railroad-era pocket watches, which means that they've had several more decades of repairs, and were sometimes run for far too long between cleanings. There was a transitional period in the 1880s when some models were equipped with both key and stem winding mechanisms, but by the turn of the century the key had become obsolete.
Quality
Nearly all key winds are low-grade pieces with fewer than 15 jewels and were not designed to run forever, so anticipate worn bushings and wheel pivots. Mismatched hands and missing screws are common, and since most had only a single case screw they are usually loose inside the case.
Accuracy
The oldest key winds had solid balance wheels, which couldn't compensate for changes in temperature, and they had no weights, so there was no simple way of correcting for poise issues. The flat hairsprings had no overcoil and were mounted in an inaccessible spot underneath the balance wheel, and because of these reasons they were not the most accurate timekeepers.
Condition
It's difficult to find examples that aren't ruined, especially hunters with their broken lift springs, reamed-out key arbors and worn front cover latches. The movements usually have stripped screws, cracked jewels, mismatched serial numbers, distorted hairsprings, missing alignment pins, loose canon pinions, and quite a few other problems. The taper pins holding the dial were easily lost and replaced with anything handy, which enlarged the dial feet until they split.
