Pocket Watch Storage, Winding & Care
An antique pocket watch that has survived a century or more deserves proper care to survive another century. The good news is that mechanical pocket watches are robust instruments — they were designed to be carried daily in a working man's pocket — and they need no complex maintenance between services. But storage conditions, winding habits, and a few simple precautions make the difference between a collection that runs well and looks good for decades, and one that silently deteriorates on the shelf.
The Fundamentals of Good Storage
Temperature
Store watches at room temperature — 15–22°C is ideal. Avoid attics (summer heat), garages (winter cold), and anywhere subject to significant temperature swings. Rapid temperature changes stress mainsprings and hairsprings.
Humidity
The target is 40–55% relative humidity. Too dry and rubber gaskets (where fitted) crack; too damp and steel parts rust and brass tarnishes. A small silica gel sachet in a storage box helps stabilise humidity.
Light
Keep watches out of direct sunlight. UV degrades enamel dials over time, fading the glaze and yellowing white dials. Display cases with UV-filtering glass or acrylic are worth the investment for a permanent display.
Magnetism
Keep watches away from speakers, motors, magnetic clasps on bags, and MRI equipment. A magnetised hairspring causes wildly erratic timekeeping — gaining or losing many minutes per day. Demagnetisation is simple but prevention is better.
Dust
Dust is the enemy of any open-back display. It settles on movement surfaces and wicks oil from pivots. Watches stored open-back for display should be enclosed behind glass. Keep stored watches in cases or boxes.
Position
Store watches dial-up or on their side — not crown-down, which puts lateral stress on the winding stem. Watches that will be unwound for long storage should be left dial-up.
Winding — Getting It Right
Winding a pocket watch correctly is not difficult, but a few habits protect the watch from the most common cause of mechanical damage.
How Often to Wind
Most pocket watches have a running time of approximately 36 hours from a full wind. The best practice for a watch in regular use is to wind it at the same time each day — morning is traditional, before the watch goes into the pocket. Daily winding keeps the mainspring operating in the middle of its power range, where it delivers the most consistent power to the train and runs the most accurately.
Never wind a watch in the pocket or against clothing — the risk of dropping it is too great. Hold it in the palm, case back down, and wind with smooth, even turns of the crown.
How to Wind
Turn the crown (the winding knob at the top of the case) clockwise. You will feel and hear the ratchet click with each partial turn. Stop as soon as you feel the resistance increase — when the mainspring is fully wound, attempting to force it further stresses the spring, the click, and the ratchet wheel. Do not try to get "one more click" past the natural resistance. A correctly wound mainspring will feel solid and resist further winding clearly; a broken mainspring will feel loose and offer no resistance at all.
Key-Wind Watches
Earlier pocket watches — those made before the keyless-wind mechanism became standard in the 1870s — are wound with a separate key inserted through the back of the case or through the dial. The key must fit the square winding arbor exactly; an ill-fitting key will round the corners of the arbor square and make future winding difficult. Keep the correct key with each watch, ideally attached to its case or stored in the same box. Winding is clockwise for most key-wind watches.
Watches in Long-Term Storage
If you are storing a watch that will not be used for several months or more, it is generally better to let the mainspring run fully down before storage. A fully wound mainspring under constant tension over a long period can take a permanent set — a slight kink or deformation that affects its power delivery. Running the watch down before storing avoids this stress.
Set the hands carefully. When setting the time, always move the hands forward (clockwise) — never backwards. Many antique pocket watches do not have a mechanism designed to drive the calendar or complications backwards, and forcing hands in reverse can damage the setting mechanism, the cannon pinion, or the hands themselves. If you overshoot the correct time, continue forward around the dial rather than reversing.
Display Options for a Collection
Displaying pocket watches well is as much a matter of care as of aesthetics. The best display options protect the watches while showing them off effectively.
| Display Method | Pros | Cons / Watch Out For |
|---|---|---|
| Velvet-lined display case | Keeps watches together; looks professional; protects from dust when glazed; watches visible without handling | Velvet can attract dust; ensure glass or acrylic lid. Avoid unglazed cases — they are dust traps. See Display Cases. |
| Individual watch rolls / pouches | Excellent protection; soft lining prevents scratching; stackable; ideal for transport | Watches not visible without unwrapping; humidity can be trapped inside synthetic-lined rolls |
| Watch stand / pocket watch holder | Shows individual watches at their best; ideal for bedside or desk display; easy to pick up and use | No dust protection; only suits 1–3 watches at a time; keep away from direct sunlight |
| Original boxes | Historically appropriate; adds to value if original to the watch; excellent protection | Old cardboard boxes can off-gas acids that tarnish metal; line with acid-free tissue if concerned |
| Coin capsules | Inexpensive; airtight; available in correct sizes for most pocket watches; stackable | Not decorative; some collectors feel they look too clinical; check the capsule fits without forcing |
Do and Don't
✓ Do
- Wind at the same time each day
- Set hands forward only
- Store at stable room temperature
- Use silica gel in enclosed storage
- Handle by the case, not the bow
- Clean case exteriors with a soft dry cloth
- Keep keys with key-wind watches
- Have movements serviced every 5–10 years
- Record purchase details and serial numbers
✗ Don't
- Force the crown past full wind
- Set hands backwards
- Store near magnets or speakers
- Leave in direct sunlight
- Store in a damp basement or hot attic
- Use metal polish on dials
- Oil movements yourself — wrong lubricants cause damage
- Force a stiff crown — get it serviced first
- Store fully wound for months at a time
Insurance and Record-Keeping
A collection of antique pocket watches represents a significant investment and should be covered by insurance. Many home contents policies do not automatically cover valuable collections; a specialist art and antiques rider or a dedicated collectibles policy is advisable. For insurance purposes you will need a description, photographs, and ideally an appraisal for each significant piece.
Keep a simple record for each watch: the serial number, maker, grade, case material, purchase date and price, and the date of the last service. A photograph of the dial, case back, and movement is invaluable for insurance claims and is useful if a watch is ever stolen. See Pocket Watch Insurance for more on coverage options, and Getting an Appraisal for how to establish values for insurance purposes.
When to Have a Watch Serviced
A mechanical pocket watch should be serviced — cleaned, lubricated, and regulated — approximately every five to ten years in regular use, or every ten to fifteen years in storage. A watch that is running significantly fast or slow, stopping before its power reserve is exhausted, making unusual noises, or that has not been serviced within living memory should be examined by a qualified watchmaker before further use.
