If you own a mechanical or automatic watch, how you store it matters almost as much as how you wear it. A watch that spends its downtime in the wrong conditions, or sits unused for weeks at a time, can develop lubrication issues, gasket wear, and timing inaccuracies long before its movement would naturally need service.
Most collectors don’t realize the damage is happening until they pick up a favorite piece and notice it’s running fast, slow, or not at all. The good news is that nearly every one of these problems is preventable. Below are ten storage habits that quietly wear down automatic watches, along with what to do instead.
1. Leaving an Automatic Watch Sitting Still for Weeks
Automatic movements rely on the natural motion of your wrist to keep their mainspring wound. When a watch sits untouched in a drawer, the lubricants inside the movement settle unevenly, and in some cases the mainspring can lose tension entirely, causing the watch to stop.
This isn’t catastrophic on its own, but repeatedly letting a movement run dry and then restart puts more wear on the gear train than steady, consistent operation would. If you rotate between several watches, this is one of the most common ways a “healthy” watch ends up needing early service.
2. Storing Watches in a Drawer With Loose Jewelry or Keys
A watch case and crystal are more delicate than they look. Tossing a watch into a drawer alongside rings, keys, or other jewelry is one of the fastest ways to pick up hairline scratches on a sapphire crystal or dents on a bracelet clasp.
A dedicated storage solution keeps each piece separated and cushioned. This is really the core purpose of a proper watch box: individual, padded compartments that prevent metal-on-metal contact. If you’re building out a collection and don’t already have dedicated storage, it’s worth browsing something like Aevitas’ range of watch boxes, which are designed specifically to hold multiple pieces securely without crowding them.
3. Ignoring Humidity and Temperature Swings
Movements are sensitive to environmental extremes. High humidity accelerates corrosion on steel components, while rapid temperature changes can cause condensation to form inside the case, especially if a gasket has aged or wasn’t properly sealed during a previous service.
A stable, moderate environment, ideally somewhere between 40–50% humidity and away from direct sunlight or radiators, is far better for long-term storage than a bathroom cabinet or a spot near a window.
4. Using the Wrong Watch Winder Settings
For those who keep an automatic watch running continuously between wears, a winder is a genuinely useful tool. But using an incorrect rotation direction or turns-per-day (TPD) setting can actually be worse than not using a winder at all, since it forces the mainspring to work against its intended winding direction.
Every movement has different requirements. An Omega Co-Axial calibre, for example, needs different TPD and rotation settings than a standard ETA movement. If you’re setting up a winder for the first time, it’s worth checking a movement-specific reference like Aevitas’ guide to the best watch winders for Omega watches before assuming a generic setting will work.
5. Stacking Watches on Top of Each Other
It sounds obvious, but stacking watches, even briefly while switching between them, is a common cause of scratched case backs and bent bracelet links. Bracelets in particular are prone to pressure marks when weight is applied unevenly across the links.
Each watch should have its own resting space, whether that’s a dedicated slot, a cushion, or a watch roll, rather than sharing a surface with another piece.
6. Forgetting to Check Gaskets and Water Resistance Ratings
Water resistance isn’t permanent. Rubber gaskets in the crown, case back, and crystal degrade over time, and a watch rated for 100 metres of water resistance when new may not hold that rating five years later without maintenance.
This matters for storage too: a watch with compromised seals is more vulnerable to humidity damage even when it’s just sitting in a drawer, not just when it’s submerged. Most manufacturers recommend a gasket check every 12–24 months, even for watches that are rarely worn in water.
7. Storing Leather Straps Flat and Unrotated
Leather straps need airflow to avoid cracking, and folding or curling them into a small compartment for long stretches accelerates wear. If a watch with a leather strap goes unworn for an extended period, laying it flat or on a slight curve, similar to how it sits on a wrist, helps the leather keep its shape.
Rotating leather-strapped watches into regular use, rather than leaving one strap under constant tension while others sit idle, also extends the life of the leather significantly.
8. Keeping Watches Near Magnetic Devices
Phones, laptop speakers, and even some bag clasps contain magnets strong enough to affect a mechanical movement’s hairspring. A magnetized hairspring causes a watch to run significantly fast, sometimes by several minutes a day, and it’s one of the more common issues watchmakers see that owners never expect.
Storing watches away from speakers, tablet covers with magnetic closures, and wireless chargers is a simple habit that prevents an otherwise unnecessary trip to a watchmaker.
9. Overlooking the Value of a Dedicated Display or Storage Setup
Beyond protection, how a collection is stored affects how often pieces actually get worn and appreciated. A drawer full of watch pouches makes it easy to forget about pieces at the back, while a proper display case keeps every watch visible and easier to rotate through regularly.
For collectors building toward a more organized setup, it’s worth looking at what a specialist retailer offers rather than assembling a mismatched set of boxes and cushions over time. Aevitas has built its catalogue specifically around this problem, offering storage and winding solutions sized for everything from a handful of watches to larger collections.
10. Assuming All Watches Have the Same Storage Needs
A quartz dress watch, a dive watch, and a vintage automatic all have different storage priorities. Quartz watches don’t need winding but do need their batteries checked periodically to avoid leakage damage. Dive watches benefit from regular gasket checks given their water resistance claims. Vintage pieces are often more sensitive to humidity and temperature than modern ones, since older lubricants and materials degrade differently.
Treating an entire collection the same way, rather than accounting for these differences, is one of the more overlooked mistakes even experienced collectors make.
Final Thoughts
Good watch storage isn’t about buying the most expensive box or winder available. It’s about understanding what each piece in a collection actually needs, whether that’s consistent motion, protection from magnetism, or simply a dry, stable environment, and building habits around that. A few small changes, like separating pieces properly, checking winder settings, and rotating leather straps, can add years to a watch’s condition between services.
For anyone serious about longevity, it’s also worth reading up on movement care from a source dedicated to horology, such as WatchTime’s guide to mechanical watch maintenance, which covers servicing intervals and movement care in more technical detail than most retailers go into.
FAQs
How often should an automatic watch be worn to stay accurate?
Wearing an automatic watch at least a few times a week keeps the mainspring consistently wound. If a watch will sit unused for more than a week, a properly configured winder is a good alternative to manual winding.
Can a watch winder damage a watch if used incorrectly?
Yes. Using the wrong rotation direction or an excessive number of turns per day can put unnecessary strain on the mainspring. Always check the manufacturer’s recommended TPD and direction before running a winder long-term.
What’s the ideal humidity level for storing watches?
Most watchmakers recommend somewhere between 40% and 50% relative humidity, with stable temperature and no direct sunlight exposure.
Do quartz watches need any special storage care?
Quartz watches don’t need winding, but batteries should be removed or checked periodically if a watch will be stored for an extended period, since a depleted battery can leak and damage the movement.
How do I know if my watch has been magnetized?
A magnetized watch typically runs noticeably fast, often gaining several minutes a day. If timing suddenly changes without explanation, magnetism is one of the first things a watchmaker will check.
