Key Takeaways
- Manual winding is a perfectly valid way to keep an automatic watch running, but it requires consistency and daily attention.
- Watch winders are most useful for collectors with multiple automatic watches or those who rotate pieces infrequently.
- Neither method causes inherent harm to a well-maintained modern automatic movement when used correctly.
- Over-winding is not a concern with automatic watches, as they have a slipping clutch mechanism that disengages once fully wound.
- The right choice depends on how many watches you own, how often you wear them, and how involved you want to be in their daily upkeep.
- A watch winder is an investment in convenience and consistency, not a replacement for proper watch maintenance.
If you own an automatic watch, you have probably thought about the best way to keep it running when you are not wearing it. For some people the answer seems obvious: just wind it by hand each time you put it on. For others, a watch winder feels like the smarter, more considered choice. The honest answer is that both approaches work, and both have genuine trade-offs worth understanding before you commit to one or the other.
At Lux Watch Care, we work with collectors across Australia who range from people with one cherished automatic to those managing collections of twenty or more pieces. The winder-versus-manual question comes up constantly, and it rarely has a single correct answer. What it does have is a clearer framework for thinking through the decision, which is what this post aims to provide.
How Automatic Watches Actually Work
Before getting into the comparison, it helps to understand what is happening inside the watch. An automatic (self-winding) watch winds itself through the motion of your wrist. A rotor - a semicircular weight - spins freely as you move, and that rotational energy winds the mainspring. When the watch is not being worn, that process stops, and the mainspring gradually releases its stored energy until the watch eventually stops.
The length of time a watch can run without being worn is called its power reserve. Most modern automatic movements have a power reserve somewhere between 38 and 72 hours, though some higher-end movements extend well beyond that. Once the power reserve is exhausted, the watch stops and will need to be either wound or worn to restart.
Manual Winding: The Case For It
There is something satisfying about winding a watch by hand. It keeps you actively connected to the object, and for many collectors that engagement is part of the appeal of owning mechanical watches in the first place. If you wear a watch every day, your natural wrist movement will likely keep it wound without any manual intervention at all.
For a single-watch collector, manual winding is often the most practical approach. There is no additional equipment to buy, no settings to configure, and no motor running in the background. When you pick up your watch in the morning, a quick crown rotation brings it back to a full charge if needed, and you are done.
Manual winding also avoids any concerns about placing the watch in a winder for extended periods. Some collectors prefer to have direct control over their watch's daily operation rather than delegating that to a mechanical device.
Manual Winding: The Limitations
The limitations of manual winding become more apparent as your collection grows. If you own three or four automatic watches and rotate between them, keeping each one wound manually becomes logistically awkward. A watch that has been sitting for four or five days will have lost its power reserve entirely. When you come back to it, you will need to wind it, set the time, and possibly reset the date depending on the complication. Multiply that across several pieces, and what felt simple starts to feel like a chore.
There is also the question of accuracy and consistency. Automatic movements are designed to run continuously. Starting and stopping the watch repeatedly over weeks or months, while not directly damaging, can contribute to minor variations in timekeeping as the watch repeatedly goes through the process of running down and being restarted. This is a mild concern rather than a critical one, but it is worth acknowledging.
Additionally, if you wear different watches on different days, manual winding requires you to track which pieces need attention - something that is easy to forget when life gets busy.
Watch Winders: The Case For Them
A watch winder solves the consistency problem almost entirely. It keeps your automatic watch moving continuously, mimicking the wrist movement that would otherwise power the rotor. A properly configured winder maintains your watch at or near full power reserve at all times, meaning it is ready to wear the moment you pick it up. The time and date remain set, and the movement stays lubricated through regular operation.
This is particularly valuable for watches with complicated functions such as perpetual calendars or annual calendars. Resetting these complications after the watch stops can be time-consuming, and doing it incorrectly can potentially cause damage. Keeping the watch wound through a winder eliminates that concern entirely.
For collectors who rotate frequently, a winder is essentially a form of active storage. Rather than leaving a watch idle in a box, the winder keeps it ready. When you reach for a piece you have not worn in two weeks, it is already running correctly.
If you want to understand more about the mechanics behind this process and how winders translate rotation into winding energy, our overview of how watch winders function and what they do for your movement covers the subject in accessible terms.
Watch Winders: The Limitations
The main limitation of watch winders is that they require the right settings to be used correctly. Every automatic movement has a specific requirement for turns per day (TPD) and rotational direction - clockwise, counter-clockwise, or alternating. Using the wrong settings does not necessarily cause immediate harm, but running a watch on significantly higher TPD than its movement requires is not ideal practice over the long term.
The solution here is to look up the specifications for your specific movement and configure the winder accordingly. Reputable winder products allow you to adjust these settings, and our guide on dialling in the correct rotational settings for your movement walks through how to approach this for different watch types.
The other consideration is quality. A poorly made winder with a noisy or inconsistent motor is not the experience you want alongside a collection of well-crafted timepieces. This is an area where cutting corners tends to produce frustration rather than savings.
Are Watch Winders Safe for Automatic Watches?
This is one of the most common concerns people raise, and it deserves a direct answer. Modern automatic watches are equipped with a slipping clutch mechanism. Once the mainspring is fully wound, this clutch disengages, which means the rotor can continue spinning without transmitting any additional energy to the spring. You cannot over-wind an automatic watch through normal use or through a correctly functioning winder.
Older, vintage movements may have different considerations, and it is worth checking with a watchmaker if you are uncertain about a specific piece. For modern automatic movements, though, a winder running at appropriate settings poses no mechanical risk to the movement itself. Our post on whether watch winders are genuinely safe for automatic movements covers this topic in more detail if you want to read further.
Choosing the Right Winder
If you decide a winder is the right choice for your situation, the product you select matters. At Lux Watch Care, our range of automatic watch winders is chosen with exactly this kind of collector in mind - pieces that prioritise build quality and configurability over price-point compromises.
For those starting with a single watch, our single slot wooden automatic watch winder with glass display offers both function and presentation in a compact form. For collectors managing two watches simultaneously, the 2 slot automatic watch winder provides independent operation for each piece. And for those who want the quietest possible operation from a single-slot unit, the single slot automatic winder with Mabuchi mute motor is a thoughtful choice, particularly for bedroom placement.
What If You Do Not Want a Winder?
If you decide that manual winding suits your situation better, that is a perfectly reasonable conclusion. In that case, proper passive storage becomes more important. A quality watch box or watch roll keeps your pieces protected from dust, scratches, and humidity while they are not being worn.
The key is that watches in passive storage should still be wound periodically to keep the movement lubricated. Leaving an automatic movement completely dry and static for months at a time is harder on the oils in the movement than keeping it in use. Even a manual wind every week or two during periods of non-wear is beneficial.
Making the Decision
The simplest way to think about this choice is to ask yourself two questions. First, how many automatic watches do you own and rotate between? If it is one, manual winding is likely sufficient. If it is three or more, a winder starts making practical sense. Second, how often do you wear each piece? If a watch sits unworn for weeks at a time regularly, a winder keeps it accurate and ready without the hassle of resetting.
There is no universally correct answer here, and the watch community genuinely holds both positions with good reason. What matters is that whichever approach you choose, you are giving your collection the consistent care and attention it deserves.
At Lux Watch Care, we are here to help you find the right solution for your specific situation. Whether that means a premium winder, quality passive storage, or a combination of both, we are happy to point you in the right direction.

Frequently Asked Questions
Is manual winding bad for an automatic watch?
No. Manual winding is a normal and appropriate way to wind an automatic watch. Most automatics have a crown that allows hand-winding, and doing so correctly causes no harm to the movement. The key is not to force the crown beyond resistance and to stop once you feel the mainspring is fully tensioned.
Can you over-wind an automatic watch with a watch winder?
In practice, no. Modern automatic movements include a slipping clutch that disengages once the mainspring is fully wound. This mechanism prevents over-winding regardless of whether the energy comes from wrist movement or a winder. Vintage movements may vary, so it is worth consulting a watchmaker for older pieces.
How many turns per day does an automatic watch need in a winder?
This depends on the specific movement. Most automatic watches require somewhere between 650 and 1,000 turns per day, though some movements need more. The manufacturer's specifications or service documentation for your watch will provide the accurate figure. Running a winder significantly above the recommended TPD is not considered best practice.
Does a watch winder keep the time accurate?
A watch winder keeps the movement running continuously, which means the time and date remain set. However, the accuracy of the timekeeping itself depends on the movement's own precision and regulation, not the winder. A well-regulated movement will keep time accurately whether wound manually or by a winder.
Is it worth buying a watch winder for one watch?
It depends on your habits. If you wear the same automatic watch every day, a winder adds little practical benefit since your wrist movement keeps it wound. If you frequently leave it unworn for several days at a time, or if the watch has complicated functions that are tedious to reset, a winder may be a worthwhile convenience.
What happens if I leave my automatic watch unwound for a long time?
The watch will stop once its power reserve is exhausted. Beyond that, extended periods of complete stillness allow the lubricating oils inside the movement to settle and potentially thicken or dry in areas that need consistent coverage. Periodic winding during storage, even without wearing the watch, is generally recommended by watchmakers.
Should I use a watch winder or watch box for storage?
These serve different purposes. A watch winder keeps an automatic movement running continuously and is best for watches in regular rotation. A watch box provides protective passive storage and suits watches worn daily or pieces not requiring continuous winding. Many collectors use a combination of both depending on which pieces they are actively rotating.
