If you own an automatic watch, you have two options when it comes to keeping it wound: wear it daily, wind it manually when it stops, or use a watch winder. But which approach is better for your watch, your lifestyle, and your collection? In this definitive guide, Aevitas UK examines both methods in detail — so you can make an informed decision.
How Automatic Watches Wind Themselves
Before comparing the two methods, it helps to understand how an automatic watch works. Inside the movement is a semi-circular rotor that spins freely as your wrist moves. This motion transfers energy through a series of gears to the mainspring, keeping it wound. When the mainspring is fully wound, a slip-clutch mechanism disengages the rotor to prevent over-winding.
When the watch is not worn for 24–48 hours (depending on the power reserve), the mainspring runs down and the watch stops. At this point, you have two choices: wind it manually or place it in a watch winder.
Manual Winding: The Traditional Approach
Manual winding means unscrewing the crown, winding the watch by hand until you feel resistance, then resetting the time, date, and any other complications before wearing it.
Advantages of manual winding:
- No equipment needed — You need nothing beyond your fingers and a few minutes
- Direct engagement with your watch — Many collectors enjoy the ritual of winding their watch; it creates a moment of connection with the timepiece
- No ongoing cost — Manual winding is free
- Suitable for single-watch collectors — If you own one watch and wear it every day, manual winding is rarely necessary
Disadvantages of manual winding:
- Time-consuming for complex complications — Resetting a perpetual calendar, moon phase, or GMT correctly after a stoppage can take 10–20 minutes and risks errors
- Crown wear — Repeatedly unscrewing and resetting the crown adds wear to the crown tube and gaskets over time, potentially affecting water resistance
- Inconvenient for multiple watches — Collectors who rotate between several watches face constant resetting
- Oil congealing risk — A watch that stops repeatedly allows lubricating oils to pool and congeal, potentially accelerating wear
Watch Winders: The Modern Solution
A watch winder keeps your automatic watch continuously wound by rotating it at programmed intervals, mimicking the motion of the wrist. A quality winder like the Aevitas Single Carbon Fibre Watch Winder offers five TPD settings (650–1,950 turns per day), three rotation directions, and a 12-hour sleep cycle — keeping your watch perfectly wound without any intervention.
Advantages of a watch winder:
- Always ready to wear — Your watch is wound, accurate, and set correctly every time you reach for it
- Preserves complex complications — Perpetual calendars, moon phases, and annual calendars continue running without interruption
- Protects lubricating oils — Keeping the movement running prevents oils from congealing, potentially extending service intervals
- No crown wear — The crown is never touched, preserving gaskets and water resistance
- Ideal for multiple watches — A multi-watch winder keeps an entire collection wound simultaneously
- Beautiful display — A premium winder showcases your collection as well as maintaining it
Disadvantages of a watch winder:
- Initial cost — A quality winder represents an upfront investment, starting from £239 for the Aevitas single winder
- Requires correct setup — You need to set the correct TPD and rotation direction for your specific watch
- Quality matters — A cheap winder with an unshielded motor can do more harm than good
The Over-Winding Myth
One of the most persistent misconceptions about watch winders is that they can over-wind an automatic watch. This is false. All modern automatic movements incorporate a slip-clutch mechanism that disengages the winding system once the mainspring reaches full tension. A quality winder cannot over-wind your watch — regardless of how long it runs.
The 12-hour sleep cycle built into Aevitas winders is not to prevent over-winding — it is to reduce unnecessary motor wear and ensure the winder operates quietly overnight.
Does Manual Winding Damage Automatic Watches?
Occasional manual winding does not damage a modern automatic watch. However, there are two caveats:
Crown wear — Repeatedly unscrewing a screw-down crown (as found on Rolex, Breitling, and many other sports watches) adds cumulative wear to the crown tube threads and the rubber gasket that provides water resistance. Over years of daily winding, this can affect the watch's water resistance rating.
Incorrect winding technique — Winding too forcefully or continuing to wind after feeling resistance can stress the winding mechanism. Always wind gently and stop when you feel the mainspring is fully tensioned.
Which Method is Right for You?
| Situation | Recommended Approach |
|---|---|
| One watch, worn daily | Manual winding — rarely needed |
| One watch, worn occasionally | Watch winder |
| 2–4 watches in rotation | Watch winder — essential |
| Watch with perpetual calendar | Watch winder — strongly recommended |
| High-value collection | Watch winder safe |
| Travelling without watches | Watch winder with battery backup |
The Verdict
For collectors with a single watch worn every day, manual winding is perfectly adequate. But for anyone who rotates between watches, owns complications, or simply values the convenience of a collection that is always ready — a watch winder is the clear choice. The investment pays for itself in convenience, movement protection, and the sheer pleasure of a perfectly maintained collection.
Frequently Asked Questions
Can I use both a winder and manual winding?
Yes. Many collectors use a winder for their primary rotation and manually wind watches that are stored long-term. There is no conflict between the two approaches.
Will a watch winder affect my watch's accuracy?
A quality winder with a magnetically shielded motor will not affect accuracy. An unshielded motor can magnetise the movement and cause it to run fast — another reason to choose a quality winder.
How do I know the correct TPD for my watch?
Check your watch manual or the manufacturer's website. If unavailable, 900 TPD bi-directional is a safe starting point for most movements.
Is it safe to leave my watch in a winder indefinitely?
Yes — provided the winder has a 12-hour sleep cycle and a magnetically shielded motor. Aevitas winders are designed for continuous, long-term use.
