Do Watch Winders Damage Watches? Toronto Watchmaker's View

Do watch winders damage watches? It is the question we hear most often at Watchfinder Canada and Watch Winders Canada, and after 25 years in business, 17+ years in Yorkville, our answer is consistent: a good winder set correctly does not damage a healthy automatic watch. A poor winder, the wrong settings, or a watch that needs service can cause problems. This article explains the difference, from the perspective of a Toronto team that buys and sells automatic watches for a living.

Do Watch Winders Damage Watches? The Short Answer

No, not when three conditions are met: the watch is in good running order, the winder is a quality programmable unit, and the turns per day (TPD) and direction match the movement. Under those conditions a winder does what your wrist does, only more gently and more predictably.

Can a Watch Winder Overwind a Watch?

No. Every modern automatic movement has a slipping mainspring, sometimes called a slipping clutch or bridle, that lets the spring slide inside its barrel once it is fully wound. Orbita states plainly that overwinding an automatic is impossible for this reason. Orbita also adds an important caveat: that slipping device should not be overstressed, because it will eventually wear. That is why good winders rest between short winding sessions instead of turning all day.

Why TPD matters more than overwinding

WOLF's guidance is that incorrect TPD settings are unlikely to cause immediate damage, but that too high a setting means unnecessary movement while too low a setting lets the watch run down. The practical risk is therefore cumulative: running a watch at twice the turns it needs, every day for years, adds pointless wear to the rotor bearing and the slipping spring. Use our watch winder TPD settings chart to set the right value.

Watch Winder Wear: Is Constant Running Bad for a Movement?

A watch on a winder is a running watch, and running watches wear. That is true on the wrist as well. The question is whether the wear is worth it. Orbita argues that a watch left stopped for long periods lets lubricants migrate away from critical surfaces, which can cause wear when it is finally worn. Keeping the watch running avoids that, and also avoids the repeated crown use that comes with resetting it every time.

Our view at Watchfinder Canada sits between the two positions. For a modern watch that is within its service interval, the benefits of a winder outweigh the modest extra running time. For a watch overdue for service, we would rather it rest.

Crown and keyless works wear

One benefit is often overlooked. Every time you hand-wind a stopped watch and reset the time, date and any complications, you use the crown, stem and keyless works and work the gaskets. A winder removes most of that handling, which matters for watches with screw-down crowns and complications.

Watch Winder Magnetism and Cheap Winders

The biggest real-world risk we see is not winding; it is cheap, unbranded winders. Common problems include:

•Unshielded motors that sit close to the movement for months, risking magnetisation. A magnetised watch typically runs fast and needs demagnetising.

•Fixed settings that turn too much or too little, or only in one direction.

•Loose or overtight cuffs that let a watch fall or stretch a bracelet.

•Noisy motors that owners switch off, leaving the watch stopped anyway.

A cheap watch winder can cost less than a strap while holding a watch worth thousands. Established brands like Wolf, Heisse & Söhne, Benson, Orbita and Rapport London design their motors and cuffs for long-term use. Even an entry-level programmable winder such as the Benson Compact ALU 1.22 or the WOLF Cub Double avoids the problems above.

When a Watch Should Not Go on a Winder

•A vintage watch with an unknown service history. Have it checked first.

•Any watch that is overdue for service, running erratically or losing power reserve. Rolex, for example, recommends servicing approximately every ten years depending on model and use; other brands specify shorter intervals.

•A watch you wear every day. It does not need one.

•A manual-wind watch. A winder cannot wind it; only the crown can.

•A quartz watch. It has no rotor to wind.

Vintage watch on a winder

We are especially cautious with vintage pieces. Older lubricants and worn parts are better rested than run continuously. If you love a vintage automatic, wind it occasionally, wear it when you can, and let a watchmaker decide whether it is fit for daily running.

Is a Watch Winder Safe for Rolex and Other Luxury Watches?

Yes. Modern Rolex, Omega, Patek Philippe and Audemars Piguet automatics all work happily on a quality winder at the right settings. Rolex rotors wind in both directions, so 650 TPD bidirectional is the usual start; see our best watch winder for Rolex guide for specific models.

How Long Can You Leave a Watch on a Winder?

WOLF says a watch can stay on a winder continuously when it is not being worn, provided TPD and direction are correct. In practice we suggest wearing each watch from time to time, checking that it is keeping good time, and following the manufacturer's service interval.

How to Use a Watch Winder Safely

1.Make sure the watch is running well and within its service interval.

2.Wind it fully by hand or wear it before putting it on the winder.

3.Set TPD and direction for the calibre, starting low.

4.Fit the cuff with the bracelet or strap closed, snug but not stretched.

5.Keep the winder away from speakers, phones and other magnetic sources.

6.Check timekeeping after a few days and adjust TPD if needed.
