Do Rolex watches have batteries?

No. Every Rolex made today is a self-winding mechanical watch with no battery: a rotor winds the mainspring as you move your wrist. The rare exceptions were two vintage quartz models: the Quartz Date 5100 of 1970 and the Oysterquartz, made from 1977 to about 2001. A Rolex left off the wrist will stop after roughly two to three days; just wind it and set it.

Power reserve (modern)	About 70 hours on most models
If it stops	Wind the crown 20 to 40 turns
Service interval	About every 10 years

How a Rolex is powered

Rolex patented its Perpetual rotor in 1931: a half-moon weight that spins as you move and winds the mainspring. Every Rolex Oyster Perpetual since works the same way. Most current Rolex movements (the 32xx generation) store about 70 hours of power, so a Rolex taken off on Friday evening will usually still be running on Monday morning.

The exceptions: Rolex's quartz watches

In 1970 Rolex released the Quartz Date 5100, built around the Beta 21 movement developed by a group of Swiss watchmakers. Only about 1,000 were made, in gold.

During the quartz boom of the 1970s, Rolex joined other Swiss makers in developing quartz movements, and from 1977 sold the Oysterquartz Datejust and Day-Date, with an angular integrated case and a high-quality quartz movement of its own. It was made until around 2001. It is now a collectible curiosity, and, with the 5100, one of only two Rolex families that ever needed a battery.

What to do if your Rolex stops

Unscrew the crown (most Rolex crowns screw down against the case).
In the first position, turn it clockwise about 20 to 40 times to wind the mainspring.
Pull it out to set the date and time, avoiding date changes in the late evening and early morning hours.
Push and screw the crown back down firmly, so the watch stays water-resistant.

If it stops again after a day of wear, or runs very fast or slow, it may need a service; Rolex recommends roughly every 10 years.

My "Rolex" ticks once a second. Is it fake?

A seconds hand that jumps once per second is the sign of a quartz (battery) movement. Unless it's a vintage Rolex quartz model, a ticking "Rolex" is almost certainly counterfeit. A genuine modern Rolex's seconds hand moves in small, smooth steps, 8 per second. See why Rolex watches are so expensive.

Questions people ask

Do Rolex watches need batteries?

No. All current Rolex watches are self-winding mechanical watches. Only two rare vintage models, the 1970 Quartz Date and the Oysterquartz, used batteries.

How long will a Rolex run when not worn?

About 70 hours for most current models; older ones about 2 days.

Do I need a watch winder for my Rolex?

No. If it stops, simply wind and set it. Winders are a convenience, not a necessity.

Does a Rolex tick?

Its seconds hand moves in tiny steps, about 8 per second, so it looks smooth. A Rolex that ticks once a second is either a rare vintage quartz Rolex or a fake.

What does Rolex mean?

The name has no official meaning. Founder Hans Wilsdorf registered it in 1908 because it was short, easy to say in any language and fit on a dial.
