What is an automatic watch winder?

Watch winder is a device with an electrical motor which will automatically wind your watch when you are not wearing it. It will maintain your watch in working condition so that it is ready for use at any moment. On top of that, the watch winder provides a uniform distribution of oil inside the watch. That is, your watch movement will always stay oiled even if you do not wear it for a long time.

Why should one use the watch winder?

Automatic watches have a limited power reserve, so if you stop wearing them and winding them up, they will run down in two or three days. This depends on the watch brand and on movement (caliber) used. When your watch stops, you must reset time and wind up your watch. If your watch has additional functions (such as, calendar, lunar calendar, perpetual calendar), their resetting may take up quite a lot of time and require certain skills. Additionally, watch movement should work continuously in order to secure movement lubrication.

What types of watches are there and which ones benefit from watch winders?

AUTOMATIC or SELF-WINDING watches. These watches wind themselves using body movement. The wearer's arm actions cause a weight behind the movement to rotate, winding the main spring. They can also be wound manually. None of the following watches should be used on our watch winders: Mechanical - these traditional 'wind up' watches. They work because of a mainspring inside the watch that needs to be wound by popping out the crown on the side of the watch and turning it. Quartz - powered by batteries. Kinetic - these appear to be self-winding but are actually not. They need a much more violent movement to stay wound. We do not know of any watchwinder that will wind Kinetic watches.

Is there a danger of "over-winding" when the unit is turned on 24 hours, 365 days a year?

There has been a lot of discussion about this topic. Here is the discussion that is presented by ROLEX in a booklet that accompanies their Rolex Oyster watches: "The perpetual rotor is an innovation...patented by Rolex in 1931. ...a semi-circular rotor...winds the main spring. Once the optimum tension is reached, a special slip clutch prevents overwinding...and has been generally adopted throughout the watch making industry." Some manufacturers have also prevented their watch from being wound in the counter clockwise direction to add additional reduction in the winding of the main spring. All of our winders either can be set to run in either direction or they automatically change direction to incorporate both clockwise and counter-clockwise winding of your watch. Watchwinders will not wind a watch that is not already wound. Make sure your watch is properly wound prior to placing it on the winder. Winders will maintain the power reserve but normally with not wind a watch that is not at least 50% of the reserve prior to being placed on the winder.

How long should I keep my watch on the watch winder?

You can not overwind the watch. It needs about 8 hours if it is running low. Less if the power reserve is higher.

Which is the recommended direction for a Rolex watch?

It does not matter if the the Rolex is made after 1972.

What is the correct setting for my watch?

All automatic watches have different TPD requirements but on average most automatic watches need a minimum of 650-1200 TPD. All of our watch winders are set to accommodate this minimum requirement.

To find the right setting for your watch we recommend the following procedure:

  • Manually wind the watch by turning the crown 20-30 times. The watch winder will not wind a completely dead watch.
  • Set the winder to the lowest TPD setting and bi-directional rotation. Place the watch in the winder and make sure it is seated properly and securely in the holder.
  • Turn the winder on and periodically check to make sure the time is correct. Most automatics have a maximum of 40 hours of power reserve when fully wound so if the time is correct after 2 full days, this is the proper setting for your watch.
  • If the time is incorrect, please set it to the next highest TPD setting and try again.
  • If the time is incorrect, please set it to clockwise only and try again.
  • If the time is incorrect, please set it to counter-clockwise only and try again.
  • If the watch works while it is being worn but does not work in the winder, it may need to be serviced. When a watch is worn, the movements it experiences are not as smooth as in a watch winder, so while a watch may work when its worn it may not work when in the winder. Watch winders move very smoothly so if the lubrication inside the watch has congealed from not being in use, the watch may need to be serviced.

How many TPD does a Rolex need?

600 TPD

That is the number of turns of the internal rotor that is required each day to keep the particular watch wound. Most automatic watches require 500 to 800 TPD although there are others with longer power reserves that need 1300 TPD. For example, a Rolex President needs about 600 TPD.
