Running fully wound constantly equals best possible timekeeping. Although your automatic watch will likely run just by wearing it (if it is in good condition) you will get much better accuracy by fully winding it manually before wearing it. All moving parts in a watch require lubrication to reduce friction.

Is a fully wound watch more accurate?
In fact, the factors that affect the accuracy of a watch’s timekeeping are mainly in use, with the clockwork torque having the greatest impact on the oscillation. A hand-wound watch needs to be fully wound every day, and when it is fully wound, all indicators of the watch will be better.
What causes a watch to run fast?
If a watch suddenly begins running extremely fast (20+ seconds per day to hours fast per day) it is usually an indication that the hairspring coils are magnetized, causing the coils to stick together. This shortens the rotation of the balance wheel and increases the beat rate extremely.
How long does a fully wound watch last?
40 to 50 hours
When fully wound, most automatic watches can run for 40 to 50 hours. Some high-end models can run for days or even weeks. Any modern automatic watch with a movement in good working condition can run for at least 38 hours – this is the minimum power reserve that you will find on pretty much every watch out there.
What happens if you overwind a watch?
Overwinding the watch manually is impossible as well. In case the watch’s mainspring is not wound completely, simply turning its crown will wind the mainspring as it should be. When the mainspring is fully wound, turning the crown of the watch will have no drastic effects on its functionality.
Can you Overwind a Rolex?
Is it possible to overwind a Rolex? If you have a modern day or self-winding Rolex, it is not possible for your Rolex to overwind. If you wind the Rolex too many times, the mechanisms disengage, making it impossible for it to be overwound.
Do automatic watches slow down over time?
The general rule for mechanical watches is that a deviation of 10 seconds or less per day is good. That’s when my customers usually disagree: „But my neighbor tells me that his Rolex has been 100% accurate for five years with no time deviations ever”. Well, simply put: This is absolutely impossible!
How do you fix a watch that runs too fast?
Another way to fix an automatic watch that runs too fast or too slow is by adjusting the movement. This is done by adjusting the balance wheel. It is done so that the balance is adjusted to different positions, which can otherwise affect its accuracy.
Do watches have to break in?
Like most mechanical devices, a new automatic watch (or a watch that has not been used for some time) has a break-in period that lasts for about a month or so. During this time, your watch is distributing the oil around, and is breaking in its gears. You need to wear the watch or have a winder do the job.
Why does my Rolex runs fast?
Modern Rolex watches have either two or four regulator screws on the balance wheel. In order to adjust the time, the screws are turned in (makes the watch run faster) or turned out (makes it run slower). Think of a figure skater doing a spin. When they start to spin, if they pull their arms in, they spin faster.
Is it possible to Overwind an automatic watch?
If you have an automatic watch, it’s not possible to overwind it. If the watch has full power, the rotor inside the timepiece will simply stop spinning. Automatic watches are designed to stop powering the mainspring when it can’t be wound anymore. It’s not possible to over-wind an automatic timepiece.
Does shaking a watch damage it?
You will only damage the watch if you shake it violently. Gently shaking an automatic watch is recommended for some as a means of winding it up as the crown can’t be used to wind them up!
Should I wind my watch everyday?
Try to wind your watch once a day. A watch typically keeps best time when the mainspring is above half tension. The typical watch has about a two-day power reserve so winding it up before you strap it on each morning is a good habit to form.
How many turns should you wind a watch?
As a rule, it takes approximately 20 to 30 turns of winding to keep your mechanical watch running smoothly. Most manual wound watches offer resistance at the crown when they are properly wound.
How do you know when a Rolex is fully wounded?
For these Rolex watches with hand-wind movements and screw-down crowns, once the winding crown stops rotating, your watch is fully wound. Simply press it back inward and screw it down to the case to ensure your watch’s water-resistance, and you are free to strap it back onto your wrist.
How many turns per day does a Rolex need?
650 TPD
A Rolex watch typically needs around 650 TPD (turns per day) in order to remain 100% wound for the day. A standard setting for a watch winder is considered to be around 750 TPD as this is generally what most modern watches require.
How long should a Rolex stay wound?
about 50 hours
Beckertime state that “When fully wound most Rolex watches will continue to run for about 50 hours until the mainspring fully unwinds and they stop”, so a watch winder is perfect for storing longer than this.
Why is my Seiko watch running fast?
If you watch is still running fast or slow by a large margin the most likely cause is that the mainspring may have gotten itself caught. To get it freed up try this: Place the watch on your palm with the crystal down and slap the watch. If this freed up the mainspring it should start keeping good time.
Why does my watch run slow when I wear it?
If the watch is fully wound and still runs slow, this is an indicator that it is due for maintenance. Most manufacturers of automatic watches recommend movement service approximately every 4 to 5 years, depending on the degree of wear/usage.
What causes a watch to run slow?
Mechanical watch movements are affected by the pull of gravity and can therefore be sped up or slowed down depending on the position of the movement relative to the Earth. If your watch tends to run slow, try leaving it on its side with the crown pointing up at night.
How can you tell if a watch is magnetized?
Watch magnetization is easy to diagnose at home: Place your watch near a compass. If the compass needle moves, your watch has been magnetized.
