Watch accuracy

[ROLEX*]

Hi folks, hope you can help.

If I don’t fully wind the watch and notice once I sync to internet time, to second accuracy, it will tend to slow down few seconds after a short while.

Is the movement normal? Can I say the movement has not yet built the momentum to stabilise (fully charged up)?

How do you ensure highest accuracy?

Thanks and grateful for your advice.

Correct, you need a fully wound mainspring. This is essential for transmission of power from the mainspring to the escape wheel that facilitates the movement of the hands.

For consistency, it’s easier to maintain the same stored energy in a fully wound mainspring which can then be maintained at that level by the winding of the rotor.

Wind your watch every once in a while to top it off if you are not highly active or if the watch isn’t worn consistently.

Can you become more specific?
Which watch/ movement? Age? What is a short while? Slow down how much? The accuracy strongly depends on your wearing pattern as well as many other parameters.

You can go down a compulsive rabbit hole with timing if you wish.

But I would suggest that any watch that runs -10 to +10 per say is doing pretty well.

The newer watches post 2005 should run -3 to +5

If you want to zone in on anything, consistency is the key. And a general rule of thumb, crown down over night to loose a few second as, crown up to gain a few.

And I repeat, consistency is key to a healthy movement.
