Does a watch tend to run faster in time
Due to the watch lubricants get thicker
Over the years
I was told that if a watch is running slow after service
It will speed up as the oils get thicker
How long does it take for this to happen?

is this a haiku?

The oils are synthetic. AFAIK the viscosity stays consistent and I cannot see a reason they would thicken. I would imagine as moving parts wear over the years that very fine metal particles likely contaminate the lubricants. If your movement is running slow beyond acceptable limits, send it in to a watchmaker for regulation.

If the lubricant got more viscous over time it would slow the watch down.

Sounds like nonsense to me but, as always happy to be corrected.

I don’t have to get it regulated for it only 1 spd slow well with in Rolex specs of
-2

Old mineral oils would thicken and gum up but as already answered modern oils are synthetic so do not suffer from this. Modern oils can dry up if left too long between a service.

A movement can speed up due to dried out oils because the balance amplitude (that is the degrees of swing left and right) is reduced which has the same effect of speeding up the movement. So a fast running movement would indicate the need for a service.

Thanks for the information

These two posts explain it perfectly
