Is there such a thing as „Lubricate/Oil a movement“ without full service

[aasubo]

Often you read:

No service necessary, watch runs within specification, but due to age (maybe 10 years plus) it was lubricated / oiled and it got new seals for water resistance.

Is this such a lazy move on behalf of a seller to suggest a maintained watch to the customer or does actually deliver a result and can this even be done without taking apart the movement of the watch?

Thanks for all answers!

10 years is a long time even if the watch runs good. The oils have a shelf life, plus the wear they receive while watch runs. Issue is the oils break down, grease, grime etc build up which causes more friction and reduces life span on parts which in return can increase a service cost.

I figure it's like a bike chain or a car engine, gotta re lube it to keep it going

If a watch needs fresh oil it needs a service. You can’t go putting new oil on top of old oil. Only a charlatan would do that.

Just curious - surely to properly oil or lubricate it, it would have to be taken apart in any event?

Thanks for the insights, I thought so, too. If it needs to be lubricated, it needs a full service

The key is a clean surface for new oils. Cleaning and lubrication.

A Porsche or BMW would not appreciate 6 quarts of new oil over the existing
6 dirty qts left in the engine. Not the best parallel example, but you
get the idea.

So oiling properly means:
Disassembling
Cleaning
Applying lubricants.

What else happens on a “full service”. For example I remember reading that Rolex always ditches the mainspring and replaces, is anything else done as standard?

New mainspring, new crystal if acrylic (new sapphire if damaged), new seals, cleaning and lubing, and replacing any damaged or worn components.

. . .

This is really senseless as you cannot get to all of the grease/oil points without taking much of the movement apart, same for the seals.

Also, as mentioned, what is the point of simply dropping oil on top of dirty or worn parts - nothing is really accomplished.

This sort of statement is a red flag

Thanks for a clear and sound statement. Much appreciated!
