Again, because we don’t have to perform several movement services so that the movement breaks in (as we have to do with an engine so that it breaks in)

The dynamics associated with engine break-in are different and can be different for vastly different engines.
Some engines are best handled with an intial break-in of twenty minutes at a set of revs in neutral in the w/shop with lighter valve springs. After that the oil is dropped and the heavier(propper) valve springs fitted.
Then the on road component of the engine break-in is carried out.
Other engines which are designed for different applications are only required to run the factory fill oil until the first scheduled service with no elaborate oil change schelules what so ever, and will indeed perform well for the entire time an owner is likely to own the vehicle.

The engine and watch movement analogy is a very poor comparison really.

Absolutely
The diff in my mother in law's 2004 model car is starting to howl at times but she doesn't know it.
To her, it's all normal but it's got nearly 300,000 kms on the factory fill and she drives it around town.
I reckon it'll see her out at this rate though as she's pushing 80
It'll become a problem for one of her Grandkids eventually

Agreed.
There would be so much going on with such a neglected movement it would in all likelihood be US anyway.
Perhaps another one of those watches sitting in the back of a drawer somewhere in the house destined to become an heighloom, and replaced twice over with a cheap quartz.

I put it to you, the 30 year figure you hold out there is for the most part fantasy. Most watches which are worn daily will have stopped working well before then or been such poor timekeepers the owner would've long moved on to another source of the time. 40 years functioning properly is beyond belief.
I have over 60 year old unopened Omega and some other watches inherited from my grandfather...It will probably be impossible to service such old watches as most movement parts of a watch from 1950s - 1960s would be unavailable.

Do Our Rolex Watches "Break In"

I didn’t know that not all break ins require elaborate oil changes.

That the engine and watch movement analogue is a poor comparison, is part of my point

I ask why engines require elaborate oil changes to break in, and watches don’t

But I think you answered it with your explanation of synthetic oils and transmissions and all

Thanks for the feedback!

Lots of all this figures in but in the real picture it will only go around so many times before it starts having issues regardless of what we are talking about .. Watches, appliances , or any sort of pump etc.

Engines have internal combustion happening. Watches don't can't compare both !

According to a Frederico Talking Watches episode on 5 Great Watches Ruined by 5 Flaws, shavings are produced. He was referring to an IWC plagued with what he called "micro-pollution."

At this point it’s pretty clear to me that they are.

However, it’s also clear that not enough shavings are produced during the break in period to require elaborate services during break in

long before that rolexes will die from lack of oil we will die.

So I dont care. I only care is time keeping overall its watch. If it becomes loosing time I will sent it to repair.

If it will be discontinued bad luck for my son it will be his responsibility to take care of it. I will be long gone.

Engine analogy is wrong, that tiny metal particles will be moving to the sides of the watch. ın my opinion wrist movement and temperature difference effect more.

Again I dont care, I will take it to the service every 10 years and thats it as long as I live.

Quite right.
Also watches are for the most part, hermetically sealed and as a result don't suffer the effects of moisture content in the oil which is made worse by short trips with moisture accumulating because of condensate.
With regard to the internal combustion process. It could be described as being similar to having a small thermal reactor(especially in the ring pack region).
Not to mention varying degrees of the effects of fuel dilution issues or potential coolant/glycol contamination.

Yes. Engines and watch movements are vastly different scenarios and it's impossible to compare operating conditions on any level.
