Some people will think that taking a watch apart and re-assembling it is akin to watching paint dry.
Others will be enraptured by the notion of the mind of man conceiving such an intricate mechanical device, and awestruck at the dedication it takes to acquire the knowledge to reversably deconstruct such a wonder.
I find myself in the latter camp, and offer this video to my fellow-travelers:
[Rolex Submariner Watchmaking Demonstration | Watchfinder & Co.] (Viewer #372,548)

now do that with a living human being, time constraints and all the lawyers in the US breathing down your neck.
I would have parts left over at the end.
Gotta have the right tools. I’m out of practice, but laptops are pretty close to my limit.
This is somewhat similar, except lower resolution and more energetic music:

Wow.
That was as cool as the day is long.
Frank, thanks for sharing that.
Not that I did not already possess a healthy respect for that brand and particular watch, it is now a wee bit more profound.
The guy takes apart, cleans and puts watches back together again, which is a delicate and precise set of skills.
But somewhere there’s a guy who makes those teeny tiny screws that hold the whole thing together, and that’s gotta take a whole other scale of precision!
