Question about tightening torque

[Dog80]

This is a crude translation of a Rolex ad I found in a greek magazine.

Almost as difficult to enter as a bank vault.

Few people in the world are allowed access to the internals of a Rolex Oyster wristwatch. Only authorized Rolex dealers have the technical knowledge and necessary tools. Hermetically sealed on the case - and for those interested on technical details - with a tightening torque of 5M. NEWTON, the backplate of each Oyster, like the Daytona pictured, creates a space that protects the clockwork from shocks, pressure, dust and humidity.

What do they mean by 5M. NEWTON? Tightening torque is measured in Newtons * meters so something is not exactly right. Do they mean 5 meters * Newtons or 5 million Newtons * meters?

They almost certainly mean 5 newton-meters. (Same as 5 meter-newtons.)

Probably. This would be 3.7 ft-lbf or 44 in-lbf. Big freaking deal; I can do that (among other things) with my little finger. Rolexes (and Omegas, and Bvgari) make nice watches–oh, excuse me, chronographs–but the marketing hype about them is unreal. But then, I guess they have to have something to counter the fact that all but the cheapest digital watches keep better time and are more durable at a few percent of the price.

In which of these pairs of words is one NOT like the other?

Indeed. It’s also bullshit that only “authorized Rolex dealers” can open the case of an Oyster watch. All you need is the tool, which is fairly inexpensive as specialty tools go.

This reminds me of the time when, after years of seeing torque referred to in foot-pounds, I first saw it in pounds-feet. Turns out that’s not terribly uncommon, and yes, they’re the same thing.

The torque could be 5 N m or 5 m N. Both are meters times newtons. Only the symbol “N” for newtons should be capitalized unless at the start of a sentence, even though though they honor Isaac Newton whose name would always be capitalized. There should be a space between the number and the first symbol, and a space or a half-high dot or an asterisk or other multiplication sign between the two symbols. If it were written mN it would mean millinewtons, or if written MN then meganewtons. It could also be written meter newtons or newton meters, but I don’t think it’s correct to use one symbol and one word. I don’t know what it means to have no space between the 5 and the first symbol, or to write it as a capital, or to have a period after it (which usually denotes an abbreviation like in English units in. or ft.), or to write the next unit in all caps. Maybe they were shouting…
