Hello. Like my title says.
Chronospace Auto bezel. How is it 200m water resistant?

It's looks like a standard slide rule as found on the standard chronospace, and navi lines.

How do they make this functional and water resistant?
What happens if the slide rule is moved underwater?

Thanks

Joe

Supra,
The Chronospace's slide rule uses a bidirectional bezel with pinion mechanism. Therefore when you spin the bezel, it engages a gearing mechanism which rotates the internal slide rule. The Navies don't have that that's why you should go to the nearest AD and spin both, you will see the great difference in feel. The Chrono feels smooth and mechanically mesmerizing while the Navies feels like hard friction and, in my opinion, underwhelming! This only addresses your comments on the slide rule, the water proofeness of 200m is more than just the slide rule!

Cheers

I'm going from memory right now but I think that 'Breitling The Book' had a diagram that shoes the construction of the gearing mechanism. There is definitely a diagram floating around tha shows it along with all of the different case elements that add to the water resistance. Am on a phone at the moment so not ideally positioned to try and find it.

This one, Roff?

Yep, that's it!
