The ad on the site is ironic.

In my case it shows a Nomos Metro watch.

Which is so much better than the watch advertised.
With 2500€ you get an in-house movement from top to bottom (balance wheel, spring, escapement, etc.), which means flexibility in design (it shows, with the off center reserve dial and the huge outer edge date dial), and finer tuning for better accuracy.

And they're asking 17000€ for a generic off the shelf ETA movement.

Not to mention that the clean, Bauhaus-y look and feel of the Nomos, along with the hand made craftsmanship is a better match to Leica in spirit, compared to this overpriced bloated timepiece.
