I think that look is stupid and impractical.
In the old days, mechanical gauges had to be outside the cabin as they had to have the measured fluid running through the gauge unit itself (eg oil pressure gauge had an oil line through it).
Nowadays with electronic gauges there is no need for them to be placed outside.
If you have them outside, you can get water in the electronics of the gauge during rain and in inclement weather you can't even see the gauges.
