Watch-sized computers-enough compute power?

[Kauaiguy]

Suunto, Mares and others have brought out watch-sized dive computers. With current technology is it possible to package enough compute power in that form factor to adaquately perform the needed computations? In particular, can full-up RGBM be done? Are these offerings merely "pretenders" or has technology reached the threshold allowing a "real" dive computer to be scaled to a watch?

Size isn't a limiting factor for nearly any computing task these days, and the RGBM algorithms are actually fairly simple.

Power, power dissipation, and readability are the real engineering challenges that affect physical size.
