About This Design
Gravitational Blueshift Watch
A multi-coloured, fractal representation of gravitational blueshifting; the shifting of light towards the blue end of the spectrum that occurs as photons become more energetic when falling into a gravity well. Unlike the more commonly known Doppler blueshift, an apparent effect which is the result of motion towards the observer, gravitational blueshift is real, independent of the received angle of the photon. Gravitational blueshift is a natural consequence of conservation of energy and mass-energy equivalence.

Great little watch, good sturdy quality, actually surprised how weighty it is, a very eye catching timepiece with the rhinestone bling . Improvements would be, bigger hands, numbers that stand out more and add some luminescence . The hands and numbers blend in with the background a bit much .
