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.

I loved the ability of designing the watch face, I chose the men’s style as I like a “big watch look”, the leather strap is good quality. Easy to read watch with illuminated hands, great for 24/7 use. I am very pleased with the end result of my design. I have no hesitation in recommending the individualisation of an item. The customisation tools are easy to utilise, you won’t be disappointed. Definitely 5 stars
