Thanks for your answers! Relativity it is then!
I just thought Doppler may have an effect but then thinking about it it may just affect the 'colour' of the clock as you see it as you are travelling towards it?

Red turns to green at less than 1/4 c. This is attributable almost entirely to the Doppler effect . . . relativistic effects are minimal (2~3%) at such velocities.
You would however probably begin to notice some other rather bizarre modifications (other than colour shift) in your external surroundings travelling at 1/2c, among them, a contraction of the field of view ahead of you.
