Abstract (en)

[origin: EP2757425A2] The timepiece has a case for housing a clockwork movement (1) that includes a mechanical energy source i.e. spring (12), and a counting mechanism for counting power reserve of the spring including a counting mobile unit i.e. differential gear (16). Polarized transparent elements formed by transparent disk and a disk (6) are superimposed and visible from outer side of the case. One of the elements includes kinematic connection with the counting mobile unit such that angular orientation between the elements is a function of value of the power reserve at every moment.
