Staying true to the original production plans, the model makes a statement with an interesting tonneau shaped case and a gradient dial in warm tones that darken towards the edges. A faithful reproduction housed in a 37mm steel case, the smoked brown gradient dial features three white counters and a distinctive vignette effect that darkens towards the edges. A red central chronograph hand adds an element of colour to the monochrome dial, while a tachymetric scale, date display at 4 30, and small seconds at 9 oclock enhance functionality. Power and precision come courtesy of the el primero 400 movement. Originally introduced in 1969 as the worlds first automatic chronograph calibre, today the movement is still renowned for its unrivalled precision. A steel ladder bracelet completes the look.
