The Monte Carlo series were the first chronographs produced by Tudor and are instantly recognisable by the distinctive dial with angled blue subsidiary dials instead of the more normal circular subsidiaries used by the other chronographs of its time. This striking dial combination of vibrant orange and blue have been translated into the Heritage Chrono Blue range giving the 70s design a contemporary freshening up whilst retaining its distinctive style.
