Understated character best describes the Madison Eight-Days with Eterna Spherodrive wristwatch. Its striking textured dial, with twin baton hour markers, cobble-pattern centre and discreet brush-finished surround features an oversized date calendar at two o'clock. Between seven and eight o'clock, a power-reserve indicator keeps track of up to eight full days of energy for its hand-wound movement. And not just any movement – an Eterna Calibre 3510 with a pair of series-coupled barrels working in tandem to deliver 192 consecutive hours of power smoothly and efficiently thanks to the Eterna Spherodrive system. What is more, a cut-off mechanism inactivates the balance wheel after eight days, when the movement's power runs too low for precision timekeeping... another masterful refinement from Eterna.
