Description
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.
Supplied by the brand to the GPHG for its entry.
