About this product
Slate in solid Everose gold under a diamond-set bezel, on the President bracelet. Cool grey against solid rose gold and a ring of diamonds is the most deliberately contradictory watch in the range — the dial refuses the warmth that everything around it insists on. Applied index markers. Calibre 2236 inside, roughly fifty-five hours of reserve, water resistant to 100 metres.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
