The Ulysse Nardin El Toro/Black Toro GMT Perpetual ref. 326-03-3 is fitted with a very robust solid 18K rose gold case measuring 43mm in diameter and topped off with a fixed black ceramic 24-hour bezel and a black rubber strap with deployant buckle. El Toro, is perhaps the most robust and most user friendly Perpetual Calendar out there that also happens to also come with a sophisticated dual time zone complication. This watch is fitted with a stunning black dial with Côtes de Genève that could be perceived as slightly busy but somehow its striking design and beauty makes all elements flow nice and evenly. The dial features the traditional oversized skeletonized hands with luminescent material on the tips, day and month apertures next to the center pinion, seconds register at 9, year aperture at 6 and big date aperture at 1 o'clock. The black dial is nicely accentuated and balanced by the blued screws and the gold accents.
