AdC17 Only Watch

AdC17
Some time after the creation of the AdC8, our first Split-seconds chronograph and finalist in the chronograph category of GPHG 20, we are very happy to present our second one; the AdC17. As all our timepieces it is a unique piece created especially for a customer. This time, this rattrapante has 2 counters and it is based on a calibre Venus 179.  One of the most challenging works of this project has been to design a very unusual dial with a tachymeter scale made in KNOTS because the aviation is one of the passions of our customer.

Case
The ergonomic case with tear-drop lugs has been re-adapted from the AdC8 case size to a diameter of 39mm. It combines 2 materials: 18k Grey gold and 18k Rose gold for the pushers and the crown. This combination offers an extremely elegant look that also fits perfectly with the two-tone rose dial and the hands.

Dial
The tachymeter scale calculated and designed in Knots makes even more unique and original this timepiece. There is also a secret meaning on the number 52 that appears stamped in blue. The two-tone rose galvanic dial combines applied rose gold serif indexes and rose gold Breguet numerals in perfect balance for a clean timeless look. The two engine-turned counters combine perfectly with the 6 hands; 3 of them made in 18k rose gold and 2 in blued-steel, according to the vintage chronograph look.

Movement
An elegant visual effect thanks to the combination of the palladium plated bridges, the pink gold plated wheels, the steel accents and the black polished parts. At the center, once again, a rattrapante wheel made of Titanium with the AdC symbol.
