The Swiss watchmaker reinterpreted its Anniversary Heart for this year’s Only Watch charity auction that will take place in Monaco, on September 22. This luxury, one-of-a-kind watch is the first ever hand-made skeleton model that incorporates the iconic Cricket alarm Caliber V-19.

Vulcain Anniversary Heart Only Watch 2011
The unique Vulcain Anniversary Heart Only Watch 2011 is a true masterpiece, with a spectacular mechanism, decorated manually by the brand’s best craftsmen. This hand-winding Vulcain’s proprietary mechanism with an alarm (duration of 20 seconds) features a high grade finish, 18 jewels and 157 parts, has a power-reserve of 42 hours and oscillates with 18,000 vibrations per hour.
It incorporates a double barrel, equipped with the brand’s patented Exactomatic system which provides higher precision and stability by equalizing the friction on the balance-wheel axis in all positions and ensuring more steady amplitude. The Cricket caliber is famous as the world’s first wristwatch alarm mechanism, created in 1947.
Elegance and Luxury
A 42 mm case is crafted in 18K 5N rose gold. A mid-size diameter with the thickness of 12.7mm seams like the perfect size for an average man’s wrist. A beautiful polished bezel emphasizes a deep, skeleton dial with a silver-toned rim. Blue, hand-applied hour indices and Arabic numerals, as well as blue, skeletonized hour and minute hands give it an outstanding visual effect, making this watch a true piece of art. This watch also has a blue second hand and forth, alarm hand with a skeletonized arrow on top.
