The legendary original Bertucci® titanium performance field watch...

Introduced in 2004, the A-2T Original Classic™ was an immediate success… striking the perfect balance between tradition and innovation, making it the industry leading field watch. The rugged U.S. Patented Unibody™ 40 mm case is made from titanium… a high performance alloy we believe to be the best material for a field watch as it provides lightweight comfort, unmatched durability & corrosion resistance. A watch that is ready for the rigors of the day… whatever they be.
