U-Boat Classico AB 4 & the Original Carbonio ¶
The "Carbonio" was introduced by U-Boat watches years ago as part of the Classico Automatic Series. For the first year or so, it was a considerable success, and had built up a strong following. Then for reasons unknown to me the Carbon fiber-clad watch was discontinued, making it very difficult and sometimes impossible to obtain for our clients. Finally, the watch is once again available. Because it is produced in smaller quantities then other Classico models, and is the only Classico to offer a dial made entirely of carbon fiber, it will continue to make an important impression on enthusiasts of U-Boat watches.
What makes the Classico AB 4 the "Carbonio" is its carbon fiber dial. It is made entirely out of genuine carbon fiber and contrasted sharply by its bold, white hour markers and hands. Carbon fiber is used often for its light weight and strength, but on the Carbonio it is its stylish qualities that prevail. The Carbonio conjures visions of powerful concept sports cars and automotive racing.
The Classico AB 4 Carbonio is available in a 45 or 53 mm case. The case is of stainless steel and is blackened via the PVD process. The shape of the sturdy case is the same as those used for the basic Classico AS 1 and Classico AS 2. It is equipped with a thick sapphire crystal and a black rubber strap. The movement is the Swiss made automatic 2824 calibre, which is a definite winner when it comes to quality and reliability. A see-through back makes it possible to admire the mechanism.
