Phantom SL Avantgarde


The all-new Phantom SL Avantgarde is the world's most lightweight mechanical-winding, professional-grade tool watch. Its sleek Soarway case is made from lightweight aerospace-grade titanium with a polished finish. A further weight reduction is achieved by skeletonizing the chronograph movement that powers the Phantom SL Avantgarde.

"SL" stands for SuperLight. The Phantom SL Avantgarde is so light, in fact, that after you put this toolwatch on your wrist, after a few moments you barely know it's there anymore.

For collectors, the Phantom SL Avantgarde features a skeletonized dial and a sapphire crystal exhibition back, which allow a direct view into the watch's skeleton movement. This watch is limited to only 50 pieces.

The Phantom SL Avantgarde arrives on a natural rubber strap and ships with a separate alligator strap. A polished titanium bracelet is optional.

The watch is covered by a 10-year warranty against material defects and inferior workmanship.

Designed, engineered, fabricated, assembled and tested in the United States from U.S. and imported components.

*** The Phantom SL Avantgarde ships in spring 2022. Customers who wish to reserve one of these watches will receive a Phantom Chronograph loaner watch until the Phantom SL Avantgarde is ready to ship. ***
