Product Description

Designed with functionality for pilots and navigators in mind, this navigation chronograph features a distinctive dark blue dial and a display case back that offers a view of the self-winding movement within. Its purposeful design and practical layout reflect the character of a professional instrument watch.

The watch shows light signs of wear, including minor surface marks and light scratches, but there are no noticeable deep scratches. In February 2026, it underwent manufacturer-authorized service, including calendar repair as well as internal inspection and adjustment.

All watches offered by BIG MOON are carefully inspected by our professional watchmakers and guaranteed to be 100% authentic.

Before the purchase is finalized, we will contact you directly by email with detailed information regarding the condition of the watch. We kindly ask that you review our message carefully before proceeding with the purchase.
