As one of the original launch watches in 2007, the ALT1-Z has been around since the beginning. It is one of the major models used for military squadron watches, and the retail version remains popular to this day. While the original ALT1-Z will remain in the collection, the ALT1-ZT serves as a slightly edgier refresh to the classic Z layout. I love the way this one turned out, especially with the handset, the applied markers, and the elevated subdials. Well done!
