Overview
The A-13S Diver's Watch
I'm currently building my own personal dive watch—one that reflects exactly what I believe a true tool watch should be.
It's a personal project, driven by passion rather than plans. If everything goes as hoped, and if I'm completely satisfied with the result, who knows...
There might even be a third A-13A one day.
