Somewhat of an anniversary piece - 40 years of Nauitluses (Nautili??), 20 years since the invention of the annual calendar, and 20 years in my job....
Any excuse eh ? 🙄
Poor lighting, but fresh arrival on the wrist.
Lemania ch13 (aka Omega 28.9 Chrono).
Early 1930s solid silver case chronograph.
Fixed lugs makes for temporary NATO strap solution. 😀😀😀
