Brand: Porsche Design Model: Chronograph 7176S Movement: Lemania 5100 automatic Case: Bead-blasted stainless steel Size: ~42mm For sale is my Porsche Design 7176S, one of the classic tool chronographs designed by Ferdinand Alexander Porsche and powered by the legendary Lemania 5100. This is a true purpose-built chronograph with central minutes, day/date, and tank-like reliability. The watch has been recently serviced (happy to share details with serious buyers) and is running well. Bead-blasted case is in honest, worn condition consistent with age — no over-polishing, just the right amount of character for this reference. Crystal is clean, chronograph functions reset properly, and day/date changes correctly. This is a birth-year–era piece for me and an incredibly cool, historically important watch, but I’m consolidating my collection and letting go of pieces that no longer fit my core rotation. Why this watch: If you’re into utilitarian chronographs, aviation history, or the Lemania 5100 specifically, this is one of the references to own. Lightweight on the wrist, incredibly legible, and unapologetically functional.
