The Porsche Design Chronograph 1, reference 7176S, stands as a landmark in horological history, being the first all-black chronograph and a defining icon of 1970s design. Introduced in 1972, this model captured the era’s fascination with technical innovation and motorsport heritage, and remains highly sought after by collectors for its pioneering use of PVD coating and its unmistakable, purpose-driven aesthetic.
This example presents the classic matte black dial, its surface retaining a deep, even tone that beautifully offsets the crisp white printing of the signature Porsche Design logo and the distinctive day-date display at 3 o’clock. The luminous hands and hour markers have aged gracefully, showing a subtle, even patina that speaks to the watch’s vintage character without compromising legibility. The original tachymeter bezel, also finished in black, frames the dial with minimal signs of wear, its numerals still sharp and fully legible. The stainless steel case, coated in the original PVD, displays honest wear consistent with age, with the coating largely intact and only minor edge wear visible—testament to careful use over the decades. The crystal and crown were replaced during a comprehensive movement overhaul by Superior Watch Services in October 2020. The pushers remain original and function with satisfying precision. The caseback, is showing two deep scratches around the 3 o'clock mark. Inside, the legendary Lemania 5100 movement—renowned for its robustness and central minute counter—runs smoothly following its recent professional service.
This Chronograph 1 offers collectors a rare opportunity to acquire a foundational piece of modern chronograph design. Its combination of historical significance, honest vintage character, and recent professional attention make it a compelling addition to any serious collection.

Good luck to the bidders, you'll enjoy this watch!
Re: colston Ok thanks. Tape measure might be tough to get the right measurement and that spring loaded slide clasp can uncoil quick so no need. Thank you.
Re: Crw I have fairly slim wrists, I'll see if I have a tape measurer around here to get an exact measurement. I wear the watch with three expansion holes available on the clasp.
What size wrist does the bracelet fit up to without the strech clasp expanding?
Glad to see there is some love for my Porsche Design. I've had this watch since 2017, and have really enjoyed having it. Whoever ends up with it will be really pleased. The hands and dial have aged to a very rich yellow/orange.
