Period
1970s
This Porsche Design by Orfina Chronograph 1, reference 7176D, is a vintage wristwatch dating to the 1970s. The watch features a 40mm sandblasted steel case paired with a matching matte three-row steel bracelet.
It is powered by the Lemania 5100 movement. The black dial contains three chronograph sub-dials, an internal tachymeter scale, and day-date windows displaying text in German. The hour markers and hands include tritium material, which has developed a yellow patina. A prominent orange central chronograph seconds hand provides a high-contrast detail against the dark dial. This specific example has undergone mechanical servicing.

Design
- Case and Dial
- The watch is housed in a 40mm steel case characterized by a grey sandblasted finish. The construction includes a semi-integrated bracelet that transitions directly into the case profile, maintaining a matte texture consistent with the watch head. The lugs are defined by sharp edges. The black dial is arranged with three sub-dials for chronograph tracking. An internal tachymeter bezel is positioned on the periphery of the dial. The day and date indicators utilize German-language wheels. The indices and hands feature tritium lume that has patinated to a yellow tone, contrasting with the orange central chronograph seconds hand.
- Visible features
- • Case and bracelet possess a uniform sandblasted finish • Day and date wheels appear in German (e.g., 'SON', 'SAM') • Tritium indices show age-related yellow discoloration • Internal bezel features a printed tachymeter scale
- Signatures and Branding
- The branding reflects a collaboration between the Porsche Design studio and the watchmaker Orfina. The dial features the 'Porsche Design' wordmark. The bracelet is fitted with the PD-signed clasp, identifying the components as specific to the model family. The watch is linked to the 1970s period through its serial number sequence. The design reflects the visual language established during the initial development of the Chronograph 1 model under the guidance of Ferdinand Porsche.
- Movement and Functionality
- The watch operates using the Lemania 5100 chronograph movement. This automatic caliber drives the hour, minute, and central chronograph seconds functions, alongside the day and date display. The auction description notes that the movement has been serviced to ensure current functionality. Mechanical operation is controlled through the crown and lateral pushers. The internal bezel serves a tachymetric function for speed calculation, integrated within the main dial assembly rather than the exterior case, which is consistent with the model's design specifications.
