Design
- Case and Dial
- The watch is housed in a 40mm stainless steel case that features a factory-applied black PVD finish. The chronograph pushers retain their original coating, while the crown exhibits visible wear to the PVD finish from regular use. The dial is finished in a matte black tone, featuring hour markers treated with tritium luminous material, which has aged to a beige, sandy color. Complementing the hour markers are tritium-filled hands, while the chronograph seconds hand is finished in a neon orange color for contrast. A day and date display is integrated into the dial at the three o'clock position.

- Movement and Functionality
- The watch is driven by the Valjoux 7750, a widely utilized Swiss-made automatic chronograph movement. The movement provides standard timekeeping and chronograph functions. The screw-down case back is inscribed with details regarding its mechanical features, including shock resistance (Incabloc), anti-magnetic properties, and water resistance, although detailed technical specifications for the movement are not provided in the source documentation. While the auction description reports that the watch remains operational and holds time, there is no documented record of previous service intervals. The watch is presented without any original packaging or accompanying manufacturer papers.
- Provenance and Attribution
- This specific timepiece is noted for its provenance as part of the personal collection of Magnus Walker, a designer known for his automotive work. The SC-Turbo Design name links the watch to the Porsche 911 model line, specifically the SC and Turbo variants, aligning the aesthetic of the piece with 1980s automotive themes. The bracelet currently fitted to the watch head is a later-period Porsche Design steel bracelet with a PVD coating, differing from the original configuration of the watch head itself. The attribution of the watch's origin as Swiss is supported by markings located on the dial and the case back.
