Porsche Design by Orfina Chronograph 1 (Lemania 5100 variant)

This is an iconic Porsche Design by Orfina Chronograph 1, an historically significant timepiece that revolutionized watch aesthetics in the 1970s. The watch features a bead-blasted stainless steel case with a matte grey finish, originally intended to be non-reflective for functional utility. Its distinctive black dial is highly legible, featuring a three-register layout with white index markers and hands. A notable detail is the central orange/red chronograph seconds hand, providing high contrast against the dark background. The dial prominently displays the 'pd' interlocking logo at 12 o'clock and 'PORSCHE DESIGN' text alongside the day-date aperture at 3 o'clock. This specific model likely houses the Lemania 5100 automatic movement, identifiable by the layout of the sub-dials. The watch is fitted on its original-style integrated multi-link steel bracelet with a folding clasp. Regarding condition, the piece shows moderate vintage wear consistent with age, including surface scuffs on the bezel, case edges, and bracelet links. The crystal appears clear with no major cracks. This model represents the collaboration between Ferdinand Alexander Porsche and the Swiss watchmaker Orfina, typically dating from the late 1970s to the early 1980s. The craftsmanship is professional-grade, reflecting its heritage as a military-issued timepiece used by various air forces.
