Porsche Design by Orfina Chronograph Ref. 7750

Partially verified

This Porsche Design chronograph is a 1980s wristwatch manufactured by Orfina. The watch features a 40mm bead-blasted stainless steel case with an internal tachymeter bezel and a mineral crystal. It is powered by an automatic Valjoux 7750 day-date chronograph movement. The matte black dial displays tritium luminous indices that have aged to a dark pumpkin tone, accompanied by matching hands. The watch is presented on its original stainless steel link bracelet. The construction includes a screw-down case back and pump-style pushers. The auction description notes the case retains its original antireflective brushed finish, with only a minor polish applied to the top of the bezel. This stainless steel variant is distinguished from the black PVD coated versions produced by the same partnership during this era.

Object description

Case and Bracelet

The watch is housed in a 40mm stainless steel case featuring a bead-blasted, anti-reflective brushed finish. The design incorporates a screw-down case back, which the auction description reports retains its original factory engravings, and a mineral glass crystal that exhibits minor wear and faint scratches. The case is fitted with original pump-style pushers and a crown bearing the Porsche Design logo.

The timepiece is attached to its original stainless steel bracelet, which comprises 24 links. The auction description states that the bracelet shows almost no stretch and is capable of fitting a wrist up to 7 1/2 inches in circumference. The exterior finish of the case is described as largely original, though a slight polish has been applied to the top edge of the bezel near the crystal.

Evidence for this section
  • “featuring a 40mm case with a screw-down case back, mineral crystal”
  • “The case is in excellent condition and mostly retains its antireflective brushed finishing”
  • “The watch comes supplied with its original Porsche Design stainless steel bracelet”

Dial and Movement

The matte black dial includes an internal tachymeter bezel and indices treated with tritium luminous material. These luminous elements have developed a dark pumpkin-colored patina. A day-date complication is positioned at the 3 o'clock mark. The chronograph functions are arranged in a layout facilitated by the internal movement.

Internally, the watch is powered by a Valjoux 7750 automatic movement. This caliber provides both chronograph timing functions and a day-date display. The movement is specified as the automatic day-date chronograph Valjoux 7750, a central component of the Porsche Design by Orfina series during the 1970s and 1980s.

Evidence for this section
  • “black dial with tritium luminous indexes”
  • “dial and hand lume that have aged to a vintage-perfect dark pumpkin coloration”
  • “The watches utilized the automatic day-date chronograph Valjoux 7750 movement”

Provenance and Attribution

The watch originates from the partnership established between Porsche Design and the manufacturer Orfina. Following the founding of Porsche Design in 1972, Orfina was selected as the exclusive manufacturer for their early watch production. This collaboration spanned from the early 1970s into the 1980s.

The reference 7750 is documented as a stainless steel variant within the Porsche Design by Orfina series. The auction description notes that this particular model represents an alternative to the black PVD-coated versions that became widely associated with the brand, most notably through film appearances such as in the motion picture 'Top Gun'.

Evidence for this section
  • “When Porsche Design first opened its doors in 1972 and started producing watches, they chose Orfina to be their partner and manufacturer.”
  • “Orfina produced these references in stainless steel with two finishes.”

Open research questions

  • What specific production year is associated with this particular serial number range for the Ref. 7750?
  • Are there records detailing the specific batch numbers for the non-PVD stainless steel variant of this chronograph?
