Catalogue description

Dealer description — Craft & Tailored

Heuer manufactured LeJour chronographs under a private-label arrangement in the 1980s. Under the terms of the arrangement, Heuer manufactured an array of watches which LeJour then distributed. Some, like the Heuer Pasadena and LeJour model 7750, used the exact same cases. If this watch looks familiar to you, it's with good reason - LT Pete "Maverick" Mitchell, played by Tom Cruise in the hit movie "Top Gun", wears a very similar example made by Orfina and branded under Porsche design. Both the Heuer and the other references, like this LeJour, used the Day-Date Chronograph Valjoux 7750, which is how it got its reference name. Orfina produced some of these references in stainless steel, but most of the sub-branded manufacturers chose to stick with the early black PVD steel case. SPECS Stock # LJCHRON7-7 Brand LeJour Style Chronograph Model 7750 Serial N/A Size Men's Material Stainless Steel W/ Factory PVD Finish Dial Matte Black Millimeters 40 Bracelet LeJour Bracelet W/ Factory PVD Finish CASE & BRACELET The unpolished case features its original factory PVD finish, featuring crisp edges throughout. The only notable element of age of the case is some subtle greying to the finish on the edges, which is commonly found on early PVD cases. The original mineral glass crystal does show wear and scratches. The case retains its original PVD-finished pump pushers and unsigned crown. The original LeJour bracelet does exhibit some loss of the factory PVD finishing, mostly on the underside of the individual links, and retains 14 links that show minor stretch and will fit up to a 7.25-inch wrist. DIAL & HANDS The matte black dial is in excellent condition, with the only notable element of age being some tonal marks near the center of the handstack that are only visible under magnification. The tritium lume plots have achieved a deep beige patina, under UV light inspection, the 5 o'clock plot features minor degradation, while all the others remain fully intact. The original tritium hands have aged a few shades lighter than the dial, and show no degradation when inspected under UV light. ACCESSORIES The watch comes as a complete set with its original inner and outer boxes, instruction booklets, and sales tags. The watch is running and keeping time, previous service history is unknown,

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide

Chronographs and split-seconds watches

A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.

Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.

What to look for

  • Push-pieces on the case band or a single button in the crown (monopusher).
  • Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
  • Column wheel versus cam control visible in the movement.
  • Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).

Dating clues

  • Pocket chronographs with heart cam reset: after 1862.
  • Wrist chronographs: from c. 1910; two-button designs from the 1930s.
  • Automatic chronographs: from 1969.
