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 and movements. An instantly recognizable example of this day-date chronograph can be seen on the wrist of LT Pete "Maverick" Mitchell played by Tom Cruise in the hit movie "Top Gun" who is wearing a PVD-finish example made by Orfina and branded under Porsche design. The Heuer and the other references like the LeJour 7750 used the Day-Date Chronograph Valjoux 7750 movement, which is one of the most respected movements with its many complications in a relatively compact package, and is also how the LeJour got its reference name. Each brand produced these references with stainless steel in two case finishes, the bead-blasted anti-reflective stainless steel and a black PVD variant which is the one seen on Maverick's wrist in Top Gun. Though it is far more common to see the sub-brand variants in the PVD finish than the bead-blasted stainless steel option. The case size is 40mm in diameter with a screw-down case back, mineral crystal, Internal tachymeter bezel, black dial with tritium luminous indexes, day, and date at the 3 o’clock position of the dial.

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.
