The Rolex GMT-Master Chronometer
As told masterfully by Charlie Dunne, "There’s no other watch like the Rolex GMT-Master reference 1675. 1675s are incomparable to any other watch as the variety of dials and beautiful bezels can be profoundly different across years of production and manner in which they have aged over time.  No other Rolex has the distinguishable bezel like a “Pepsi”, and the 1675 has the longest production duration for any Rolex GMT-Master."
 
"Rolex introduced the GMT-Master in circa 1959 and the reference remained in production until circa 1980.  This two-decade period represents a significant portion of the Rolex’s history and is recognized by most watch collectors as the golden era of vintage-sports watches from any manufacturer."
 
"The story for the GMT-Master begins when Pan American Airways (Pan Am) and another world-renowned aviation company purportedly commissioned Rolex to create a wristwatch suitable for their pilots: one that allowed them to efficiently tell two time zones simultaneously.  Pan Am cites their President Juan Trippe had approached Rolex to create a watch for the airline pilots which resulted in the reference 6542." 
 
"Throughout the 1950s to 1970s, Pan Am was regarded as a preeminent airline and became one of the largest international air carriers. T he company took pride in equipping their pilots with the best amenities - the GMT-Master being one of them! Rolex was thrilled to highlight this relationship with Pan Am in marketing materials.  It is akin to the way Rolex highlights their relationships with events such as the PGA Championship, Wimbledon, and the Academy Awards.  As you can see later in the article, the manufacturer showcased this relationship within advertisements and catalogs for many years."
 
The Concorde Airframe
The Concorde is a retired Anglo-French supersonic airliner jointly developed and manufactured by Sud Aviation (later Aérospatiale) and the British Aircraft Corporation (BAC).  Studies started in 1954, and France and the United Kingdom signed a treaty establishing the development project in late 1962, as the program cost was estimated at £70 million (£1.68 billion in 2023).  Construction of six prototypes began in February 1965, and the first flight took off from Toulouse on in early 1969.
 
The market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines.  In October 1975, the Concorde received its French Certificate of Airworthiness, and from the UK CAA in December.
 
The Concorde is a tailless aircraft design with a narrow fuselage permitting 4-abreast seating for 92 to 128 passengers, and a droop nose for landing visibility.  It is powered by four Rolls-Royce/Snecma Olympus 593 turbojets for take-off and acceleration to supersonic speed.  Constructed of aluminum, it was the first airliner to have analogue fly-by-wire flight controls.  The airliner had transatlantic range while supercruising at twice the speed of sound for 75% of the distance.
 
Delays and cost overruns increased program cost to £1.5–2.1 billion in 1976, (£11–16 billion in 2023), but the Concorde entered service in late January 1976 with Air France and British Airways, with transatlantic flights as the main market.  Air France and British Airways remained the sole customers with seven airframes each, for a total production of twenty. Supersonic flight more than halved travel times, but sonic booms over the ground limited it to transoceanic flights only.
 
On 25 July 2000, Air France Flight 4590 crashed shortly after take-off with all 109 occupants and four on the ground killed.  This was the only fatal incident involving Concorde; regardless, commercial service was suspended until November 2001.  The surviving aircraft were retired in 2003, 27 years after commercial operations had begun, and all but two of the 20 aircraft built have been preserved and are on display across Europe and North America.
