Catalogue description
Dealer description — Craft & Tailored
Founded more than 150 years ago, the International Watch Company has grown to become one of the most recognizable Swiss watch brands on the planet. And one of the things they're especially famous for is their caliber 85 movement, which is widely regarded as one of the finest watch movements ever made. The cal. 85 was introduced in the 1950s and was the second automatic movement the brand ever made – it was also their first automatic movement with central seconds. That movement went on to birth multiple subsequent versions, including the cal. 852, 853, 854, and finally the 8541B. The cal. 854 (or 8541) in-house movement found in this ref. 817A was initially introduced in 1964 and received widespread recognition when IWC utilized it in their premier Ingenieur line of watches. But the movement was also used in a wide variety of different offerings from the IWC brand, thanks to its robust design and reliability. This particular IWC in stainless steel is simply stunning with a no-nonsense design. The dressy Calatrava case and dial design pair excellently with the utilitarian stainless steel material. This watch makes for a highly reliable daily wearer, which is designed to last.

Historical context
Modern Mechanical Horology (1945 – 1969)
Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide
Automatic (self-winding) watches
Self-winding watches use the wearer's motion to wind the mainspring. Abraham-Louis Perrelet and Breguet made 'perpétuelle' pocket watches with oscillating weights in the late eighteenth century, but the principle only became practical in the wristwatch. John Harwood patented a bumper automatic in 1923; Rolex's Perpetual rotor (1931) winding in one direction, and later bidirectional rotors (Eterna, Felsa Bidynator), established the modern form. Micro-rotors (Universal Genève, Buren) and peripheral rotors made automatic watches thinner.
What to look for
- A semicircular rotor turning 360° over the movement, or a 'bumper' weight that rebounds between springs.
- 'Automatic', 'Perpetual' or 'Self-winding' on the dial.
- A sealed screw-back case, since automatic watches are wound less often by the crown.
Dating clues
- Bumper automatics: 1923–c. 1955.
- Full rotors: from 1931 (Rolex); widespread after c. 1950.
- Micro-rotors: from 1954–1958.
