Catalogue description

Dealer description — Analog/Shift

Simple. Refined. Understated. When choosing a good dress watch, one should be conscious of it's role: A dress watch should not leap from the wrist, declaring its presence obnoxiously to onlookers. It should be a subtle companion that accents the wearer and his outfit. Ideally a precious metal, a dress watch should also be simple and clean, without the noise of chronograph or other functions. While the International Watch Company is often associated with their lovely Portuguese chronographs, sturdy Aquatimer divers, Big Pilot aviators, or their 70's inspired Ingenieur SLs, it has also been a longstanding manufacture of some of the most beautiful dress watches we can think of. With a solid 18K yellow gold cushion case, this IWC Schaffhausen fits the bill for wrist attire in any setting where a little class goes a long way. As with many of IWC's watches, the true beauty of the timepiece is on the inside. In this case, the mechanical genius comes in the form of the Calibre 8541B automatic movement, long considered one of IWC's best engineered movements. Easy to service and incredibly accurate, it is also compact enough to make this a relatively slim-wearing watch for the era, measuring in at only 11.2mm from case back to crystal. This particular example dates to the 1970s and is in remarkable original condition. The 36mm cushion case retains crisp lines and brushing and is perfectly accented by the clean gold tone sunburst dial and hands. Paired with a Horween Shell Cordovan strap with matching gold hardware, this IWC is ready for formal wear. And, with the added benefit of a date function, this piece would make an extraordinary everyday dress or business piece. Whatever the use, there is no denying that this IWC's classic stylings and robust movement make it a lovely and desirable piece.

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

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.
