A matter of adjustment

For an IWC watch to run accurately, the oscillations of the balance require careful adjustment.

Balance of power

A mechanical watch continues to show the correct time even as the tension in the mainspring diminishes. Making this possible is a mechanism that has been gradually improved for over 300 years: the escapement.

Cal. 87

Date — 28 September, 2011

Share:

Of the many legendary hand-wound movements made by IWC, the 87 calibre holds a very special place.

This is because it was the first tonneau-shaped wristwatch movement that could be fitted into both rectangular and tonneau-shaped wristwatch cases, which were very much en vogue in the 1930s. With its screw balance and Breguet spring – but minus a shock-absorption system – it was extremely accurate and showed the precise time on a small seconds and the hour and minute hands. Altogether, 18,400 of them were produced between 1931 and 1947. Today, IWC watches with the 87 calibre are much-coveted collector’s items.

  • Dimensions: 20 × 25 mm
  • Height: 3.65 mm
  • Frequency: 18,000 bph (2.5 Hz)
  • Number of jewels: 15, 16 and 17

A SIMPLE, TIMELESSLY ELEGANT WATCH COMBINING OUTSTANDING DESIGN AND FUNCTIONALITY.
