Patek Philippe Multi-Scale Chronograph Refs. 5975 and 4675
Chronographs for measuring time intervals are among Patek Philippe's most popular timepieces. With eight regularly produced chronograph calibers, all of them developed and crafted entirely in-house, the manufacture's portfolio in this category is delightfully diversified as regards functionality and aesthetic appeal. A special model was created to commemorate the 175th anniversary; it has a few capabilities more than ordinary chronographs.
No type of watch reveals its purpose as a measuring instrument as obviously as the chronograph. If its function is combined with suitable scales, it can even transform itself into a mechanical computer for the wrist and will execute calculations based on time measurement. Accordingly, the commemorative model – the Multi-Scale Chronograph – is endowed with three logarithmic scales that can be used to compute speeds, distances, and heartbeats per minute. Until well into the 1960s, watches with tachymeters, telemeters, and pulsimeters were commonplace and widely used by professionals. This is what makes the limited-edition Patek Philippe Multi-Scale Chronograph for ladies and men such an attractive homage to the history of the manufacture and of time measurement.
