Chronoswiss Chronoscope

Introduced in 2001, the Chronoswiss Chronoscope is the first Wristwatch Chronograph with Regulator Dial and window for the blued column wheel.

For the “Chronoscope,” which recalls the pioneering achievements of watchmakers of the past century, Chronoswiss mounted the complex cadrature, which was developed in collaboration with  Andreas Strehler, directly atop the front side of the plate of the exclusive self-winding manufactory caliber C.122, which is also known as the “Regulateur.”

This is precisely where the cadrature was originally mounted by chronograph pioneer Adolphe Nicole. Unlike common and widely used modular constructions, which typically require no alterations to the plate, Chronoswiss specially reworked the plate to accommodate the frontally mounted cadrature. For example, indentations are specially milled and holes drilled to accept the components of the elaborate switching movement.

The three functions (start, stop, and return to zero) of the centrally axial chronograph-hand are triggered via a push-piece that’s integrated into the winding-crown and are controlled internally via a classical column-wheel which rotates around the arbor of the continuously running seconds-hand on the sub-dial above the “6.” The chronograph’s ball-borne center-wheel, on the other hand, is a genuine homage to modernity and an entirely unprecedented construction.

Of course, it goes without saying that all of the components, of which there are a total of 38, are specially made by Swiss specialists expressly for Chronoswiss.

The positioning of the hour-hand on its own sub-dial below the “12” is a typical feature of timepieces that encase the Regulateur movement. For readily understandable reasons, Chronoswiss has made no changes in the self-winding C.122 movement, which is already constructed in accord with all of the exacting rules observed by the watchmaker’s guild and which, in its version for the “Chronoscope,” goes by the name “C.125.”

Its Glucydur balance, which is equipped with a self-compensating flat balance-spring, completes 21,600 beats per hour, thus enabling the “Chronoscope” to measure intervals of time with sixth-of-a-second accuracy.

The Regulator-dial boasts a window that allows insight into the blued column wheel.
