Tachymeter and Telemeter: The Measuring Aesthetics of LEBOIS

Chronograph lovers will unconsciously notice the "Tachymeter" and "Telemeter" scales engraved on the bezel and the outer periphery of the dial. These are not merely decorative, but practical instruments that once served as "precision instruments" to expand human perception. The two scales featured in LEBOIS chronographs, along with their authentic design, embody the aesthetics of measurement in the history of watches.

Tachymeter: A tool for reading speed from time

A tachymeter is a scale that reads speed from the time it takes to cover 1 km (or 1 mile). If you start the chronograph's second hand and stop it the moment you complete the distance, the number on the outer periphery that the hand points to will indicate your average speed.

Although it appears simple at first glance, the design philosophy is actually profound. A tachymeter can only measure events of up to 60 seconds . In other words, it is based on the premise of a "speed range that can be tracked by human senses," and objects that can cover 1000 meters in under one minute were the very symbols of 20th century modernity, such as automobiles, trains, and airplanes. The LEBOIS tachymeter scale condenses this "20th century rationality that directly links speed and time" onto the dial.

Telemeter: A device that measures distance using the difference between light and sound

On the other hand, telemetry calculates distance rather than speed. The mechanism is straight out of a physics textbook. By taking advantage of the difference in the speeds of light and sound, the distance to a phenomenon can be calculated by measuring the time lag between seeing light and hearing sound, such as thunder or artillery fire.

The chronograph second hand starts at the moment of lightning and stops at the moment of thunder. The telemeter scale indicated by the hand allows direct reading of the distance to the thundercloud. This is the "practical science" utilized on the battlefield and in nature observation in the first half of the 20th century, scaled down to the size of a wristwatch. The LEBOIS model, with its delicate scale, gives the feeling of peering into the field of vision of a battlefield officer or weather observer.

LEBOIS-style aesthetics

Both scales are also found in chronographs from other brands. However, what's interesting about LEBOIS' interpretation is that the design is not overly exaggerated, and the functionality remains clearly visible in the "usable" face. The vintage-inspired font, exquisite peripheral layout, and the well-balanced use of white space combine visibility as an instrument with a classic aesthetic.

In other words, LEBOIS chronographs preserve the aesthetics of functions like "speed calculation" and "distance calculation," which are rarely used in modern times, while also possessing a realism that makes you want to actually try them out. The playfulness of measuring the distance of thunder, or experimenting with calculating the speed of an old car - the LEBOIS chronograph philosophy allows for these things.
