tachymeter

Today's updated design features a brown polished ceramic bezel ring and a matt chromium nitride tachymeter scale, as well as brown PVD subdials and a central opaline silvery dial.

The design of the new watch evokes motorsports with Tachymeter markings on the bezel and an in-dial at the 4 o'clock position with a multidimensional design inspired by the speedometer of a sports car.

The dial features a white tachymeter scale on a black inner bezel around the dial, with a red tachymeter inscription.

Flip it back to the dial side and you'll see the hours, minutes, seconds, perpetual calendar, large date, moon phase, flyback chrono with a tachymeter scale and a power reserve indicator all arranged brilliantly on that striking pink gold dial.

Its bi-compax dial with a small seconds counter at 9 o'clock and a chronograph 30-minute counter at 3 o'clock, as well as a tachymeter scale on the outer part of the dial recall the glory days of Minerva's chronograph production.

A cornerstone of the brand since 1963, this avant-garde chronograph, forever associated with motor racing, wears its DNA with sporting pride and now features a brand new engine in its newest reincarnation as the TAG Heuer Carrera Heuer 02 - the new Heuer 02 Calibre manufacture movement - along with a 43 mm modular case, a tachymeter bezel, and a skeleton dial with 3-6-9 counters.

For later evaluation, the user carried a prism mounted next to the receiver antenna that was tracked by a tachymeter (Leica Geosystems TCRP1200) to obtain the ground truth of the user location in centimeter accuracy.

The tachymeter scale transforms the chronograph into a powerful racing instrument.

Although a modern Rolex Cosmograph Daytona costs $12,400 today, the models of the '60s and '70s cost about $250 and were little more than timekeepers for gear heads, featuring a built-in stopwatch for timing laps and a tachymeter for calculating speed.

Along with the flyback chronograph, lap timer and electronic tachymeter, the B55 "Racing" calibre provides three different features.

The signature tachymeter scale also satisfies even the most exacting demands.

The second in the sweet and sensual new threesome is the Limited Edition Rado HyperChrome Automatic Chronograph Tachymeter. Here Rado's designers have taken the liberty to contrast the matt brown high-tech ceramic case with a polished rich brown bezel engraved with a tachometric scale and filled with white Super-Luminova.
