The three-quarter plate: a style hallmark for A. Lange & Söhne

15 Апрель 2018 | , ,

Ferdinand Adolph Lange was a perfectionist watchmaker, seeking for the optimum engineering solutions for its watches. This is the reason why he worked on the evolution of the many separate bridges and cocks commonly used to assembly the movement of a watch. For the watchmaker it was a quite hard work, made of trials and…

How does a watch work: plate, bridges and jewels as a support for gearwheel

9 Май 2015 | ,

A watch mechanism works thanks to wheels’ and pignons’ motion, transmitting energy from the barrel to the balance-wheel. But how do those wheels stand? Let’s learn about watchmaking with an easy watch glossary. A watch mechanism is assembled on a plate: a flat piece of metal, usually made of brass, that serves as a foundation…

Watchmaking storytelling:Silicon, the greatest innovation in watchmaking?

13 Октябрь 2014 | ,

It is the second element most common in Nature, after oxygen. It forms almost 30% of Earth’s crustal plate weight. It is commonly used in bricks production, in solar panels and in microelectronics. Since a decade, it is the frontier of innovation also in watchmaking. For hairsprings and wheels. We are talking about silicon. This…

Watchmaking storytelling: perpetual calendar watches

28 Август 2014 | ,

Gregorius XIII conceived on 1582 the Gregorian Calendar, the same calendar sill regulating our time. At that time, he did not reflected on the issues he would have created to watchmakers in the following centuries… It was the XVI century when time measurement with a portable and adequately precise instrument became possible, but only at…

Virtuosity on seconds hand: complicating the essential

24 Май 2014 | , , , ,

The seconds hand is fundamental in watches, especially in the automatic ones, since it indicates the flow of time, and shows the correct functioning of the watch. In mechanical watches, the seconds’ hand is naturally decentrated, because it is placed on the second’ wheel. By modifying the wheel train, thus adding a complication to the…

Innovation and watchmaking: photovoltaic tests in the 1950s

20 Март 2014 | , ,

Many innovations were introduced in Basel Fair on 1953. The most interesting was a revolutionary clock, the Pendulette Solaire, that proposed Patek Philippe as an historical Maison able to face the challenges of technological evolution. The innovation beyond the Pendulette Solarie was patented as “Énergie photoélectrique”. Where does this clock come from? Watchmakers always looked…

How do blue screws, tipical feature of high watchmaking, are made?

4 Ноябрь 2013 | ,

Burnished steel components, screws particularly, are used in watchmaking industry for their higer resi stance to corrosion, beyond being far more elegant in their periwinkle blue. How is this colour obtained? Material is heated, generating a thin oxide layer. The highest is the temperature, the thicker is the oxide layer. The thickness of the layer…
