The Excalibur Bi-Retrograde Calendar by Roger Dubuis

This year, Roger Dubuis celebrates its 30th anniversary, and for the occasion, the company pays tribute to its co-founder’s favourite complication: the bi-retrograde display.

This function, previously featured in the Excalibur Grande Complication alongside a dozen other highly complex mechanisms, takes centre stage once again. The Maison has also introduced a less complicated, more classic edition to further honour the bi-retrograde display.

Also referred to as “the ecliptic counters” by the Maison a nod to their elliptical shape and distinctive role in indicating the months and date the design showcases a symmetrical dial layout. Enhanced by refined detailing, it pays homage to the Maison’s early creations from 1996.

Light-Emitting Diode (LED)

Light-Emitting Diode (LED)

A small electronic device that emits light when an electric current passes through it. Light-Emitting Diodes (LEDs) are commonly used as a source of illumination for watch display screens. LED technology offers several advantages, including low power consumption, long lifespan, and the ability to produce bright and consistent light.

LED screens are typically used in digital or electronic watches, where the time and other functions are displayed digitally on the screen. The LEDs behind the screen illuminate the numbers, letters, or symbols, allowing them to be easily read in various lighting conditions. Watches equipped with this technology often have a button or crown that activates the backlight, enabling the wearer to view the time even in low-light or dark environments.

LED technology has evolved over the years, and modern LED watches may incorporate advanced features such as multiple color options for the backlight or even animations. LED displays have become popular due to their readability and energy efficiency, making them a common choice for digital watches and other electronic devices.
