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.

sandblasted

Sandblasting, is a surface treatment technique that involves propelling abrasive particles at high speed onto a material's surface. In the context of watchmaking, tiny particles such as sand or garnet are propelled onto the watch case using compressed air or a specialized sandblasting machine. This process creates a textured, matte finish on the metal surface, resulting in a distinctive appearance.

The Benefits of Sandblasted Technology:
Sandblasted technology offers several benefits that have made it a popular choice among watch manufacturers and enthusiasts alike:

Unique Aesthetic: The sandblasted finish creates a distinct visual appeal on watch cases and other components. It gives the metal a textured, matte appearance that stands out from traditional polished or brushed finishes. The resulting surface diffuses light, reducing reflections and creating a subtle, understated elegance.

Enhanced Scratch Resistance: The textured surface created through sandblasting helps to minimize the appearance of scratches and minor imperfections. This is particularly advantageous for watches that are meant to withstand daily wear and tear, as the sandblasted finish can help maintain the overall appearance of the timepiece over time.

Versatile Design Element: Sandblasted technology offers versatility in design, allowing watchmakers to create contrasting finishes by combining sandblasted areas with polished or brushed surfaces. This interplay of textures adds depth and visual interest to the watch, making it a captivating and unique piece.

Timeless Appeal: The sandblasted finish has a timeless quality that appeals to both contemporary and classic watch designs. It exudes a sense of sophistication and refinement while adding a touch of modernity to the overall aesthetic.

Numerous watch brands have embraced sandblasted technology, incorporating it into their collections. From sporty timepieces to elegant dress watches, the sandblasted finish offers a versatile option for watch enthusiasts who seek a distinctive and refined look. Many luxury watch brands utilize sandblasting as part of their manufacturing process to create unique limited-edition pieces or special editions.
