SB04-E CHRYSOCOLLA PLATINUM

Painted by Nature

Gaze upon this image, and you begin to understand the very soul of the SB04-E’s Chrysocolla dial. Like a breathtaking aerial view of a secluded lagoon, the stone reveals a mesmerizing tapestry of turquoise and emerald hues, swirling with natural veining like currents in crystalline waters.

It’s a miniature landscape captured in stone, echoing the tranquility and boundless beauty of these hidden aquatic paradises.

Chrysocolla, in its organic formation, mirrors the earth’s own artistry, bringing a piece of these natural wonders directly to your wrist.

Please note: Chrysocholla is a natural stone, and its colors can vary widely, including shades of turquoise, green, dark green, light or dark blue, and even areas that appear nearly black. These variations are beyond our control and are part of the unique beauty and character of Chrysocholla

Clear Purpose

One of the defining features of the latest generation of Sartory-Billard watches, also present in the new SB04-E, is the sapphire disk onto which the hour markers are applied.

This sapphire disk features an inner ring made of metal, with a chamfered edge polished using a diamond tool, while the outer surfaces of the ring are circularly brushed.

The disk is adorned with even-numbered markers crafted from metal, with all visible surfaces polished with a diamond-cut finish.

The Super-LumiNova® BGW9 pad printed minute track and odd-numbered markers showcase the brand’s signature Y-shaped design, inspired by the Eiffel Tower—a nod to the founder’s Parisian roots.

At just 0.3 mm thick, the sapphire disk is treated with anti-reflective coating on both sides, allowing a perfect view on the minute dial beneath it.

Pointing The Way

The hands are slender and feature diamond-cut edges, designed to catch and reflect light vividly, creating areas of brightness and shadow that give the hands a sense of depth and volume.

Both the hour and minute hands are linear brushed and are filled with BGW9 Super-LumiNova®, while the seconds hand includes a small polished tip, also diamond-cut for a brilliant finish. These hands interact dynamically with light, enhancing their elegance while subtly drawing attention to the beauty of the dial.

Exposed Highlights

The SB04-E bezel features a concave design that reflects light and its surroundings, creating an optical effect that visually reduces the watch’s thickness.

This design also brings the sapphire crystal—and consequently the dial—closer to the wearer’s eye, enhancing its beauty. The watch case alternates between polished and brushed surfaces, with chamfered and polished edges adding a refined touch.

A signature Sartory-Billard design element is the subtle separation between the short lugs and the main circular case. Combined with the concave bezel, these design features create an optical illusion of slimness, making the watch, which measures just over 10 mm in thickness, appear significantly thinner than it actually is.

Lineage Evolution

One distinctive feature of the SB04 range was the fluted ring decoration on the movement’s rotor. This essential design element has now been relocated from the rotor to the case back, allowing for a reduction of nearly 1 mm in overall case thickness, resulting in a slimmer watch.

The fluted pattern, engraved with a diamond tool, is applied to the case back and is available in both open and closed case back variations. This design choice not only a signature that enhances the watch’s elegance but also improves its overall proportions.

Better Interaction

The watch features a screw-down crown, ensuring water resistance up to 100 meters. The crown incorporates three distinct textures: the outer teeth are circularly brushed, the inner teeth have a matte finish, and the side of the crown is also circularly brushed.

With a diameter of 7 mm, it offers excellent grip while remaining comfortable against the wrist. A unique detail is the outer face of the crown, which is filled with BGW9 Super-LumiNova®, allowing it to glow in the dark as a nighttime visual signature. This crown face also displays the logo, crafted in metal, adding a refined touch.

The Raw Material

The Chrysocolla featured in our watches is a genuine gemstone, sourced responsibly and presented in its natural form as a boulder.

Recognizable by its beautiful blue-green hues, the chrysocolla boulder is expertly cut into slabs and crafted into dials in Germany, just one hour from our workshop. Please note: Chrysocholla is a natural stone, and its colors can vary widely, including shades of turquoise, green, dark green, light or dark blue, and even areas that appear nearly black. These variations are beyond our control and are part of the unique beauty and character of Chrysocholla.
