At first glance, the Black Pearl reveals little more than a deep black surface. Quiet, understated and elegant. The rose gold-plated hands and hand-applied indices provide a warm contrast against the dark surface.

As the light shifts, so does the dial.

Subtle flashes of rose, soft green and silvery blue begin to emerge beneath the dark surface. They never dominate the dial or distract from it. Instead, they quietly appear and disappear as the watch moves with you, giving each glance a different character. No two dials ever behave quite the same, because no two pieces of natural mother-of-pearl are alike.

This effect begins with a natural mother-of-pearl dial. A black lacquer is applied to its back side, allowing light to continue passing through the shell's translucent layers before reflecting back to the eye. As it travels through the mother-of-pearl's natural aragonite structure, the dial reveals the subtle iridescence hidden beneath its dark surface.

The signature horizontal lines of the Essence collection are then machined into the mother-of-pearl itself, adding depth and structure while preserving the shell's natural character. It is a dial that rewards a closer look and continues to reveal something new over time.

Inside, the Black Pearl introduces the next generation of the Essence. It is the first model to feature the updated Swiss Made Sellita SW200-2 Power+ movement, extending the power reserve from 41 to 65 hours while improving winding efficiency and shock resistance. Like every Essence, each movement is individually COSC-certified for chronometer-grade precision.

The case also incorporates the latest evolution of the Essence platform. A screw-down crown delivers water resistance to 100 metres, while the re-engineered butterfly clasp features an integrated micro-adjustment system, allowing the bracelet to expand by 3 or 6 millimeters instantly, without opening the clasp or removing the watch from the wrist.

Like every Essence, comfort is engineered into the watch itself. The patented Case Suspension System allows the case to flex gently on the wrist, adapting to natural movement throughout the day. Together with the micro-adjustable clasps on both steel bracelet and all rubber, nylon and leather straps, it creates a wearing experience that is as refined as the watch itself.

The result is an Essence that feels familiar, yet more refined in every detail. A watch that appears understated at first, but reveals its character the longer you wear it.
