Amida Introduces The Digitrend OSII Black With Fully Luminous Prism Display
Following the revival of its iconic Digitrend collection, Amida expands the range with the new Digitrend OSII Black (Open Sapphire II Black), a limited-edition model that combines the brand’s distinctive prism-based time display with a darker, more technical aesthetic. Building on the Open Sapphire concept, the latest release introduces a redesigned internal structure and, for the first time, a fully luminous display that enhances legibility after dark.
First launched in 1976, the Digitrend stood apart from conventional watches thanks to its innovative digital-style display viewed through an optical prism. While retaining the original concept, the modern interpretation incorporates contemporary materials and mechanics, with the OSII Black representing the latest evolution of this unconventional design.
Open Sapphire Construction
The Digitrend OSII Black retains the collection’s recognizable wedge-shaped profile, measuring 39.60 mm long, 39 mm wide, and 15.60 mm thick. Despite its unusual architecture, the compact dimensions ensure a comfortable fit on the wrist.

A defining feature of the watch is the large transparent sapphire hood that covers the upper section of the case. According to Amida, this component is machined from a single block of sapphire crystal and serves both as a protective element and a showcase for the watch’s internal mechanisms. The transparent construction allows light to enter the case while offering multiple viewing angles of the movement’s display system.
Unlike the previous Open Sapphire edition, the new OSII Black features a closed stainless steel caseback secured by four screws. Water resistance is rated at 50 meters.
Redesigned Internal Architecture
Beneath the sapphire crystal, Amida has introduced a newly developed black-coated steel framework that surrounds the display mechanism. The dark treatment creates a stronger contrast with the luminous elements while giving the watch a more technical appearance.

The brand has also simplified the upper section of the display by removing the Amida logo previously positioned on the top plate, allowing greater visual emphasis on the exposed mechanics and display components.
Fully Luminous Digital Display
One of the most significant updates is the introduction of a fully luminous display. The enhanced light transmission provided by the sapphire structure allows the display elements to absorb more light and remain clearly visible in low-light conditions.

The jumping-hour numerals and scrolling-minute indication are coated with BGW9 Super-LumiNova, creating a bright blue glow in darkness. Additional luminous details integrated into the internal framework further enhance visibility and contribute to the watch’s distinctive nighttime appearance.
Light Reflecting Display System
As with previous Digitrend models, the OSII Black relies on Amida’s proprietary Light Reflecting Display (LRD) technology. Hours and minutes are displayed on horizontally positioned discs inside the case and are viewed through an optical prism located at the front.

The system combines a jumping-hour display with a scrolling-minute indication, creating the digital-style presentation that has defined the Digitrend since the 1970s.
Powering the display is an in-house-developed module mounted on the Soprod Newton P024 automatic movement. Operating at a frequency of 28,800 vibrations per hour (4Hz), the movement provides a power reserve of approximately 38 hours.
Strap, Bracelet and Availability
The Amida Digitrend OSII Black comes fitted with a black Alcantara strap featuring an orange calfskin lining and quick-release spring bars for easy strap changes. Buyers can also opt for an integrated stainless steel bracelet.

Limited to 150 pieces worldwide, the Digitrend OSII Black is priced at CHF 5,150 on the Alcantara strap and CHF 5,500 on the steel bracelet, before taxes.
