Carillon Repetition Minute, Redesigned — Discussions on the sidelines of Geneva Watch Days 2026

SWANDEX, Switzerland - Technology Network, the developer of Carillon Repetition Minute, is introducing the redesigned version of its minute-repeater companion app this week, en marge des Geneva Watch Days 2026 (September 2–6), the independent watchmaking event held annually in Geneva. SWANDEX did not exhibit the way many of the participating watch brands do — the connection was simpler and more direct: walking the open days during the week and talking with a handful of people who already work in the industry the app takes its inspiration from.

Carillon Repetition Minute brings the acoustic language of a fine watch complication to the phone in your pocket. Every quarter hour, a short chime marks the time; on the hour, the hour is struck, grouped in fives so that even eleven strikes are heard as a shape rather than counted one by one. A press of the dial calls the full repetition on demand — hour, then quarters, then minutes past the quarter — the same sequence a répétition minute pocket watch or wristwatch has used for centuries to tell time by ear alone, in the dark, in a meeting, or whenever a glance at a screen is not an option.

Those conversations mark a new phase for the app more than the event itself does: after two years of continuous, incremental engineering across every operating system it runs on, SWANDEX is positioning Carillon Repetition Minute as a mature, dependable piece of software rather than a first release, and is starting to reach out to horology and lifestyle media directly, in addition to the channels it has already built with watch collectors and enthusiasts.

Built and rebuilt to survive real phones, real years

Since its original launch, Carillon Repetition Minute has been re-engineered at the operating-system level, through several major iOS and Android platform updates, to keep its chimes reliable in the conditions modern mobile operating systems are increasingly built to prevent: background processes being silenced, throttled, or killed outright to save battery. That work now underpins the app's current architecture.

“A minute repeater took the finest watchmakers in the world centuries to perfect, purely so time could be told without looking. We are not trying to replace that watch. We built the software so that idea — hearing the time rather than checking it — could live quietly in a phone everyone already carries, and survive every update Apple and Google throw at it in the process.” SWANDEX, Switzerland - Technology Network

A quiet way in, a wider audience next

Geneva Watch Days brings independent and established watch brands together with press, retailers, and collectors each year in Geneva, in parallel with the city's broader watchmaking calendar — many of them renting stands, stage time, or hosted suites in hotels along the lake to do it. SWANDEX did none of that. What the open days offered instead was the chance to talk, informally, with a handful of people who already work in watchmaking, and to hear firsthand how an app built around the sound of a répétition minute complication reads to people who spend their careers around the real thing. Those conversations are what SWANDEX is building on now, reaching out directly to horology publications, watch-industry press, and broader lifestyle media to introduce the redesigned app to a wider readership.
