Industry News – Horage Launches New K2 Micro-Rotor Movement, With Unusual Production Plan


Horage is an original company within the Swiss watch industry. Based in Biel, the small brand ended up developing their own k1 automatic caliber, designed with the objective to be an efficient and reliable movement built on industrial production standards, but also deliver the flexibility in complications and decoration of a “manufacture” movement. At their sister engineering firm, THE Plus AG, a small team develops and manufactures movements managing all assembling operations (from T0 pre-assembly) in-house. Building on this experience, Horage now unveils their latest movement project, a micro-rotor built on their core component tool kit. And their plan to launch this new K2 movement is rather unusual.

For a long time, only a few watchmakers were producing movements. Most of the industry was sourcing from the same movement manufacturers; ETA/Sellita for industrial movements and a few high-end companies such as Frédéric Piguet, Lemania, Zenith or Girard-Perregaux, to name a few. To ensure a steady supply of movements, boost their image and create products adapted to their needs, brands started to develop their own mechanical movements. However, these so-called manufacture movements can rarely be produced at the same price as industrial movements. Among other reasons, scales are critical…

If it is not rare, in other industries, to see companies join forces and embark on common development and production projects, it is much less frequent in the watch industry. Horage is now initiating such a joint manufacturing project by inviting partner brands to access their latest micro-rotor movement K2. 

Horage is seeking eight brands as venture partners to secure the new movement at acceptable OEM pricing. The way brands would be involved and benefit from this common platform is flexible. The K2 movement opens the door to brands with a desire to explore movement making but with a lower financial risk. “Through hosted manufacturing each participating brand can secure their own intellectual property, develop their watchmaking infrastructure or simply have a source for their future movement production.”

The K2 movement has been conceived as a modern and modular micro-rotor movement, available in different configuration, to drive different complications.  30mm in diameter and with a thin base profile of just 2.9mm, the K2 runs at an unusual 3,5Hz frequency (or 25,200 vibrations/hour). If many modern calibers run at 28,800 vibrations/hour, this rather unusual frequency was seen as the optimal compromise by Horage, in particular to offer chronometer accuracy while providing a comfortable 65h+ power reserve. The movement is fitted with a silicon escapement for enhanced efficiency. Horage has developed its movement components to be materially interchangeable. Pre-production will be produced with steel hairsprings, however for final series production in 2023 silicon hairsprings will be put into use. 

Naturally, a multitude of standard decoration and functional options are available. Brand venture partners can further invest in and elaborate on decoration as well as complication. Skeletonization, perpetual calendar or chronograph are all feasible down the road. The K2 versions presented to brand partners are as follows:

  • 2.9mm – Hours, minute, small or centre second
  • 3.3mm – Hours, minute, small or centre second, and calendar
  • 3.6mm – hours, minute, small or centre second, 12-hour or 24-hour GMT, power reserve indicator and calendar

The roadmap for Horage is now to gather and select partner brands by the end of 2020 with a minimum commitment of just 300 movements per brand. The first movement samples would be delivered in 2021 with final serial production starting and delivering in 2023.
