Horage
Horage is a Swiss watch brand based in Biel/Bienne. Internally developed mechanical movements are central to its history. However, the first Omnium, shown in 2009, used an externally sourced movement. The history should therefore not imply proprietary movement production from its first watch.
K1 Automatic debuted in 2015 and underpins later projects. It is a modular automatic movement with options including a power-reserve display and large date. The K2 micro-rotor and K-TOU tourbillon are separate movement families, not alternative names for K1.
Identify the reference, calibre and production variant before describing a used watch's functions and specifications. Compare the movement with original documentation and service records. A newer version sharing a model name is insufficient evidence for an older example.
