What to know
Horage’s DecaFlux PR takes a restrained approach to a useful complication: the power-reserve indication sits on the movement side, visible through the sapphire back rather than competing with the hands. The front remains a three-hand layout, distinguished by a blue lightning-shaped seconds hand. Polished black, sunray blue and polished white versions share a 40mm steel case measuring 9.98mm thick.
The COSC-certified K3 automatic uses a silicon hairspring and escapement. Horage reports magnetic-resistance testing to 30,000 gauss; this is a manufacturer claim, not a Chronolume test. Water resistance is 100 metres, and the three-link steel bracelet has 10mm of clasp adjustment. The official shop lists CHF 3,190 and anticipated deliveries from mid-December 2026, not an immediate-stock release.
