Autark Tourbillon Gradient Grey

The Horage Autark Tourbillon Gradient Grey (Power Reserve) is a lightweight, high-performance tourbillon engineered in Grade 5 titanium. The case measures 39.5mm in diameter, under 9mm in thickness, with a 48.3mm lug-to-lug span and 22mm lug width, offering a refined yet contemporary wrist presence. It features crown guards with a push-pull crown, a multi-layer anti-reflection sapphire crystal, an exhibition sapphire case back, and 100m water resistance. The Gradient Grey dial incorporates an integrated power reserve display and a 60-minute track, complemented by Swiss Super-LumiNova® appliques emitting a green glow. Centre hour and minute hands are paired with a blued seconds indicator mounted on the flying tourbillon cage, delivering a dynamic visual focus at 6 o’clock.

At its core is the in-house K-TMR micro-rotor tourbillon movement, measuring 3.6mm x 30mm, offering a 72-hour power reserve. It features a silicon hairspring, silicon escapement components, screw balance regulation, and hand-finished bridges available in anthracite. The titanium flying tourbillon cage weighs just 0.29 grams, constructed from 43 components with a 3.9mm thickness, incorporating a silicon pallet fork, escape wheel, and hairspring. Winding efficiency is enhanced by a rhodium-plated tungsten micro-rotor. The integrated Grade 5 titanium bracelet tapers from 22mm to 16mm and includes a 10mm micro-adjustment clasp in precise 1mm increments, fitting wrists up to 217mm, with optional 6mm extra links available. This early-run, limited colour scheme example is presented in mint condition, complete with box, papers, and warranty dated December 2024, and is supplied with an additional one-year TLE warranty for added reassurance.
