Ataelier Haute Complication: Dual Time (steel), 99 Pieces

Last Updated: January 28, 2026By

When you slip on the Ataelier Haute Complication Dual Time in stainless steel, you’re not just wearing a timepiece — you’re wearing a story. A story of an architect-turned-watchmaker, of unexpected visual flair, and of a limited run of only 99 pieces that makes it feel special before you even glance at the dials.

Overview

The Ataelier Haute Complication Dual Time in stainless steel is a compelling debut from independent maker Vladimir Négault, combining imaginative design with practical dual-time functionality. Limited to just 99 pieces, the watch brings a unique visual language to independent horology — one rooted in the founder’s architectural background and experience under François-Paul Journe. At 41 mm in diameter and just 9 mm thick, the polished 316L steel case offers a comfortable profile that slips easily under the cuff yet stands out on the wrist.

Its dial layout is unconventional and expressive, with an arched home time/day-night display dominating the upper half and a decentralised local time counter below, framed by bold numerals and blued skeletonised hands. Powered by the in-house Calibre Architecture Mécanique N°1, a hand-wound German silver movement running at 3 Hz with a 42–45 hour power reserve, the Dual Time delivers both technical substance and artisanal finishing visible through the sapphire caseback.

The resulting piece is expressive, practical for travellers, and deeply rooted in independent craftsmanship — a distinctive addition for collectors seeking originality and personality over mainstream logos.
