AK-04
Tourbillon Régulateur
A Tribute to Horological Tradition and Symmetry
Celebrating Design and Innovation

Tourbillon Régulateur
The AK-04 represents ATELIER AKRIVIA’s dedication to precision timekeeping - with a twist. The AK-04 masters traditional watchmaking techniques and complications, but presents them in a modern case with a regulator-style display. Inspired by historical “school” watches produced by watchmaking apprentices to demonstrate their talent, the AK-04 is a testament to precision, balance and artistry.

A Study in Symmetry and Craftsmanship
The 42.5 mm case of the AK-04 exemplifies minimalism but with character. The broad, chamfered lugs mirror the intricate bevelling on the movement. The dial’s regulator layout positions the hours at 12 o’clock, with the minutes in the centre, and a one-minute tourbillon at six o’clock that doubles as the seconds indicator. In typical ATELIER AKRIVIA style, the symmetrical, linear dial emphasizes balance and clarity.

Precision at Its Core
Within the distinctive case is the AK-04 caliber, a masterpiece of engineering and decoration. Completing one rotation every 60 seconds, the large 13.7 mm tourbillon carriage contains a Breguet balance spring and ATELIER AKRIVIA’s proprietary balance wheel operating at 21,600 beats per hour. Powered by a single barrel, the movement offers an impressive 100 hours of autonomy. Featuring 50 inward angles along the bevelling and a variety of hand-finished details, the movement showcases traditional craftsmanship at its finest.

A Testament to Legacy and Ambition
Launched on the occasion of ATELIER AKRIVIA’s third anniversary, the AK-04 represents years of dedication to refining traditional watchmaking techniques while forming a distinct design identity. The meticulous finishing, including domed anglage, hand-applied Côtes de Genève, and circular graining, highlight the brand’s commitment to pushing the boundaries of haute horlogerie. Made in stainless steel, titanium, and 5N rose gold, the AK-04 is both a tribute to tradition and a beacon for the future of horology.
