Product Specifications
The Ace of Hearts is the limited-edition co-branded masterpiece of BEHRENS and Konstantin Chaykin. Celebrating three years of partnership, this hand-wound watch combines BEHRENS' signature asymmetry with Chaykin's signature playful Joker spirit, infusing fine watchmaking with the art of Chinese Han Dynasty ceramic sculpture. This limited-edition luxury mechanical marvel is as rich in emotion as it is in mechanical excellence.
Movement: Caliber BM07 manufactured in-house
At the heart of this luxury mechanical watch is the hand-wound BM07 manufacture caliber with a 46-hour power reserve. Each component is meticulously crafted by hand:
-
Brushed plates
-
Mirror polished pivots
-
Carefully angled chamfers
The transparent case back reveals these mechanical touches of art, creating a captivating visual dialogue between the creator and the wearer.
Time display
The Ace of Hearts displays the time with a smile. Two “eyes” on the dial indicate the hours and minutes, while a red heart-shaped seconds hand, powered by BEHRENS’ patented stone-grinding mechanism, rotates in a whimsical pattern, like a grindstone. A discreet power reserve indicator at 12 o’clock informs you of the movement’s total autonomy of 46 hours.
Dial design: fusion of East and West
The dial pays homage to Han-era Chinese craftsmanship, reflecting the character of the Pottery Storyteller Beating a Drum, while also taking up Konstantin Chaykin's iconic Joker character and Behrens' signature asymmetry. This timepiece, protected by 11 patents, is a bridge between:

Cultural traditions

Playful tales
