Konstantin Chaikin and BEHRENS Release the Final Chapter of Ace of Heart Collection

A Grand Finale for Watch Enthusiasts: Ace of Heart Collection



In the world of luxury watchmaking, every collaboration tells a story, and the highly anticipated release of the final chapter of the Ace of Heart collection by Konstantin Chaikin and BEHRENS is nothing short of remarkable. This collaboration merges the distinct design elements of BEHRENS's asymmetrical Ultra Light model with Chaikin's iconic Joker motif, creating a striking display that will appeal to collectors and aficionados alike.

The Ace of Heart collection follows the launch of previous limited editions in 2025, consisting of a Grade 5 titanium model with only 600 pieces made, alongside 150 units of the SPS Black Carbon model and another 150 units of the SPS White Carbon model. In a bid to captivate the hearts of watch lovers further, February 2026 will see the release of an 80-piece limited model made from blue sapphire crystal, adding an exquisite touch to this exclusive series.

Konstantin Chaikin: A Legacy of Innovation


Konstantin Chaikin, an independent watchmaker known for his innovative creations, garnered worldwide attention after revealing his Joker watch at the Basel Fair in 2017. This event represented a pivotal moment in his career, cementing his reputation in the horology community. The initial release of the Joker model drew acclaim from industry insiders, leading to the creation of the Crown model shortly thereafter. Chaikin's Crown watch later earned recognition at the Geneva Watch Grand Prix (GPHG), winning the Daring category in 2018, showcasing his unique ability to design timepieces that impart humor and joy.

Design Features of Ace of Heart


The Ace of Heart model carries a playful elegance, with the joker's mouth shaped to resemble a ceramic figurine from the Han Dynasty. The seconds hand transforms from a spade shape to a heart shape, adding a whimsical touch to its personality. At the heart of this timepiece lies the proprietary BM07 caliber, developed specifically for this collection. This movement boasts 11 leading-edge patented technologies, showcasing the manufacturers' commitment to horological excellence.

The seconds hand follows a unique trajectory along the heart-shaped perimeter, while the eyes of the joker indicate hours and minutes. Power reserve indications are elegantly displayed on the forehead, adding to the rich characteristics of this watch. Not only does BEHRENS prioritize inventive movements, but they also place great emphasis on materials. The Ace of Heart employs three distinct materials, ensuring that every detail is meticulously crafted.
