A bold expression of independent watchmaking at its most playful: the Behrens x Konstantin Chaykin Ace of Hearts reimagines Chaykin's iconic Wristmons "face" concept through Behrens' avant-garde engineering. This 2025 full set is presented in like-new condition with virtually no signs of wear. The distinctive square diamond carbon case houses the proprietary in-house Behrens BM07 manual-winding calibre, developed specifically for this collaboration. The left "eye" reads the hour, the right "eye" the minutes, the lower rotating disc tracks running seconds, and the upper aperture shows the remaining power reserve, completing the mechanical "face." It arrives complete with its original strap plus an additional red OEM Behrens strap, allowing the watch to take on an even bolder personality. Serial No. 082.

The story

The Story

Some watches tell the time. The Behrens x Konstantin Chaykin Ace of Hearts tells you who is wearing it. This is a collaboration between independent watchmaker Konstantin Chaykin, whose Wristmons "face" watches became a cult phenomenon in the independent watch world, and Behrens, an innovative Chinese manufacturer known for avant-garde engineering and in-house movement architecture. Together they reinterpret the Wristmons concept through an entirely fresh, mechanical lens. The result is a piece that wears its character openly: irreverent, technical, and unlike anything else in a collector's box.

The Face: Mechanical Theatre

The display is the whole point. The left "eye" indicates the hour, the right "eye" displays the minutes, while the lower rotating disc serves as the running seconds. Above them, an aperture shows the remaining power reserve, completing the playful yet deeply mechanical "face" design. It is a watch that rewards a second look and starts conversations the moment it leaves the cuff.

The Craft: Titanium & the BM07 Calibre

The distinctive square case is crafted from titanium, keeping the watch light and comfortable despite its bold presence. Inside beats the proprietary Behrens BM07 manual-winding movement, developed specifically for this collaboration. With 247 components, 35 jewels, a 4Hz (28,800 vph) beat rate, and approximately 46 hours of power reserve, the BM07 demonstrates the genuine technical capability of modern independent watchmaking. This is not a novelty with an off-the-shelf movement: it is a purpose-built calibre engineered to drive an unconventional display.

Condition & What's Included

This example is a 2025 full set in like-new condition, showing virtually no signs of wear. It arrives complete with its original Behrens presentation box, the 2025-dated warranty card, manuals and documentation, the original OEM strap, and an additional red OEM Behrens strap that lets the watch take on an even bolder personality. This is Serial No. 082. Unlike traditional luxury watches, the Ace of Hearts is designed to spark conversation and to signal its owner's appreciation for independent watchmaking and unconventional engineering. A rare and highly collectible piece that blends Konstantin Chaykin's imagination with Behrens' modern mechanical ingenuity.
