SJX and Habring² Conclude Trilogy with Chrono Felix Perpetual 'Star'
The final watch in a three-part collaboration, the Chrono Felix Perpetual 'Star', is a limited edition of 30 pieces priced at $28,500, combining a monopusher chronograph with a perpetual calendar.

The Habring² x SJX Chrono Felix Perpetual 'Star' concludes a planned three-part collaboration between the Singapore-based magazine and the German independent watchmaker. Limited to just 30 individually numbered pieces, the watch is priced at $28,500 before taxes.
This is the third and final collaborative watch from SJX and Habring². It follows earlier models named MdS1 and MdS4, as well as a unique piece made for charity. The 'Star' marks the definitive end of the planned trilogy.
Limited Production and Specifications
The watch is strictly limited to 30 individually numbered units. It is powered by a hand-wound Habring² A11CP movement. This combines an A11 chronograph base with a Dubois-Depraz perpetual calendar module.
The movement operates at a frequency of 4Hz, or 28,800 beats per hour. It delivers 48 hours of power reserve when fully wound. The movement finishing was completed in Germany by Pöhlmann-Bresan. The chronograph is controlled by a single pusher.

Design and Material Details
The stainless steel case features brushed and polished surfaces. A triple-stepped bezel masks the calendar module and houses recessed adjustment pushers. The design retains wearable proportions.
The dial presents a gold-on-black vintage aesthetic. It has a glossy black lacquered base with matte sub-dials featuring a concentric finish. Eight applied gold-plated star indices serve as hour markers, a design inspired by vintage Rolex 'Galaxy' dials.
Gold-plated leaf-shaped hands indicate hours and minutes. A delicate, curved-tip seconds hand is for the chronograph. A gold-plated moon phase disc at 12 o'clock features a textured moon and stars with a friendly face. Various calendar indications are printed in gold.
The watch is worn on a patinated brown calfskin strap. It is secured with a stainless steel pin buckle that also features the 'Star' motif. The individually numbered case back repeats this star decoration.
Availability and Ordering
The Chrono Felix Perpetual 'Star' is exclusively available from SJX. A 40% down payment is required to secure an order. Deliveries are scheduled for January, February, and April 2027, fulfilled in the sequence orders are placed.
The piece will also be available in limited numbers at Shellman in Tokyo, priced at approximately 5 million yen before taxes. One observer commented on the increased price, saying, "Whew! Module or not, the 'evolution' of the monopusher has also brought a palatial palace buying increased price tag with it."
The 'Star' marks the final chapter of the planned trilogy between SJX and Habring².
