Independent British watchmaker Fears has launched its most complicated timepiece to date: the Brunswick 39 Perpetual Calendar. Priced at $28,500 and entering the brand’s core collection as a regular production model, the watch integrates a Dubois Dépraz 55115 automatic movement inside a 39mm stainless steel case measuring 10.1mm in total thickness.
The Bottom Line
- Strategic Milestone: Released during the brand’s ten-year re-establishment anniversary by Nicholas Bowman-Scargill, marking Fears’ first perpetual calendar.
- Engineering Profile: Utilizes a Dubois Dépraz module atop a Sellita SW300 base, achieving a 9.4mm case profile with 50 meters of water resistance.
- Market Positioning: Priced at $28,500 with shipping scheduled to begin from late-October, 2026, joining the core collection without a set production limit.
Engineering the Brunswick 39 Perpetual Calendar
Producing a perpetual calendar remains an engineering challenge for any watchmaker, and particularly for brands producing fewer than 1,000 watches a year. To achieve a high complication without sacrificing the wearability of its core design, the brand partnered with Dubois Dépraz. Together, they developed the Caliber 55115—a module set atop a hand-finished Sellita SW300 base.
Here is the math on the physical footprint: the watch spans 39mm in diameter and stands just 10.1mm tall, a figure that includes a 0.7mm domed sapphire crystal, leaving the machined 316L stainless steel case at 9.4mm. By keeping the profile restrained, Fears maintains the proportions characteristic of the Brunswick family.
Dial Architecture and Movement Specifications
The display utilizes a Silver Mink dial—coated in pure silver with a light frosting—that houses a trio of sunken sub-dials alongside a distinct moonphase indicator positioned at six o’clock. The date sits at three o’clock opposite the day of the week at nine o’clock, while the month and leap-year indicator are integrated at the top of the dial. The layout is tracked via diamond-cut, polished brass indexes coated in warm 18ct black gold.

Turn the watch over, and the open exhibition caseback reveals dark rhodium anglage, frosted bridges, and a solid 18ct gold oscillating weight engraved with the Bristol flower and polished cypher emblem. The automatic mechanism delivers a 47-hour power reserve while managing the calendar displays—adjusting automatically for the length of month and leap years—without requiring manual intervention until the year 2100.
