Bremont’s 2025 novelties at Dubai Watch Week distil the brand’s current direction with unusual clarity: high-complication watchmaking presented through a distinctly contemporary, often architectural design language, and framed inside robust “proper watch” cases rather than precious, untouchable showpieces. The Skeletonised Altitude Perpetual Calendar GMT Monopusher and the Terra Nova 40.5 Jumping Hour Aventurine sit on different ends of the complication spectrum, yet they share a focus on tactile functionality and clean, legible layouts that avoid gratuitous theatrics.
On the Skeletonised Altitude Perpetual Calendar GMT Monopusher, Bremont has taken what was already a densely equipped dial and removed the solid backdrop, replacing it with a blue skeleton structure that behaves more like a bridge system than a conventional dial. The openworked architecture exposes the Agenhor module and base calibre while retaining clear reading planes thanks to applied numerals and indexes filled with white Super‑LumiNova with blue emission, which sit on the remaining dial ring and skeletal crosspieces.
The display is carefully tiered: at 12 o’clock a domed globe disc, echoing the earlier Terra Nova Dual‑Time Tourbillon, serves as a 24‑hour GMT indication with day/night sectors, with a slender arrow indicating home time against the peripheral scale. At 9 o’clock, running seconds are presented on a sector‑style sub‑dial, the hand rendered as a lume‑tipped two‑blade propeller that anchors the watch in Bremont’s aviation‑centric Altitude design language.
The perpetual calendar indications are divided across the lower half of the dial, with a radial pointer‑date at 6 o’clock framed by circular graining and a black sub‑dial ring, and a particularly ingenious month/leap‑year display at 3 o’clock. Here a four‑blade propeller hand, with three white tips and one red, moves in 172 micro‑increments across a four‑year cycle, the first quadrant also carrying the 12 months; the red tip indicates the position in the leap‑year cycle, while the blade crossing the first quadrant shows the current month. The movement of this indication is so gradual that its advance is imperceptible to the naked eye, yet the display is instantly intuitive once understood.
The Terra Nova 40.5 Jumping Hour Aventurine takes the opposite route, opting for minimalist apertures on a rich, almost nocturnal dial rather than a multitude of hands. The blue aventurine surface, cut with diamond tools and then painstakingly polished before being mounted on a metal backing plate, offers depth and sparkle that shifts with the light, but Bremont wisely resists overcrowding it with print.
Hours and minutes are displayed in adjacent windows at 9 o’clock, bordered by applied frames that visually balance the negative space of the dial. The hour numerals are filled with white Super‑LumiNova with green emission, while the minute numerals are crisply printed in white, leaving the rest of the aventurine largely untouched. A central running seconds hand in full white Super‑LumiNova with green emission sweeps the dial, supported by a silver printed minute track and hour markers, with simple lume plots at the cardinal positions to preserve field‑watch legibility.
Behind the Skeletonised Altitude sits a layered construction that pairs a custom Agenhor perpetual calendar GMT monopusher module with Bremont’s BHC9192 calibre, itself built on the Sellita AMT6900 manual‑wind base. The combined height of module and base movement is just 6.8 mm, which allows Bremont to keep the case thickness to 12.65 mm despite the number of functions.
The BHC9192 is a mechanical hand‑wound movement with 19 jewels, a Glucydur balance and a power reserve of 50 hours, regulated to an accuracy of minus six to plus six seconds per day, placing it in chronometer‑adjacent territory on paper. Winding is tactile and purposeful, a deliberate choice in a watch where the relationship between wearer and mechanics is part of the appeal, especially when so much of the module is visible dial‑side.
Agenhor’s module is the aesthetic and technical focal point. The bridges are finished with Côtes de Genève, their straight graining and anglage clearly visible through the skeleton dial, and the architecture has a clean, engineered order that suits Bremont’s tool‑watch DNA. The monopusher lever carries a finely engraved Wayfinder logo, a subtle nod to the collaboration that adds character without veering into decorative excess. The mono‑pusher itself, integrated into the crown, controls the GMT globe by advancing the arrow hand in one‑hour jumps, while discreet correctors at two and four o’clock manage the date and month/leap‑year settings respectively.
The perpetual mechanism’s party trick is the ultra‑fine stepping of the month/leap‑year propeller, whose 172 micro‑jumps across four years correspond to an angular change of just under 2.1 degrees every eight days. This approach spreads mechanical effort evenly and avoids the violent “end of month” releases that can stress components, aligning with Agenhor’s reputation for elegant mechanical solutions.
In the Terra Nova Jumping Hour Aventurine, the star is the Bremont calibre BC634, developed with Sellita under an exclusive two‑year agreement and first presented earlier in 2025. This automatic movement runs at 28,800 vibrations per hour, uses a Glucydur balance, Anachron balance spring and Nivaflex mainspring, and delivers a healthy 56‑hour power reserve, striking a useful balance between modern specifications and servicing practicality.
Technically, the centrepiece is the high‑torque jumping hour mechanism, designed to deliver an instantaneous hour change in under one tenth of a second. In practice that means the hour disk snaps cleanly from one numeral to the next with a crisp, controlled jump rather than a lazy creep, a point that will appeal to enthusiasts who enjoy the discrete, almost digital aspect of the complication. The movement layout supports the dial’s left‑justified windows, allowing the eye to travel naturally from hour to minute while the central running seconds hand reinforces the watch’s status as a daily‑wear field piece rather than a concept watch.
The Skeletonised Altitude Perpetual Calendar GMT Monopusher uses Bremont’s signature Trip‑Tick construction rendered here in lightweight grade 2 titanium, with satin and polished surfaces offering contrast and depth. The three‑part architecture comprises a hardened, PVD black brushed titanium barrel sandwiched between front and back sections, giving the watch a technical, layered appearance and allowing Bremont to tune the profile and ergonomics independently of the bezel and lugs.
Dimensions are 42 mm in diameter, 49.62 mm lug‑to‑lug and 12.65 mm in thickness, with a 22 mm lug width that works well for the supplied quick‑release titanium bracelet or patinated leather strap. The absence of crown guards keeps the profile relatively clean while letting the monopusher crown stand proud enough for easy operation, an important point in a watch intended to have its GMT function engaged regularly. Water resistance is quoted at 10 ATM, or 100 metres, and the front crystal is a glass‑box sapphire with anti‑reflective treatment, which enhances the sense of depth over the skeletonised dial.
On the reverse, a titanium open caseback reveals the movement, with the decoration and Agenhor architecture visible despite the compact height. The interplay between the dark barrel, lighter titanium surfaces and the blue skeleton dial components underscores the Altitude’s identity as a technical cockpit instrument reinterpreted for contemporary, complication‑heavy watchmaking.
The Terra Nova 40.5 Jumping Hour Aventurine goes in a different direction, introducing Bremont’s first frosted 904L stainless‑steel case. The two‑piece case is delicately grained, producing a shimmering surface with countless microscopic facets that catch the light like a very fine, uniform frosting, enhancing the interplay between the crisp case lines and the glossy aventurine dial.
At 40.5 mm in diameter, 47 mm lug‑to‑lug and just 10.15 mm thick, the Terra Nova Aventurine has proportions that sit comfortably in the modern field‑watch sweet spot, aided by a 22 mm lug width and a quick‑release blue gradient leather strap that picks up the dial’s tones. The push‑in crown sits neatly at three o’clock, and the decorated stainless‑steel closed back reinforces the model’s tool‑watch positioning while leaving the aesthetic focus firmly on the dial and casework.
Water resistance matches the Altitude at 10 ATM/100 metres, and the front crystal is a flat anti‑reflective sapphire, which suits the dial’s planar, graphic composition and maintains a clear, distortion‑free view of the hour and minute apertures. The overall impression is of a refined but purposeful field watch that uses case finishing and dial material to lift the experience without compromising everyday robustness.
Taken together, these two Dubai Watch Week pieces sketch out Bremont’s current strategy with unusual precision: high‑function, high‑specification watches built around clear narratives of travel, exploration and contemporary British design rather than retro pastiche. The Skeletonised Altitude Perpetual Calendar GMT Monopusher – €44.400,00, positions the brand in a more rarefied arena, pairing an Agenhor perpetual GMT monopusher module with a carefully executed skeleton dial and a titanium Trip‑Tick case that remains practical, legible and water‑resistant enough to be used as intended.
The Terra Nova 40.5 Jumping Hour Aventurine – €10.750,00, limited to just 50 pieces worldwide, offers something more intimate and connoisseur‑oriented: a high‑torque jumping hour with an instantaneous change, wrapped in a compact frosted 904L steel field case and fronted by a luminous aventurine dial that does the talking without compromising legibility. Both watches underline Bremont’s push towards in‑depth technical partnerships, as seen with Agenhor and Sellita’s AMT/BC programmes, while retaining the brand’s established preoccupation with durability, water resistance and wearability.
