Introduction
The Bell & Ross BR-X3 is not a watch that whispers. With its aggressively skeletonized dial, titanium case, and aviation-grade engineering, it announces itself with the same unapologetic presence as a private jet touching down on a remote airstrip. This is a timepiece built for the kind of collector who values mechanical transparency as much as they value a clean departure from convention.
In the world of luxury horology, Bell & Ross has carved a distinct niche by fusing military instrument aesthetics with haute horlogerie finishing. The BR-X3 continues that legacy, but with a modern twist: it’s lighter, more technical, and more wearable than its predecessors. Whether you’re tracking elapsed time at a track day or simply making a statement at a gallery opening, the BR-X3 delivers on both form and function.
This review dives deep into the BR-X3’s movement, materials, and market position — because in 2025, a watch isn’t just a tool; it’s a cultural signal. And the BR-X3 signals that you know exactly what you’re doing.
Manufacture History
Bell & Ross was founded in 1992 by Bruno Belamich and Carlos Rosillo, two friends who shared a passion for aviation and design. The brand’s early watches were heavily inspired by cockpit instruments, particularly the square shape of aircraft gauges. The iconic BR 01, launched in 2005, cemented the square case as the brand’s signature. Over the years, Bell & Ross has expanded into dive watches, chronographs, and skeletonized models, always maintaining a connection to professional and military tools. The BR-X3 is the latest in the X-series, which began with the BR-X1 in 2014, pushing the boundaries of skeletonization and material innovation.
Movement
At the heart of the BR-X3 beats the BR-CAL.323, an automatic movement based on the reliable Sellita SW300-1. While not fully in-house, Bell & Ross has heavily modified the caliber with extensive skeletonization, circular graining, and blued screws. The openworked rotor allows a clear view of the mainspring barrel and escapement, reinforcing the watch’s transparent theme. The movement is COSC-certified, ensuring accuracy within -4/+6 seconds per day. With a 70-hour power reserve and a frequency of 28,800 vph, it offers modern performance. The date complication is displayed at 4:30, a subtle nod to the brand’s instrument heritage.

Wrist Feel
On the wrist, the BR-X3 is surprisingly light. The grade 2 titanium case shaves off significant weight compared to the steel BR 03 models, making it comfortable for all-day wear. The 41mm square case wears closer to a 44mm round watch due to the geometry, but the short lugs and integrated rubber strap keep it from feeling oversized. The skeletonized dial creates an airy feel, and the rubber strap is supple with a subtle texture that grips without being sticky.
The balance is excellent — the watch sits flat on the wrist without tipping. The crown is signed and easy to grip, though the push-pull action is firm. The sapphire crystal is slightly domed, adding a touch of vintage character to an otherwise futuristic design. Overall, the BR-X3 feels like a piece of tactical equipment that somehow doubles as jewelry.
Accuracy
In real-world testing, the BR-CAL.323 consistently runs within -3 to +5 seconds per day, well within COSC standards. The 70-hour power reserve means you can set it down on Friday and pick it up Monday without resetting. The hacking seconds hand makes precise time-setting straightforward, and the date change is crisp at midnight.
Occasions
The BR-X3 is best suited for sport, daily wear, and casual settings. Its rubber strap and skeleton dial make it less appropriate for black-tie events, but it shines at the gym, on a weekend getaway, or at a casual dinner. The 100m water resistance means you can swim with it, though the open dial might not be ideal for deep diving.
Wrist Presence
4/5 — The skeletonized dial and titanium case draw immediate attention without being gaudy. It’s a conversation starter, but the matte finish keeps it from screaming for attention. Perfect for the collector who wants to be noticed by those in the know.
Reference Variants
The BR-X3 is available in several configurations. The blue skeleton (BRX3R-BL-TI/SRB) is the standard model, with blue accents on the bridges and hands. A black skeleton variant (BRX3R-BK-TI/SRB) uses a DLC-coated titanium case and black PVD hands for a stealthier look. A limited edition carbon skeleton (BRX3R-CE-TI/SRB) features a forged carbon bezel and dial inserts, adding texture and exclusivity.
Family References
The BR-X3 sits within the X-series, which includes the BR-X1 (2014) and BR-X2 (2018). The BR-X1 was the first skeletonized chronograph from Bell & Ross, while the BR-X2 introduced a more refined, thinner case. The BR-X3 refines the formula with a focus on lightweight materials and a cleaner dial layout.
Other Notable Models by Bell & Ross
Beyond the X-series, Bell & Ross offers the BR 03-92 (a classic square diver), the BR 05 (an integrated bracelet sports watch), and the BR 01-92 (the original aviation-inspired model). Each carries the brand’s DNA but targets different segments of the market.
Similar Watches
If you’re drawn to the BR-X3, consider the Hublot Big Bang Unico Titanium for a similar skeletonized, lightweight vibe. The Richard Mille RM 011 is the ultimate expression of the genre, but at a much higher price. For a more accessible option, the TAG Heuer Carrera Skeleton offers a round case and a lower entry point.
Homages
For those on a budget, the Pagani Design PD-1661 offers a skeleton dial in a steel case with a Seiko movement for around $120. It lacks the titanium and COSC certification, but captures the openworked aesthetic.
Investment Value
The BR-X3 has an MSRP of $8,500 and currently retails at that price. On the pre-owned market, examples range from $6,000 to $7,500, depending on condition and completeness. The trend is stable — not a hot investment, but not a depreciating asset either. Hold recommendation: buy for the design, not for flipping. No major auction history.
Service Interval
Bell & Ross recommends a service every 5 years. The approximate cost is $600, and while authorized service is preferred, any competent watchmaker familiar with Sellita movements can perform the work. The movement is robust and parts are readily available.

Buy it for the design, wear it with purpose, and don’t expect it to fund your retirement.
