Bell & Ross has spent years building a reputation around one distinctive idea: watches that look like they came straight out of a cockpit. Its Lum series takes that further, using Super-LumiNova not just for function but as a design language in itself. Now that approach has reached the brand’s dual-time watch with the BR-03 GMT Green Lum.
As an authorized Bell & Ross dealer, Precision Watches follows the brand’s releases closely. Here is a closer look at what makes this new limited edition stand out.
The Northern Lights Dial
The dial is where this edition earns its name. It runs a vertical gradient from green at the top to black at the bottom, evoking a night sky lit by the aurora.
The green theme carries across the whole face. The numerals, hour markers, and hands are all coated in pale green Super-LumiNova C3, which glows green in the dark. Meanwhile, the hands themselves are blackened rather than polished steel, which gives this version a more overtly military character than the standard Bell & Ross BR03 GMT. Two smaller details complete the aviation theme. The seconds hand carries an aeroplane-shaped tip, while the GMT hand is an openworked triangle. As a result, the dial reads as a genuine flight instrument rather than a decorative interpretation of one.
The Case and Bezel
The Green Lum uses the square case that has defined Bell & Ross since the beginning. It measures 42mm across and 11.3mm thick, with the familiar circle-within-a-square layout and a screw at each corner.
Key specifications:
- 42mm x 42mm stainless steel case
- 11.3mm thick
- Bidirectional 24-hour rotating bezel with a polished black ceramic insert
- Flat sapphire crystal with anti-reflective coating
- 100 meters water resistance
The bezel is a notable update on this edition. Its markings are treated with the same green-emitting Super-LumiNova C3 as the dial, so the whole watch lights up rather than just the hands. Because of this, the Green Lum delivers on the Lum series promise more completely than a conventional lumed watch. The case finishing also reflects the brand’s recent refinements, with brushed surfaces and wide polished bevels along the edges.
The Movement and GMT Function
Inside sits the Bell & Ross calibre BR-CAL.303, an automatic movement based on the Sellita SW330-2. It runs at 28,800 vibrations per hour and offers a 54-hour power reserve, using the caliber’s most recent version with the extended reserve.
One point is worth understanding for anyone considering a GMT. This is what enthusiasts call an office-style GMT, meaning the crown adjusts the central 24-hour hand independently rather than the local hour hand. In practice, that makes it well suited to tracking a second time zone from home, though a traveller’s GMT handles time zone changes more conveniently on the road.

Straps and Availability
The BR-03 GMT Green Lum comes on a black rubber strap, with a second strap in ultra-resilient black synthetic fabric included in the box. Both fasten with a steel pin buckle.
The watch carries the reference BR0393-GN-ST/SRB and is a limited edition of 500 pieces. As a result, it sits alongside the brand’s other Lum releases as a collector-focused piece rather than a permanent-collection model.
The Latest from Bell & Ross
The BR-03 GMT Green Lum is a good example of what Bell & Ross does well. It takes an established model, the BR-03 GMT introduced in 2021, and reworks it around a single strong idea. Because of this, it feels like a genuine variation rather than a color swap.
