Don’t be fooled by the diamonds. Bell & Ross is still an aeronautics-inspired tool watch brand above all else.

As with most other aeronautical companies, space is the final frontier. In 2025, the French watchmaker introduced the out-of-this-world BR-03 Astro, and now it returns its gaze to the heavens with the starry-dialed BR-05 36mm Blue Diamond Eagle.

The diamond-studded dial emphasizes the versatility of the BR-05 design. The steel integrated sports watch was introduced in 2019, and the 36mm size used here came along in 2025.

It is a sleeker, sportier take on the brand’s signature rounded-off square case with four exposed screws, inspired by cockpit instrument panels. It provides such a clean background that you can do just about anything with the dial, and even a complete departure like this feels natural.

The tiered stainless steel case blends vertical satin brushed surfaces with polished chamfered edges to articulate the industrial geometry. It features a large crown guard, and the angled lugs connect to a tapered, integrated steel bracelet with brushed H-links and polished center links.

It is perfectly sized for all-purpose daily wear, which is the aim of most BR-05 36mm references, but this astronomical dial shifts the design into formal territory. As do the diamonds, which are the first to appear in this collection.

Look to the stars

The industrial design gives the impression of gazing out of the porthole on a spaceship floating through the galaxy.

Just like the BR-03 Astro, the foundation of the dial is an aventurine glass plate atop a rigid brass base. The only other markings on the dial, aside from an applied metallic Bell & Ross logo at 3:00, are eighteen diamonds.

Three different sizes of diamonds are used, held in place by custom brass settings obscured by the dial plate. Twelve of them comprise the hour markers, and seven of them form the constellation Aquila, with the 2:00 hour marker pulling double duty.

More specifically, the dial displays Aquila as it is seen between 10:00 and 11:00 in the Northern Hemisphere. The anchor of the constellation is the star Altair, which is represented by the largest diamond on the dial, situated at approximately 10:30.

Aquila means “eagle” in Latin, hence the watch’s name, and the constellation represented the bird that carried Zeus’s thunderbolts in Greek mythology.

Time is indicated by a set of chamfered, polished metallic stick hands, and the dial is capped by a flat sapphire crystal with an anti-reflective coating.

To help decipher the dial, a star map of the Aquila constellation is etched into the caseback. It covers a BR-CAL.329 movement, which is a customized Sellita Caliber SW-300 automatic that beats at 4Hz and provides a 54-hour power reserve.

Availability and pricing

The Bell & Ross BR-05 36mm Blue Diamond Eagle is available now from Bell & Ross for $5,000. It surpasses the fully-mirror-polished reference released in 2025 as the dressiest, most dazzling entry in the integrated sports watch collection.
