Drawing on Breitling's heritage of iconic chronograph design, the Top Time B21 references the bold aesthetics of the 1960s while employing distinctly modern materials. The 44mm round case is crafted from ceramic, finished in blue, and fitted with a fixed bezel that keeps the overall profile clean and legible. A scratch-resistant sapphire crystal protects the blue dial, which features index hour markers and luminescent hands for reliable readability across varying light conditions.
Inside, a self-winding mechanical movement developed in partnership with La Joux-Perret operates at 28,800 vibrations per hour and is supported by 30 jewels. The chronograph complication offers a 1/4-second timer with a 60-minute counter, lending the watch genuine utility for timing tasks alongside its design appeal. Water resistance is rated to 100 meters / 330 feet, adding a layer of everyday practicality.
The watch is presented on a blue calfskin strap secured by a fold clasp, complementing the ceramic case for a cohesive look. Offered in unworn condition from 2025, it is accompanied by its original box and papers.
