Drawing on Breitling's celebrated racing chronograph heritage, the Top Time B31 presents a 38mm round stainless steel case fitted with a fixed bezel and a screwed-in sapphire caseback. The glareproofed scratch-resistant sapphire crystal shields a vibrant green dial equipped with index hour markers and luminescent hands, delivering clear readability across a range of conditions. Water resistance is rated to 100 meters / 330 feet.
Inside, the self-winding mechanical B31 caliber operates at 28,800 vph and offers a 78-hour power reserve — a movement visible through the transparent caseback. The analog display and considered proportions give this reference a character that sits comfortably between vintage inspiration and everyday wearability.
The watch is paired with a green calfskin strap secured by a tang-type clasp, and it arrives complete with its original box and papers. Reference AB3113171L1X1 is presented in unworn condition, dated to 2025.
