Top Time B01 Gino Bartali

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 13.3 mm it is a tall case, and it will catch on a cuff. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 70 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

AB01767A1C1X1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue matte dial with a stainless steel case. It was a limited edition. Introduced in 2025.

The B01 ND is Breitling's in-house chronograph without its date, the version of the B01 fitted to the Top Time. It powers 23 watches in this library, every one a Top Time. The [B01](/calibers/breitling-caliber-b01) is a column-wheel chronograph with a vertical clutch, a 70-hour reserve and a beat of 28,800 vph, certified by the COSC; leaving out the date removes the window at 4 o'clock and lets the Top Time keep the two-register "Zorro" dial of the 1964 original. The jewel count drops to 40. In the library it powers 23 [Top Time](/brands/breitling/top-time) references: the Classic Cars series for the Ford Mustang, Chevrolet Corvette and Shelby Cobra, the Fausto Coppi and the FC Bayern editions, at 41 mm and 38 mm. 10 are limited editions. The [B01](/calibers/breitling-caliber-b01) is the dated movement in the rest of the range, and the [B31](/calibers/breitling-caliber-b31) the three-hand movement of the Top Time B31.

22 other watches in the library run the Breitling Caliber B01 ND.
