At 43mm on a stainless steel bracelet, this Breitling Navitimer B01 mint green replica pairs the full-size chronograph platform with a pale sunburst dial and three black counters. Reference AB0138241L1A1 sits in the upper tier of the Navitimer range by combining Breitling’s in-house B01 caliber (a clone Cal. B01 in this watch), the signature slide rule bezel, and a dial color that has gained significant traction across Swiss watch brands in recent seasons. The mint is pale but not timid: it reads clearly on the wrist and shifts tone depending on the angle of light.

Whatever the dial colour, the pushers should feel crisp, with a clear click at start and at stop, and our guide’s QC list covers the shape and action of the crown and pushers.

Green dials on steel cases tend to look more casual than blue or black equivalents. That tonal warmth makes the AB0138241L1A1 a natural pairing with earth-toned clothing, though it works just as well against a white shirt and dark trousers.

Clone Cal. B01 Behind the Mint Green Dial

The clone Cal. B01 inside this reference copies the column-wheel and vertical-clutch layout of the genuine B01, providing smooth chronograph starts and about 55 hours of power reserve (the genuine B01 gives 70). Where the green dial is the visual story, the movement is the mechanical backbone that distinguishes B01 Navitimers from earlier models that relied on third-party chronograph calibers. The AB0138241C1A1 blue dial version shares identical case and movement specifications, so the choice between the two comes down entirely to dial preference.

Mint Green Navitimer B01 With Black Counters

Breitling introduced green-dial Navitimers to capitalize on a broader industry trend, but the execution here is specific to the brand: the slide rule scale around the bezel adds visual density that most green-dial competitors lack. That complexity is what makes the Navitimer either magnetic or overwhelming depending on personal taste. For those in the first camp, the AB0138241L1A1 brings a fresh pastel to the full-size B01 chronograph. On this super clone the black counters stop it from looking like a fashion piece: they tie the dial back to the black slide-rule scale and the instrument look of the original.
