This Breitling Navitimer B01 light blue replica carries the full-size 43mm case that defines the modern Navitimer B01 chronograph line. The light blue sunburst dial sits behind the signature circular slide rule bezel, delivering the aviation-calculator function that has been part of the Navitimer identity since 1952. At 43mm on a stainless steel bracelet with folding clasp, the AB0138241C1A1 wears noticeably larger than the 41mm variants, which matters if you prefer a chronograph that fills the wrist without feeling like an oversized dress watch.

Behind the light blue dial runs a clone Cal. B01, and our guide’s B01 versus Asian clone movements section explains how the genuine calibre and its copies compare.

Black Counters on a Light Blue Ground

The blue dial on this reference shifts between a soft powder blue in shade and a brighter sky blue under direct light. Black registers at 3, 6, and 9 maintain strong contrast against the blue surface, keeping the sub-dials legible even on a busy Navitimer face.

Light Blue Navitimer B01 Against the 2018 Navitimer 1

Breitling positions the B01 movement as its in-house chronograph caliber, offering a column-wheel mechanism and 70 hours of power reserve; the clone Cal. B01 in this watch keeps the column-wheel layout and runs for about 55 hours. The vertical clutch design means the chronograph seconds hand starts without the stutter common in lateral-clutch movements. For those comparing within the range, the AB0121211B1A1 black dial variant shares the 43mm diameter and the B01 calibre but uses the earlier 2018 Navitimer 1 case, and swaps the blue for a high-contrast black layout. Both sit within the Navitimer collection, yet the blue version reads more casual, while the black leans toward instrument-panel clarity.

A Pale Blue Chronograph for Weekend Wear

The 43mm blue Navitimer occupies a specific lane: large enough to be immediately recognizable on the wrist, colorful enough to work with weekend wear, and technical enough to satisfy anyone who values a column-wheel chronograph. Breitling has offered blue-dial Navitimers before, but the 2022 B01 platform, with its slimmer case and modern bracelet finishing, is the most recent take on the idea. This light blue clone puts the full aviation-chronograph experience in reach without the wait list that sometimes follows limited Breitling references.
