Since 1952, the Breitling Navitimer B01 Chronograph (41mm, 43mm & 46mm) has served as the wrist-worn flight computer of commercial and military aviators, accompanied by the bullet-bracelet Chronomat B01 42 and the rugged Avenger & Superocean Heritage series. Today, BLS Factory (BLSF), GF Factory, and TF Factory produce Breitling super clones with functional circular slide-rule bezels, blue-AR cambered sapphire crystals, and openworked B01-decorated chronograph movements.
- Zero-Gap Circular Slide Rule Alignment (BLSF Navitimer B01): On the 43mm Navitimer B01, rotating the beaded bezel turns the inner logarithmic ring under the domed sapphire crystal so the red ’10’ and ’60’ multiplication/division indices align cleanly with the dial scale.
- 3D Applied AOPA Winged Logo: The 2022–2026 generation Navitimer B01 restores the historic Aircraft Owners and Pilots Association (AOPA) winged shield at 12 o’clock with crisp, diamond-cut gold or rhodium facets.
- Iconic Rouleaux ‘Bullet’ Bracelet (GF Chronomat B01 42): Cylindrical brushed steel tubes linked with polished chamfers and an integrated butterfly clasp.
- Date Window Inside the 6 o’Clock Sub-Dial: Unlike older models with a 4:30 date window, the latest BLSF Navitimer B01 places a color-matched date aperture neatly inside the 6 o’clock 12-hour register.
1. Navitimer B01 43mm (BLSF): Reverse Panda, Ice Blue, Mint & Emerald Green
Examine our Breitling Navitimer B01 43mm BLSF Reverse Panda Black/White, Breitling Navitimer B01 43mm BLSF Blue Dial, and Breitling Navitimer B01 43mm BLSF Emerald Green Dial. Notice how the domed sapphire crystal is treated with Breitling’s signature double-sided anti-reflective coating, making the crystal practically disappear under cockpit or office lighting while protecting the finely printed logarithmic tachymeter and nautical-mile scales.

Collector FAQ & Pre-Shipment QC Answers
Can I actually perform fuel/speed calculations with the BLSF Navitimer slide rule bezel?
Yes! The outer bezel rotates smoothly in both directions, aligning the outer logarithmic scale against the fixed inner scale for real multiplication, division, and unit conversions.
What water precautions should I take with a Navitimer B01?
Just like a genuine Breitling Navitimer (which is rated to 3 bar / 30m because of the rotating slide-rule crystal assembly), the Navitimer is splash- and rain-resistant, whereas the Superocean and Avenger lines are built for swimming and diving.
