Replica Navitimer Watches

Our breitling navitimer replica collection features 24 models of the world’s most recognized pilot’s chronograph. Since 1952, the Navitimer has defined aviation horology with its circular slide rule bezel — a fully functional flight computer capable of calculating fuel burn, airspeed, climb rates and unit conversions. This lineup spans the B01 Chronograph 43 and 46, Automatic 41, the orbital-rated Cosmonaute and limited heritage editions. Sizes run from 41mm time-only to 46mm chronograph, with steel, rose gold and two-tone configurations. Each reference features the distinctive beaded bezel grip and bi-compax or tri-compax dial layouts. Browse the full aviation line below, or return to the Replica Breitling collection.

Key References

  • Navitimer B01 Chronograph 43 (AB0138) — The modern standard-bearer. 43mm steel case with the B01 in-house caliber, 70-hour power reserve and COSC certification. Three-register chronograph with 30-minute and 12-hour counters. The slide rule bezel remains fully operational. Available in black, blue, copper, green and silver dials — the most popular replica breitling navitimer reference.
  • Navitimer Automatic 41 (A17326) — A time-and-date Navitimer without the chronograph complication. 41mm with B20 caliber (70-hour reserve), the slide rule bezel is retained purely as a design element. Slimmer case profile makes it a more versatile daily wear option while preserving the full Navitimer identity.
  • Navitimer B01 Chronograph 46 (AB0127) — The large-format Navitimer for wrists that demand presence. 46mm diameter with the same B01 engine and slide rule function. The additional 3mm diameter improves bezel legibility and dial proportions for the chronograph registers. A favorite among collectors who want maximum Navitimer impact.
  • Navitimer Cosmonaute (AB0210) — The 24-hour dial variant, originally designed for Scott Carpenter’s 1962 Mercury-Atlas 7 orbital flight. Unlike the standard 12-hour Navitimer, the Cosmonaute displays all 24 hours on the dial — AM and PM visible at a glance. Manual-wind B02 caliber with 70-hour power reserve. A historically significant breitling navitimer replica watch for space enthusiasts.

Movement and Build

Chronograph Navitimers run the B01 in-house caliber — column-wheel mechanism, vertical clutch, 28,800 vph, 70-hour power reserve and COSC chronometer certification. The Automatic 41 uses the B20 caliber with the same 70-hour reserve. The Cosmonaute employs the B02, a manual-wind variant of the B01 with 24-hour display. Cases are 316L steel with satin-brushed surfaces and polished lugs. The signature beaded bezel grip features approximately 94 knurled protrusions machined around the circumference, allowing precise rotation with fingertip pressure. Dials use applied Breitling wing logos at 12 o’clock and printed Arabic or baton indices depending on the reference. The slide rule comprises two concentric logarithmic scales — the outer rotating and the inner fixed — machined with 420+ graduation marks. Sapphire crystals with anti-reflective treatment cover the dial; exhibition casebacks reveal the decorated B01 or B02 movement.

How to Choose Your Navitimer

If chronograph function is central to your needs, the B01 Chronograph 43 (AB0138) is the balanced choice — mid-size, in-house movement and the full slide rule. Larger wrists should consider the 46mm (AB0127) for improved bezel readability. If you prefer a cleaner dial and slimmer profile, the Automatic 41 (A17326) drops the chronograph registers while keeping the Navitimer aesthetic. Space and aviation history enthusiasts should explore the Cosmonaute (AB0210) with its 24-hour dial and manual-wind caliber. For Breitling’s dedicated dive line, see the Superocean. For a versatile sport chronograph without the aviation focus, explore the Chronomat.

Frequently Asked Questions

How does the Navitimer slide rule bezel work?

The slide rule is a circular version of the E6B flight computer. Two logarithmic scales — one on the rotating outer bezel and one fixed on the inner dial ring — allow multiplication, division and unit conversion through relative positioning. To multiply, align the first number on the outer scale with the index mark, then read the product opposite the second number. Pilots use it for fuel consumption calculations (gallons per hour times flight time), airspeed conversions (knots to mph), climb or descent rate planning and distance-time-speed relationships. Over 420 graduation marks are machined into the two scales for precision.

What is the difference between Navitimer 43 and 46?

Both use the identical B01 in-house caliber with column-wheel, vertical clutch and 70-hour power reserve. The difference is size: 43mm versus 46mm diameter, affecting case thickness (13.6mm vs 14.5mm), lug-to-lug distance and visual dial proportions. The 46mm provides better slide rule legibility due to larger scale spacing. The 43mm offers more balanced proportions on average wrists (6.5 to 7.5 inches). Dial layouts are identical — three registers with running seconds, 30-minute counter and 12-hour counter. Both are available in the same dial color options.

What makes the Cosmonaute different from standard Navitimers?

The Cosmonaute features a 24-hour dial instead of the standard 12-hour layout. The hour hand completes one full rotation in 24 hours, displaying morning and evening on the same dial face. This was designed for orbital spaceflight, where day and night cycles are 90 minutes long and a 12-hour dial becomes disorienting. Additionally, the Cosmonaute uses the B02 manual-wind caliber rather than the B01 automatic, requiring daily winding. The manual wind was chosen for the original 1962 model because automatic winding does not function in zero gravity.

What is COSC chronometer certification?

COSC (Controle Officiel Suisse des Chronometres) is an independent Swiss testing body. Each movement is tested individually over 15 days in 5 positions and at 3 temperatures. The standard requires daily rate accuracy between -4 and +6 seconds per day. All Breitling B01, B02 and B20 movements carry COSC certification. This is an individual movement test, not a batch sample — every caliber leaving the Breitling factory has its own COSC certificate with serial number and measured rate results.

How does the Navitimer compare to the IWC Pilot’s Chronograph?

Both are pilot’s chronographs from established Swiss manufactures. The Navitimer’s defining feature is the circular slide rule bezel — a functional flight computer absent on the IWC. The IWC Pilot’s Chronograph uses a cleaner dial with a soft iron inner cage for antimagnetic protection. Movement-wise, the Navitimer B01 is fully in-house (column-wheel, 70-hour reserve), while the IWC 69385 is also in-house with 46-hour reserve. Visually, the Navitimer is busier and more instrument-like; the IWC is more legible and minimalist. The Navitimer runs 43mm or 46mm; the IWC standard is 41mm or 43mm.
