Can a slide rule bezel still work at 36mm? This Breitling Navitimer Automatic 36 replica brings the legendary circular slide rule bezel to a smaller case format specifically designed for women. The A17327381B1P1 reference pairs an anthracite sunburst dial with silver-tone baton markers, keeping the signature Navitimer calculation ring intact while giving the small case a quiet, grown-up look. The crocodile leather strap in a muted neutral tone adds warmth and texture that no metal bracelet can deliver at this compact diameter. Despite the reduced scale, the bezel markings remain legible and functional. There is no date on this dial, so the anthracite face stays symmetrical from 12 to 6; for styling ideas, see our notes on ways to wear a Navitimer.

Anthracite Sunburst with Plain Baton Markers

The baton markers are the same stick indices found on larger Navitimer references, scaled down to suit the smaller dial. Each one is polished so it catches light at multiple angles, giving the dial visual depth against the brushed anthracite surface beneath. The interplay between the bright markers and the grey sunburst creates a dial that shifts character throughout the day, from near-black indoors to a lighter slate in daylight.

Breitling Navitimer Automatic 36 Replica with a Full Slide Rule

Navitimer watches above 40mm dominate secondary markets, so this 36mm version occupies a distinctly quieter space among enthusiasts. Collectors who track the full range know that the small Navitimers, the 35 and this A17327381B in 36mm, keep the slide rule bezel rather than replacing it with a plain fluted ring. The crocodile strap ages distinctively with wear, developing a patina over time that bracelet-equipped models simply never achieve. For a broader look at the lineup, browse the Navitimer collection, or compare directly with the 41mm ice blue Navitimer GMT A32310171C1P1 for a larger unisex alternative with a second time zone, worn on a blue alligator strap.

36mm Anthracite Next to the 35mm Navitimers

Where 41mm and 46mm Navitimers command wrist presence through sheer diameter, this 36mm reference achieves the same heritage identity in a package that sits flat under a shirt cuff. Its anthracite dial carries no date and no decoration beyond the scales, which makes it the understated choice among the small Navitimers and an easy one to wear with grey, navy or black clothes. So the answer to the opening question is yes: the scales are smaller, but the bezel turns, the numbers stay readable, and the case is slim enough for everyday rotation.
