Yes, I actually use the slide rule
By Rafael Ortiz, Mexico City ยท
People laugh when I say this, but the slide rule on a Navitimer still works. Fuel burn, ground speed, unit conversions. The circular computer was designed for pilots in 1952, when Breitling partnered with AOPA, and once you learn it you can do rough math faster than you can find the calculator on your phone.
This 41 mm version is the one I'd recommend for most wrists. It's 13.6 mm thick on 20 mm lugs, and the black dial with silver subdials has that classic, busy look. Busy is the honest word. With the slide rule scale, the tachymeter-style numbers and the date, legibility is not as instant as on a simpler chronograph. You learn to read it.
The B01 is excellent and the pushers have a lovely snap. What really bothers me is the 30 meter water resistance, which for 9,050 to 9,800 dollars feels stingy. A leather strap and 30 m means this is a watch for the flight deck and the restaurant, not the pool.
If you're a pilot, or love the idea of being one, this is the Navitimer to buy.
