Breitling Navitimer sizes: 32, 36, 41, 43 or 46mm, which to buy? (2026)

For most people, the best Breitling Navitimer is the B01 Chronograph in 43mm: Breitling's own movement with a 70-hour power reserve. For smaller wrists, the same watch in 41mm. For much less, the Navitimer Automatic keeps the famous slide-rule bezel without the chronograph.

Every watch here is sold new by Goldsmiths, a UK authorised Breitling retailer. Prices are Goldsmiths' own on the date shown.

How we chose

We went through the Navitimers Goldsmiths has in stock, more than 70 of them, and read Breitling's own product pages for every size: the calibre, power reserve, thickness and water resistance. Breitling doesn't list lug-to-lug on the pages we read, so we haven't guessed one. We earn a commission if you buy through our links, which never changes the price you pay.

Every Navitimer size compared

Figures are Breitling's own, from its product pages; prices are Goldsmiths' for the version shown, on an alligator strap (a steel bracelet costs a little more).

Two things stand out. The B01 is the same watch in three sizes, with almost the same thickness, so choose by wrist, not by features. And the Automatic is much slimmer, under 12mm, because it has no chronograph.

Which Navitimer size for your wrist?

As a rough guide, by wrist measurement (all the way round):

• Under about 16cm: the 32mm or 36mm.
• About 16cm to 17.5cm: the 41mm, B01 or Automatic.
• About 17.5cm to 19cm: the 43mm B01.
• Over about 19cm: the 43mm or 46mm.

The Navitimer has a big dial and a thin bezel, so it can look larger than other watches of the same diameter. If you're between sizes, choose the smaller one. Our watch size calculator suggests a case size from your wrist.

The best Navitimer overall: B01 Chronograph 43

The classic Navitimer. According to Goldsmiths' description, the Navitimer, short for "navigation timer", was first introduced in 1952 for pilots to do their flight calculations in the air, and two years later became the official watch of the Aircraft Owners and Pilots Association (AOPA), whose wings sit at 12 o'clock on the dial. The B01 Chronograph has the rotating slide-rule bezel and a stopwatch, powered by Breitling's own calibre 01 with a 70-hour power reserve, according to Breitling. Goldsmiths lists it with a 5-year guarantee.

Strap or bracelet? The steel bracelet costs about £200 more at Goldsmiths. The 43mm comes in black, blue, copper, mint green and silver.

The best Navitimer for smaller wrists: B01 Chronograph 41

The same B01 Chronograph, with the same calibre 01 and 70-hour power reserve, in a 41mm case. Breitling gives it 13.6mm thick, against 13.69mm for the 43mm, so the difference is all in the width. When we checked, Goldsmiths' prices for the two sizes were within £50 of each other.

The best value Navitimer: Navitimer Automatic 41

The slide-rule bezel and the Navitimer look, without the chronograph, for much less. Breitling lists the Breitling 17 automatic with a 38-hour power reserve, and at 11.65mm it's about 2mm slimmer than the B01, so it slides under a cuff more easily. Goldsmiths lists it with a 2-year guarantee, against 5 years for the B01.

The biggest Navitimer: B01 Chronograph 46

The B01 in 46mm, for large wrists only. Breitling gives it 13.95mm thick, barely more than the 41mm, so it's wide rather than tall.
