Breitling has always been about building instruments for professionals — whether pilots, divers, or anyone who demands precision. The Navitimer B01 (ref. BREITLING NAVITIMER) is a perfect example. The finishing and attention to detail speak for themselves. With a 22mm lug width, it takes aftermarket straps beautifully.
The case measures 41mm with a thickness of ~13.6mm — proportions that sit comfortably on most wrists without dominating them. It strikes that balance between presence and wearability that makes it suited to almost any strap.
Here are my 7 picks — and why each one works.

1. Best Overall — Red Chevre Slim Strap
If you're buying your first aftermarket strap for the Breitling Navitimer B01, this is where I'd start.
The Red Chevre Slim Strap is made from chevre (goatskin) leather, sourced from the Alran tannery. The natural pebbled grain is finer than Epsom and slightly shiny — it looks luxurious without trying too hard. Chevre is also impressively water and scratch resistant for a natural leather. At 2.2mm thick, it balances presence and wearability nicely.
On the Breitling Navitimer B01, this strap preserves the watch's go-anywhere character. The 41mm case at ~13.6mm thick pairs naturally with the padded construction without creating any imbalance on the wrist.
A combination that's greater than the sum of its parts.
Worth a look in other colourways:
- Light Grey Chevre Slim Strap
- Colibri Chevre Slim Strap
- Lavender Chevre Slim Strap
- Gold Chevre Slim Strap
2. Best Dressy — Glossy Saffron Crocodile Signature Strap
When you need to dress the Breitling Navitimer B01 up, this is the strap that delivers.
The Glossy Saffron Crocodile Signature Strap is made from genuine crocodile leather with a distinctive scale pattern that no embossed leather can replicate. The texture adds visual depth and character that works equally well with a suit or a smart-casual outfit. At 4.5–2.2mm thick, it balances presence and wearability nicely.
On the Breitling Navitimer B01, this strap preserves the watch's go-anywhere character. The 41mm case at ~13.6mm thick pairs naturally with the padded construction without creating any imbalance on the wrist.

3. Best Everyday — Natural Buttero Chunky Strap
The strap you reach for without thinking — that's what an everyday pick should be.
The Natural Buttero Chunky Strap features Buttero leather from the Walpier tannery in Italy. This vegetable-tanned leather develops one of the most beautiful patinas in watchmaking — scratches blend into the surface and the colour deepens over time. If you enjoy watching your strap age gracefully, this is the one. At 3.0mm thick, it balances presence and wearability nicely.
What makes this pairing work on the Breitling Navitimer B01 is the contrast — the refined case finishing against the texture creates visual interest without conflict. With a 41mm case, the proportions stay balanced.
The kind of strap that earns a permanent spot in your rotation.
If this style appeals but you want a different tone:
4. Best Minimalist — Navy Shell Cordovan Slim Strap

5. Best Casual — Black Crazy Horse Chunky Strap
For those days when the Breitling Navitimer B01 comes out with jeans and a t-shirt.
The Black Crazy Horse Chunky Strap uses crazy horse leather — an oil-infused leather that develops character with every scratch and mark. Rub a scratch with your thumb and it blends right back in. It is built for people who actually wear their watches, not baby them. At 3.0mm thick, it balances presence and wearability nicely.

6. Best Sporty — Olive Green Mosaic CTS Rubber Strap
Casual energy with a sportier edge. This strap shifts the mood without going full tool-watch.
The Olive Green Mosaic CTS Rubber Strap is made from FKM rubber — a high-performance elastomer that resists chemicals, heat, and ageing. Unlike silicone, it does not attract dust or lint. Cut-to-size construction means you trim it to your exact wrist measurement — no leftover tail, no keepers. At 4.0–3.3mm thick, it balances presence and wearability nicely.
The Breitling Navitimer B01's 41mm case is ideally proportioned for this strap. Whether you are wearing it casually or dressing it up, the combination feels intentional. It is the kind of pairing where both the watch and strap look better together than apart.
Other colours worth considering:
7. The Wildcard — Dark Grey Ostrich Leg Signature Strap
Every rotation needs a curveball. This is mine.
The Dark Grey Ostrich Leg Signature Strap is made from ostrich leg leather. Unlike the body leather, ostrich leg has a distinctive scale-like texture with natural ridges and patterns that give it an almost reptilian character. It is soft, supple, and needs virtually no break-in time. At 4.5–2.2mm thick, it balances presence and wearability nicely.
What makes this pairing work on the Breitling Navitimer B01 is the contrast — the refined case finishing against the texture creates visual interest without conflict. With a 41mm case, the proportions stay balanced.
Other colours worth considering:
- Blue Jean Ostrich Leg Signature Strap
- Tapestry Grey Ostrich Leg Signature Strap
- Copper Ostrich Leg Signature Strap
- Forest Green Ostrich Leg Signature Strap
A Note on Buckle Colour
Quick but important: always match your buckle to your case. The Breitling Navitimer B01's Stainless steel (brushed/polished) case calls for a silver (brushed or polished) buckle. All Delugs leather straps ship with a pin buckle and can be upgraded to a Spring Deployant Clasp for extra security and convenience. All Delugs straps come with quick-release spring bars pre-installed, so swapping straps takes seconds.
How to Change the Strap on Your Breitling Navitimer B01
Swapping straps on the Breitling Navitimer B01 is one of the easiest upgrades you can make — and with Delugs straps, you don't even need a tool.
If your Breitling Navitimer B01 came on a bracelet, you'll first need to remove it. The easiest way to do this at home is with a Bracelet Removal Tool, which lets you compress the spring bars without risking scratches to the lugs or caseback. Once the bracelet is off, you can slide your new Delugs strap straight in.
All Delugs straps come with quick-release spring bars already pre-installed, so changing straps is completely tool-free. Here's how:
- Prepare your workspace. Lay the watch face-down on a soft cloth or microfiber pad to protect the caseback from scratches.
- Release the spring bar. Locate the small lever on the quick-release spring bar. Pull it back with your fingernail or fingertip to compress the bar.
- Remove the strap. While holding the lever, angle the strap out from between the lugs. Repeat for the other side.
- Insert the new strap. Slide one end of the spring bar into the lug hole. Pull the lever on the quick-release spring bar knob, guide the entire spring bar into the opposite lug hole, and then release the knob. You should hear a small click when the spring bar extends and seats into the lug hole.
- Check the fit. Give the strap a gentle tug to make sure both spring bars are securely locked in. If there's any play, reseat the spring bar.
The entire process takes under a minute once you get the hang of it — no spring bar tool required. The Breitling Navitimer B01 uses a standard 22mm lug width, and all Delugs straps in 22mm will fit perfectly.
