1. Best Overall — Colibri Chevre Slim Strap
If you're buying your first aftermarket strap for the Breitling Galactic 36, this is where I'd start.
The Colibri 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 Galactic 36, this strap preserves the watch's go-anywhere character. The 36mm case at 12.3mm thick pairs naturally with the padded construction without creating any imbalance on the wrist.
It's the kind of pairing that makes you wonder why you didn't try it sooner.
Other colours worth considering:
- Light Grey Chevre Slim Strap
- Lavender Chevre Slim Strap
- Gold Chevre Slim Strap
- Red Chevre Slim Strap
2. Best Dressy — Matte Oatmeal Alligator Signature Strap
When you need to dress the Breitling Galactic 36 up, this is the strap that delivers.
The Matte Oatmeal Alligator Signature Strap is crafted from genuine alligator leather — not embossed calfskin, the real thing. Each scale pattern is unique, and the matte finish gives it a refined presence that catches light without being flashy. The leather is supple from the start with minimal break-in needed. At 4.5–2.2mm thick, it balances presence and wearability nicely.

3. Best Everyday — Navy Pueblo Slim Strap
For daily wear, comfort and versatility matter more than anything else.
The Navy Pueblo Slim 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 2.2mm thick, it balances presence and wearability nicely.
Paired with the Breitling Galactic 36's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 12.3mm case thickness means a padded strap like this one feels proportional and substantial.
It's the kind of pairing that makes you wonder why you didn't try it sooner.
Other colours worth considering:
- Grigio Pueblo Slim Strap
- Dark Brown Pueblo Slim Strap
- Natural Pueblo Slim Strap
- Cognac Pueblo Slim Strap
4. Best Minimalist — Natural Shell Cordovan Slim Strap
Strip away the unnecessary and what's left is pure design. That's this strap.
The Natural Shell Cordovan Slim Strap is crafted from premium materials with careful attention to detail and construction quality. At 2.2mm thick, it balances presence and wearability nicely.
The Breitling Galactic 36's 36mm 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.

5. Best Casual — Dark Brown Rubberised Leather (Togo) Signature Strap
For those days when the Breitling Galactic 36 comes out with jeans and a t-shirt.
The Dark Brown Rubberised Leather (Togo) Signature Strap uses rubberised leather — a material that blends the look and feel of leather with the water resistance and durability of rubber. The smooth finish is clean and modern, and the pastel colour options add a playful element to otherwise serious watches. At 4.5–2.2mm thick, it balances presence and wearability nicely.

6. Best Sporty — White Mosaic CTS Rubber Strap
A sportier option that brings comfort and durability without sacrificing style.
The White 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.
What makes this pairing work on the Breitling Galactic 36 is the contrast — the refined case finishing against the texture creates visual interest without conflict. With a 36mm case, the proportions stay balanced.
A combination that's greater than the sum of its parts.

7. The Wildcard — Blue Jean Ostrich Leg Signature Strap
Every rotation needs a curveball. This is mine.
The Blue Jean 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.

A Note on Buckle Colour
Quick but important: always match your buckle to your case. The Breitling Galactic 36's Stainless steel 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 Galactic 36
Swapping straps on the Breitling Galactic 36 is one of the easiest upgrades you can make — and with Delugs straps, you don't even need a tool.
If your Breitling Galactic 36 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 Galactic 36 uses a standard 18mm lug width, and all Delugs straps in 18mm will fit perfectly.
