1. Best Overall — Navy Saffiano Signature Strap
Every watch needs a go-to strap, and for the TAG Heuer Formula 1, this is it.
The Navy Saffiano Signature Strap uses saffiano leather — that signature cross-hatch embossed pattern you see on high-end bags and accessories. It is remarkably scratch-resistant and handles moisture better than most leathers, which makes it one of the most practical premium options you can put on a watch. At 4.5–2.2mm thick, it balances presence and wearability nicely.
Paired with the TAG Heuer Formula 1's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The case thickness means a padded strap like this one feels proportional and substantial.
Once you see it on the wrist, it just clicks.
The range goes deeper if you want to explore:
2. Best Dressy — Matte Navy Alligator Signature Strap
The TAG Heuer Formula 1 cleans up remarkably well — and this strap is the reason.
The Matte Navy 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.
What makes this pairing work on the TAG Heuer Formula 1 is the contrast — the refined case finishing against the texture creates visual interest without conflict. With a case, the proportions stay balanced.
Worth a look in other colourways:
- Matte Black Alligator Signature Strap
- Matte Himalayan Alligator Signature Strap
- Matte Mahogany Alligator Signature Strap
- Matte Dark Brown Alligator Signature Strap
3. Best Everyday — Dark Brown Nubuck Slim Strap
An everyday strap needs to be comfortable from the jump and work with most of what you wear.
The Dark Brown Nubuck Slim Strap is crafted from nubuck leather — soft, velvety to the touch, and comfortable from the first wear. No break-in period needed. The suede-like texture adds a casual warmth that takes the edge off a formal watch without losing sophistication. At 2.2mm thick, it balances presence and wearability nicely.
On the TAG Heuer Formula 1, this strap preserves the watch's go-anywhere character. The case pairs naturally with the padded construction without creating any imbalance on the wrist.

- Navy Nubuck Slim Strap

4. Best Minimalist — Natural Shell Cordovan Slim Strap
Minimalism isn't about doing less. It's about doing exactly what's needed.
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.
Paired with the TAG Heuer Formula 1's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The case thickness means a padded strap like this one feels proportional and substantial.
The kind of strap that earns a permanent spot in your rotation.
If this style appeals but you want a different tone:
- Black Shell Cordovan Slim Strap
- Navy Shell Cordovan Slim Strap
- Cognac Shell Cordovan Slim Strap
- Green Shell Cordovan Slim Strap
5. Best Casual — Navy Rubberised Leather (Togo) Signature Strap
For those days when the TAG Heuer Formula 1 comes out with jeans and a t-shirt.
The Navy 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.
On the TAG Heuer Formula 1, this strap preserves the watch's go-anywhere character. The case pairs naturally with the padded construction without creating any imbalance on the wrist.
Other colours worth considering:
- Black Rubberised Leather (Togo) Signature Strap
- Colibri Rubberised Leather (Togo) Signature Strap
- Hunter Green Rubberised Leather (Togo) Signature Strap
- Taupe Rubberised Leather (Togo) Signature Strap
6. Best Sporty — Grey Mosaic CTS Rubber Strap
A sportier option that brings comfort and durability without sacrificing style.
The Grey 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 TAG Heuer Formula 1 is the contrast — the refined case finishing against the texture creates visual interest without conflict. With a case, the proportions stay balanced.

7. The Wildcard — Copper Ostrich Leg Signature Strap
Think of this as the strap you didn't know you needed.
The Copper 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.
The TAG Heuer Formula 1's 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.
Simple, effective, and genuinely enjoyable to wear.

- Blue Jean Ostrich Leg Signature Strap
- Tapestry Grey Ostrich Leg Signature Strap
- Dark Grey 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 TAG Heuer Formula 1's 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 TAG Heuer Formula 1
Swapping straps on the TAG Heuer Formula 1 is one of the easiest upgrades you can make — and with Delugs straps, you don't even need a tool.
If your TAG Heuer Formula 1 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 TAG Heuer Formula 1 uses a standard 18mm lug width, and all Delugs straps in 18mm will fit perfectly.
