1. Best Overall — Hunter Green Epsom Slim Strap
If you're buying your first aftermarket strap for the Timex Expedition North, this is where I'd start.
The Hunter Green Epsom Slim Strap features Epsom leather, tanned by Haas. The fine, uniform grain gives it a clean, contemporary look that resists scratches and moisture with ease. This is leather that looks as sharp six months from now as it does on day one. At 2.2mm thick, it balances presence and wearability nicely.
On the Timex Expedition North, this strap preserves the watch's go-anywhere character. The case at thick pairs naturally with the padded construction without creating any imbalance on the wrist.
Simple, effective, and genuinely enjoyable to wear.

- Black Epsom Slim Strap
- Tinware Grey Epsom Slim Strap
- Izmir Blue Epsom Slim Strap
- Orange Epsom Slim Strap
2. Best Dressy — Matte Dolphin Grey Alligator Signature Strap
There's dressy, and then there's refined. This strap lands squarely in refined territory.
The Matte Dolphin Grey 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.
The Timex Expedition North'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.
If this style appeals but you want a different tone:
- Matte Black Alligator Signature Strap
- Matte Navy Alligator Signature Strap
- Matte Himalayan Alligator Signature Strap

3. Best Everyday — Natural Buttero Slim Strap
Your daily strap should feel invisible on the wrist. This one gets close.
The Natural Buttero 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.

5. Best Casual — Taupe Rubberised Leather (Togo) Signature Strap
Not every strap needs to make a statement. Sometimes relaxed is the right move.
The Taupe 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 — Red Mosaic CTS Rubber Strap
A sportier option that brings comfort and durability without sacrificing style.
The Red 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.

Other colours worth considering:
7. The Wildcard — Serpentine Ostrich Leg Signature Strap
This one's different — and that's exactly the point.
The Serpentine 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.
On the Timex Expedition North, this strap preserves the watch's go-anywhere character. The case at thick pairs naturally with the padded construction without creating any imbalance on the wrist.
Once you see it on the wrist, it just clicks.

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