1. Best Overall — Bordeaux Chevre Slim Strap
There's a reason this is the number one pick — it just works.
The Bordeaux 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.
What makes this pairing work on the Baltic Hermétique Tourer is the contrast — the refined case finishing against the texture creates visual interest without conflict. With a 37mm case, the proportions stay balanced.
Once you see it on the wrist, it just clicks.
The range goes deeper if you want to explore:
- Light Grey Chevre Slim Strap
- Colibri Chevre Slim Strap
- Lavender Chevre Slim Strap
- Gold Chevre Slim Strap
2. Best Dressy — Matte Black Alligator Signature Strap
There's dressy, and then there's refined. This strap lands squarely in refined territory.
The Matte Black 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 Baltic Hermétique Tourer's 37mm 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:
- Matte Navy Alligator Signature Strap
- Matte Himalayan Alligator Signature Strap
- Matte Mahogany Alligator Signature Strap
- Matte Dark Brown Alligator Signature Strap
3. Best Everyday — Nubuck Black Ostrich Leg Signature Strap
Your daily strap should feel invisible on the wrist. This one gets close.
The Nubuck Black Ostrich Leg Signature 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 4.5–2.2mm thick, it balances presence and wearability nicely.
The Baltic Hermétique Tourer's 37mm 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.
A combination that's greater than the sum of its parts.
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.

5. Best Casual — Maroon Crazy Horse Side-Stitch Strap
Casual doesn't mean careless — this strap adds character without trying too hard.
The Maroon Crazy Horse Side-Stitch 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 2.5mm thick, it balances presence and wearability nicely.
Paired with the Baltic Hermétique Tourer's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 10.8mm case thickness means a padded strap like this one feels proportional and substantial.
A combination that's greater than the sum of its parts.
Worth a look in other colourways:
- Black Crazy Horse Side-Stitch Strap
- Mocha Crazy Horse Side-Stitch Strap
- Tan Crazy Horse Side-Stitch Strap
- Cognac Crazy Horse Side-Stitch Strap
6. Best Sporty — Baby Blue Tropical CTS Rubber Strap
Casual energy with a sportier edge. This strap shifts the mood without going full tool-watch.
The Baby Blue Tropical 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 Baltic Hermétique Tourer's 37mm 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.

A Note on Buckle Colour
Quick but important: always match your buckle to your case. The Baltic Hermétique Tourer's 316L 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 Baltic Hermétique Tourer
Swapping straps on the Baltic Hermétique Tourer is one of the easiest upgrades you can make — and with Delugs straps, you don't even need a tool.
If your Baltic Hermétique Tourer 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 Baltic Hermétique Tourer uses a standard 20mm lug width, and all Delugs straps in 20mm will fit perfectly.
