1. Best Overall — Gold Chevre Slim Strap
Every watch needs a go-to strap, and for the Oris Roberto Clemente, this is it.
The Gold 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.
Paired with the Oris Roberto Clemente's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 13.5mm 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:
- Light Grey Chevre Slim Strap
- Colibri Chevre Slim Strap
- Lavender Chevre Slim Strap
- Red Chevre Slim Strap
2. Best Dressy — Matte Orange Alligator Signature Strap
The Oris Roberto Clemente cleans up remarkably well — and this strap is the reason.
The Matte Orange 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 Oris Roberto Clemente is the contrast — the refined case finishing against the texture creates visual interest without conflict. With a 43.5mm case, the proportions stay balanced.
A combination that's greater than the sum of its parts.
Worth a look in other colourways:
- Matte Black Alligator Signature Strap
- Matte Navy Alligator Signature Strap
- Matte Himalayan Alligator Signature Strap
- Matte Mahogany Alligator Signature Strap
3. Best Everyday — Natural Buttero Slim Strap
For daily wear, comfort and versatility matter more than anything else.
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.
Paired with the Oris Roberto Clemente's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 13.5mm 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:
- Chestnut Buttero Slim Strap
- Brown Buttero Slim Strap
- Taupe Buttero Slim Strap
- Green Buttero Slim Strap
4. Best Minimalist — Navy Shell Cordovan Slim Strap

The Navy 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 Oris Roberto Clemente's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 13.5mm case thickness means a padded strap like this one feels proportional and substantial.

The Oris Roberto Clemente's 43.5mm 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.

6. Best Sporty — Olive Green Mosaic CTS Rubber Strap
Not every sporty strap needs to be water-resistant — sometimes it is about the texture and attitude.
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.
Paired with the Oris Roberto Clemente's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 13.5mm case thickness means a padded strap like this one feels proportional and substantial.

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