1. Best Overall — Sapin Chevre Slim Strap
Every watch needs a go-to strap, and for the Montblanc Star Legacy Automatic Date 42, this is it.
The Sapin 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 Montblanc Star Legacy Automatic Date 42's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 9.53mm case thickness means a padded strap like this one feels proportional and substantial.
Simple, effective, and genuinely enjoyable to wear.

2. Best Dressy — Matte Orange Alligator Signature Strap
When you need to dress the Montblanc Star Legacy Automatic Date 42 up, this is the strap that delivers.
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.
On the Montblanc Star Legacy Automatic Date 42, this strap preserves the watch's go-anywhere character. The 42mm case at 9.53mm thick pairs naturally with the padded construction without creating any imbalance on the wrist.

3. Best Everyday — Chestnut Buttero Chunky Strap
For daily wear, comfort and versatility matter more than anything else.
The Chestnut Buttero Chunky 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 3.0mm thick, it balances presence and wearability nicely.

A Note on Buckle Colour
Quick but important: always match your buckle to your case. The Montblanc Star Legacy Automatic Date 42'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 Montblanc Star Legacy Automatic Date 42
Swapping straps on the Montblanc Star Legacy Automatic Date 42 is one of the easiest upgrades you can make — and with Delugs straps, you don't even need a tool.
If your Montblanc Star Legacy Automatic Date 42 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 Montblanc Star Legacy Automatic Date 42 uses a standard 22mm lug width, and all Delugs straps in 22mm will fit perfectly.
