Grand Seiko has always been about quiet mastery — the kind of watchmaking that reveals itself the closer you look. The Quartz SBGV235 (ref. SBGV235) is a perfect example. The finishing and attention to detail speak for themselves. With a 19mm lug width, it takes aftermarket straps beautifully.
The 39mm case with its 10.4mm profile gives you just enough wrist presence to anchor different strap materials without the watch disappearing. Here are my 7 picks — and why each one works.

1. Best Overall — Taupe Epsom Strap for Cartier Tank
Your first strap upgrade should feel like an obvious improvement. This one does.
The Taupe Epsom Strap for Cartier Tank 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.
The Grand Seiko Quartz SBGV235's 39mm 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.
Once you see it on the wrist, it just clicks.
2. Best Dressy — Matte Grey Storm Alligator Strap for Cartier Tank
There's dressy, and then there's refined. This strap lands squarely in refined territory.
The Matte Grey Storm Alligator Strap for Cartier Tank 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 2.2mm thick, it balances presence and wearability nicely.

Worth a look in other colourways:
3. Best Everyday — Navy Pueblo Slim Strap
For daily wear, comfort and versatility matter more than anything else.
The Navy Pueblo 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 Grand Seiko Quartz SBGV235's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 10.4mm case thickness means a padded strap like this one feels proportional and substantial.

5. Best Casual — Grey Rubberised Leather (Togo) Strap for Cartier Tank
Weekend straps should feel effortless. This one nails that.
The Grey Rubberised Leather (Togo) Strap for Cartier Tank 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 2.2mm thick, it balances presence and wearability nicely.

6. Best Sporty — Navy Waffle CTS Rubber Strap
Active wear demands a strap that can handle sweat and splashes. This one does.
The Navy Waffle 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 Grand Seiko Quartz SBGV235's distinctive dial, this strap adds a layer of personality that the factory option does not offer. The 10.4mm case thickness means a padded strap like this one feels proportional and substantial.
Simple, effective, and genuinely enjoyable to wear.

7. The Wildcard — Sand Alcantara Signature Strap
This one's different — and that's exactly the point.
The Sand Alcantara Signature Strap is crafted from Alcantara — the same Italian material used in luxury car interiors and high-end sportswear. It has a suede-like softness that is immediately comfortable, with a luxurious hand feel that belies its toughness. At 4.5–2.2mm thick, it balances presence and wearability nicely.
On the Grand Seiko Quartz SBGV235, this strap preserves the watch's go-anywhere character. The 39mm case at 10.4mm thick pairs naturally with the padded construction without creating any imbalance on the wrist.
Simple, effective, and genuinely enjoyable to wear.

A Note on Buckle Colour
Quick but important: always match your buckle to your case. The Grand Seiko Quartz SBGV235'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 Grand Seiko Quartz SBGV235
Swapping straps on the Grand Seiko Quartz SBGV235 is one of the easiest upgrades you can make — and with Delugs straps, you don't even need a tool.
If your Grand Seiko Quartz SBGV235 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 Grand Seiko Quartz SBGV235 uses a standard 19mm lug width, and all Delugs straps in 19mm will fit perfectly.
