Bonetto Cinturini 315 Rubber Watch Strap - Black
Made in Italy from vulcanized NBR rubber. Waterproof, UV-resistant, and nonallergenic.
Rather than relying on waves or cutouts, Model 315 uses shallow beveled embossing to give the strap definition. The angled detailing runs along the top surface and catches light just enough to add depth, while the overall profile stays slim and controlled. Visually, it reads quieter and more refined than most traditional dive straps. This design is about restraint. The slimmer build and softened geometry make it a good match for modern sports watches and everyday tool watches where rubber is appropriate, but heavy dive styling would feel out of place. Double keepers add stability without disrupting the clean lines.
Material & feel
Vulcanized nitrile butadiene rubber (NBR) is used for its durability, flexibility, and resistance to seawater and sunlight. The vulcanization process gives the strap structure while preserving an easy, natural bend, so it wears comfortably without feeling soft or floppy.
On the wrist, Model 315 feels light and composed. The beveled embossing adds surface interest without stiffness, and the textured underside helps reduce surface contact, improving airflow during extended wear. Compared to more sculpted Bonetto models, this one feels smoother and more understated.
Carries a light vanilla scent, typical of Italian-made vulcanized rubber.

I chose the Bonetto Cinturini 315 rubber strap for my Seiko Turtle Save the Ocean, and I couldn’t be happier with the choice. It looks like it was made specifically for the watch. The strap’s shape, proportions, and overall design complement the Turtle’s large case and dive-watch character extremely well.
Compared with the stock Seiko silicone strap, the Bonetto 315 feels like a significant upgrade. The Bonetto has a more substantial, refined appearance and gives the watch a much more finished look. It also sits nicely against the case and looks particularly well suited to the Turtle’s rugged design.
What I especially like is that the Bonetto doesn’t try to make the Turtle look like something it isn’t. It preserves the tool-watch character while making the watch feel more substantial and better put together. The stock silicone strap is perfectly functional, but the Bonetto 315 looks and feels like a better match for the watch.
For my Seiko Turtle, choosing the Bonetto Cinturini 315 was definitely the right decision. It complements the watch beautifully and, in my opinion, is a noticeable improvement over the original strap
Ordered this to replace the bulky oem strap for my Panerai submersible, and what a difference. So much more refined and comfortable. This strap is the perfect thickness, not too thick, not too thin.
Incredible quality for the price. Vanilla smell was a bit strong for me initially but after washing with some baking soda, smell is a lot more manageable.
Holbens customer service is absolutely stellar as well— quick shipping, quick responses etc. would buy again from here.
Extremely fast delivery!
A first class experience.
This strap smells like heaven.😎
It is very elegant strap, can be used with both sports and dressed watch. It has thin profile with a solid feel and does not attract lint/dust. The underneath dotted pattern keeps the airflow and less sweaty. Most comfortable strap I have ever used. Mild vanilla scent is an added bonus. I have 6-3/4 inch (6.75") wrist and it fits perfectly to the second last hole from the clasp with 42mm watch.
Add-on black clasp is worth spending few extra bucks. It has brushed/matte look, strong feel and matches perfectly with the strap.
Excellent customer service, they know their stuff pretty well.
I dove (pun intended) into researching the best rubber straps I can pair with my dive watches. You’ll often see FKM rubber or silicone straps from other brands. Don’t bother with those. Bonetto Cinturini uses vulcanized rubber that has the one-of-a-kind sweet smell. Love that it doesn’t attract lint like the other cheaper options!
Great strap. Fast shipping and exactly as described.
Fantastic strap and service. This one is certainly a keeper. Thanks again!
very nice dive band

After choosing a cheap $10 Silicone strap I had no choice but to try again as it turns out that Silicone retains static electricity and I have a sensitivity issue. My new model 315 strap arrived today and I was impressed that it came with a much thicker, stronger and better-looking Pin Buckle clasp. I wore it for three hours tonight and it felt good on the wrist with no allergic reaction. The strap has a cool looking design pattern and I only wish that Bonetto made a curved end model that form-fitted to the case of my Seiko Turtle so as to not leave a gap. All said and done this strap is just as comfortable as the much more expensive one found on the Oris Aquis, and the Vanilla Scent is just as awesome! One more hold is needed if you have a six-inch wrist, but the Watch does not roll over as manufactured. $32 well spent!
Good well made strap but be aware of the rather strong vanilla smell. I thought I could get used to it but I can't. I got rid of it after a few weeks
Thank you for the review. Bonetto Cinturini straps have a light vanilla scent, which can be more noticeable for those who are sensitive to it.
Fits my Victorinox Dive Master 500. VERY comfortable. Somewhat aerodynamic, and sleeker design than most. Makes wearing the watch less like work, and more akin to a pleasant experience.
Needed a new strap for a 22mm dive watch, found this one and took a chance. Amazed at the quality, had recently purchased a similar strap for over twice the price - I truly believe it's the same strap!
The underside (skin side) has a textured surface that allows moisture (perspiration) to escape. Clasp and keepers are quality, all in all an excellent product from a very fair seller.
I purchased this band for warm weather activities like hiking, so I don't have to worry about sweat ruining anything. This band is very comfortable even when it's hot out, and it looks great. It's a good length for smaller, sub-7 inch wrists like mine, and I like how it doesn't attract dust or lint like the silicone bands do. Great band!
I have been very pleased with this brand of watch bands. In my opinion, Bonetto Cinturini makes the nicest rubber watch bands. I have tried others and none compare. Lint or dust does not stick to these watch bands and they stay looking new for a long time. This particular model number is my favorite. It's very classy, understated and versatile. I have used it with a dressier watch and a dive watch. It looks equally great on either one. This rubber watch band is particularly nice for those with smaller wrists. As it has a very thin profile and I was able to easily cut some length for a perfect fit. It also has a nice vanilla scent to it. Which to me, is nicer than a rubber or plastic smell. It may be strong to some who are sensitive and/or don't like the smell of vanilla. However, over time it does fade to be almost barely noticeable.
Hi, Does this strap fit 1,78mm spring bars? I know some straps from Bonetto will only fit the 1,5mm spring bars.
BR
Yes, it accommodates 1.78mm (1.8mm) spring bars; these are included with the strap at no extra charge.
