Model 285 is defined by its bold wave profile. The sculpted sections are larger and more pronounced than on other Bonetto Cinturini wave straps, giving it a strong, graphic presence that reads unmistakably “dive watch” on the wrist. Round perforations run the length of the strap, adding ventilation without breaking up the overall silhouette. This model favors visual impact over restraint. It’s a good choice when you want a classic dive-strap look with real presence.

Material & feel

Model 285 is made from vulcanized nitrile butadiene rubber (NBR), selected for its durability, flexibility, and resistance to seawater and sunlight. The vulcanization process strengthens the material while maintaining controlled flexibility, allowing the strap to bend naturally without feeling soft or unstable.

Compared to slimmer Bonetto models, Model 285 has a firmer, more structured feel that supports its larger wave design. On the wrist, it feels stable and secure, with enough give to remain comfortable during extended wear. The matte surface resists lint and dust more effectively than many silicone straps and keeps the overall look clean and utilitarian.

Carries a light vanilla scent, typical of Italian-made vulcanized rubber.

I’ve been on the hunt for a good rubber strap for my 2004, 16610, Rolex submariner. I wanted a strap with some texture, as I prefer a more hardy looking rubber strap. What caught my attention with these straps was the great reviews, high quality materials, and similarities to my favorite Gshock straps. After fast and easy shipping from holbens, I received the package and proceeded to open it up. If the looks, initial feel/quality don’t reaffirm your purchase the sweet vanilla smell will! It’s been a week with it on and I can confidently tell you that after trying hundreds of nato straps, zulus, rubber straps, and even the factory bracelet, this is by far my favorite way to wear this watch for now.

This watch strap is beautiful and the color is less garish than on the website in person. It’s well-made and very comfortable. My only comment is that it’s clearly made for a man with a larger wrist than me. I am a woman with a medium sized wrist for a woman, not a man. I have it on the closest hole, which unfortunately means that the end of the strap extends beyond the last holder, so much so that it loops back around to the front, and the end is visible from the front where the watch face is.

It fits the watch and my wrist. Comfortable. Fragrant

I have this Casio from 2010 that I've neglected and kept for sentimental reasons. I got a rubber one because it's the closest material the original one came with. This was a triumphant find because I needed a strap that fits an 8 inch wrist but has a 18mm lug width. I like the texture, softness, flexibility and scent. I just wish it had quick release spring bars. I'm probably not going to wear this watch but I am comforted that the strap seems like it will last for another 15 years.

Excellent rubber strap

Got it for my Sinn 104 and outdoor adventures at Banff Canada. Excellent quality, super comfortable and really looks good on my Sinn 104. Like it so much I still haven't replaced it with my stainless steel bracelet now that I'm back at work.
As others have stated, has a slight vanilla scent that I don't mind. Also on my 7.25 wrist, strap was a bit long for my liking so trimmed it up about half an inch.
My 3rd strap from Holbens, great quality and excellent customer service!

Perfect rubber strap

Great quality, and it really does smell like vanilla. Great way to dress down the Seiko DressKX. This will be my pool companion on spring break.

Excellent quality!

I purchased the BC285 band for my Seiko Sumo. I went with the wider 22mm strap and trimmed the lugs down to 20mm with a Dremel and diamond cutting disc. The thickness of the strap at the lug end is a perfect match for the Sumo’s arms and the added width provides a nice taper from the case arms to the strap. I’ll be picking up another in blue.

The look and scent of summer

Bought this band to switch back and forth between my seamaster and Lorier Neptune. What a great watch band for warmer weather and pool days. The contrast between the orange band and the blue bezel of my Neptune is absolutely perfect. High quality rubber and a charming vanilla scent. You can't go wrong with this band!

Good strap, great service

I bought this as a replacement for my Seiko turtle. This a good band, and has a slight vanilla scent, which I like. The buckle and keeper on this band are okay, but I switched them for the buckle and keeper from my original Seiko band. I will order again from Holbens. Great service, good product.

Good strap

Strap is solid. A little long but it's one size fits all. I've got an average wrist size and there's a whole bunch of leftover strap and I'm on the like second hole. Not ever really a problem though to be honest, looks and wears wonderfully.

Olympic Pro Diver & B-C 285 Strap

Good service, good price, well packed & was delivered Internationally on time.
Fit to the trusty Olympic Pro Diver is good but the bars provided are too small diameter for the holes in the strap - these should be jumbo bars??
That said the strap itself is a very good quality product and comfortable on the wrist.
This should be good for a few more years again...

Perfect for Vostok Amphibia "Zissou" model

I purchased this to get the "Zissou" look on my Vostok Amphibia and I am beyond satisfied. The rubber is so subtle, comfortable and as others have stated, has that great vanilla smell. Having owned a Isofrane as well, this is by far the nicest rubber strap I have ever worn. Excellent customer service as well. Cheers!

Outstanding strap

I have owned several silicone straps, and though they are comfortable, they are not nearly as comfortable as real rubber straps! This Bonetto Cinturini strap is well made, stylish, comfortable, and fashionable. The one thing I really like is it will take a large 2.5 mm spring bar with an .8 mm tip, also sold by Holben's.
It fits my 8" wrist with plenty left over. The keepers are a tight fit so I never have to worry about the tail of the strap coming out.
I also love the vanilla smell of the strap.

Great strap

Fast shipping and the strap fits really well on my Seiko Monster SBDC073. Makes the watch a more comfortable weight and reduces the bling.

Nice!

Very soft and not too stiff like the one that came on my Seiko. Good quality and comfy. Came with heavy duty pins. It's been a week and it still does have a faint aroma of vanilla as the other review mentioned. I like it but If you have a sensitive nose then maybe it's not for you. A+

Great watch band!

This is a great, comfortable band. I have two of them for two different Vostoks and I’ve tried multiple different bands. These are by far the best. As a bonus they are infused with a vanilla scent that seems to last a long time (I’ve had one for a year and still has a strong vanilla scent).
