Bonetto Cinturini 281 Rubber Watch Strap - Black
Made in Italy from vulcanized NBR rubber. Waterproof, UV-resistant, and nonallergenic.
Model 281 is a slim, vintage-leaning rubber strap inspired by dive watch designs of the 1960s. The profile is tapered and lightly contoured, with a slanted tail that gives it a more refined, period-correct look than most modern rubber straps. A mix of round and ladder-style perforations provides ventilation and flexible adjustment while reinforcing the retro character. Compared to heavier dive rubbers, Model 281 wears lighter and more streamlined, making it a strong match for vintage divers and slimmer tool watches.
Material & feel
Model 281 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 keeping it supple, allowing the strap to bend easily without feeling soft or unstable.
The surface has a matte finish that resists lint and dust more effectively than many silicone straps. On the wrist, the strap feels flexible and controlled, with enough structure to stay secure while remaining comfortable for extended wear.
Carries a light vanilla scent, typical of Italian-made vulcanized rubber.

This strap has an interesting look and is more comfortable than my Isofrane and Tropic straps.
Close pin holes for great adjustability, very soft and flexible.
Really love this thing, except for two small things: It uses smaller spring bars and actually had one side pop off while doing pushing my kid on his sled, kind of weird, and then for some reason is doesn’t lay quite as flat as I’d like at the buckle. Using on a Mido Ocean Star, and it’s a pretty nice match. I got it as a cheaper alternative to an Isofrane, but still want to try the Isofrane to compare. For the price, it’s perfect.
Thanks Holben’s for another quality item! Love the Bonetto Cinturini rubber straps. An immediate upgrade for feel and style, paired with the Citizen BM8180-03E. Very comfortable.
The Cinturini 281 is a perfect replacement for my Vintage Zodiac Seawolf !
The size is just right and the quality is amazing for the price.
Arrived quickly and packaged extremely well. While most companies, IMO, ship whenever, Holbens gets your item shipped QUICK! It’s always a pleasure to buy from Holbens.
I own so many of straps from Bonetto Cinturin. They feel great on the wrist, have the best materials, and they look as great as they feel. In particular, this strap. It has classic good looks and allows your wrist to get ventilation and breathe. I love this shop! And I love this watch strap company! It’s always a must buy!!
The best that you can buy as well as good value … very comfortable..::
I purchased the Bonetto Cinturini 281 in green for my Seiko diver. Beautiful shade of green in a great retro look. Super comfortable and priced great. Super value for what you get. More colors in this model, please!
Yay!! These are my all time favorite Bonetto Cinturini straps (thin yet strong, gorgeous aesthetic with the super cool circular holes and that buckle😃) and guess what - they finally come with TWO (yes, TWO) keepers!!!! No more “keeper” procurement from other straps needed, because……these great straps now have their very own TWO keepers!!!!! YAY!!!!👏👏👏👏👏 Well, there is one tiny little bit of negativity I will share though, I do wish the folks at BC (Bonetto Cinturini) would lighten up a tad on the over whelming use of vanilla extract scent! Hey, I love vanilla & its delicious scent, but maybe not such a hefty dose on my wrist (please🙏)! Hmmm, Bonetto “Scent”urini 😉
B.C. Are the best watch straps I have ever owned. The feel says top notch all the way. Just the look of this strap says class. I invite you to try a B.C. strap, you will know that you have made a great choice. GO FOR IT!
Fast delivery and cheaper than buying here in Europe plus import tax.
Thankyou
Shockingly fast shipping - received the band in 2 days, and it's a 100% genuine Italian vanilla scented Bonetto Cinturini. Outstanding service gents.
Quality strap that should last for years. Fast shipping from this great seller.
Good strap recommended by TGV. Looks great. Thanks!
Seriously fast shipping and a great strap to boot! Well done..
Great stuff as usual. Thanks guys!
The Best super happy thanks best seller ever
Ideal strap for a retro 'Skin Diver' watch. Top quality and just quirky enough to pull off the look.
Legit Italian vanilla scent dive strap. Feels amazing on this Jade Monster Seiko. Be warned, super fat spring bars will NOT work. The spring bars included are a bit flimsy but I bought a strap, not spring bars. Had my own 20mm bars and went on with no issues. Holben's are the guys with Bonetto Cinturini on lock on Amazon, and they are good guys to deal with. I could go slightly cheaper with rubber straps, velour or perlons but why?
Cool retro dive band goes perfectly with my retro Orient Sea King dive watch.
Very beautiful strap that is well made and extremely comfortable. The strap is made of real vulcanized rubber (not silicone) so it won't attract lint and remains waterproof and more resistant to seawater.
The very best rubber strap I own. Superior craftsmanship, incredibly supple, and a pleasure to wear!
There is a limited selection of long (over 200mm/8”) rubber watch straps, especially in the 18mm lug width I need for my classic Vostok Komandirskie and Amphibia watches (depends on the specific case model). This one doesn't taper, so it looks about as wide as you can get with the 18mm width. I like the 285 model too, but it tapers to the buckle a bit. I think this band looks inside-out with mold marks around the holes and at the edges, so I turned the buckle around and now the cool ribs/cuts are on the outside so you can see them. I have tried silicon and PU (polyurethane) bands but they are not as soft and flexible as these NBR bands. I even like the vanilla smell!
TOO THIN
We appreciate your feedback. The 281 measures about 4.0mm at the lug end tapering to around 2.0mm, which is slimmer than some Bonetto Cinturini models.
Came quickly and as expected. Cinturini products are always first rate.
The most comfortable rubber strap you will ever wear.
