Model 284 is one of the most substantial dive straps in the Bonetto Cinturini lineup. The thick wave-patterned profile, perforated body, and reinforced keepers reflect the oversized rubber straps historically associated with professional Seiko dive watches, including Bonetto’s Tsunami motif at the tip. Its longer length and heavier construction suit large modern dive cases that can feel undersized on slimmer rubber straps.

Material & feel

Model 284 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 without feeling soft or unstable.

Compared to slimmer Bonetto models, this strap feels noticeably more substantial. The thicker profile adds structure and weight, helping it balance larger cases while remaining comfortable during extended wear. The matte surface resists lint and dust more effectively than many silicone straps and maintains a clean, utilitarian appearance.

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

Fantastic supple rubber strap that matches the style of the Seiko “Save the Ocean” Samurai accentuates the rich color of the dial. Buy with confidence.

Great watch band

This is the second one I’ve had. The first was on my Tissot that worked great until the watch flooded. Now I’m wearing one on my Doxa 300 and it’s just as comfortable as my last one. I dive with it and it hold up well. A little trimming was needed as it was a little too wide but easy to fit.
These bands are very comfortable and look great.

Perfect Match

I had the hardest time finding a blue strap to go with the dark blue dial/bezel of my Orient Ray II. Nothing I could find quite matched or complemented it well until I found the Night Blue color of this strap. It is absolutely perfect. Even the texture of the band matches that of the bezel. It’s very comfortable for me and the optional brushed steel buckle is a great touch. I could not be more pleased.

Orange is the new Black

Very pleased with the look and fit of this watchband on my Phobios Ocean Master.
The orange band and black buckle go perfectly with the black face and orange minute hand.
It also feels more comfortable than the OEM strap. Kudos!

Perfect Strap

I bought two of these straps to go with my Seiko turtles, these straps are fantastic they are super soft and comfortable and even fit a stock Seiko buckle if you want to match the case color. I give these straps 👍👍 and would highly recommend them to anyone

This is such a great strap. I’m using it on both my Seiko Turtle and my King Turtle. Its essentially a match for the 1980’s OEM Seiko strap, but the vulcanized rubber is much more comfortable with more stretch and I love the vanilla scent of thr Italian rubber. The Seiko fat spring bars don’t fit, so I needed to use a thinner spring bar. Fast shipping by Holben’s.

Item was very good quality. Buying and shipping was a smooth process. Item arrived very quickly. I will definitely buy from them in the future.

An accurate physical homage to the genuine Seiko strap, however, far more supple and rubber like. Those who describe it as being like the old early Seiko article, late 70's and early 80's, clearly didn't own one, they were firm even then. Anyhoo, an excellent strap perfectly suited to the watch, a fake 6159-7010, and, most significantly, really easy to wear and super comfy on my 8.25" wrist.

In my humble opinion, Bonetto straps are the best you can get; the rubber feels supple but isn’t flimsy. But more importantly, Holbens is the absolute best place to get them; lightning-fast shipping (within one hour of ordering!) and quick responses to questions. Seriously, it doesn’t get and better than that.

Great Italian Rubber Strap

I've owned a couple of Bonetto Cinturini straps before and they've all been very good quality. The Italian Rubber used in their straps are high quality and have similar FKM rubber strap attributes. They also have the famous nice "vanilla scent" to them. This particular strap model was exactly what I was looking for for my Grand Seiko dive watch. I also really like the khaki green color. Very military-esque in tone. The strap is very comfortable new and I would highly recommend to anyone looking for such a strap.

Best Rubber Dive Strap

Bonetto Cinturin makes the best vulcanized rubber dive straps out of anyone out there. Comfortable, well made, and simply the best. And per usual, shipping from Holbens was quick and painless. I’m done with buying cheaply made watch straps from other shady and dubious dealers. Holbens is the best watch strap dealer in the business.

Better now

I have a couple of 6309-7049 watches that are in truly remarkable condition and as they are appreciating, I don't wear them very much. I recently purchased a new Seiko "Turtle" so that I could wear what has become my favorite cased watch. It is just so comfortable! I also like the manual winding and hacking as well. The one thing that really rubbed me wrong was the strap and buckle. It is silicone and picks up lint. The buckle and keeper, in my opinion, are too much bling for a tool watch. I got this one as it mimics the original strap (6309-704X) and keeper. I had several of the original Seiko buckles so I put one of those on this strap. My "Turtle" is now complete! I really like the strap as it matches the original in looks and function. Also, because it is made of a superior compound, I know that it will last a long time and be durable. The vanilla smell is a nice touch as well...
