Bonetto Cinturini 328 Rubber Military Watch Strap - Orange
Made in Italy from vulcanized NBR rubber. Waterproof, UV-resistant, and nonallergenic.
Model 328 translates the classic military pass-through strap into rubber, with a broad one-piece layout, fine ribbed texture, and simple hardware. The flat profile and uninterrupted surface give it a straightforward utilitarian look that suits tool and dive watches especially well. The removable secondary layer allows the strap to be converted from a traditional double-pass layout to a lower-profile single-pass configuration.
Material & feel
Model 328 is made from vulcanized nitrile butadiene rubber (NBR), a material chosen for its durability, flexibility, and resistance to seawater and sunlight. The vulcanization process strengthens the rubber while preserving a controlled, supple feel.
The strap is constructed from two thin layers of rubber, each about 1.5mm thick, creating a structure that bends easily around the wrist. The finely ribbed texture provides subtle grip and visual definition while remaining understated compared to heavily patterned rubber straps. Sandblasted stainless steel hardware reinforces the utilitarian character and keeps reflections muted.

Fit guidance
Bonetto Cinturini military rubber straps use adjustable keepers to set the fit on the wrist. Excess strap length is folded back and secured rather than trimmed. The secondary pass-through layer can be removed to convert the strap to a single-pass configuration with less height under the watch.

I picked up the Bonetto Cinturini 328 Rubber in Blue 294 for my Pelagos FXD MN. It is literally the perfect match to the blue of the FXD MN. I love the versatility of being able to use it as a single or double pass NATO. The rubber is soft, and pliable but a good strength to it. Smells of vanilla. It feels quality. Mike with Holben’s was fabulous, shipping it out PDQ. Now trying to not order an orange and gray one!
This thin, light weight, flexible band with a nice amount of stretch is my go to pick for multiple watches.
I removed the extra pass of rubber and the extra metal keepers to create the most comfortable single pass strap I own.
This strap is very long apparently to allow wearing over a wet suit, but it cuts down very easily with a razor blade, knife , or sharp scissors to allow a custom length of tail after the keeper.
A plastic water bottle lid or coin made a nice guide for cutting the end to perfect length.
Ordering more for sure!
This was a great purchase. Was looking for an alternative to my factory Tudor rubber FXD rubber band. This easily converted to a single pass band by removing two spring pins and the secondary strap. Not as thick as the factory strap but cleaner and smoother. Good value.
I Just found my Favorite NATO and its Rubber from Bonetto Cinturin! Fit is perfect and its very comfortable. Perfect all around strap.
The best rubber strap I have. It's comfortable and strong for being thin. Will buy another one. Holben's is where it's at!
This is the perfect NATO for my use. I wanted a strap that was lite, that was rubber, that smelled great, and looked good. Plus you easily make it a single pass ZULU. I wish they had it in Orange.
One of the best NATO straps I've ever experienced. Strapped my Sinn EZM 3 on and the perfect pair for a diver or for daily wear. Easy on the wrist, greats looks, durable and easy to clean!
I can't say enough good things about this rubber NATO strap! First, it's very supple and fits my wrist perfectly. I was able to trim the end off so that I don't have to double the strap over into the second metal keeper. I used an X-Acto knife and a coin to keep the end of the band rounded. Another thing I really like about this NATO strap is that it's not so thick that my watch sits too high on my wrist. It has a very low profile since it's just 1.5mm thick. I wear it on a Sinn 356 acrylic Flieger and I like the look of this combination (check out the attached photo). Finally, the strap has a slight hint of vanilla which is actually kind of pleasant. The scent is less pronounced now after a few days of wearing it, though. If you're into NATO straps, you should definitely look into owning one from Bonetto Cinturini.
Beauty. Such a lovely italian rubber strap. I have the 20mm version in navy on my newly acquired seiko sbdc053. 7 inch wrist. Fits perfect.
My new favorite Nato. Not sure why it's vanilla scented, but that doesn't detract from the quality of the strap. However you may develop a craving for cookies or a brownie. I've got it on a Seamaster Professional Apnea and it looks great. Strong enough to stand up to the weight of the watch without being bulky itself. I wish they carried the other colors in this series,

Best band ever
I picked up yet another Bonetto Cinturini 328 NATO strap, this time in steel blue. Very unique color which pairs well with black or silver dialed watches. I get a lot of compliments on this one. Super comfortable for year-round wear.
This is the second Bonetto Cinturini 328 in light gray I have purchased from Holben's. Not only is it the best rubber NATO strap out there, but I think it is the best NATO in any material, period. The light grey goes with pretty much any dial or case color. Great style and comfort. You can't go wrong with this strap.
I picked up the Bonetto Cinturini 328 Light Grey NBR Rubber NATO, the latest of many Bonetto Cinturini purchases. Not only is this the finest Rubber NATO, but I think it is the best NATO, period. Super comfortable and stylish. This shade of grey is fantastic. Looks very much like Admiralty Grey on my CWC watch Great price and value.
I picked up the Bonetto Cinturini 328 Steel Blue NBR Rubber NATO, the latest of many Bonetto Cinturini purchases. Not only is this the finest Rubber NATO, but I think it is the best NATO, period. Super comfortable and stylish. This shade of blue is fantastic. Great price and value.
I was looking for a rubber nato for when I swim and bike and this fits the bill. The rubber is good quality with a strong buckle and have no concerns of losing it when I am doing phycical activity.
Being a big fan of Bonetto Cinturini NATO straps, I decided to pick up the Azure Blue. Lovely color and super comfortable. Looks fantastic with any silver, white or black dialed dive watches. Outstanding quality and value!
These are the best aftermarket straps I've found. They are durable and wear very comfortable, they look and feel premium for a budget price.
I purchased the Bonetto Cinturini NATO in yellow for my Mk II Fulcrum 39. This is a fantastic summer strap... comfortable, handsome and naturally water resistant. Looks great with the black dial and bezel insert. Great price and quality. Will definitely be purchasing this strap in other colorways.
I've purchased many NATO straps, but the rubber one offered by Bonetto Cinturini in EMERALD GREEN is absolutely the best there is. Looks and smells great and super comfortable. Remarkable price for this quality strap as well. It is a winner!
This has become my favorite strap for dive watches. It just works, its laid back but still looks put together. I find it comfortable even in hot weather. It's easy to install and adjust. It is of course waterproof. It smells good too, but you may not want to buy this if scents bother you. I think this price is good for the quality of the strap.
