Model 330 combines a fine diamond-pattern texture with a broad, straightforward dive-strap shape. The long row of oval sizing holes and flat profile give it a distinctly old-school look, while the textured surface keeps the large rubber sections from feeling plain. Quick-release spring bars make strap changes fast and tool-free.

Material & feel

This strap flexes easily, drapes naturally, and feels comfortable from the first wear rather than needing time to settle in.

The waffle pattern adds grip and airflow without stiffness. Model 330 feels light and forgiving, even during long days on the wrist.

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

This band checks all the boxes. Great texture, lightweight and flexible.
The close hole placement makes getting the perfect fit a breeze.
Highly recommend.

Very happy so far. I like how thin the band is and how close together the adjustment holes are, allowing you to get a precise fit. Very comfortable right from the start. And, one of the strap keepers has a raised portion that locks into the adjustment holes, keeping it exactly where you want it - No more fighting migrating strap keepers. I just read through the description and info again and agree with everything they are advertising/claiming. Would definitely buy another!

Most comfortable rubber strap I've tried

I've tried numerous rubber and hybrid straps over the years -- most of them much more expensive than this one. This one is really comfortable because the rubber is soft, and the punched holes allow for lots of ventilation -- in addition to a precise fit. Setting it aside for summer.

Another fantastic strap from Holben's

Very soft, flexible material makes for a super comfortable wear. I appreciate the close spacing of adjustments as well. The orange is bright and fun for a diver, although it might be a little too thin for a heavy watch. I paired it with my Islander Northport in blue. Vanilla scent was a little strong at first. My third purchase from Holben's and I am already picking out more straps for other watches!

Bonetto Cinturini 330 Black Rubber Strap

Currently on an Oris; this strap is very well made, EXTREMELY comfortable, and smells great. It also came with Holben's boringly predictable exemplary service. Both strap and Holben's are highly recommended.

This is a great watch strap. Very soft and easy to add to any 20mm watch with quick release. I enjoy the vanilla smell from the strap.

Great feeling on the wrist.

I have worn many different straps and this one is better then most. There are plenty of adjustment holes, to get the right fit for small to large wrists.

Excellent rubber strap

This band was a perfect fit for my Hamilton khaki field Ti 38mm. Best rubber strap I’ve ever worn and I like the slight vanilla scent. Super comfortable with just enough flex that I don’t need to adjust throughout the day. Order fulfillment was seamless with tracking provided.
