Expertly crafted in Italy for more than forty years, vanilla-scented Bonetto Cinturini rubber dive watch straps have long been trusted by renowned watchmakers for their perfect combination of durability and comfort. Made from high-quality vulcanized nitrile butadiene (NBR) rubber, these waterproof, nontoxic and nonallergenic straps are engineered to withstand seawater and UV radiation from sunlight. In addition, thanks to the repellent properties of NBR rubber (unlike silicone), you can say goodbye to lint and dust! With hundreds (and hundreds) of positive reviews, Bonetto Cinturini straps are a great choice for any watch enthusiast.

With its slim profile and slanted end, Model 281 has a sleek, retro design inspired by 1960s dive watch straps. Round and ladder-style perforations provide a comfortable fit and allow air circulation.


  • Premium vulcanized NBR rubber (not silicone).
  • Vulcanization is a curing process using heat and sulfur that promotes strength, suppleness and protection from abrasion.
  • Polished stainless steel buckle with 8mm tang.


  • Available in 18mm, 20mm and 22mm.
  • 18mm piece length 127mm / 78mm excluding buckle; total length 8-1/8" excluding buckle.
  • 20mm and 22mm piece length 136mm / 80mm excluding buckle; total length 8-1/2" excluding buckle.
  • 4mm thick at lug ends; 2mm at opposite ends.
  • 18mm and 22mm are straight; 20mm is notched (see photos).


  • One free pair of strong, seamless double-flange stainless steel spring bars (Model 281 accommodates a maximum bar thickness of 1.5mm).

Q: Do you sell watch bands for women?
A: We do! Many of our short-length straps are the perfect size for women.

Q: Can you suggest a strap that looks amazing with my watch?
A: Unfortunately, because the range is so vast (and personal taste is subjective), we cannot advise regarding aesthetic suitability for specific models and styles of watches.

Q: I have an Apple watch. Will any of your straps work for me?
A: Sure! Our handy Apple watch band adapters accommodate most 22mm straps.

Q: Are spring bars available?
A: Yes, for each strap that is not already integrated with quick-release spring bars, we include one free pair of strong, seamless double-flange stainless steel bars.

Q: What strap size do I need?
A: To determine your size, use a metric ruler to measure the internal distance (in millimeters) between the lugs of your watch.

Q: My Bonetto Cinturini deployant strap is too long. Can you help?
A: Of course! See our Bonetto Cinturini sizing guide for cutting instructions.

Q: Do you offer international shipping?
A: Yes! Visit our Shipping & Returns page for more information.

Q: May I return my purchase?
A: Holben's Fine Watch Bands accepts returns of unworn, undamaged merchandise for refund or exchange within thirty days of purchase. Learn more on our Shipping & Returns page.

Need help with sizing?
  • Inspect the underside of your current watch strap for width indicators.
  • Measure the space between your watch lugs (in millimeters) using a metric ruler.
  • Research the specifications of your watch model on the manufacturer's website.
