ZULUDIVER 285 Italian Rubber Diver's Watch Strap - Black
Pay Securely
Practical refinements, different strap widths and separate floating keepers are among the differences between the ZULUDIVER 285 and our 284 strap. The reassuring Bonetto Cinturini quality, Italian style and sheer wearability are the same.
As for its stablemates, the ZULUDIVER 285 rubber strap is manufactured to Bonetto Cinturini’s high standards. It's the same factory where the strap specialist has made high quality watchbands for over 30 years – including OEM straps for luxury Swiss watch brands!
Performance and quintessential Italian style
Based on our specification, Bonetto Cinturini bring their reputation for quality, performance and quintessential Italian style to a two-piece rubber strap that’s ideal for diving and many other activities.
Strength, suppleness and simplicity meet our brief here: the 20 mm and 22 mm widths reflect contemporary lug widths; precision strap holes are flanked by additional perforations; and we’ve included more perforations on the strap’s buckle-piece. Added to two floating keepers and ‘accordion’ expansion, we're sure you’ll enjoy a comfortable wear. Talking about hardware, you can be sure the ZULUDIVER-signed stainless steel hardware is up to the challenge of your active lifestyle.
Waterproof, salt water and UVA resistant
We understand that your watch strap is a crucial accessory, wherever you adventure. As ever, these straps are made of high-quality non-toxic, non-allergenic rubber. It’s waterproof, salt water and ultraviolet-A (UVA) resistant, so perfect for long days in the sun and water. And while the aesthetics attract admiring looks, the vulcanised rubber (not silicone) means less likelihood of attracting unsightly dust and lint.
This is a high performance, durable rubber watch strap made to work and play hard. From tang buckle to slightly squared-off strap tip, it’s a worthy companion for affordable or luxury dive watches alike.
Buy and wear one with confidence
Of course, the combination of a ZULUDIVER 12-month guarantee and Bonetto Cinturini quality means you’ll buy and wear yours with confidence. Now choose the colour…
