‘It feels as good as leather, but waterproof.’ When customers describe rubber straps this way you have a winner. It’s no surprise, given our brief to Bonetto Cinturini for this understated strap with refined sculptural detail.

On first glance, simple lines suggest a plain, functional rubber strap. Only when you examine a ZULUDIVER 317 closely will you fully appreciate the delicate ‘cavatto’ cutaway. In boat-design terms, it’s like comparing Carlo Riva’s timeless Aquarama with the latest Gabrielle Teruzzi concept.

Decades of expertise with high quality rubber straps

For decades, Bonetto Cinturini has specialised in making high quality rubber watch straps. Since the 1980s, they’ve consistently met the functional needs of divers, swimmers, other athletes and discerning leisure wearers. They’re even made in the same factory as many luxury brands’ OEM straps!

For this collaboration, we created another classically unpretentious waterproof range that’s strong, supple, saltwater and UV resistant. Like all our Benetto Cinturini straps, it combines durable NBR (not lint and dust-attracting silicone rubber) with contrasting hardware. The stainless steel tang buckle is ZD-signed to indicate its authenticity. Next to the sandblasted hardware, two colour-keyed box-section keepers echo the 317’s precision-cut strap holes.

The result? Another supremely comfortable rubber watch strap that looks great underwater, on the bridge or out on the town. It was inevitable when Italian flair met our meticulous design brief.

    About HNBR Rubber

    HNBR rubber is designed to withstand harsh environmental conditions like salt-water and UV (ultraviolet) rays therefore ideal for fitting to your diver's watch. The rubber is also very durable, flexible and very comfortable to wear.

    Specifications

    Clasp Material
    The clasp is an essential component of the watch strap as it ensures that the watch stays in place and provides a comfortable fit. We don't use any cheap materials for our clasps and buckles, we use premium stainless steel which is highly durable, extermly strong and corrosion-resistant.
    Stainless Steel
    Clasp Tongue Width

    The tongue width of a buckle on a watch strap refers to the measurement of the narrow part of the buckle that fits through the holes on the watch strap to secure it around your wrist (J).

    4mm
    Clasp Type

    There are several different styles buckles available, the most common type of watch strap buckle is a pin (tang) buckle. It features a traditional tang and pin system, where the tongue of the buckle is inserted through the holes on the strap, and a pin holds it in place.

    Buckle
    Strap Length(s) 134mm / 74mm
    Strap Fastened Max Length

    The maximum fastened length refers to the longest adjustable length of the watch strap. Please note you will need to allow for the watch case if you are determining your wrist size for a watch strap.

    185mm
    Strap Fastened Min Length

    The minimum fastened length refers to the shortest adjustable length of the watch strap. Please note you will need to allow for the watch case if you are determining your wrist size for a watch strap.

    Strap Material

    When selecting a replacement watch strap, here are some factors when considering the material: comfort, style, durability, water resistance, skin sensitivity, suitability for daily use, exercise and adaptability to different weather conditions.
    HNBR Rubber (made in Italy)
    Strap Style Italian Rubber Dive
    Strap Thickness

    The watch strap thickness refers to the measurement of the strap's height or thickness. It is the distance between the top surface (the side facing away from your wrist) and the bottom surface (the side in contact with your wrist) of the strap. The thickness of a watch strap is an important factor to consider as it can affect the overall comfort, aesthetics, and compatibility of the watch with your wrist.

    5.7mm - 3.7mm
    Strap Width Taper

    A watch strap taper refers to the gradual reduction in width from the lug end to the buckle end of the strap, not all watch straps have a taper.

    For example, if a watch strap has a lug width of 20mm and a taper of 2mm, it means that the strap's width gradually reduces by 2mm at the buckle end, resulting in a final width of 18mm at the buckle, so would be refered to as 20mm/18mm.

    22mm/20mm, 24mm/22mm
