Next-level straps - The ZULUDIVER TSUNAMI Rubber Deployant Watch Strap
When you set out to deliver a next-level quality strap, it starts with a discussion. In essence, the ZD Team thought about what they would love to see in a perfect rubber strap. It’s a lofty starting position but we all know that anything is possible - so why not aim high?
Everyone in the team had a small technical detail they wanted to see and through the collaborative process that is ZULUDIVER’s design we tried to accommodate all ideas which would enhance the final product.
The result is called Tsunami.
This is a premium deployant clasp which has been subjected to the highest attention to detail. Starting with the diver's buckle which is a classic fold-over design with a flip-lock style safety catch. Two push buttons control the opening process for enhanced security. All elements of the buckle are constructed of 316-grade stainless steel.
The two rubber elements of the strap, which sport a unique ZULUDIVER moulded design, have six micro-adjustment holes on the clasp for extra fine-tuning to perfectly fit your wrist. The minimum overall length is 120mm (5.5 inches), and the maximum length is 200mm (8 inches). Sizing the strap is mainly achieved by cutting the rubber strap across the clearly embossed lines to get the right length on either side of the buckle for your wrist.
The case ends of the strap have quick-release spring bars and we are also offering wider Seiko-type spring bars with the correct tips.
For the primary rubber material, we selected HNBR rubber, or to use its full name - Hydrogenated Acrylonitrile Butadiene Rubber. This exceptional material is used in the automotive industry for engine belts as it has excellent mechanical properties as well as strong resistance to oil, gas, hot water and abrasion. Additionally, it is guaranteed to withstand temperatures up to 140 degrees Celsius.
IMPORTANT INFORMATION: How to properly size the Tsunami strap
To fit your wrist, the rubber watch strap can be sized by cutting it with a sharp blade. On the underside of the strap, we have incorporated clear-cut lines to assist in accurate cutting. Before you can cut the sections, you must first remove the buckle using a spring bar tool.
Caution: We always advise testing the fit of the watch strap on your wrist by removing one section at a time from the watch's opposing sides. The metal pin that is installed in each section must be removed in order to insert the spring bar. Remember you can always cut another segment off; you can’t add one back!
Please be aware that the spring bars used to fit the buckle have tips of slightly different sizes; the micro adjustment spring bar (12HR position) has a longer tip. As a result, please make sure to reattach the spring bar to the proper side of the buckle.
The micro-adjustment positions on the buckle will help you get the perfect fit to your wrist. We have posted a demonstration video on the ZD and WatchGecko websites to help you achieve the perfect tailored strap.
