ZULUDIVER Mayday "Regatta" – Lorica Lined Sailcloth Watch Strap

Built for the toughest adventures, the Mayday Regatta Sailcloth strap is where rugged durability meets all-day comfort. Designed in a classic remborde two-piece style and engineered with our innovative PVC sailcloth rubber, this strap doesn’t just shrug off water, it disperses it.

Engineered and Tested for Endurance

We didn’t just design this watch strap, we pushed it to its limits. To make sure it could stand up to real-world adventure, the Mayday Regatta went through six brutal durability tests:

  1. Dry Rub Test (150 cycles, 1kg pressure): No discolouration, no wear, just flawless performance.
  2. Wet Rub Test (150 cycles, 1kg pressure): Even under soaking conditions, the surface held strong without a mark.
  3. Flex Test (2,000 cycles): Simulating daily bending through the buckle, no cracks, no scratches.
  4. Flex & Load Test (1,000 cycles, 0.5kg weight): With added pressure, the strap still bent and bounced back without damage.
  5. Pull Test (15kg for 1 min): The spring bar area stayed rock-solid under serious strain.
  6. Twist Test (3,000 twists, 5kg pressure): Withstood extreme twisting forces, passed without defects.

Layered for Performance

Top layer of our sailcloth is built with a triple-layer construction:

  • Base layer: Black woven cotton fabric, giving tear-resistant strength.
  • Middle layer: Grey neoprene foam, adding flexible comfort that adapts to temperature and time.
  • Top layer: Embossed PVC sailcloth rubber, rugged, abrasion-resistant, and uniquely textured for a sleek yet tough finish.

Comfort Meets Adventure

  • Lorica lining: A vegan, eco-friendly alternative to leather that’s lightweight, breathable, and hypoallergenic. Comfortable against your skin, even in extreme conditions.
  • Quick-release spring bars: Snap your strap on and off in seconds.
  • Solid stainless steel buckle: Brushed finish for understated strength.

Why Choose the Mayday?

Because this strap isn’t just for show, it’s tested, proven, and adventure-ready. From cockpit to canyon, campsite to city streets, the Mayday Regatta is a strap that keeps up with you, wherever you take it.

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).

2mm
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.

Pin buckle
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.

170mm
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.

135mm
Strap Length

The length of a watch strap is an important consideration to ensure that it fits comfortably around your wrist. For our range typically the long strap length is around 120-130mm, and the short strap length is around 70-80mm and designed to fit average wrist sizes.

120 / 75mm
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.
Sailcloth
Strap Style Sailcloth
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.

4.3mm - 3.2mm
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.
