Best Rubber Straps for Seiko Willard SPB151

As summer sunshine beckons and warm breezes invite adventure, it’s the perfect moment to refresh your Seiko Willard with a strap that can keep pace. Renowned for its rugged, tool‑watch DNA and unmistakable cushion case, the SPB151—affectionately known as the "Willard" after its vintage inspiration worn by Captain Willard in Apocalypse Now—deserves a strap collection that’s as resilient as your holiday spirit.

Whether you're diving into crystal-clear waters, hiking coastal trails, or simply soaking in golden sunsets, a well-chosen strap can elevate both comfort and character. And because the Willard is quite the “strap monster”—well-proportioned and always ready to take on a fresh new look—there’s no better moment to gear up your strap collection for summer.

That’s where we come in. We’ve meticulously curated a selection of top-tier straps across nylon, leather, and rubber, each one chosen to complement the unique personality of Seiko watches like the Willard. But today, we're focusing on summer's standout performer: rubber. Durable, low-maintenance, and ready for anything, here are our best rubber straps for the Seiko Willard.

The Sedona CTS offers a sleek, contemporary approach to summer watch wear, perfectly suited to the rugged charm of the Seiko Willard. Its cut-to-size design means you can achieve a truly personalised fit, eliminating excess material for a cleaner profile that wears comfortably all day—whether you're travelling, swimming, or just out in the heat. The deployant clasp not only adds a touch of refinement, but also ensures a secure, even pressure across the wrist, ideal for longer wear in humid conditions. Paired with the Willard, the Sedona CTS feels both robust and elevated—a modern strap for a timeless dive watch.

The Seacroft Waffle Strap brings together retro styling and serious summer performance in a way that feels tailor-made for the Willard. Its textured surface draws inspiration from vintage dive straps of the 1960s and '70s, nodding to the Willard’s own historic roots. But beyond the looks, the waffle pattern serves a practical purpose—offering airflow across the wrist and helping moisture evaporate more quickly. The supple, flexible rubber wears comfortably straight out of the box, and its classic dive strap profile accentuates the Willard’s bold case shape without overwhelming it. If you’re looking for a strap that honours heritage while staying cool and functional in summer, this is a go-to choice.

Technically a hybrid strap, the Atlas brings the best of both worlds with a rugged sailcloth upper and a rubber lining for sweat and water resistance. It’s a clever solution for summer wear, especially when you want the aesthetic of a fabric strap without the drawbacks in heat and humidity. On the Willard, it adds a military or field-watch vibe, further enhancing the tool-like versatility that makes the SPB151 such a cult favourite. Whether you're heading off-road or just appreciate a tactical edge to your strap rotation, the Atlas is an ideal match—practical, durable, and well-balanced on the wrist.

If you’re after something a little different for your Willard, the Vintage Style Perforated strap adds just the right amount of retro flair. Inspired by motorsport straps from decades past, its perforations aren’t just for show—they boost breathability, making it one of the most comfortable options for hot and humid conditions. While it leans more toward racing than diving, that contrast plays nicely with the Willard’s design, giving the watch a more playful and unexpected summer personality. It’s a lightweight option that feels casual and fun, without compromising the watch’s utilitarian spirit.

Minimalist in design but big on comfort, the 285 Italian Rubber strap is built for serious summer wear. Made in Italy from high-quality rubber, it offers a soft, pliable feel that moulds to the wrist and resists the sticky, sweaty feeling that some straps can cause in warmer weather. It keeps things simple, allowing the Willard’s character to shine while adding just the right level of practical, low-maintenance comfort. Whether you're in the water, in transit, or on your feet all day, this strap delivers all-round performance. If you like your gear to be understated but effective, this one’s a must-have in your summer rotation.

With the right rubber strap, the Seiko Willard transforms from an iconic diver into the ultimate summer companion. Whether you lean vintage, modern, or somewhere in between, there’s a strap here to match your plans—and your personality.
