In the world of watch accessories, the tropic strap is a timeless and versatile choice for dive watch enthusiasts. Renowned for their durability, comfort, and distinctive design, these straps have become a staple for both vintage and modern timepieces.
In this guide, I’ll explore the essence of tropic straps, uncovering what makes them unique and exploring how to choose the right tropic strap size for your watch.
What is a tropical strap?

The tropic watch strap is a strap that’s typically made from rubber with a very distinct look and history.
The strap has its roots in dive watches. In fact, they’ve been a classic pairing for dive watches since the 1960s, when they were first offered as aftermarket alternatives.
Since then, they’ve gained popularity as the preferred choice for divers and water sports enthusiasts — mostly down to the durability and functionality of the straps. The name pays homage to the strap's ability to withstand tropical climates and harsh underwater conditions, making it the ideal choice for adventure seekers.
The strap's commonly textured surface also makes them comfortable to wear, offering flexibility and breathability during underwater and outdoor pursuits.
Tropic straps are often characterised by their recognisable design. They tend to have a perforated pattern (like a crosshatch) that not only adds a touch of style, but also serves a practical purpose. The perforations also allow for optimal ventilation — another reason they’re an ideal choice for an active wearer.
What material are tropic watch straps made from?
Tropic watch straps are traditionally crafted from rubber, mostly because they’re paired with dive watches. If used in the water, wearers need a comfortable, flexible, and durable strap — and rubber delivers in all of these areas.
The type of rubber used for tropic straps varies. Some are made from natural rubber, while others are made from vulcanised rubber — like the Original TROPIC® Dive Watch Strap. Vulcanised rubber is slightly more durable. It’s a little more on the robust side, being insoluble to certain liquids and bacteria.
Some contemporary tropic straps also feature materials like silicone or synthetic blends. These innovations can enhance the strap's resistance to environmental factors, ensuring that the strap lasts as long as possible.
Are tropic straps durable?

In a word, yes. As mentioned, most tropic straps are made from rubber, which is resistant to water, sunlight, and temperature variations, making it an ideal choice for use in diverse environments.
Rubber also has resistance to various chemicals, including those found in sunscreen, saltwater, and cleaning agents. This resistance ensures that the strap maintains its structural integrity even when exposed to potentially damaging substances.
Although tropic straps are made for durability, the longevity of any watch strap depends on proper care and maintenance. Regular cleaning, avoiding prolonged exposure to harsh chemicals, and storing the strap away from direct sunlight when not in use can further extend its lifespan.
What size are tropic straps?
Tropic strap sizes vary, and the best size depends on the watch you’re pairing it with. You wouldn’t pair a large watch case with a slight and nimble strap, for example. There are also measurements to consider to make sure your tropic strap fits your timepiece, like lug width.
Let’s look at this (and a few other considerations) in more detail to help you find the right size tropic strap.
Lug width
The primary measurement to consider when determining the size of your tropic strap is the lug width of your watch. The lug width refers to the distance between the lugs (the protruding elements on either side of the watch case).
Most watches provide this measurement in millimetres. Common lug widths include 18mm, 20mm, and 22mm, but variations exist to accommodate specific watch models. For example, our Vintage Tropical Style FKM Rubber Watch Strap comes in 20mm and 22mm, so you can choose the size that best suits your watch case.
It's essential to consult your watch's specifications or measure the lug width accurately to ensure a seamless fit. You can also use a lug width tool to measure the distance between lugs to be sure of the sizing.
Strap length

In addition to lug width, you should also consider the overall length of the tropic strap. The strap should be long enough to comfortably wrap around your wrist and secure the watch in place.
If it’s too short, you’ll find it pretty uncomfortable and restrictive, which defeats the point of using a tropic strap in the first place. You want a strap that’s flexible, comfortable, and that enables you to move freely.
Adjustability

Some tropic straps come with a degree of adjustability, allowing you to fine-tune the fit to your liking.
Look for straps with multiple sizing holes (like the ZULUDIVER Tropical Ocean FKM Rubber Watch Strap), or a deployant clasp that enables micro-adjustments. This adds to the versatility of the strap, ensuring a snug fit without compromising comfort.
How to care for your tropic watch strap
Although rubber is durable, it can be susceptible to certain factors that may impact its appearance and functionality over time. Caring for these straps is essential to ensure its longevity, comfort, and overall performance.
Here are some of the ways to properly care for your tropic watch strap.
- Regular cleaning: Aim for a monthly cleaning routine, or more often if needed. Use mild soap or detergent and lukewarm water to clean your rubber strap, avoiding harsh chemicals such as solvents, detergents, or strong cleaning agents. These substances may degrade the rubber material over time.
- Scrub the strap (gently): Use a soft brush (like a toothbrush) to gently scrub the strap. Pay attention to areas with perforations and the spaces between the strap and the case — these are the areas where dirt may accumulate, and so probably require a little brush action. After scrubbing, rinse the strap under running water to remove any soap residue.
- Dry the strap properly before rewearing. To make sure your rubber strap is dry and ready to wear again, pat it with a clean, soft cloth. Avoid wringing or twisting the strap, as excessive force may cause damage. Or, you can leave the watch to air dry — but don’t leave it in direct sunlight, as UV rays may cause discoloration and deterioration of the rubber.
