The Rolex Daytona 116520 is the one a lot of people end up missing after they sell it. On paper it is just the steel Daytona before ceramic, but on the wrist it has its own energy. The bezel is softer, the whole watch feels a touch more “mechanical” than the modern references, and it still wears like a 40mm sports watch should, compact, balanced, never clunky.
It is also one of the easiest Daytonas to change the personality of with a strap. Put it on rubber and the watch stops feeling precious. It turns into something you actually reach for.
Strap size and fit for the Daytona 116520
The Daytona 116520 uses a 40mm case and a 20mm lug width. That 20mm lug width is the key number to keep in mind when you are shopping.
On Helvetus product pages, you do not need to select a watch model option. Our Daytona straps are designed to fit the Daytona case by default, so you simply choose the strap you want from the Daytona range and pick your preferred buckle style. We offer both deployant and pin buckle versions, and you can see the full variety of colors in the Daytona collection here:

If you want to avoid ordering the wrong thing, the simplest rule is this: stick to the Daytona collection, and you are automatically in the correct fit family for the 116520.
The best strap choices for the Rolex Daytona 116520
The 116520 came in a few dial flavors, but most owners live in one of two worlds: crisp white dial or glossy black dial. The nice part is that the strap choices below work with both, just in different moods.
Black is the safe choice, but not the boring one. A black rubber strap gives the 116520 a stealthy, daily-wear edge, especially if you have the black dial. It also makes the steel bezel look even cleaner because everything else gets quieter. This is the strap you throw on when you want the Daytona to feel like a true sports Rolex again, not a “be careful around door frames” watch.

Red is where the fun starts. On the 116520 it feels more playful than aggressive, because the steel bezel keeps the whole watch from going full race-car cliché. If your Daytona is the white dial version, the red strap is a killer contrast, bright without being messy. I also like it for evenings, holidays, and any time you want the watch to look like you are actually enjoying it.
Rolex Daytona Red Rubber Strap
Light Blue is the left-field pick that ends up getting the most compliments. It gives the 116520 a lighter, modern feel, and it is surprisingly flattering against the polished steel. On a white dial Daytona, it leans clean and fresh. On a black dial, it adds a bit of color without turning the watch into a fashion piece. This is the strap I would choose for warm weather, travel, and that “one watch all day” kind of wear where comfort matters as much as looks.

If you are the type who rotates straps, these three cover basically every Daytona mood: stealth, statement, and summer.
Buying the right strap from Helvetus
With the Daytona 116520, fit matters more than people expect. A strap can look great in a product photo and still sit awkwardly on the case if it is not shaped and made for the Daytona profile.
The easiest way to keep it simple is to shop directly from the Daytona collection page, pick the color that matches your dial and lifestyle, then decide whether you want deployant or pin buckle. Everything in that collection is built around the Daytona fit, and there are plenty of other colors there too if you want something more subtle or more wild:

Final thoughts
The 116520 is one of those Daytonas that feels better the more you wear it, and rubber just suits that attitude. Black is the everyday weapon, red is for when you want the watch to punch a little harder, and light blue is the surprisingly addictive option once you try it.
If you are buying from Helvetus, the nice part is knowing the straps are designed for a precise fit on this specific Rolex model, backed by a lifetime warranty, shipped free worldwide with no import costs, and trusted by 30,000+ customers around the world. It keeps the whole experience simple, and it lets you focus on the part that matters: enjoying the Daytona.
