The Rolex Datejust 36 ref. 126200 is the stealth Datejust. Smooth bezel, clean lines, and that “I wear this because I like it” energy. It doesn’t have the sparkle of a fluted bezel or the extra flash of two-tone, which is exactly why it works so well as a daily. You can dress it up, beat it up a little, and it still looks right.
Straps suit this reference more than most people expect. The case is tidy, the proportions are classic, and because it isn’t visually loud, you can play with color without the watch looking confused.
Strap sizing for the Datejust 36 (126200): the only part you can’t wing
This one is simple, but it’s worth saying clearly.
Your watch is 36mm, and the lug width is 20mm. If you’ve ever tried a strap that’s “almost” the right size, you know it never looks almost-correct. It looks wrong. On a Datejust, especially a clean-bezel one like the 126200, those little fit details stand out more than they would on a chunky sports watch.
When you’re ordering from Helvetus, there’s good news: if you choose straps from the Datejust 36mm collection, you don’t need to select any model or fit option for the 126200. There isn’t one. Everything in that collection is already made to fit the Datejust 36 case properly, so you just pick the style you want and decide between deployant or pin buckle.
Full selection is here (colors, buckle versions, everything):

The strap choices that make the 126200 shine
The 126200 is versatile by design, so the strap you choose should match how you actually wear it. Not how you think you wear it.
Navy Blue deployant strap
Navy Blue Rolex Datejust 36mm Rubber Strap
Navy is one of the best “smart casual” colors in the watch world, and it’s especially flattering on the steel Datejust 36. It gives the watch depth without going full black-tie. If you’ve got a blue, silver, or white dial, navy makes the whole setup look considered, like it belongs there.
What I like most is how navy changes the vibe without changing the watch. It still feels like a Datejust, just a little sharper and more modern. Great for everyday wear when you want something different from black but still want it to work with almost anything.
Black/Green LuxLine® deployant strap
Black/Green LuxLine Rolex Datejust 36mm Rubber Strap
This is for when you want the Datejust to feel less “classic dress watch” and more “daily favorite.” The black base keeps it grounded, while the green LuxLine® detail adds a sporty edge that actually works with the 126200’s clean silhouette.
Green also plays nicely with a surprising number of dials. Black dial? Easy. Silver dial? Looks crisp. Even the more playful Datejust colors pair well because the strap isn’t screaming neon, it’s giving a controlled pop of color. If you like the idea of a Datejust that feels a bit more contemporary without losing its identity, this one hits that balance.
Black deployant strap
Black Rolex Datejust 36mm Rubber Strap
Black is the no-drama option, and I mean that as a compliment. On the 126200, black makes the watch feel instantly more formal and a bit more serious. It’s also the easiest strap to wear if the Datejust is your only watch and you need it to cover everything from meetings to weekends without thinking.
Black works with every dial, obviously, but I especially like it with brighter dials because it frames the watch and makes it look cleaner. On a 36mm case, black also adds a bit of visual weight, which can make the watch feel slightly more “present” on the wrist without actually changing the size.

The stuff you appreciate after the honeymoon phase
The first day is about looks. The next weeks are about whether the strap actually fits properly and feels like it belongs on the watch. That’s why “made for this model” matters with a Datejust, where everything is clean and visible.
