The Rolex Datejust 36 ref. 116234 is peak “proper Datejust.” It’s the reference a lot of collectors quietly miss once they’ve tried newer models, because it just wears so naturally. The 36mm case sits flat, looks balanced from every angle, and has that classic Datejust vibe that doesn’t need any explaining.
It’s also one of those watches that feels different depending on what you put it on. Bracelet makes it traditional. Strap can make it look cleaner, sportier, even a bit more modern, without changing what the watch is at its core.
Strap size and fit for the Datejust 36 (116234)
Before we get to colors, get the sizing right. That’s the whole game.
The Datejust 36 is 36mm, and it uses a 20mm lug width. That 20mm measurement is the one you need to match. If you go narrower, you’ll see gaps. If you go wider, it won’t sit correctly and you’ll end up fighting the strap. Neither is worth it.
Ordering from Helvetus is straightforward: if you’re shopping inside the Datejust 36mm strap collection, you don’t need to choose any fit option for the 116234. There isn’t one. All straps in that collection are already made to fit the Datejust 36 case properly, so youOA3f: pick the color you like and decide whether you want deployant or pin buckle.

The strap colors that suit the 116234 best
The 116234 tends to show up with dials that range from black to silver to blue, sometimes with a bit of texture. The nice thing is: the watch is classic enough that you can play with strap colors without it looking like a fashion experiment.
Navy Blue deployant strap
Navy Blue Rolex Datejust 36mm Rubber Strap
Navy is an underrated “upgrade” color. It feels more interesting than black, but it’s still conservative enough that you can wear it every day without thinking. On a 36mm Datejust, navy keeps things elegant and slightly modern at the same time.
If your dial is blue, navy obviously looks seamless. But I also like navy with silver dials because it adds depth and makes the whole watch look more intentional. It’s the strap I’d choose if you want something different but you still want it to look like you have taste, not a drawer full of random straps.
Black deployant strap
Black Rolex Datejust 36mm Rubber Strap
Black is the easy answer, and sometimes the easy answer is correct. On the 116234, black sharpens everything up and makes the watch feel more formal, especially if you’re wearing it as a daily office watch.
What black does particularly well on this reference is make the Datejust feel a touch more “evening-ready.” It’s cleaner, a bit more serious, and it works with every dial color without ever looking like a mismatch. If you’re only buying one strap, black is still the safe bet.
Black/Blue LuxLine® deployant strap
Black/Blue LuxLine Rolex Datejust 36mm Rubber Strap
This one is for people who want the Datejust to feel more casual and current, without turning it into something it isn’t. The black base keeps it classic, while the blue LuxLine® detail adds contrast and a bit of energy.
On a 36mm case, that stripe detail actually helps the watch feel a little more “sporty” in a clean way, especially with darker dials. It’s a great option if you wear your Datejust with jeans and sneakers as often as you wear it with a shirt. The watch still looks refined, it just looks less traditional.
