The Datejust 36 ref. 116231 is the one that made rose gold normal. Before it, two-tone meant yellow gold, and yellow gold meant your father's watch. Everose changed that, and the 116231 is where it landed on the reference everybody actually wears: a 36mm Oyster case in steel, with the bezel, the crown and the centre links in 18k Everose.
It is also, quietly, one of the best strap watches Rolex has ever made. The warm metal does something on rubber that a plain steel Datejust can't do. It stops looking like a formal watch you keep for occasions and starts looking like the watch you wear to everything.
Strap size and fit for the Datejust 36 (116231)
Get this part right and the rest is just taste.
The 116231 has a 36mm case and a 20mm lug width. Twenty millimetres is the number that has to match. Go to 19mm and you'll see daylight either side of the strap. Go to 21mm and you'll be forcing it in, which is a bad idea on lugs that are fully polished.
On Helvetus product pages there is no size option to select for this reference. Everything inside the Datejust 36 collection is already cut for this case:

The only real decision is buckle style. The deployant version is made to work with your original Rolex deployant clasp, so the watch keeps the closure it came with. The pin buckle version comes with a steel buckle included and is the simpler, more casual option.
One detail specific to this reference: if your 116231 came on the Jubilee, that bracelet uses the hidden Crownclasp rather than the standard folding clasp. If you want to reuse your original clasp, message support with your bracelet type before ordering, or just take the pin buckle version and skip the question entirely. If you're on the Oyster bracelet with the Oysterclasp, the deployant version is the natural choice.
What the 116231 actually is
Rolex introduced Everose — its own pink gold alloy, mixed with a touch of platinum so the colour never fades out over the years — and then put it on the Datejust 36 in this six-digit reference. It ran for well over a decade before Rolex retired it in 2018 and replaced it with the 126231.
Inside is the calibre 3135, the movement that carried Rolex through decades and still has a reputation for being close to unkillable. Sapphire crystal, 100 m water resistance, fluted Everose bezel, Oyster or Jubilee bracelet.
What separates it from the five-digit Datejusts people compare it to is construction. The 116231 has fully solid centre links and thicker, polished lugs, so it wears with real weight for a 36mm watch. Dials ran the full range: white, black, silver, pink, mother-of-pearl, chocolate, Roman numerals, factory diamonds. Today they trade roughly in the $10,000–$14,000 band depending on dial and bracelet, which makes this one of the more sensible ways into a solid-construction gold Rolex.
Why owners put this one on rubber
Two reasons, and neither is about the watch looking "sportier".
The gold wears faster than the steel. On an Everose Rolesor bracelet, the polished gold centre links are the softest, most exposed surface on the whole watch. They pick up hairlines from desks, car doors and door handles far quicker than the brushed steel around them, and once that crispness is gone it doesn't come back. The days the watch is going to get knocked around are exactly the days it doesn't need to be on the bracelet.
The identity survives the swap. This is the part people get wrong before they try it. All the gold that makes a 116231 look like a 116231 lives on the bezel and the crown, not the bracelet. Take the bracelet off and it still reads as an Everose two-tone from across a table — you've just removed the metal volume and left the gold detailing. It's the same reason two-tone looks better on rubber than most people expect.
Third, smaller reason: at 36mm on a solid-link bracelet, this watch is heavier than it looks. On rubber it disappears on the wrist.
Four strap colours that work on the 116231
1. Brown — the one I'd order first
Everose is a warm metal, and warm metals want warm straps. Brown is the most natural pairing this reference has, and it's the obvious answer if you have one of the chocolate or brown-toned dials, where the strap becomes a straight continuation of the dial colour.
It also solves the "two-tone looks dated" problem in one move. Brown rubber on Everose reads current, not nineties.

2. Black — the one most people actually buy
Black is the safe answer and it's safe for a reason. Against a black strap, the Everose gets more obvious, not less. The contrast pushes the pink of the bezel and crown forward, and the whole watch reads sharper.
Best on black, black MOP and Roman-dial 116231s, and it's the version you want if this is the watch you wear with a suit and then keep on for dinner.

3. Pink — the dial-match play
Rolex made a lot of pink and rose-toned dials for this reference specifically because Everose invites it. If you own one of those, a pink strap turns the watch into a single tonal object — dial, bezel, crown and strap all in the same family. It's the most "designed" the 116231 ever looks, and it's a combination you cannot buy from Rolex at any price.
Not a subtle choice. That's the point.

4. Bordeaux — the grown-up version of the same idea
If pink is too much but you still want the warm side of the palette, bordeaux is the answer. Deep wine red sits underneath Everose beautifully: it's rich enough to hold its own against the gold, dark enough to stay serious, and it flatters black, silver and mother-of-pearl dials in winter the way brown does in summer.
It's the pick people don't know exists until they see it on the wrist.

If none of those four is your dial, the full Datejust 36 range also runs beige, white, navy, grey, green and more, in both buckle versions.
Make sure you're on the right size first
The Datejust family is easy to mix up, so quickly:
- 36mm, ref. 116231 — you're in the right place, 20mm, no size selection needed.
- 41mm Everose (126331) — different case, different width. Start at the Datejust 41 collection instead.
- Same generation, different metal — the 116234 (white gold bezel) and the 116200 (all steel) share the same 36mm case and the same 20mm fit.
Quick answers
What lug width is the Rolex Datejust 36 116231? 20mm. The case is 36mm and the gap between the lugs is 20mm.
Do I need to choose a size when ordering? No. Straps in the Datejust 36 collection are made for this case, so there is no width to select.
Will a strap work with my original clasp? The deployant version is built around the original Rolex deployant clasp. If your 116231 is on the Jubilee with the concealed Crownclasp, check with support first or choose the pin buckle version, which includes its own buckle.
Is the 116231 the same fit as the 126231? Yes — both are 36mm with a 20mm lug width, so the same straps fit either one.
Before you order
A strap on a watch like this only works if it fits properly. There is no hiding a bad fit on a polished 36mm case where every line is visible.
