The 116621 is the Yacht-Master that finally got Everose. Rolex had done the line in steel and platinum, in yellow gold two-tone, in full gold — but until this reference arrived, it had never combined 904L steel with its own pink gold alloy. Pair that with the chocolate sunburst dial it launched on, and you get one of the warmest-looking sports watches Rolex has ever put out.
It's also a watch with a slightly awkward life. The Yacht-Master is nominally a nautical watch, and this particular one is beautiful enough that most owners keep it well away from anything nautical. A strap is the easiest way to resolve that.
Strap size and fit for the Yacht-Master 116621
The 116621 is a 40mm case with a 20mm lug width, and it takes standard spring bars.
The Yacht-Master line uses three different widths depending on case size, which is where people go wrong. On Helvetus product pages, select the 40mm option and you're correct:

Two things to check before you order:
- If yours is a 42mm (226659 and family), that's a different case and a wider width — don't order from this guide.
- If yours came on an Oysterflex rather than a metal bracelet — the 116655 and 126655 — these curved straps aren't for you. That's a separate system entirely, and the Oysterflex replacement line is where you want to be.
Both buckle versions exist. The deployant version works with your original Rolex deployant clasp, which on this reference is the Oysterlock that came on the bracelet, so the watch keeps closing the way it always has. The pin buckle version includes its own steel buckle and is the lighter option.
What makes the 116621 different
Rolex introduced it at Basel in 2016 and built it until the 126621 took over. Inside is the calibre 3135, the 40mm case is 100 m water resistant with a Triplock crown, and it sits around 12mm thick with a 47mm lug-to-lug — flat and easy on the wrist for a sports Rolex.
Rolesor means the gold goes on specific parts. On this one it's the bezel and the polished centre links of the Oyster bracelet. And here's the detail most owners never notice until someone points it out: the winding crown on the 116621 is steel, not gold — unusual for a Rolesor, where the crown is normally gold, and shared with the yellow gold two-tone 16623 that preceded it.
The bezel deserves a mention on its own. It's Everose with a sandblasted surface and polished raised numerals standing proud of it, which is why the Yacht-Master bezel catches light differently to every other Rolex bezel.
Most 116621s are the chocolate sunburst dial the reference launched with, with applied gold markers and the Yacht-Master text in red. Black-dial examples exist too. They trade around $13,000–$14,000.
Why this reference works better on rubber than most
The gold that scratches is the gold that leaves. The bezel is sandblasted, so it wears quietly — matte surfaces hide hairlines. The polished Everose centre links do the opposite: they're soft, they're mirror-finished, and they sit exactly where your wrist meets a desk. Put the watch on rubber and you've removed the one gold surface that shows every mark, while the bezel — the part everyone actually looks at — stays where it is.
And it concentrates the design. With the bracelet off, all the remaining gold on the watch collects into a single ring around the dial. Steel case, chocolate dial, one Everose bezel. It reads cleaner and, honestly, more expensive than the full two-tone bracelet does.
Then there's the obvious one. It's a Yacht-Master. It's rated to 100 metres, the bezel is built for timing, and most of them never get closer to water than a wine glass because nobody wants to soak a two-tone gold bracelet. Rubber is the strap that gives the watch its brief back.
Four strap colours for the 116621
1. Brown — the chocolate dial's own colour
Start here if you have the chocolate dial, because this is as close to a designed-in combination as an aftermarket strap gets. Brown rubber continues the dial straight down the wrist, the Everose bezel sits between the two as the bright element, and the steel case almost disappears.
It's the single best-looking thing you can do to this reference, and it costs less than a bracelet link.

2. Beige — the lighter warm option
Same idea, turned down. Beige gives you the warm-on-warm pairing without the density of brown, and it flatters Everose in daylight in a way darker colours can't — the gold reads pinker against a pale strap.
This is the summer version of the brown, and it's the one that works whether your dial is chocolate or black.

3. Black — the contrast play
Black does the opposite job: instead of blending with the gold, it isolates it. Against a black strap the Everose bezel becomes the only warm thing in the frame and gets noticeably louder, while the steel case sharpens up.
If your 116621 is one of the black-dial examples, this is the like-for-like choice and the most wearable strap in the range.

4. Navy — the nautical one that actually behaves
Navy and rose gold is a combination that works for the same reason navy and gold buttons work, and on a watch designed around sailing it's the most contextually correct colour on the list without being a costume.
It's darker and more serious than a bright blue, which matters here — a loud blue would fight the chocolate dial. Navy sits underneath it.

The rest of the range, including white, grey, light blue and the LuxLine® options, is in the Yacht-Master collection — just remember to select the 40mm option.

Quick answers
What lug width is the Rolex Yacht-Master 116621? 20mm. The case is 40mm and it uses standard spring bars.
What do I select when ordering? The 40mm option. The 42mm and 37mm Yacht-Masters use different widths.
Will the strap work with my original clasp? Yes — the deployant version is made to work with the original Rolex deployant clasp. The pin buckle version comes with its own buckle if you'd rather leave the clasp alone.
Is the 116621 the same fit as the 126621? Yes. Both are 40mm Yacht-Masters with a 20mm lug width, so the same straps fit either one.
Before you order
The 116621 is a watch a lot of people own and under-wear, because two-tone gold on a bracelet always feels like it deserves an occasion. A strap removes that problem entirely, and it protects the softest metal on the watch while it does it.
Helvetus straps for the Yacht-Master are cut for this case, come with a lifetime warranty on rubber, ship free worldwide with no import costs, and are worn by 50,000+ customers. Chocolate dial, Everose bezel, brown rubber — go and look at that combination once and you won't put the bracelet back on until winter.
