Every Rolex on rubber owes something to this watch line. When the Yacht-Master 40 in Everose gold appeared in 2015, it was the first Rolex ever fitted with the Oysterflex — the strap that made rubber officially acceptable on a precious-metal Rolex. The 126655 is the current keeper of that idea: a solid 18k Everose gold case, matte black Cerachrom bezel with raised polished numerals, and factory rubber on the wrist as standard. Rubber isn't a modification on this watch. It's the native language.
Which makes the strap question more natural here than on almost any other Rolex. This guide covers exactly how replacement sizing works for the 126655, and which strap colors do the most for a rose gold case built around life on the water.
Which size fits the Yacht-Master 126655?
The 126655 has a 40mm case with a 20mm lug width. On our Oysterflex replacement straps, select the 20 mm lug width option, then choose the length of each side independently — 50 mm, 60 mm or 70 mm per side. The strap comes as two separate pieces, exactly like the original, so most owners simply match the lengths of their current setup, or pair one longer and one shorter side to center the clasp.
Your 18k Everose Oysterlock clasp stays on the watch: the strap is designed to connect directly to your original clasp, and your factory spring bars carry over as well (fresh spring bars are included too).
Three sizing warnings to keep orders clean. The larger Yacht-Master 42 on Oysterflex — the yellow gold 226658, white gold 226659 and titanium 226627 — takes the 21 mm option instead; we've covered the white gold separately in the Yacht-Master 42 226659 guide. The 37mm Everose model (268655) has a much narrower fit and is not compatible with this strap, so please don't order the 20 mm for it. And if your Yacht-Master 40 is on the metal bracelet — the Rolesium 126622 or two-tone 126621 — you need our curved Yacht-Master straps instead, covered in the Yacht-Master 126622 guide.
A short history of the 126655
The Yacht-Master has been Rolex's regatta-flavored sports watch since 1992, but 2015 is the year that matters here: the Everose Yacht-Master 40 introduced the Oysterflex to the world — elastomer outside, flexible metal blade inside — and quietly changed what a gold Rolex was allowed to be. In 2019 the reference was renewed as the 126655, bringing the caliber 3235 with its 70-hour power reserve, Chronergy escapement and modern anti-magnetic architecture.
The formula stayed intentionally pure. A case made entirely of Everose, the rose gold alloy Rolex casts in its own foundry so the color never fades. A matte black Cerachrom bezel whose polished raised numerals are the only shine on an otherwise stealthy front. A matte black dial with Chromalight markers, or a factory pavé diamond dial for those who want the jewelry version. And the Glidelock extension in the clasp, because a watch meant for the water should adjust over a wetsuit sleeve — or just a warm afternoon.
Collectors love the 126655 for the same reason it needs this guide: it's the gold Rolex you actually wear. Poolside, on deck, through summer — this reference lives outdoors. That's a lot of sun, salt and sunscreen for one factory rubber strap, which only exists in black, is a wear part by nature, and is neither quick nor cheap to replace through official channels. A replacement strap keeps the original Oysterflex fresh for the full set the next owner will ask about, and finally gives the watch that invented gold-on-rubber more than one color to wear it in.
The best rubber straps for the Rolex Yacht-Master 126655
Four picks, chosen the way this watch was designed — around the water, and around what Everose gold pairs with best.
1. Black — the factory look, renewed. The black FKM rubber strap is the most popular choice for this model, and on the 126655 it's practically canon: black rubber, black bezel, black dial, warm Everose in between. It restores the exact factory character with fresh rubber underneath, which is why so many owners keep one mounted for daily wear while the original stays boxed. If the goal is "my watch, but always looking new," this is the answer.
2. Blue — the sailing pick. A Yacht-Master belongs near water, and a blue FKM rubber strap puts the water on the wrist. Deep blue against Everose gold is a classic nautical pairing — rich, warm-meets-cool, and somehow more "yacht" than the factory black. It flatters the black dial, makes the rose gold glow, and turns the watch into the obvious choice for every harbor dinner from May to September.
3. White — rose gold's summer uniform. White rubber on an Everose case is one of the best-looking combinations in the entire sports-Rolex world, and the white FKM rubber strap proves it. Crisp against the warm case, sharp against the black bezel — it's the deck-shoes-and-linen version of this watch, and in strong sunlight it simply looks expensive. If the black strap is the 126655's weekday, white is its holiday.
4. Red — the regatta flag. Red and Everose share the same warmth, which is why a red FKM rubber strap works here when it would overpower a steel watch. Saturated red pops beautifully against a rose gold case and black dial, and on a watch named after yacht racing, a signal-flag red strap feels less like a novelty and more like a nod to the sport. It's the confident pick — one of those combinations people stop you to ask about.
Every one of these connects to your original Everose Oysterlock clasp using the 20 mm sizing described above. The rest of the range — turquoise, light blue, green, orange and grey — lives in the Oysterflex replacement collection.
