Every Submariner makes a statement. The 116618LB makes an announcement. Solid 18k yellow gold from lug to clasp, a sunburst blue dial, and a blue Cerachrom bezel that turns the whole watch into one warm, glowing object — this is the Sub for people who long ago stopped pretending they wanted subtle. From 2008 to 2020 it sat at the top of the Submariner range, and on the wrist it still owns every room it enters.
It also has the strongest case for a rubber strap of any watch in this catalog, and it's not about style first. A solid gold Oyster bracelet is heavy, it's soft — gold scratches and stretches faster than steel — and it represents a serious amount of precious metal that loses value with every mark. Put the bracelet in the box, put the watch on rubber, and you get to actually wear the gold Sub instead of managing it.
Sizing before shopping: this gold Sub is a 40mm
The fit comes down to one selection, so let's nail it immediately.
The Submariner 116618LB is a 40mm case with a 20mm lug width. On Helvetus product pages, the option to select is Submariner 40mm — full stop. The 41mm option is for the post-2020 generation (including this watch's successor, the 126618LB), which uses 21mm lugs. The two gold Subs are near-twins in photos and completely different at the lugs, so don't let the resemblance fool you at checkout.
116618LB → 40mm → 20mm → select Submariner 40mm. Locked in? Good — every strap below now fits your gold case flush, with no gaps.
2008: the year the Sub went ceramic — in gold first
Here's a piece of trivia that surprises even Submariner people: the modern ceramic Sub didn't start with the steel models. It started here. In 2008, Rolex introduced the 116618LB alongside its white gold sibling, debuting the scratch-proof Cerachrom bezel and the broad "Super Case" a full two years before the steel 116610LN existed. The most luxurious Submariner was also the most advanced one.
Beyond the gold, it's all proven Submariner machinery: caliber 3135 with roughly 48 hours of reserve, 300 meters of water resistance, Glidelock clasp, maxi dial with oversized luminous markers. Twelve years of production later, the 116618LB stands as the definitive gold-and-blue Sub — collectible, unmistakable, and warm in a way no steel or white gold reference can imitate. Which brings us to strap logic: where cooler Subs want restraint, yellow gold rewards color and confidence. These four deliver.
Blue: let the gold burn against it
The essential pick: Blue Rolex Submariner Rubber Strap
Blue is one of the most popular strap choices among owners of this reference, and one look explains it: matching the dial and bezel wraps the watch in a single band of color, and the yellow gold case suddenly has nothing to compete with. The gold doesn't just stand out against blue — it ignites against it. The watch loses the bracelet's weight, keeps every bit of its presence, and gains the kind of coherent, styled look that makes people assume the strap came from the factory.
Start here. Most owners never need a reason to leave.
Brown: the connoisseur's warm-up
The refined one: Brown Rolex Submariner Rubber Strap
Brown and yellow gold have been a pairing since long before wristwatches — it's the color language of old-money leather goods, and on the 116618LB it works exactly that way. The warm strap flows into the warm metal, the blue dial becomes the single cool accent, and the whole watch shifts from "statement diver" to "heirloom you happen to swim in." The deployant version fits your original clasp, so the solid gold Oysterlock stays on the wrist — gold at the case, gold at the clasp, rich brown in between.
Yellow: all-in on gold
The full send: Yellow Rolex Submariner Rubber Strap
If you bought a solid gold Submariner, somewhere in you lives a person who doesn't do half measures — and this strap is for that person. Yellow rubber under a yellow gold case creates one continuous statement of intent: the blue dial and bezel float in the middle of it like a jewel in a setting. Is it loud? Gloriously. But it's also coherent in a way random bright straps never are, because the color comes straight from the watch itself. Summer parties, beach clubs, anywhere the gold Sub was always going to be noticed anyway — lean in.
White: the yacht-club setting
The crisp one: White Rolex Submariner Rubber Strap
White is what happens when the gold Sub goes on holiday. Against a clean white strap, the yellow gold reads brighter and the blue reads deeper — the classic gold-white-navy palette that has dressed boat decks for a century. It's the freshest the 116618LB ever looks, it pairs with linen and white sneakers like they were designed together, and it keeps a very expensive watch feeling light and effortless in exactly the settings where you'll wear it most. Also available for the original gold clasp in the deployant version.
One collection, every color
Those four are the strongest matches for the gold-and-blue formula, but the full range — including classic black for the days you want the volume down — lives in the Submariner collection, each strap offered as a deployant version for your original Rolex clasp or with a pin buckle: All Rolex Submariner Rubber Straps
The rule travels with you: select Submariner 40mm, and everything there fits your 116618LB perfectly.
Final thoughts
Here's the honest math on a gold Submariner: the bracelet is a large part of the watch's value, gold shows every scratch, and stretch on a solid gold Oyster is expensive in every sense. A fitted rubber strap flips the equation — the watch gets worn more and worried about less, while the bracelet waits in the box in the condition collectors pay for. Comfort today, value preserved for tomorrow. There aren't many upgrades in watches that work in both directions at once.
Helvetus keeps the swap risk-free: straps engineered for a precise fit on this exact Submariner generation, a lifetime warranty on every rubber strap, free worldwide shipping, and no import costs at checkout — trusted by more than 50,000 customers worldwide. Blue to make the gold blaze, brown to make it whisper, yellow to make it sing, and white for the days the sun does half the work.
