Black and gold is the oldest power palette there is — tuxedos, champagne labels, casino chips — and the Submariner 116618LN wears it better than almost any watch ever made. Solid 18k yellow gold case and bracelet, black sunburst dial, black Cerachrom bezel: where its blue-dial sibling turns heads, this one lowers the lights. From 2008 to 2020 it was the evening-wear end of the Submariner range, and it still is.
And like every solid gold Sub, it lives with one contradiction: the more you love wearing it, the faster that gold bracelet pays the price. Gold marks easily, gold links stretch, and every scratch on a precious-metal bracelet is money. A fitted rubber strap dissolves the contradiction — the watch gets worn like a Submariner, the bracelet retires to the box like an asset.
One click decides the fit: Submariner 40mm
The sizing is simple, and the mistake is common, so here it is up front.
The Submariner 116618LN is a 40mm case with a 20mm lug width. On Helvetus product pages, select Submariner 40mm — that's the entire job. The 41mm option belongs to the current generation, including this watch's direct successor, the 126618LN, which runs 21mm lugs on a reshaped case. Photos won't show you the difference; the lugs will, the moment a wrong-size strap goes on.

The black-tie Submariner
The 116618LN arrived in 2008 as part of a remarkable trio: the two solid gold Subs and the white gold Smurf, which together introduced the scratch-proof Cerachrom bezel and the broad Super Case two years before any steel Submariner had them. The most precious Subs were the technological vanguard.
Underneath the gold, it's pure Submariner: caliber 3135 with about 48 hours of reserve, 300 meters of water resistance, Glidelock clasp, maxi dial with big luminous plots. But the black-on-black-on-gold execution gives it a character no other Sub has. The blue-dial version is a beach watch that owns the daytime; the LN is the one that looks correct with a dinner jacket. Twelve years of production built it a quiet, loyal following — owners who wanted the gold without the color.
Strap logic follows the palette: black and gold set the theme, and every pick either completes it, warms it, or doubles down on it.
Black: the tuxedo, completed
The definitive choice: Black Rolex Submariner Rubber Strap
Black rubber is one of the most popular strap choices among owners of this reference, because it finishes the sentence the watch already started. Dial, bezel and strap merge into one dark, seamless run, and the gold case sits inside it like a cufflink on a black shirt. The bracelet's flash is gone; what remains is pure contrast — arguably the most elegant a Submariner ever looks. Take the deployant version and your original solid gold Oysterlock stays on the wrist, gleaming at the clasp of an otherwise all-black strap. That detail alone sells the swap.
Brown: gold on gold's terms
The warm one: Brown Rolex Submariner Rubber Strap
Brown meets the yellow gold in its own register — warm against warm — and softens the black dial's formality into something closer to vintage luxury. Think gold watch on a leather strap, minus the water anxiety: this is that look, rendered in rubber that shrugs off pools, sweat and sunscreen. On the 116618LN it reads rich rather than sporty, and it's the pick for owners who wear the gold Sub with tailoring more often than with swim shorts.
Yellow: the double-down
The bold one: Yellow Rolex Submariner Rubber Strap
On the blue-dial gold Sub, a yellow strap is a statement. On the black-dial version, it's a composition — the black dial and bezel float inside an unbroken field of gold and yellow, like the reverse of the black strap: instead of gold on black, black on gold. It's the loudest option in this guide and also the most coherent one, because every tone comes straight from the watch. Save it for summer, wear it with confidence, and accept that your Submariner will be the most photographed watch at the table.
Black with Green LuxLine®: casino colors
The knowing one: Black and Green Rolex Submariner Rubber Strap – LuxLine®
Green and gold over black — the palette of card tables and money clips — lands on the 116618LN with a wink. The black base keeps the tuxedo intact while the integrated green centerline adds one precise line of color that plays beautifully against yellow gold. It's subtle at a glance and clever up close, which is exactly the energy this watch runs on. The pick for the owner who already has the black strap and wants a second one with a story.
The rest of the range
The complete color lineup for this watch — including white for a summer reset — lives in the Submariner collection, every strap offered as a deployant version for your original Rolex clasp or with a classic pin buckle: All Rolex Submariner Rubber Straps
Same rule as always: select Submariner 40mm, and everything there fits your 116618LN precisely.
Final thoughts
A solid gold Submariner asks one question every morning: worth the wear today? Rubber changes the answer to "always." The weight drops by a category, the scratch anxiety disappears, and the gold bracelet — the part of this watch that shows age fastest and costs most to show it — stays exactly as it is, waiting for the evenings it was made for. That's not compromising the watch; that's finally using it.
Helvetus keeps the whole switch simple: 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. Black to complete the black-tie look, brown for gold on its warmest terms, and yellow for the days subtlety isn't the assignment.
