Matching Your Strap Colour to Each Fifty Fathoms Ocean Edition
No other watch at this price does colour with quite so much nerve. Every Scuba Fifty Fathoms is built around a single idea — one ocean, one palette — and the factory NATO is tuned to that palette down to the stripe. Which is why choosing a replacement is harder than it looks: the watch has already made a strong statement, and the strap either joins the conversation or interrupts it. This guide goes edition by edition through our range of straps for the Fifty Fathoms and explains what each case and bezel combination will actually carry.

Three approaches, two of which work
Match the theme
Take a colour already present on the watch — the bezel, the case, one of the stripes on the stock NATO — and repeat it. Navy on the Atlantic, green on the Indian, grey on the Antarctic. It looks as though the watch left the factory that way and never clashes with what you are wearing. The risk is blandness rather than error: matched too closely, the strap disappears and the watch looks slightly smaller than it is.
Contrast on purpose
The opposite move is a colour that appears nowhere on the watch, committed to fully. Orange under the Antarctic's cool grey. Sand beneath the black bezel of the Ocean of Storms. Contrast pushes the eye towards the dial rather than away from it, which is why it reads as a deliberate choice. The only rule is that it has to be obvious.
The near miss, which never works
An orange strap almost but not quite the orange of the Arctic's bezel. A blue a shade off the Atlantic's case. The eye is very good at detecting a failed match and very poor at reading it charitably — and on this watch more than most, because the factory references are so saturated that any neighbouring shade sits awkwardly beside them. Land the colour exactly, or go somewhere else entirely.
Edition by edition
Atlantic Ocean
Cerulean case, navy bezel, a light blue dial fading between the two. The easiest edition to dress, because the watch supplies a two-tone scheme you can borrow from either end. Navy looks factory-correct; mid-blue picks up the case and makes the watch read lighter. Black flattens the gradient slightly, while white is the sharpest contrast and the one that most clearly looks chosen.
Pacific Ocean
A yellow-orange case under a black bezel, with a greyscale fumé dial. The loudest watch of the original five, and the one that needs most restraint. Black extends the bezel, calms the case and makes the whole thing wearable at work; grey does the same with less weight. Yellow-matched straps are a trap: they double the volume of the element already shouting loudest. For colour, go cool — navy or deep grey-blue.
Indian Ocean
Green case, black bezel, green-and-black gradient dial. This one takes earth tones better than anything else in the range. Khaki, olive and sand all read as deliberate rather than approximate, since none of them is trying to match the dial exactly. Black is the conservative choice and makes the watch noticeably more formal. Avoid bright green: the dial's green is deep and slightly smoky, and a vivid band beside it makes the watch look faded.
Arctic Ocean
Beige case, orange bezel, sandy dial with orange accents. The warmest watch here and the one most owners get wrong, usually by chasing the orange — which only works if it is the same orange, meaning the factory strap. Everything else that works is neutral: beige, taupe, mid-brown, or a textured grey that lets the bezel be the single bright element. Dark brown turns this edition into something close to a vintage tool watch, which suits it unexpectedly well.
Antarctic Ocean
Ice-white case, grey bezel, cool grey dial. The most restrained edition and therefore the most flexible — nothing on the dial is competing, so almost any colour works. Light grey keeps the watch looking like an instrument; black adds definition and makes the pale case read deliberately rather than washed out. If you want one strap that transforms a watch, this is the edition for a strong colour: red, orange and cobalt all land cleanly against grey.
Green Abyss
Deeper and more serious than the Indian Ocean's green, and it wants a strap that respects that. Matched dark green is the most elegant pairing in the whole range, provided the shade is genuinely dark rather than mid-tone. Black is the dependable alternative. Beyond those two the options narrow fast: this is not an edition that enjoys bright contrast, and warm neutrals tend to look muddy against a cold green.
Ocean of Storms
The most assertive of the recent arrivals, and the only one that genuinely suits black on black. Graphite, ribbed black and dark grey all work, because texture carries the interest where colour would be excessive. To lift it, sand or pale grey is the move — a light band under a dark dial is a classic diver combination and makes the case look larger.
Blue Lagoon and Pink Ocean
Both are built around a single bright colour, so they behave like the Pacific: the strap's job is to hold the watch together rather than add to it. White and light grey are the reliable choices, black if you want the colour to look sharper, and a matched band only if the shade is exact. The straps sorted by ocean edition are grouped on that principle, which saves working through the whole range for every watch.

Material changes the colour more than you expect
The same shade behaves differently across materials, and most owners discover this only after buying. Smooth rubber reflects light, so a colour reads one or two steps brighter than it did in the photograph. Matte and ribbed rubber absorb light and read deeper, which is why a black band can look anywhere between charcoal and ink on finish alone. Canvas and nylon are flatter again, and the weave mixes the colour with a little shadow, so a navy weave looks closer to slate.
There is a consequence specific to this watch. The factory straps are striped, and moving to plain rubber removes the visual break those stripes provide — the watch suddenly looks more monolithic. If that is not what you want, a striped or two-tone NATO strap for the Fifty Fathoms keeps the original idea while changing the palette, and pass-through construction suits a case rated to 9.1 bar.
Three neutrals that work on every edition
If you would rather not think about it, three colours go on every edition without a misstep. Black is the most formal and most reliably office-appropriate. Mid-grey is the quietest and the best at letting a loud dial be the point. Navy sits between the two: dark enough to read as neutral at arm's length, with enough colour to look intentional in daylight. Be more careful with white, which looks superb for a fortnight and then needs real maintenance, and with anything metallic, which fights the bioceramic's matte finish.
One strap, several watches
The case is identical across every edition: 42.3mm across, 14.4mm deep, 48mm lug to lug, with the same 22mm fitting and the same screw bars. A strap bought for the Atlantic fits the Arctic and the Ocean of Storms without modification, which changes the arithmetic if you own two — two watches and three straps give six combinations, and both factory NATOs stay unworn in their boxes.
One caution on the swap: screw bars need two 0.9mm hex drivers and an unhurried five minutes, and a driver that slips leaves a mark on bioceramic that will not polish out. Work on a cloth and keep the driver square.
Frequently asked questions
Should I match the strap to the dial or the bezel?
The bezel, in most cases. It is the larger block of flat colour and the element people see first, and matching a gradient dial is close to impossible anyway.
Is it a mistake to use a colour that is not in the edition's palette?
No, provided the difference is obvious. A clean contrast looks chosen; a shade that nearly matches looks like an error.
What single strap colour suits the most editions?
Mid-grey. Neutral enough for the loud editions, dark enough to give the pale ones definition.
Do all the ocean editions take the same strap?
Yes. Every edition shares the same case dimensions and a 22mm fitting with screw bars, so straps rotate freely between them.
Can I keep the factory NATO and buy just one spare?
You can, though most owners end up doing the reverse: the spare becomes the daily band and the original is kept unworn.
Match it, or change it properly
Colour is the whole point of this watch, which makes the strap a bigger decision here than on a plain black diver. The approach that fails is the cautious one — a shade that nearly matches, chosen to avoid a mistake, which is itself the mistake. Pick the bezel colour and repeat it, or pick something unmistakably not on the watch and commit to it. Keep one neutral for the days you want the watch to behave, remember that finish shifts a colour as much as the dye does, and accept that you will probably end up with three bands rather than one. On a watch built around a palette, that is simply how it is meant to be used.
