The Seamaster Diver 300M “No Time To Die” is one of those modern Omegas that instantly feels like a future classic. Titanium case, muted tones, that slightly aged vibe without trying too hard, and a silhouette everybody recognises from across the room. Ref. 210.90.42.20.01.001 is also a very wearable kind of “special” watch. You can baby it, sure, but it’s way more fun when it’s actually on your wrist, living a life.
And that’s exactly why straps matter so much on this one. The watch is stealthy by nature. The wrong strap can make it look cheap or oddly dressy. The right strap makes it look like it was always meant to be worn that way.
Strap size and fit, don’t mess this part up
This model is the 42mm Seamaster Diver 300M in titanium, and it uses a 20mm lug width.
That single number, 20mm, is the one that saves you from the classic mistake: ordering a strap that “almost” fits, then forcing it, then getting annoyed, then returning it. Don’t do that to yourself.
When you’re on a Helvetus product page, you simply need to choose size 20mm. That’s the correct option for Ref. 210.90.42.20.01.001, and it keeps everything looking clean and properly seated between the lugs, the way it should.
The best strap choices for the No Time To Die Seamaster
The No Time To Die Seamaster is all about tone. The dial is dark, the case is matte titanium, and the whole watch leans “tool” even when you’re just wearing it with a hoodie and sneakers. So I always think in contrasts and textures, not loud colours.
If you want the most “belongs on the watch” look, the Silver Steel strap is a surprisingly strong move. Titanium and stainless steel aren’t the same, but visually, the cooler metal bracelet vibe works perfectly with the grey-black palette of the NTTD. It gives the watch a more purposeful, everyday feel, especially if you’re the type who wants one strap that just works for everything from flights to meetings to a late dinner.
Here’s the one:
Steel Strap for Omega 007
Now, if you want to lean into the Bond vibe without looking like you’re wearing a costume, brown rubber is the sleeper pick. On paper it sounds odd: brown on a black dial diver. In real life it looks warm, rugged, and intentional, like worn leather but with the practicality of rubber. It also plays really nicely with the “tropical” accents on the dial and lume. It’s the strap I’d choose if you wear this watch a lot in daylight, travel, or anywhere casual where you still want it to look elevated.
Omega Seamaster 300 Brown Rubber Strap
For a sharper, sportier look, Black and White LuxLine® is the one that makes the dial pop. The watch is already monochrome and tactical; the white detail adds structure and contrast without turning it into a fashion strap. It feels modern, and it suits the proportions of the 42mm case really well. This is also the strap that looks best when the watch is photographed, which matters more than people admit.

And because the Seamaster NTTD can swing from “beach watch” to “smart casual” in about five seconds, it’s worth knowing you’re not locked into one vibe. If you want to browse options, Helvetus keeps the full range for this model together here:

Buying the right strap from Helvetus, without overthinking it
The practical rule is simple: choose 20mm, then choose the style that matches how you actually wear the watch.
If you’re wearing the No Time To Die Seamaster as your daily, the metal strap vibe is hard to beat. If you want comfort and a softer, more vintage-leaning look, brown rubber is the easy win. If you like crisp contrast and a more modern edge, LuxLine® is a very clean match for this reference.
The main reason I point people to the Helvetus Seamaster collection page is that it keeps you in the right lane. You’re shopping straps designed to sit correctly on this case, not generic “20mm straps” that technically fit but look slightly wrong once installed.
The part that actually matters long-term
A strap isn’t exciting for the first five minutes. It’s exciting after three months, when it still fits properly, still feels good, and still looks right with the watch. That’s why Helvetus works well for this specific Seamaster: the straps are designed for a precise fit on the Seamaster Diver 300M No Time To Die 210.90.42.20.01.001, they’re backed by a lifetime warranty, and you get free worldwide shipping with no import costs, which honestly removes a lot of friction. Add the fact that Helvetus is trusted by 30,000+ customers worldwide, and it becomes the straightforward choice if you want to wear your Omega more, not babysit it.
