The GMT-Master II “Sprite” (ref. 126720VTNR) is one of those Rolex releases that instantly split the room, and that’s exactly why it’s fun. The green and black bezel is classic Rolex GMT language, but the left-handed crown and flipped layout make it feel slightly rebellious on the wrist. It wears like a proper tool watch, yet it still has that polished Rolex sharpness that keeps it from feeling purely utilitarian.
If you’re the kind of person who already likes the Sprite, you probably also know the bracelet isn’t always the vibe. Summer, travel, humidity, long flights, workouts, or just wanting the watch to feel a bit more casual. That’s where a fitted rubber strap makes the GMT-Master II feel like a different watch without turning it into a costume.
Strap size and fit on the 126720VTNR (the part that saves you from ordering the wrong one)
The GMT-Master II 126720VTNR is a 40mm case, and it uses a 20mm lug width. That 20mm detail matters more than people think, because “close enough” straps always look off on a Rolex. You want the strap to sit cleanly between the lugs with no weird daylight peeking through.
On Helvetus product pages, select the option for Rolex GMT-Master II (40mm / 20mm). That’s the correct pick for the Sprite reference, and it’s the one that matches how the case is shaped. If you select something else because it sounds similar, you’ll usually notice it immediately at the lugs, and that’s the kind of mistake that annoys you every time you glance down.
One more practical note: Helvetus offers these straps in deployant and pin buckle versions, so choose based on how you wear your watch. Deployant feels more “Rolex-ish” and secure for daily use, while a pin buckle is slightly lighter and more casual, especially if you’re swapping straps often.
Best strap choices for the Rolex Sprite
Green is the obvious first stop, and honestly, it’s the one I’d recommend if you want the Sprite to look intentional rather than just “on a strap.” The bezel already gives you that green pop, so a green fitted rubber strap ties the whole watch together and makes the black dial feel even sharper. It also leans into the sporty travel-watch vibe, which suits the GMT-Master II’s personality. If you’re wearing the Sprite as a daily, green is the choice that makes it feel like your watch, not just the watch Rolex sold you.

Then there’s the Black/Green LuxLine®, which is for people who like details but don’t want the strap to shout. On the Sprite, the LuxLine® look works because it echoes the bezel color without copying it. The watch stays clean and mostly black from a distance, but up close it feels more considered, like you actually thought about how the strap interacts with the bezel. It’s also the easiest way to make the Sprite feel a bit more refined while keeping it sporty. This is the one I’d wear for “nice casual” situations where you still want the watch to feel like a Rolex.

Black is the safest option, but not boring on the Sprite. It calms everything down and lets the green-black bezel do the talking. If you sometimes feel the Sprite is a little loud on bracelet, black rubber tones it into something you can wear anywhere, including days when you’re dressed in all black or you just want the watch to feel low-key. It also makes the case proportions look slightly more compact, which I like on a 40mm Rolex when you’re going for a stealthy, everyday setup.

If you want to browse beyond those three, it’s worth spending a minute on the GMT-Master II collection because there are plenty of color options, and the straps come in both deployant and pin buckle versions depending on how you prefer to wear your Rolex.
All Straps for GMT Master II
Buying the right strap from Helvetus without overthinking it
The key with the GMT-Master II is getting a strap that looks like it belongs there. The Sprite is a modern Rolex with crisp case lines, and a strap has to match that clean fit at the lugs or it instantly looks like an afterthought. That’s why I like going through the dedicated GMT-Master II collection page: it keeps you in the right lane, and you’re picking straps that are made to sit properly on this model.
If you’re deciding between deployant and pin buckle, think about how you actually live with the watch. Deployant tends to feel more secure and more “integrated” day-to-day. Pin buckle feels simpler, a touch more relaxed, and it’s great if you’re the type who swaps straps based on mood.
The part that matters long-term
A strap only becomes a “good” strap after weeks of wear, not five minutes after unboxing. What I like here is the straightforward confidence: the straps are designed for a precise fit on the Rolex GMT-Master II case, they’re backed by a lifetime warranty, and you’re not getting nickeled-and-dimed with shipping or surprise import costs. Add the fact that Helvetus has been trusted by 30,000+ customers worldwide, and it becomes the kind of purchase you make once and then forget about, in a good way. You just wear the Sprite more.
