There are a lot of “icon” Rolexes, but the GMT-Master II has a different kind of swagger. It is not just a pretty face with a famous bezel. It is a proper travel watch that somehow also became a style shortcut. And the 126710BLRO Pepsi is the one people spot from across a room, whether they admit it or not.
The case is the modern 40mm Rolex sports template, but on wrist it wears crisp and tidy rather than bulky. That Jubilee bracelet is part of the charm, sure. Still, the moment you put the watch on rubber, the whole vibe shifts. It gets a little more purposeful, a little less “I am trying”, and a lot more comfortable in heat.
Strap size and fit (so you do not order the wrong one)
For the Rolex GMT-Master II 126710BLRO Pepsi, you are working with:
-
Case size: 40mm
-
Lug width: 20mm
That 20mm lug width is the number that matters when ordering. On Helvetus product pages for the GMT-Master II, you do not need to overthink it. Choose the strap you like, and it will fit the Pepsi.
The only real “choice” you should focus on is practical:
-
Pick your strap color
-
Pick your buckle style (we offer deployant and pin buckle versions)
If you are buying specifically because you want the clean, integrated look, the good news is simple: our GMT-Master II straps are designed to fit this model properly, so you are not gambling on a generic straight-end strap that leaves awkward gaps at the case.
If you are the type who keeps multiple straps around, I would personally lean deployant for daily rotation because it is quick on and off and tends to be gentler on the strap over time. Pin buckle is classic, lighter, and feels more “tool watch.” Neither is the wrong answer, it is more about how you actually wear your watch.
The best strap choices for the Rolex GMT-Master II Pepsi
The Pepsi bezel does most of the talking. The trick with straps is not competing with it. You want the strap to either calm the watch down or deliberately echo one of those bezel colors without turning the whole thing into a costume.
Black LuxLine® with Blue line
Black/Blue LuxLine® Rubber Strap for GMT Master II
This one makes a ton of sense if you wear the Pepsi as an everyday watch and want it to feel a little more modern. The black keeps the overall look grounded, while the blue line quietly mirrors the bezel’s blue half without screaming for attention.
It is also the strap I would pick for a watch that sees real use: travel days, airport security, hot weather, a lot of wrist time at a laptop. The blue detail adds personality, but it still reads “serious” on wrist.
Black LuxLine ® with Red line
Black/Red LuxLine® Rubber Strap for GMT Master II
If you like the Pepsi because it is bold, this strap leans into that reason in the best way. The red line is a small move that makes the watch look sharper and more intentional, especially in natural light where the bezel already pops.
I tend to think this is the more fun choice for weekends, dinners, and anything social. It also pairs surprisingly well with simple outfits. White tee, dark jeans, sneakers, Pepsi on red-accented rubber, done. It looks like you meant it, but you are not trying too hard.
Classic Black
Black Rubber Strap for GMT Master II
Sometimes the smartest answer is the boring one, and I mean that as a compliment. A clean black rubber strap turns the 126710BLRO into something that feels closer to a functional travel instrument than a collectible. You still get the Pepsi bezel character, but the strap stops the watch from becoming too “look at me.”
Black is also the safest pick if you swap between different settings in the same week. It works with business clothes, it works with gym clothes, and it does not clash with anything. If you only buy one strap first, black is the one that rarely disappoints.

The best part about shopping straps for the GMT-Master II is that the fit question is simple. You are not chasing odd lug widths or weird case shapes. You just need a strap built for the GMT-Master II profile so it sits flush and looks right.
That is why I always point people to the GMT-Master II collection page when they ask what to pick. It keeps you inside the correct fit family, and then you can focus on what actually matters: color choice and whether you prefer deployant or pin buckle for your routine.

A quick, honest wrap-up
The Rolex GMT-Master II 126710BLRO is already a strong watch. A good strap should not fight that. It should make the watch easier to wear, more comfortable in heat, and more “yours” without ruining the proportions.
That is the whole point of the Helvetus approach here: straps designed for a precise fit on this specific GMT-Master II case, backed by a lifetime warranty, with free worldwide shipping and no import costs so the checkout total is not a surprise later. And considering how many wrists these have ended up on, being trusted by 30,000+ customers worldwide is not a marketing line, it is just the reality of a strap that people actually live with day to day.
