When Rolex unveiled the GMT‑Master II Reference 126713GRNR in 2023, the watch community immediately gave it a memorable nickname: the “Zombie.” Why? Because of its unique grey and black Cerachrom bezel, which gives this two‑tone classic an almost eerie, understated look that stands out from the crowd.
Whether you’re a seasoned collector or just discovering Rolex’s GMT lineup, this watch perfectly blends iconic Rolex heritage with contemporary flair and modern functionality.
What Makes the “Zombie” So Special?
At first glance, the Rolex GMT‑Master II 126713GRNR is unmistakable. It’s crafted from Rolesor, Rolex’s signature blend of Oystersteel and 18k yellow gold, delivering both durability and luxury in one package.
But what really sets it apart and gave rise to its nickname, is the muted grey and black ceramic bezel insert. Unlike the vibrant red‑blue or green‑black bezels seen on other GMT models, this two‑tone Cerachrom bezel has a subdued, almost “undead” aesthetic that collectors affectionately call the Zombie, a nod to its more chilled‑out color palette.
In some circles you’ll also hear it referred to as the “Bumblebee” highlighting the vibrant contrast between the dark bezel and the rich yellow gold accents.
Designed for Global Travelers
The GMT‑Master II series was originally developed for pilots and world travelers, and the Zombie continues this heritage with the Caliber 3285 automatic movement, offering a dual‑time function that makes tracking multiple time zones effortless.
Here’s what that means in everyday terms:
- A 24‑hour hand shows a second time zone at a glance.
- The rotatable bezel lets you adjust to a third time zone if needed.
- Rolex’s ingenious mechanism lets you set the local time independently without stopping the watch — ideal for frequent flyers.

The Zombie stands apart thanks to its grey tone, giving it a personality that’s subtler and more modern, while still rooted in the classic GMT aesthetic.
