The Tudor Black Bay GMT Ref. 79830RB brings together Tudor’s vintage-inspired design language with the practical functionality of a true travel watch. Instantly recognizable by its red and blue “Pepsi” bezel, this model has become one of the most popular references within the modern Tudor lineup.
The anodized aluminum bezel allows the wearer to track multiple time zones, making it especially useful for travelers or collectors who regularly coordinate across regions. The dial remains clean and highly legible, with Tudor’s signature snowflake hands and luminous markers providing excellent contrast.
The watch carries the rugged tool-watch presence the Black Bay series is known for, while still maintaining balanced proportions that work comfortably for everyday wear. The steel bracelet complements the case design and gives the watch a strong, cohesive profile on the wrist.
This example dates to 2021 and is presented in very good pre-owned condition, showing normal signs of careful wear consistent with regular use. The dial and sapphire crystal remain clean, and the case retains strong lines.
