M79830RB is one of the strongest modern travel watches in Tudor’s lineup — a watch that takes the core Black Bay design language and gives it true GMT functionality with the classic burgundy-and-blue bezel that earned it the “Pepsi” nickname. At 41mm, it has enough presence to feel like a proper sport watch, but the proportions remain balanced enough for daily wear. The reference is built around a 41mm steel case, domed dial, sapphire crystal, in-house GMT movement, and 200m water resistance. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"874\" data-end=\"1275\"\u003eWhat makes this reference especially appealing is its balance of utility and familiarity. The bidirectional 24-hour bezel and jumping local hour hand make it genuinely useful for travel, while the black dial keeps the overall look grounded and versatile. On Oyster bracelet, it feels especially direct and wearable — a strong everyday configuration for one of Tudor’s best-known modern GMT references.\u003c\/p\u003e\n\u003cp data-start=\"1277\" data-end=\"1531\"\u003eThis example dates to \u003cstrong data-start=\"1299\" data-end=\"1307\"\u003e2020\u003c\/strong\u003e and is presented in \u003cstrong data-start=\"1328\" data-end=\"1361\"\u003eexcellent pre-owned condition\u003c\/strong\u003e.
