Status: Active Investigation
Condition: Good Pre-Owned
Scope: Watch & Warranty Card Only

🔎 Case Notes

The Tudor Black Bay GMT Ref. 79830RB is one of the strongest value propositions in modern travel watches — a robust, full-featured GMT with a charismatic red and blue “Pepsi” bezel, in-house movement, and unmistakable Tudor aesthetics that blend heritage cues with contemporary performance.

Its 41mm case, snowflake handset, and gilt-style dial details give the GMT a warm, vintage-adjacent character, while the bi-color anodized aluminum bezel brings a splash of color that stands out without overwhelming the design. Tudor built the 79830RB as a genuine traveler’s tool: practical, legible, and engineered with durability in mind.

This example is in good pre-owned condition, showing light, natural signs of regular wear consistent with everyday use. The case retains clean lines, the bezel remains vibrant, and the dial is pristine. It includes the Tudor warranty card — an ideal setup for collectors who prioritize authenticity and function over full-box premiums.
