Black Bay GMT

Tudor 2018

ref. 79830RB
Men's

Tudor adds a GMT to its Black Bay line. The second time zone is indicated by a red snowflake hand, a design hallmark of a Tudor watch, that points to the 24-hour graduation on the red and blue bidirectional rotating bezel. The 41mm steel case, water-resistant to 200 metres, houses the new in-house MT5652 calibre. With it, Tudor shows its intention to develop new functions through integrated movements, not as additional modules. As always, its structure is designed for robustness, longevity and reliability; for example, the variable inertia balance is maintained by a sturdy traversing bridge with a two-point fixation. The balance spring is in anti-magnetic silicon, which contributes to the movement's COSC-certified precision.
