A distinctive and increasingly popular variation of the Black Bay GMT, the opaline (white) dial offers a fresh and highly legible take on Tudor’s dual-time sports watch. The lighter dial contrasts sharply with the black and burgundy bezel, giving the watch a more contemporary and versatile feel compared to the traditional black dial version.
The 41mm steel case and robust construction maintain the tool-watch heritage of the Black Bay line, while the GMT functionality allows for easy tracking of multiple time zones — ideal for both travel and everyday use.
This example is presented in mint condition, showing virtually no signs of wear. The case and bracelet remain sharp, and the watch is running as expected.
Supplied as a full set, the watch includes inner and outer boxes, warranty card, booklets, and tags.
Powered by Tudor’s in-house MT5652 movement, the watch offers a 70-hour power reserve along with reliable and precise GMT functionality.
All watches are photographed in-house with full transparency — any visible wear is shown clearly in the images.
