Description
A masterpiece from ZF Factory! π₯π₯ Highly recommend the TUDOR Tudor Black Bay 54 37MM watch, a true "small cannon" of luxury diving watches.
γCaseγ37mm diameter, the Black Bay 54 model returns to the original size of the Oyster Prince Submariner, paying homage to the classic Tudor dive watch.
The new Tudor Black Bay 54 watch features beveled lugs. While the winding crown remains at 3 o'clock without a crown guard, its shape and posture have been updated compared to previous Tudor Black Bay collections. The recessed crown also adds to the overall vintage style, looking almost identical to the original and featuring a Tudor rose motif.
γDialγ The dial is exquisitely crafted, featuring a full matte black dial adorned with gold lettering and a minute track. It uses gold-plated hour markers inlaid with a Super-Luminova luminous coating and accented with a touch of patina, adding a vintage warmth. The gold snowflake hands also utilize the same artificial patina.
γStrapγThe new model also features a riveted bracelet inspired by the retro style of the 1950s/1960s, with a very unique stepped structure, but using artificial rivets and solid links, providing a retro look with modern robustness and the convenience of fine-tuning.
The ZF factory Black Bay 54 model is a textbook example of the perfect balance between "fullness" and "slimness." A boon for those with small wrists, it's definitely worth looking forward to!
