This watch exudes confidence with its substantial 41mm case diameter, making it suitable for both casual and formal occasions. The grey dial is stunning, offering a subtle yet striking backdrop for the watch's mixed indexes and proprietary hands, which are coated with luminescent material, ensuring visibility in low-light conditions.
