Equipped with a Spring Drive mechanism that enables high accuracy equivalent to a quartz watch while using the mainspring used for mechanical watches as a power source.
The case and bracelet have been changed from stainless steel to Bright Titanium, which is approximately 30% lighter and has excellent scratch and corrosion resistance.
The dial has also been updated with a fine striped pattern, giving it an intellectual impression that is suitable for bright titanium.
The three-dimensional Lumibrite index and the newly adopted long hands that maximize the use of the wide dial emphasise the presence and improve visibility.
