SEIKO PRESAGE COCKTAIL TIME OPEN HEART AUTOMATIC 2 TON GOLD BLUE

Best description:
A refined Seiko Presage automatic dress watch featuring a deep blue sunburst dial with a circular open-heart aperture at 9 o’clock that reveals the oscillating balance wheel of the movement. Applied gold-tone faceted hour markers and dauphine hands contrast elegantly against the blue dial, while a date window sits at 3 o’clock. The polished two-tone (stainless steel + gold PVD) case and matching bracelet give it a classic, versatile look ideal for formal or smart-casual wear. An exhibition caseback provides a full view of the movement from the reverse.
This model shares the same elegant Cocktail Time design language as the popular silver-dial SSA358, but with a richer blue dial for a more dramatic presence.
