SEIKO PRESAGE COCKTAIL TIME OPEN HEART AUTOMATIC 2 TON GOLD WHITE

Seiko Presage SSA358 (Open Heart / Cocktail Time series) — Two-tone automatic dress watch
Best description:
An elegant Seiko Presage automatic with a striking open-heart design. It features a radiant silver-white sunburst dial with a circular aperture at 9 o’clock that reveals the oscillating balance wheel of the movement in real time. Applied gold-tone faceted hour markers and dauphine hands complement the 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 refined, dressy look suitable for formal or smart-casual wear. An exhibition (see-through) caseback lets you view the movement from the reverse side as well.
