{"product_id":"seiko-ssa425j1","title":"Seiko Presage Automatic Open Heart Black Dial Stainless Steel Watch (SSA425J1)","description":"\u003cp\u003eThe Seiko Presage SSA425J1 brings vintage-inspired design into the modern era with a striking open-heart complication that reveals the mechanical soul within. This automatic timepiece features a bold black dial framed by a bi-directional black bezel with rose-gold accents, evoking the sporting chronometers of the 1960s. The open aperture at 7 o'clock offers a mesmerising view of the 4R39 calibre at work, while applied hour markers and a discreet 24-hour subdial at 12 o'clock add both function and visual depth. The round stainless steel case measures 40.5mm in diameter, sized for versatility across wrist profiles, and pairs beautifully with a three-link stainless steel bracelet that balances comfort with refinement.\u003c\/p\u003e\u003cp\u003ePowered by Seiko's reliable 4R39 automatic movement with manual winding capability, this watch delivers approximately 41 hours of power reserve and beats at 21,600 vibrations per hour across 24 jewels. The see-through screw-down case back invites enthusiasts to admire the decorated rotor and movement architecture, while the box-shaped Hardlex crystal recalls the domed profiles of mid-century sports watches. Water resistance to 50 metres provides peace of mind for everyday wear, though this is a timepiece designed more for boardroom confidence than deep-water pursuits.\u003c\/p\u003e\u003cp\u003eAt \u003ca href=\"\/pages\/about-us\"\u003eCassims \u0026amp; Co.\u003c\/a\u003e, we are proud to present the full range of \u003ca href=\"\/collections\/seiko\"\u003eSEIKO watches\u003c\/a\u003e as an authorised retailer, ensuring every piece carries the manufacturer's international warranty and our commitment to aftersales care.
