Celebrated worldwide among horology enthusiasts, vintage dress watch collectors, and everyday wear aficionados by its series nicknames—the \"Style 60s Open Heart\", \"Presage Style60's\", \"1964 Crown Chronograph Tribute\", or \"Retro 60s Open Heart\"—this 40.8mm watch channels the nostalgic elegance and mid-century aesthetic of Japan's first-ever wrist chronograph, the historic 1964 Seiko Crown Chronograph, into a versatile contemporary form factor. It pairs a solid stainless steel case with a warm ivory dial, an open-aperture exhibition balance window at 9 o'clock, a dedicated 24-hour sub-dial at 11 o'clock, vintage sepia-toned LumiBrite geometric indices, an in-house Japanese automatic mechanical movement, a retro box-shaped Hardlex crystal, a dependable 50-meter water resistance rating, and a solid stainless steel construction. Perfectly tailored for gentlemen seeking authentic mechanical heritage, mid-century horological charm, and refined sartorial versatility, it transitions effortlessly from smart-casual weekend gatherings to tailored professional attire. The defining visual highlight of this SSA423 reference is its layered vintage dial architecture, presented in an elegant warm ivory and cream tone with subtle circular grained texturing. At the 9 o'clock position, an open-heart exhibition cutout reveals the rapid oscillations of the mechanical balance wheel and escapement, while an overlapping 24-hour indicator at 11 o'clock provides instant day\/night orientation. The dial is framed by a fixed black timing bezel with a vintage 60-minute metallic track, directly echoing the outer ring of the historic 1964 Crown Chronograph. The dial layout features faceted, polished rectangular indices and syringe-style hour and minute hands treated with Seiko’s specialized warm-toned LumiBrite compound, ensuring clear low-light readability while preserving an authentic aged patina look. A subtle inner railway minute track and faceted crystal reflections from the box-shaped Hardlex glass create dynamic light play across the dial face. The harmonic interplay between the warm ivory dial, open balance wheel, black fixed bezel, polished case bevels, and stainless steel casing delivers a distinctive, artistic, and distinguished presence on the wrist. Beneath its vintage exterior, the watch is powered by Seiko’s proven in-house Caliber 4R39 automatic mechanical movement. Built with advanced self-winding mechanical architecture, the movement is equipped with manual hand-winding capability and second-hand hacking (stop-seconds) functionality for down-to-the-second time synchronization. Operating at 21,600 vibrations per hour (3 Hz) across 24 jewels, this mechanical engine coordinates central three-hand timekeeping alongside a synchronized 24-hour sub-dial complication and an open-heart balance wheel, delivering a dependable 41-hour power reserve generated entirely by the natural motion of the wearer’s wrist or manual crown winding. The case is engineered with Seiko’s vintage-inspired Style60’s sports dress architecture, measuring 40mm in diameter with a profile thickness of 12.8mm, an ergonomic lug-to-lug distance of 47.0mm, and a 20mm lug width, providing a flush, balanced, and remarkably comfortable fit across a wide variety of wrist profiles. Dial protection is provided by a vintage-profile, box-shaped Hardlex crystal with beveled perimeter edges that produce gentle optical distortion characteristic of 1960s acrylic crystals while offering modern scratch durability. Turning the watch over reveals an exhibition see-through screw-down case back proudly displaying the rotating gold-tone rotor, decorated bridges, and mechanical gear train within. Built for dependable daily wear, the watch achieves a certified 50-meter (5 bar \/ 5 ATM \/ 165 ft) water resistance rating suitable for everyday splashes, rain, and light water contact. The timepiece comes completed on a solid stainless steel construction, featuring alternating brushed and polished links secured by a three-fold deployment clasp with twin push-button release.\u003c\/p\u003e","brand":"MonaWatch","offers":[{"title":"Default Title","offer_id":54046903992634,"sku":"SSA423J1","price":1605.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/5858\/3354\/files\/NewProject_3ac2c561-62b3-405b-8d20-53a3d9a0b8e1.webp?v=1789195126","url":"https:\/\/www.monawatch.com\/products\/seiko-presage-ssa423j1-1964-vintage-style-60s-mens-watch","provider":"MonaWatch","version":"1.0","type":"link"}
