The SPB471J1 takes that concept and adds an open heart aperture at 9 o'clock, revealing the oscillating rotor of the 6R5J movement beneath. It is a watchmaker's move: using the mechanism itself as part of the aesthetic. A 24-hour subdial at 6 o'clock adds a second complication, and the dual-curved sapphire crystal completes a dial that rewards attention at every angle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy This Watch Stands Out\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOpen heart aperture at 9 o'clock — the movement visible as part of the dial design\u003c\/li\u003e\n\u003cli\u003e'Sumi-iro' black dial inspired by the depth and texture of Japanese ink\u003c\/li\u003e\n\u003cli\u003eSeiko Calibre 6R5J automatic — 72-hour power reserve, hacking and hand-winding\u003c\/li\u003e\n\u003cli\u003e24-hour subdial at 6 o'clock for a second time reference\u003c\/li\u003e\n\u003cli\u003eDual-curved sapphire crystal for optical clarity and vintage-influenced aesthetics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMovement: Seiko Calibre 6R5J, Automatic (21,600 vph), 24 jewels\u003cbr\u003ePower Reserve: 72 hours\u003cbr\u003eCase Size: 40.2 mm\u003cbr\u003eCase Material: Stainless Steel with super hard coating\u003cbr\u003eCrystal: Sapphire, dual-curved\u003cbr\u003eWater Resistance: 100 metres\u003cbr\u003eDial: Black (Sumi-iro), open heart aperture at 9 o'clock, 24-hour subdial at 6 o'clock\u003cbr\u003eBand: Stainless steel bracelet with deployment clasp\u003cbr\u003eModel Reference: SPB471J1\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIn the Box\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSeiko Presage watch (SPB471J1), original Seiko box, warranty card, instruction manual.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuthenticity \u0026amp; Shipping\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEvery watch at Ganga Ram's Watch Gallery is 100% genuine, sourced through authorised Seiko India channels.
