Presage Classic Open Heart SPB471J1 Watch

The Watch

Proud of its watchmaking heritage and over a century of innovation, Seiko continues to push the boundaries with timepieces that integrate the latest technology. Every collection is the result of precision engineering and meticulous craftsmanship, guaranteeing unmatched accuracy and reliability. Meet the Presage SPB471J1 watch - a perfect marriage of superior Japanese artistry and timeless, elegant design. It is presented in a round case crafted from stainless steel with a curved profile for unrivaled wrist comfort. Beautifully finished, it is enhanced by a scratch-resistant coating and a flawless alternation of polished and brushed finishes that add a sophisticated edge. Sized to suit all wrists, the case measures 40.20 mm in diameter and 13 mm in thickness. It is topped by a domed sapphire crystal that mirrors the dome-shaped dial beneath. With an anti-reflective treatment, it promises optimal legibility and superior scratch protection. At 3 o'clock, the knurled, signed crown handles the setting of hours and minutes. The case back is sealed with a screwed, transparent case back that invites you to admire the movement's complexity and beauty - while ensuring 10 ATM water resistance.

The Dial

The dial draws inspiration from the fluid softness of traditional silk - a material deeply woven into Japanese culture. Black in color, it commands attention and is elevated by an impeccable sunray finish. The outer edge features a minutes railroad track with bold markers at every 5-minute interval. The dial is adorned with baton indices - doubled at 12 o'clock - whose gray hue echoes the "alpha" hands and slender seconds hand, creating a cohesive, harmonious design. At 6 o'clock, a recessed sub-dial displays the 24-hour indication. For a more dynamic feel, a open heart aperture sits at 9 o'clock, offering a mesmerizing view of the beautifully crafted movement beneath. The finishing touches are the brand's signature elegantly displayed at 12 o'clock, and the mentions "Presage," "Automatic," and "3 Days" at 3 o'clock.

The Movement

The heart of this timepiece beats with a Japanese-made automatic movement delivering an impressive 72-hour power reserve. This is the 6R5J caliber, based on the Seiko 6R55, fitted with 24 jewels. It oscillates at a frequency of 21,600 vph and runs at an accuracy of +25/-15 seconds per day - a benchmark of reliability that drives all central functions with outstanding efficiency.

The Strap

This watch is paired with an elegant bracelet inspired by the 1970s. Crafted from stainless steel, it sits comfortably on the wrist and is enhanced by a scratch-resistant coating. For a premium look, it features alternating polished and brushed finishes that bring out its silver tone beautifully. Measuring 20 mm at the lug width, this bracelet is made up of 7 rows of links for a perfect fit and all-day wearing comfort. It fastens with a deployant clasp with push-button release for a secure hold.

Water Resistance

This model offers water resistance of 10 atmospheres, equivalent to 100 meters. Yes - this one gets wet. Ready to dive into everyday aquatic adventures, from puddles to the pool, this timepiece handles swimming without breaking a sweat. Shower, bath, and lap swimming are all fair game. That said, our Ocarat watch experts are clear: this water-resistant model is not suited for diving (recreational or professional) and should be kept away from high-pressure cleaning equipment. We also recommend keeping the crown and pushers out of reach while submerged.
