Seiko expands its Presage Sharp Edged Series by launching two open heart models with three days of power reserve.
Introduced in 2020, the Seiko Presage Sharp Edged Series stands out its angular silhouette, distinctively patterned dial, and hands and indexes that reflect light while enhancing legibility. Now, the brand presents two new models with a three-day automatic movement and enhanced design features.
Beating at 21,600 vph, the new automatic Caliber 6R5J boasts an increased power reserve of three days (72 hours) when fully wound. It displays the hour, the minute, and the seconds, as well as a 24-hour sub-dial at 6 o’clock.
The dial opening at 9 o’clock shows the signature asanoha, or “hemp-leaf” pattern, which matches the same pattern seen on the dial surface. The movement’s escapement can be admired through this opening. Indicating the 72 hour power reserve, the dial features the inscription “Automatic 3 Days” below the SEIKO and PRESAGE names.
Equipped with a gold-colored oscillating weight, the Seiko Caliber 6R5J is also visible through an exhibition case back.
This Sharp Edged Series comes with a new design. A dual-curved sapphire crystal makes its first appearance in the Sharp Edged Series, giving a slender look on the wrist. The new crystal also enhances legibility.
An additional mirror-finished facet between the top and side surfaces of the case adds an extra sparkle to the design.
The dial highlights the traditional asanoha pattern, a distinctive motif that has appeared on Japanese textiles since the Heian period over 1,000 years ago.
The new Open-heart watch is available in two dial versions with traditional Japanese colors. The light one (SPB415J1) is called shironeri and is reminiscent of unbleached white silk, and the dark dial (SPB417J1) is aitetsu, or indigo iron.
The hour markers and seconds hand feature new designs. The markers are sharper and point toward the center of the dial. Gently curved down toward the markers, the seconds hand has a more pronounced and angular counterweight with a spiked tail.
The new Presage Sharp Edged Series Open Heart watches will be available starting in June 2023 at the Seiko Boutiques and select retail partners worldwide.
