The Watch
Japanese watchmaker Seiko unveils a new timepiece from its Presage collection. Inspired by the Blue Moon cocktail, its dial captures the color of that iconic drink under the glow of a late-night lounge bar. Crafted with masterful attention to detail, it brings effortless elegance and understated sophistication to your wrist - a versatile companion for any outfit in your wardrobe. The stainless steel case measures 40.5 mm in diameter and 11.8 mm thick, sitting beautifully on the wrist. A crown at 3 o'clock lets you set the time with ease. A scratch-resistant Hardlex crystal protects the dial from everyday wear, while the screwed and transparent caseback invites watch enthusiasts to admire the movement in action.
The Dial
The standout feature of this dial is its open-heart display at 9 o'clock, offering a daily glimpse into the movement beneath. The round dial showcases a stunning blue gradient that draws the eye instantly. Its clean, uncluttered design makes room for all the elements needed for optimal readability. A finely detailed minute track runs along the outer edge, while silver-toned spade-tipped indices guide the hands for easy time reading. The silver hands mark hours and minutes with precision, while a slender gold seconds hand sweeps gracefully behind them. At 6 o'clock, "Made in Japan" is engraved as a mark of authenticity. Above it, the Presage collection name appears alongside the movement type. And at 12 o'clock, Seiko proudly signs the dial with its iconic name.
The Movement
At the heart of this Seiko model beats a Japanese automatic movement. The in-house caliber 4R38 delivers reliable precision for hours, minutes, and seconds throughout your day - and comes with a 41-hour power reserve.
The Strap
The elegance of this timepiece extends to its tonal topstitched strap. Crafted in blue leather, it harmonizes beautifully with the matching dial for a cohesive, polished look. Interchangeable pins are included so you can swap straps to suit your style. The strap fastens with a classic pin buckle.
Water Resistance
With a water resistance rating of 5 atmospheres (50 meters), this watch offers a solid entry into everyday water resistance. While it's not designed for swimming, bathing, or diving, you can comfortably wear it in the shower without worry. That said, our experts recommend keeping this timepiece dry whenever possible to preserve its mechanism for years to come.
