The Vibrant Spirit of the Grasshopper

Inspired by the refreshing green 'Grasshopper' cocktail found in Tokyo’s upscale Ginza bar scene, the Seiko Presage SSA441J1 is a standout piece in the Cocktail Time collection. This model specifically celebrates the mechanical artistry of watchmaking, featuring a distinctive "open heart" window that invites you to witness the pulse of the movement.

Artistic Depth and Color

• Emerald Sunray Dial: The deep, vibrant green dial is finished with a stunning sunray texture, designed to mimic the brilliant color and clarity of its cocktail namesake.

• Open Heart Window: Located at the 9 o’clock position, the circular cutout offers a captivating view of the balance wheel, the "beating heart" of the automatic calibre.

• Vintage-Inspired Crystal: The dual-curved box-shaped Hardlex crystal creates a classic distortion at the edges of the dial, adding a sophisticated 1960s bar-aesthetic feel while maintaining excellent legibility.

Exquisite Mechanical Craftsmanship

Underneath the elegant exterior is the Seiko in-house Calibre 4R38. Designed for those who appreciate the mechanics of time, this caliber is specifically engineered for open-heart displays, omitting the date window to ensure a clean, balanced, and purely mechanical aesthetic.
