About the Grand Seiko Heritage Collection

The Grand Seiko Heritage Collection pays homage to the brand's storied past, embodying the timeless elegance and meticulous craftsmanship that have defined Grand Seiko since their inception in 1960. This collection draws inspiration from iconic models and design principles that have shaped the brand's identity over the decades. It seamlessly integrates historical elements with modern watchmaking techniques, offering a bridge between Grand Seiko's rich legacy and their innovative future. The Heritage Collection is a celebration of classic design, precision, and enduring beauty, catering to watch enthusiasts who appreciate both tradition and technological advancement.


The design aesthetic of the Grand Seiko Heritage Collection is characterised by its adherence to the fundamental principles of Japanese artistry and precision. The collection features a variety of case materials, including stainless steel, titanium, and precious metals like 18k gold, all crafted with the brand's signature Zaratsu polishing technique. This method ensures a distortion-free, mirror-like finish, enhancing the watch's visual appeal. The dials are meticulously detailed, often showcasing textures inspired by nature, such as the iconic snowflake pattern or the deep blue of the sky. The hands and markers are designed for optimal legibility, featuring sharp, polished edges that reflect light beautifully. The overall design is understated yet elegant.


The Grand Seiko Heritage Collection includes a variety of timepieces, featuring models powered by mechanical, Spring Drive, and quartz movements. The collection offers a range of options, from simple time-only watches with a date function to functional GMT ones. It also includes large 40mm watches, delicate 30mm ones, and more decorated gem-set pieces, catering to the preferences of all Grand Seiko patrons.

Mechanical Hi-Beat 36000 GMT 44GS 55th Anniversary Limited Edition


Calibre 9S86 belongs to Grand Seiko's illustrious family of Hi-beat 36000 movements that have created an undisputable mechanical hegemony in the industry by providing accuracy and precision even higher than the recognised Swiss chronometer standards. 9S86 was introduced in 2014 with the GPHG winner of the “Petit Aiguille” award, the Grand Seiko Hi-Beat 36000 GMT. 

It is built on the hi-beat calibre 9S85, retaining all its features with the addition of a 24-hour GMT hand and an independently adjustable hour hand. Seiko's patented alloy Spron 610 is used in the balance springs to enhance resistance to magnetism and shock. The escapement wheel and pallet fork are crafted using MEMS (Micro Electro Mechanical Systems) technology, improving precision and durability. As a result, the watch maintains an accuracy of +8/-1 seconds per day under normal conditions and a power reserve of 55 hours with a single barrel.
