Grand Seiko reaches new heights with a Special Edition
Hi-Beat 36,000 creation.

Re-defining the ‘ideal’ watch

Half a century ago, the legend of Grand Seiko was born with the simple idea of creating the ideal watch. Each Grand Seiko watch should be as accurate, as legible, as durable and as easy to wear as humanly possible. Nothing more and nothing less. For more than 50 years, the Grand Seiko’s watchmakers have selected the very finest materials, designed and manufactured cutting edge movements and used traditional craftsmanship to create by hand, watches that are, in their simple sophistication, perfect expressions of all that is essential in a wrist watch. Today, the performance of Grand Seiko reaches a new height of perfection in a new Special Edition Hi-beat 36,000 timepiece. This masterpiece is the ultimate expression of the Grand Seiko ideal.

A new standard in mechanical watchmaking

The first Grand Seiko standard was set in 1966, since which time it has been raised as new materials, technologies and mainstream techniques have made possible new advances. Today, the Special Edition Hi-beat 36,000 goes beyond the standard with levels of accuracy that are among the highest in the world.

In recognition of its importance in the pantheon of Grand Seiko creations, this specially adjusted caliber is offered exclusively in 18k gold, with the lion emblem, also in gold, on the oscillating weight. Seiko’s latest hi-beat movement was introduced in 2009 and was made possible by advances in every aspect of the caliber. A new Spron material is used for the mainspring to deliver more torque and a new pallet and wheel increase the efficiency of the escapement. Together, these advances deliver more stable accuracy and a remarkable, industry-leading 55 hour power reserve. The new Special Edition builds on these advances to deliver enhanced precision as well as outstanding power reserve. On all the precision criteria, this specially tuned new piece exceeds the Grand Seiko standard. The enhanced performance of the new Special Edition is entirely the result of the skills of the Master Watchmakers at the Shizukuishi Watch Studio where the watch is created. The adjustment is entrusted to only the very best of the Studio’s most experienced watchmakers who test and select the balance springs individually.
