Over the course of its history, Seiko has brought numerous innovations to the market. Some of the most prominent include one of the first automatic chronographs in the world, the highly-efficient magic lever system, and the hybrid Spring Drive movement, in which a quartz crystal replaces the traditional lever escapement. These pioneering innovations are featured in the Grand Seiko luxury watch collection. The Tokyo-based manufacturer introduced this flagship collection in 1960, and it remains home to some of the best mechanical wristwatches in the world. Only a few Grand Seiko watches are produced each year. The designs are streamlined, elegant, and yet radiate a sense of sportiness. Today you can purchase a pre-owned, self-winding Grand Seiko for approximately 3,500 euros. Unworn models start at 4,900 euros.

The horological masterpieces found in the Credor series are true examples of haute horologerie. This collection proves that highly complicated watches with a minute repeater or tourbillon are also made in Japan.

In addition to luxury watches, Seiko has many quartz watches in its catalog. They were the first manufacturer in the world to make battery-powered wristwatches, starting at the end of 1969. The Quartz Astron's deviation was only about one minute per year — a significant achievement at the time. Today, watches in the Astron collection are high-tech timepieces with a GPS module and solar cells, which charge the integrated battery using light. The quartz movement automatically sets the time via the GPS receiver and, therefore, never deviates from the current local time. The newest wristwatches in this Seiko collection take 40 time zones into account and also have a perpetual calendar that won't need to be adjusted until February 28, 2100.
