How is Grand Seiko different from Seiko?
Grand Seiko is Seiko’s luxury watch division, produced to a much higher standard than standard Seiko models. Grand Seiko watches feature superior finishing, tighter tolerances, and advanced movement technology, and are treated as high-end horological pieces rather than mass-market watches.
Spring Drive is a unique Grand Seiko movement that combines a traditional mechanical mainspring with an electronic regulator, resulting in exceptional accuracy and the signature smooth sweeping seconds hand. This technology is exclusive to Seiko and Grand Seiko and requires specialist knowledge to service correctly.
Yes. Despite their electronic regulation, Spring Drive movements are still mechanically powered and require professional servicing. This includes inspection of the gear train, lubrication, and regulation of the electronic control system to maintain performance.
Yes. In addition to Spring Drive, Grand Seiko produces high-end mechanical and quartz movements, including the highly accurate 9F quartz calibre. We service all Grand Seiko movement types using appropriate tools and techniques.
Common issues include reduced accuracy due to ageing lubricants on mechanical models, power reserve issues on Spring Drive watches, crown or stem wear, and seal degradation affecting water resistance if the watch has not been serviced regularly.
Service intervals vary by movement type, but most Grand Seiko watches benefit from periodic servicing every few years to maintain accuracy, longevity, and water resistance. Each watch is assessed individually to determine the most appropriate service plan.
Absolutely. Grand Seiko watches are high-precision luxury timepieces with significant horological and financial value. Professional servicing helps preserve accuracy, craftsmanship, and long-term value.
