To keep any watch in use for years to come, regular inspections and servicing are essential.
King Seiko is committed to after-sales service to ensure that its watches remain cherished items for years to come.
These are some of the methods used to maintain King Seiko watches.
King Seiko provides movement repairs and overhauls for issues such as a stopped or slow-running watch, as well as light polishing.
Light polishing is a service that refines the surfaces of the case and bracelet, restoring their shine.
When light polishing is performed together with a movement repair or overhaul, it is referred to as King Seiko’s Complete Service.
※The Complete Service is available only in select regions.
※Customers may choose whether or not to include light polishing when requesting a repair.
※Light polishing is not performed as part of complimentary repairs under warranty.
※King Seiko models released prior to 2022, as well as models SJE083 and SJE087, are excluded from the Complete Service.




King Seiko’s brand philosophy, "The Newest Classic," expresses our commitment to reviving the appeal first introduced in 1961 through modern techniques, thereby offering renewed value.
To ensure that King Seiko watches are cherished for generations and retain their timeless appeal, our cases are designed to be disassembled for light polishing.
King Seiko is the only Seiko brand to offer the Complete Service.
Below, we outline each step of the process.
Upon receiving the watch, we review the customer’s request, previous repair history, and check for any scratches or stains.
We also test the hands’ movement, the calendar functions, and other operations to identify any malfunctions or irregularities.
Through these steps, we assess the overall condition of the watch.

The watch is carefully disassembled to inspect the movement and internal parts that cannot be seen from the outside.
We identify any issues, such as the watch stopping or running slow, and perform the necessary adjustments or repairs to restore proper function.

In this stage, light polishing is performed on the exterior.
The case is given a mirror finish through buff polishing to bring out its shine, along with fine hairline finishing where appropriate.
Detailed polishing in delicate areas – essential for refining the surface and restoring its luster – is carefully carried out by skilled artisans using precision hand tools.
The bracelet is polished by hand using a specialized flap wheel, a tool designed for fine polishing.
Precise hairline finishing is applied manually to each link.

When comparing the watch before and after light polishing, one can clearly see the beautifully restored mirror finish and refined hairline finish.
Light polishing smooths the surface and restores each watch’s elegant shine.

Light polishing is a service that smooths the surface and restores its shine.
The final finish may vary depending on the shape of the case or bracelet and the presence of scratches or dents.
Some marks or deeper scratches may not be completely removed.
※Please note that the crown, buttons, and case back are not subject to light polishing.
For bracelets, only the front side (excluding the logo area) is polished.
After light polishing is completed, the watch is reassembled. We then perform precise inspections, including regulating the movement for accurate timekeeping and verifying the power reserve, to ensure the watch functions perfectly.

Comprehensive water resistance tests are conducted, including air pressure testing and submerged water pressure testing. Each step ensures the watch’s functionality without compromise.

After all the processes are completed, the watch undergoes a final visual and functional inspection. Once everything has been thoroughly checked, the Complete Service is finished, and the watch is returned to the customer.

When your King Seiko returns to you, it will surely inspire an even greater sense of attachment.
The Complete Service embodies the King Seiko brand’s commitment to timeless appeal and ensures that our watches can be cherished across generations.
We carry out each step of the after-sales service process with the utmost care and dedication to help you enjoy your King Seiko for years to come.
