The 56KS series was the only King Seiko line to be produce by Suwa Seikosha rather than Daini Seikosha. Suwa Seikosha and Daini Seikosha were the two segments of Seiko competing against each other in the high-end watch segment. Suwa Seikosha developed and produced Grand Seiko while Daini Seikosha developed and produced King Seiko. The 56KS watches are the only King Seikos to be produced by the Grand Seiko factory. Notice the Suwa typhoon symbol on the dial just below the words "hi-beat." This differs from the thunderbolt symbol that denotes Daini production.

A NOTE ON TARIFFS
Importing items into the US has become more expensive in 2025. On August 29th, the US is ending the "de minimis" rule which allowed shipments under $800 to enter the US without tariffs. Those goods will now be assessed a tariff based on their Country Of Origin. Our items are located in the US. There are NO TARIFFS on any of our items when shipped to a US address. When comparing our our offerings to other sellers outside the US, the final price of those items outside the US will be higher. Buyers will incur tariff and clearance fees on their purchases. Some sellers disclose those fees while others only state that the fees will be incurred. For items originally from the EU, Germany, France, Italy, UK and Japan, the tariff is 15%. For items from Switzerland, the tariff is 39%. Clearance and brokerage fees will increase the cost beyond those tariffs. Items are assessed tariffs base on "Country Of Origin" not based on the country from which they are shipped. For example, a Swiss watch shipped from Japan will incur tariffs at the Swiss rate of 39%.
