Seiko Time Sonar

"Time Sonar" from the 1970s. A unique feature is the calendar disc visible through the translucent dial.

 HUF was founded in 2002 by professional skateboarder Keith Hufnagel as a lifestyle brand that embraces the spirit of skateboarding and street culture.

 This HUF-customized watch features a case taken from the Seiko 5 Sports "Field" series. The translucent dial is adorned in "HUF" green. This color was personally selected by HUF founder Hufnagel as the brand's signature color, and it also symbolizes the HUF philosophy. The case back is also in this vibrant HUF green, and the HUF logo at 6 o'clock on the dial and on the case back further emphasize the specialness of this collaboration.

The case back is not only colored in HUF green, but also features a line drawing of the San Francisco city pattern. The words "LIMITED EDITION" and a serial number are engraved around the outside, indicating that this is a limited edition model.

 A nice feature for buyers is that the watch comes with a special box and an original watch cloth. The watch is housed in a special stainless steel box with a message from Seiko and HUF, "Make the most of your time," printed on the back. The watch cloth features a popular HUF design.
