Dial

The logo symbolizing the "DATSUN" is placed at the 6 o'clock position. Inspired by the color of rally cars, which minimizes light reflection, matte black is used for the dial, while red accents are added to the second hand and dial ring to enhance legibility.
The Arabic numerals on the dial ring take inspiration from the font used on the Datsun 240Z dashboard.

Case / Strap

By operating the 4 o'clock crown, a countdown timer function can be used to measure key intervals in motorsports competitions, such as the time remaining before the start and target durations for tasks such as tire changes and refueling.
The leather strap is sourced from tanneries certified by the Leather Working Group, of which Seiko is a member. The seams on the inner sides of both of the leather strap is covered with lining to minimize damage from sweat and water.

*The Leather Working Group (LWG) is a non-profit organization dedicated to responsible and sustainable leather production. Seiko is a member of LWG and aims to increase the percentage of leather produced by LWG-certified tanneries to over 90% in the future.

Case Back

The iconic mark, a symbol of the "DATSUN", is engraved on the case back.
The words "LIMITED EDITION" and the serial number are applied on the case back.
