This timepiece is a prime example of Seiko's design daring in the 1970s! The Seiko Advan line was created exclusively for the Japanese Domestic Market (JDM) to showcase futuristic design paired with reliable mechanical movements. The immediate selling point is that incredible, deep blue "Woven Basket" or "Tapestry" dial. This highly textured, two-dimensional pattern makes the dial appear to shift and shimmer in the light, a complex visual effect that instantly elevates the watch into a high-art piece.
Powering this beauty is the Caliber 7039, a robust 21-Jewel automatic movement produced by the Daini factory. This caliber is a reliable workhorse and features the desirable quick-set day and date function, which operates through the crown. The quick-set day is particularly cool as it displays the day in both English and Kanji, a signature detail of its JDM origin that connects the wearer to the watch's Japanese heritage.
The stainless steel case boasts a bold, tonneau-like profile with wide, flat surfaces and sharp facets—the iconic "Space Age" aesthetic of the time. The overall presence of the piece, with its intricate dial texture and clean markers, delivers immense visual depth. This is a must-have for the collector who appreciates mechanical quality married to the most audacious and unique dial designs of the 20th century.
