(SERVICED) Rare Vintage 1973 Seiko 5 Actus SS Blue Dial 23 Jewels 6106-7590

Emphasizing its clean identity, the watch features a heavily recessed crown at 4 o’clock, a signature Seiko design trait that ensures an unbroken, seamless case silhouette. The standout feature of this specific 7590 reference is its unique, heavy-block applied indices with contrasting white inserts, which add a fascinating architectural depth and capture light across the dial surface with sharp precision.
