This is a Seiko 5 DX, reference 6106-8131, produced in 1969, representing one of Seiko’s higher-grade everyday automatic watches from the late 1960s. The Seiko 5 DX series was positioned above standard Seiko 5 models, featuring improved finishing, a more robust automatic movement, and a refined case design. This model is powered by the caliber 6106 automatic movement with 25 jewels, known for its durability and practical day-date function. A notable design feature of this watch is the offset (diagonal) crown positioned around the 4 o’clock area. This angled crown layout enhances wearing comfort while maintaining a clean and balanced dial appearance, a characteristic detail seen in many late-1960s Seiko designs. The dial is a clean silver tone with applied indices, displaying a classic and understated aesthetic typical of Seiko’s domestic models from this era. The day-date window shows English day display, with date quick-set operation by pressing the crown. The day is adjusted by rotating the hands. The stainless steel case has been cleaned and retains its original sharp lines, reflecting Seiko’s functional yet elegant design philosophy of the period. The watch is fitted with a new leather strap, making it ready for immediate wear. Running at the time of listing. As a vintage watch, stable operation, accuracy, and water resistance are not guaranteed. The watch will be carefully packed and shipped with tracking for safe delivery.
