Description from the seller
SEIKO 5 SPORTS SKX “TIME SONAR” – TRANSLUCENT BLUE DIAL – AUTOMATIC – NEW – SRPJ45K1
---
DESCRIPTION
Brand-new Seiko 5 Sports SKX “Time Sonar” SRPJ45K1, an eye-catching automatic sports watch inspired by Seiko's legendary Time Sonar models from the 1970s.
This distinctive model combines the iconic SKX-inspired case design with a spectacular translucent turquoise-blue dial, allowing the underlying rotating day and date discs to remain partially visible. This unusual feature creates a fascinating mechanical effect and gives the watch a unique appearance that sets it apart from conventional Seiko 5 Sports models.
The dial features concentric detailing, prominent LumiBrite hour markers, bold luminous hands and a contrasting orange-red seconds hand. The day-date display at 3 o'clock includes a bilingual English-Spanish calendar.
The striking two-tone blue and black unidirectional rotating bezel complements the translucent dial, while the stainless steel case and matching bracelet provide the robust construction associated with Seiko's sports watches.
Inside beats the reliable Seiko calibre 4R36, a 24-jewel automatic movement offering approximately 41 hours of power reserve, manual winding and hacking seconds. The movement can be admired through the transparent exhibition caseback.
Presented in brand-new condition, complete with its original Seiko presentation box, outer packaging and original hang tag.
An excellent opportunity to acquire a distinctive modern Seiko automatic watch combining vintage-inspired aesthetics, contemporary reliability and an exceptional dial design.
