The Seiko SPB143 honors the original 1965 model, famed for its groundbreaking 150-meter water resistance. The charcoal dial framed by a unidirectional rotating bezel offers exceptional legibility. Crafted with a thinner, sleeker case for enhanced wrist comfort, this reinterpretation exudes a blend of vintage charm and modern sophistication.

The upgraded 6R35 24-jewel automatic movement, beats at 21,600 vibrations per hour with a substantial 70-hour power reserve. Constructed from stainless steel with a super-hard coating, makes this a perfect choice for every day wear. Its dual-curved anti-reflective sapphire crystal enhances visibility while guaranteeing resilience. The screw down crown and case back provide water resistance up to 200 meters, ideal for scuba diving enthusiasts. LumiBrite hands and markers ensure impeccable visibility in low-light environments. The tri-fold push button release clasp with a secure lock and extension ensures the watch remains comfortably and securely fastened during activity.
