Description

The Seiko Presage Style60's SSA425J1 draws on the collection's 1960s-inspired design language, pairing a 4R39 automatic movement with a 40.8mm round case, a black dial with an open heart aperture, and a stainless steel bracelet.

Case & crystal

The round case is stainless steel and measures 40.8mm across, with a thickness of 12.8mm. The bracelet is also stainless steel, so case and band match. A Hardlex crystal protects the dial. A black rotating bezel carries rose-gold-tone minute numerals and markers, which add a warm accent against the black of the dial.

Dial

The black dial carries applied hour markers, with lume on the hands and markers for low-light reading. A 24-hour subdial sits at 12 o'clock, while an open heart aperture at 7 o'clock exposes part of the movement beneath the dial.

Movement

Inside is Seiko's automatic calibre 4R39, wound by the motion of the wrist. It provides a power reserve of 41 hours, so the watch keeps running over a typical weekend off the wrist. The open heart complication lets you watch the balance at work.

Bracelet & fit

The stainless steel bracelet closes with a three-fold clasp with push button release, which holds the bracelet securely and opens with a single press. Browse more Seiko watches or compare all watches in the range if you are weighing up sizes.

On the wrist

At 40.8mm with a 12.8mm case profile, this is a mid-sized men's watch with solid wrist presence that is not oversized. It suits average to larger wrists and works as an everyday watch, while the black dial and steel bracelet also sit comfortably with business dress. Regular servicing keeps an automatic movement running well, and our team can assist with watch servicing and repairs.

Water resistance

The watch is water resistant to 50 metres. In plain terms, it copes with splashes, rain and hand washing, but it is not intended for swimming or diving.

Warranty

Supplied with the 3-year international Seiko warranty, valid when purchased from an authorised retailer and registered at purchase through Cassims & Co. The warranty covers manufacturing defects in materials and workmanship; it does not cover normal wear, batteries, straps, glass, or damage from misuse or water ingress through an unscrewed crown.

Our watch service centre in Johannesburg handles warranty work, batteries, bracelet sizing and servicing.

Care guide
  • Wipe the stainless steel case and bracelet with a soft, slightly damp cloth, then dry them thoroughly.
  • Keep the watch away from soaking and swimming: the 50 metre water resistance suits splashes and rain only.
  • If the watch has stopped after sitting unworn beyond its 41-hour power reserve, wind it by gently rocking it or wearing it, then reset the time.
  • Avoid knocks to the Hardlex crystal and the open heart aperture area.
  • Have the automatic movement serviced at regular intervals so the 4R39 keeps running accurately.
