The Seiko 5 Sports SRPD51K1 is a modern interpretation of classic dive watch design, combining Seiko's legendary automatic movement reliability with contemporary sports styling. This automatic diver features a striking deep blue sunray dial that shifts beautifully in changing light, protected by a robust stainless steel case measuring 42.5mm in diameter. The coin-edge bezel, luminous markers, and day-date complication at 3 o'clock deliver both functionality and vintage-inspired charm.

At the heart of this timepiece beats Seiko's dependable Calibre 4R36 automatic movement, built entirely in-house with 24 jewels and offering approximately 41 hours of power reserve. This self-winding mechanism also features manual winding capability, giving you the flexibility to top up the power reserve when needed. Water-resistant to 100 metres, the SRPD51K1 is ready for swimming, snorkelling, and everyday adventure.

As an authorised retailer of SEIKO watches, Cassim & Co. guarantees the authenticity of every timepiece we sell, backed by Seiko's full 3-year international warranty. The stainless steel bracelet features a secure fold-over clasp with push-button release, and the LumiBrite coating on hands and markers ensures legibility in low-light conditions.

Whether you're a dedicated collector of Japanese horology or seeking your first serious automatic watch, the Seiko 5 Sports SRPD51K1 offers exceptional value and proven performance. Our watch servicing and repairs team is available for future maintenance needs, and we invite you to experience this timepiece in person at our Mall of the South boutique in Johannesburg, where our specialists can assist with sizing and answer any technical questions.

FAQ

Q: Does this watch require batteries?

A: No, the SRPD51K1 is powered by Seiko's 4R36 automatic movement, which winds itself through the natural motion of your wrist. It also features manual winding capability via the crown, so you can wind it when not wearing it regularly.

Q: What is the power reserve, and what happens if I don't wear it for a few days?

A: The movement provides approximately 41 hours of power reserve when fully wound. If you don't wear the watch for longer than this period, it will stop and will need to be manually wound and the time reset before wearing again.

Q: Can I swim and shower with this watch?

A: Yes, with 100 metres of water resistance, this watch is suitable for swimming, snorkelling, and showering. However, the crown must be fully pushed in and secured. We do not recommend operating the crown or buttons while the watch is wet or submerged.

Q: How do I adjust the day-date complication?

A: Pull the crown out to the first position and rotate to adjust the date. Pull it to the second position to set the time, which will also advance the day. Avoid adjusting the date between 9pm and 3am, as the mechanism is engaged during this period and adjustment may cause damage.

Q: Is this watch suitable for diving?

A: While this watch has dive-inspired styling and 100-metre water resistance suitable for recreational swimming and snorkelling, serious scuba diving typically requires a minimum of 200 metres water resistance. This model is best suited for everyday water activities rather than professional diving.

Q: How often does an automatic watch need servicing?

A: We recommend servicing your Seiko automatic watch every 3 to 5 years to ensure optimal performance and longevity. Our servicing team at Cassim & Co. can assist with regular maintenance, cleaning, and movement regulation.

Q: Can the bracelet be adjusted to fit my wrist?

A: Yes, the stainless steel bracelet can be professionally sized to fit your wrist perfectly. This complimentary service is available when you purchase the watch from our Mall of the South boutique, or you can visit us anytime for adjustments.

Warranty
  • Warranty Period: This Seiko watch is covered by a 3-year international manufacturer's warranty from the date of purchase when purchased from an authorised retailer.
  • What Is Covered: The warranty covers manufacturing defects in materials and workmanship under normal use conditions.
  • What Is Not Covered: The warranty does not cover normal wear and tear, battery replacement (not applicable to automatic models), strap or bracelet wear, crystal scratches, cosmetic damage, or damage resulting from accidents, misuse, or unauthorised repairs.
  • Water Damage: Water damage resulting from improper use (such as operating the crown while submerged or exceeding the stated water resistance) is not covered under warranty.
  • Authorised Retailer Requirement: The warranty is valid only when the watch is purchased from an authorised Seiko retailer such as Cassim & Co. Proof of purchase is required for all warranty claims.
  • Service Network: Warranty service is available through Seiko's authorised service network. Contact Cassim & Co. for assistance with warranty claims and service arrangements.
Care Guide
  • Regular Wear: Automatic watches perform best with regular wear. If not worn daily, manually wind the watch approximately 40 times via the crown to maintain power reserve.
  • Water Resistance: Ensure the crown is fully pushed in and never pull out the crown or operate pushers while the watch is wet or submerged. Rinse with fresh water after exposure to salt water or chlorine.
  • Cleaning: Wipe the case and bracelet regularly with a soft, lint-free cloth. For deeper cleaning of the stainless steel bracelet, use warm soapy water and a soft brush, then dry thoroughly.
  • Magnetic Fields: Avoid placing your watch near strong magnetic sources such as speakers, mobile phones, or magnetic clasps, as this may affect timekeeping accuracy.
  • Impacts: While built for sports use, avoid severe impacts or dropping the watch, as this may damage the movement or crystal.
  • Storage: When not in use, store your watch in a cool, dry place away from direct sunlight. Consider using a watch winder if you have multiple automatic watches in rotation.
  • Date Adjustment: Never adjust the date or day between 9pm and 3am when the calendar mechanism is automatically engaged, as this may damage the movement.
  • Professional Servicing: Have your watch professionally serviced every 3 to 5 years to maintain water resistance seals, lubricate the movement, and ensure optimal performance.
