FAQ

Q: What is the Save The Ocean collection?

A: Seiko's Save The Ocean collection represents the brand's commitment to marine conservation and environmental stewardship. A portion of the proceeds from each Save The Ocean timepiece supports ocean preservation initiatives worldwide. This SRPF77K1 features a distinctive blue gradient dial inspired by the depths of the ocean, serving as both a beautiful design element and a reminder of our responsibility to protect marine ecosystems.



Q: What is the power reserve of the 4R36 movement, and do I need to wind it daily?

A: The Seiko calibre 4R36 automatic movement provides approximately 41 hours of power reserve when fully wound. If worn daily, the natural motion of your wrist will keep the watch running indefinitely. However, this movement also features manual winding capability via the crown, allowing you to wind it if it has stopped or to ensure a full power reserve before storing the watch overnight.



Q: Is this watch suitable for professional diving?

A: Yes, absolutely. With 200 metres (20 ATM) of water resistance, a screw-down crown, solid screw-down caseback, and a unidirectional rotating dive bezel, the SRPF77K1 meets ISO 6425 standards for professional dive watches. The luminous hands and markers ensure readability in low-light underwater conditions, whilst the sapphire crystal provides excellent scratch resistance during rigorous use.



Q: What is the purpose of the magnifier lens over the date window?

A: The magnifier lens, commonly referred to as a cyclops, enlarges the date display by approximately 2.5 times, making it significantly easier to read at a glance. This is particularly useful when wearing the watch underwater or in challenging visibility conditions, and it's a hallmark feature of many professional dive watches.



Q: Can I service this watch in South Africa?

A: Yes, as an authorised Seiko retailer, Cassim & Co. can arrange servicing through certified Seiko service centres. We recommend servicing your automatic watch every 3-5 years to maintain optimal performance and water resistance. Our team can facilitate this process and ensure your timepiece receives genuine Seiko parts and expert care throughout its lifetime.



Q: Will the blue silicone strap be comfortable for daily wear?

A: Yes, the blue silicone strap is designed for all-day comfort and durability. Silicone is hypoallergenic, resistant to saltwater and chlorine, and remains flexible in various temperatures. It's an excellent choice for an active lifestyle, and the strap can be easily cleaned with fresh water and mild soap. Should you wish to change the strap in future, the 22mm lug width accommodates a wide variety of aftermarket options.



Q: What is the difference between the King Turtle and the standard Turtle models?

A: The King Turtle features a larger 45mm case diameter compared to the standard Turtle's 42.5mm case, providing enhanced wrist presence and improved dial legibility. Both share the iconic cushion-shaped case design that has made the Turtle collection so beloved, but the King Turtle offers a more substantial wearing experience suited to those who prefer larger timepieces or have larger wrists.

Warranty

  • Warranty Period: This Seiko timepiece is covered by a 3-year international manufacturer's warranty from the date of purchase.

  • Authorised Retailer: This warranty is valid only when the watch is purchased from an authorised Seiko retailer such as Cassim & Co. Please retain your original purchase receipt as proof of purchase.

  • Coverage: The warranty covers manufacturing defects in materials and workmanship under normal use conditions. This includes defects in the movement, case, dial, hands, and other original components.

  • Exclusions: The warranty does not cover normal wear and tear, scratches, deterioration of plating or finish, battery replacement, strap or bracelet wear, broken or scratched crystals due to impact, water damage resulting from improper use or failure to ensure the crown was secured, damage caused by accidents, misuse, or unauthorised repairs or modifications.

  • Water Resistance: Water resistance is not a permanent condition and may be affected by ageing of gaskets or accidental impact. Water resistance cannot be guaranteed unless regular maintenance and gasket replacement is carried out as recommended.

  • Service Requirements: To maintain warranty coverage, any servicing or repairs must be performed by authorised Seiko service centres. Unauthorised servicing will void the warranty.

  • Warranty Claims: Should you experience any issues covered under warranty, please contact Cassim & Co. with your proof of purchase, and we will facilitate the warranty claim process with Seiko on your behalf.

  • International Validity: This warranty is valid internationally at authorised Seiko service centres worldwide, ensuring peace of mind wherever your travels take you.

Care Guide

  • Daily Wear: Avoid exposing your watch to extreme temperatures, strong magnetic fields, or harsh chemicals including solvents, detergents, and perfumes, which can damage the seals and finish.

  • Water Resistance: Although water-resistant to 200 metres, ensure the crown is fully screwed down before any water exposure. After swimming in saltwater or chlorinated pools, rinse the watch thoroughly with fresh water and dry with a soft cloth.

  • Crown Operation: Never operate the crown or bezel whilst the watch is submerged or wet. Always ensure the crown is screwed down securely after setting the time or winding the movement.

  • Strap Maintenance: Clean the silicone strap regularly with fresh water and mild soap to remove perspiration, dirt, and salt deposits. Allow it to dry completely before wearing.

  • Crystal Care: Whilst sapphire crystal is highly scratch-resistant, avoid impact with hard surfaces such as ceramic, concrete, or other sapphire crystals. Clean the crystal with a microfibre cloth to maintain clarity.

  • Automatic Movement: If the watch has stopped due to inactivity, wind it manually approximately 20-30 times clockwise before wearing to ensure adequate power reserve. Avoid vigorous shaking or rapid wrist movements to wind the movement.

  • Storage: When not wearing your watch for extended periods, store it in a cool, dry place away from direct sunlight. Consider using a watch winder if you have multiple automatic timepieces in rotation.

  • Servicing Schedule: We recommend professional servicing every 3-5 years to maintain water resistance, lubricate the movement, and ensure optimal performance. Water resistance seals deteriorate over time and should be replaced during servicing.

  • Magnetic Fields: Keep your watch away from strong magnetic sources such as speakers, mobile phones, magnetic clasps, and MRI machines, as magnetisation can affect timekeeping accuracy.

  • Impact Protection: Whilst designed for professional use, automatic movements contain delicate components. Avoid subjecting your watch to severe shocks or impacts during activities such as golf, tennis, or motocross.
