The Seiko 5 Sports GMT SSK035K1 is a purpose-built tool watch that brings true dual-time capability to the legendary Seiko 5 Sports lineage. Powered by the robust 4R34 automatic GMT movement, this 42.5mm stainless steel diver's watch features a striking green sunburst dial, complemented by a bidirectional green and black bezel. The GMT complication, displayed via a contrasting yellow 24-hour hand, allows simultaneous tracking of two time zones—an essential function for the modern traveller or anyone managing international schedules.
The dial layout is unmistakably Seiko: applied indices with generous LumiBrite coating, a date window at 3 o'clock with magnifying cyclops lens, and the signature day-date complication at 12 o'clock. The stainless steel Jubilee-style bracelet provides exceptional comfort and period-correct styling, while the screw-down crown and case back ensure water resistance suitable for recreational diving. At Cassim & Co., we are proud to offer this exceptional timepiece as an authorised Seiko retailer, ensuring full manufacturer warranty protection and after-sales confidence.
The Calibre 4R34 at the heart of this watch represents Seiko's dedication to accessible mechanical horology. With 24 jewels, a 41-hour power reserve, and both automatic winding and manual winding capability, this movement delivers reliable performance day after day. The bi-directional rotating bezel, while not a traditional dive bezel, offers timing functionality and adds visual drama to the design. This watch is part of our curated selection of SEIKO watches, each chosen for its blend of functionality, heritage, and value.
Whether you're tracking home time during international business travel, coordinating with colleagues across continents, or simply appreciating the mechanical elegance of a true GMT complication, the SSK035K1 delivers. The green dial variant—often affectionately nicknamed the 'Sprite' in collector circles—offers a fresh alternative to traditional dive watch aesthetics. Visit us at our Mall of the South boutique to experience this watch in person, and discover why Seiko's 5 Sports GMT collection has earned such devoted following among enthusiasts. Our watch servicing and repairs team is always on hand to ensure your Seiko performs flawlessly for years to come.

FAQ
Q: What is a GMT watch and how do I use the GMT function on this Seiko?
A: A GMT watch displays a second time zone simultaneously. The SSK035K1 features a 24-hour hand (the yellow arrow hand) that rotates once every 24 hours. To use it, first set your local time normally. Then rotate the bidirectional bezel so that the 24-hour hand aligns with the correct hour in your second time zone. The bezel markings (0-24) allow you to track a second time zone at a glance—perfect for international business or travel.
Q: Is this watch suitable for swimming and diving?
A: Yes. With 100 metres of water resistance and a screw-down crown, the SSK035K1 is suitable for recreational swimming, snorkelling, and light water sports. While it has diving aesthetics and adequate water resistance for shallow diving, serious dive watch enthusiasts may prefer Seiko's Prospex range with 200m+ ratings and ISO certification. Always ensure the crown is screwed down before water exposure.
Q: Does this watch require batteries?
A: No. The SSK035K1 is powered by the automatic Calibre 4R34 movement, which winds itself through the natural motion of your wrist. It also features manual winding capability—simply unscrew the crown and wind clockwise to provide initial charge or top up the power reserve. With regular wear, the watch maintains a 41-hour power reserve.
Q: Can the bracelet be adjusted to fit my wrist?
A: Absolutely. The stainless steel bracelet features removable links for precise sizing. Our experienced team at Cassim & Co. will professionally size the bracelet to your wrist at no additional charge when you purchase the watch. We can also assist with future adjustments or link replacements as needed.
Q: What is the difference between the 4R34 and standard Seiko movements?
A: The Calibre 4R34 is Seiko's GMT-equipped movement, adding a dedicated 24-hour hand and internal mechanism to track a second time zone. It's based on the reliable 4R36 architecture but includes the complication necessary for dual-time display. This movement also features hacking seconds (the second hand stops when you pull the crown out, allowing precise time setting) and manual winding capability.
Q: Why is the bezel bidirectional rather than unidirectional like most dive watches?
A: The bidirectional rotating bezel on this model is designed specifically for GMT functionality rather than dive timing. It allows you to set and adjust the 24-hour reference for your second time zone quickly. While Seiko's dedicated dive watches feature unidirectional bezels for safety, the 5 Sports GMT prioritises travel functionality and ease of use for dual-time tracking.
Q: Does this watch come with the full Seiko international warranty?
A: Yes. As an authorised Seiko retailer, Cassim & Co. provides the full 3-year international Seiko warranty with every watch. This warranty covers manufacturing defects in materials and workmanship. Your warranty card will be completed and stamped at the time of purchase, and we provide full after-sales support throughout the warranty period and beyond.

Care Guide
- Daily Wear: Avoid exposing your watch to extreme temperatures, strong magnetic fields, or severe impacts that could affect movement accuracy or damage the case.
- Water Resistance: Always ensure the screw-down crown is fully tightened before any water exposure. Do not operate the crown or rotate the bezel while the watch is wet or submerged.
- Cleaning: Clean the stainless steel case and bracelet regularly with a soft cloth. For deeper cleaning, use warm soapy water and a soft brush, ensuring the crown is screwed down. Rinse with fresh water after saltwater exposure and dry thoroughly.
- Power Reserve: If the watch stops due to insufficient power reserve, manually wind it by unscrewing the crown and rotating clockwise approximately 20-30 times. Wear the watch regularly to maintain automatic winding.
- Accuracy: The Calibre 4R34 maintains accuracy within -35 to +45 seconds per day when worn regularly. Accuracy can be affected by wearing position, temperature, and how fully wound the mainspring is.
- Bracelet Maintenance: Periodically check bracelet pins and clasp for security. The bracelet may accumulate dirt and skin oils between links—clean regularly to maintain appearance and comfort.
- Storage: When not wearing your watch, store it in a cool, dry place away from magnetic devices. If storing long-term, wind the watch periodically to keep the movement lubricated.
- Servicing: We recommend a complete movement service every 5-7 years to maintain optimal performance. Cassim & Co. can arrange authorised Seiko servicing to preserve your warranty and ensure genuine parts are used.
- Bezel Care: The bidirectional bezel should rotate smoothly with moderate resistance. If rotation becomes stiff or gritty, bring the watch in for inspection—sand or debris may have entered the bezel mechanism.
