The Fossil Blue GMT (FS5991) is a robust dive-inspired timepiece engineered for adventurers who demand functionality without sacrificing style. Housed in a substantial 46mm stainless steel case, this quartz-powered watch features a striking blue sunray dial adorned with luminous applied indices and Mercedes-style hands, ensuring legibility in low-light conditions. The unidirectional rotating bezel with its blue and black 24-hour GMT insert allows simultaneous tracking of a second time zone—an essential complication for frequent travellers or those who maintain international connections.
Water-resistant to 10 ATM (100 metres), this timepiece is built to withstand swimming and recreational diving, while the hardened mineral crystal lens protects the dial from scratches during daily wear. The robust three-link stainless steel bracelet with secure folding clasp provides both comfort and durability, with a standard 24mm lug width allowing for strap customisation should you wish to personalise your look. At Cassims & Co., we are proud to be an authorised retailer of FOSSIL watches, ensuring that every timepiece we offer is backed by genuine manufacturer support and complete authenticity.
The FS5991's dial layout is deliberately tool-focused: a date window at 3 o'clock with white contrast framing, bold geometric hour markers for instant readability, and a clean chapter ring bearing minute track gradations. The GMT hand, indicated by a contrasting pointer, completes its circuit every 24 hours, while the bezel can be rotated to track a third time zone—a feature that separates this model from standard three-hand dive watches. Whether you're timing a dive, coordinating across continents, or simply appreciating functional watchmaking, this Fossil delivers practical versatility in a compelling package.

FAQ
Q: What is a GMT function and how do I use it on this watch?
A: The GMT complication allows you to track a second time zone simultaneously. The 24-hour hand makes one full rotation per day, while the rotating bezel with its 24-hour scale can be set to display a third time zone. To use it, set the GMT hand to your home time, then rotate the bezel to align with the current time in another zone you wish to track.
Q: Is this watch suitable for swimming and diving?
A: Yes. With 10 ATM (100 metres) water resistance, the FS5991 is suitable for swimming, snorkelling, and recreational diving. The unidirectional rotating bezel can be used to time dives safely. However, avoid operating the crown or pushers underwater, and ensure the crown is fully pushed in before water exposure.
Q: How often does the battery need replacing in this quartz watch?
A: Quartz watch batteries typically last 2-3 years depending on usage. When you notice the seconds hand skipping or the watch losing time, it's time for a battery replacement. Our service team at Cassims & Co. can replace your battery professionally, ensuring water resistance is maintained.
Q: Can I change the steel bracelet to a different strap?
A: Absolutely. The FS5991 features standard 24mm lugs, making it compatible with a wide range of aftermarket straps including leather, rubber, or NATO-style fabric options. We can assist with strap changes and recommendations at our Mall of the South boutique.
Q: What does the unidirectional bezel mean?
A: A unidirectional bezel rotates only counter-clockwise, a safety feature in dive watches. If accidentally bumped during a dive, it can only indicate more elapsed time than actual, never less—ensuring you surface safely with adequate air reserves. On this GMT model, it also serves to track a third time zone.
Q: Is this an automatic or battery-powered watch?
A: The FS5991 uses a quartz (battery-powered) GMT movement. Quartz movements are highly accurate, require minimal maintenance, and eliminate the need for daily winding. Simply replace the battery every few years to keep your watch running precisely.
Q: Does Cassims & Co. provide warranty coverage on this Fossil watch?
A: Yes. As an authorised Fossil retailer, all our Fossil watches come with the full 2-year international manufacturer warranty covering defects in materials and workmanship. This warranty is only valid when purchased from authorised dealers like Cassims & Co., and we provide complete after-sales support throughout the warranty period.

- Authorised Retailer Requirement: Warranty validity requires proof of purchase from an authorised Fossil retailer such as Cassims & Co. Watches purchased from unauthorised dealers or third-party marketplaces may not be eligible for manufacturer warranty coverage.

Care Guide
- Daily Wear: Avoid exposing your watch to extreme temperatures, strong magnetic fields, or harsh chemicals including perfumes and cleaning agents.
- Water Resistance Maintenance: After exposure to saltwater or chlorinated water, rinse the watch with fresh water and dry thoroughly. Have the water resistance tested annually, especially before swimming or diving seasons.
- Crown Care: Always ensure the crown is pushed fully in after setting the time or date. Never operate the crown underwater or when the watch is wet.
- Cleaning: Clean the stainless steel case and bracelet regularly with a soft cloth. For deeper cleaning, use a soft brush with mild soapy water, rinse, and dry completely.
- Bracelet Adjustment: If the bracelet requires sizing or becomes loose, visit our boutique for professional adjustment to prevent loss or damage.
- Battery Replacement: When the battery requires changing, have it replaced by a professional watchmaker to maintain water resistance integrity and proper sealing.
- Storage: When not wearing your watch, store it in a cool, dry place away from direct sunlight. A watch box or soft pouch protects against scratches.
- Servicing: While quartz watches require less maintenance than mechanical timepieces, we recommend a professional service every 3-5 years to ensure optimal performance and longevity.
- Bezel Care: The rotating bezel should turn smoothly with distinct clicks. If it becomes stiff or gritty, bring it in for professional cleaning to remove accumulated debris.
