Description
The Fossil Neutra Moonphase FS5903 is a masterclass in accessible complication watchmaking, combining classical astronomical functionality with contemporary design language. This multifunction quartz timepiece features a deep blue sunray dial punctuated by a moonphase display at 6 o'clock, flanked by day-date subdials that elevate this watch beyond simple timekeeping into the realm of genuine everyday utility. The 42mm stainless steel case strikes an ideal balance between wrist presence and wearability, while the warm cognac leather strap with contrast stitching adds a refined, artisanal touch that complements both business and casual wardrobes.
At Cassims & Co., we recognise the Fossil Neutra collection as a compelling proposition for those who appreciate horological complications without the mechanical price premium. The quartz movement ensures accuracy within seconds per month, while the moonphase complication tracks the lunar cycle with poetic precision—a feature traditionally reserved for far more expensive mechanical calibres. The blue dial's concentric guilloché texture catches light beautifully, creating depth and visual interest that belies the watch's accessible positioning.
Water-resistant to 5 ATM (approximately 50 metres), the FS5903 handles daily exposure to moisture with confidence, though it is not intended for swimming or water sports. The applied indices and gold-toned hands provide excellent legibility against the rich blue backdrop, while the 22mm interchangeable strap system allows for effortless personalisation. Whether you're drawn to the celestial romance of the moonphase complication or the practical utility of the day-date displays, this Fossil delivers exceptional value and visual impact.
This timepiece represents the best of Fossil's design philosophy: democratising complications that were once the exclusive domain of haute horlogerie. Browse our full range of FOSSIL watches to explore the brand's diverse catalogue, or visit us at our Mall of the South boutique in Johannesburg to experience the Neutra Moonphase firsthand. Our watch servicing and repairs team is always available to ensure your Fossil timepiece maintains its precision and appearance for years to come.

FAQ
Q: What is a moonphase complication and how does it work?
A: The moonphase complication displays the current lunar phase through a rotating disc visible through an aperture at 6 o'clock on the dial. It tracks the 29.5-day lunar cycle, showing the progression from new moon through full moon and back. This quartz-driven moonphase requires manual adjustment approximately every 2.5 years to maintain accuracy, a simple procedure detailed in the owner's manual.
Q: Is the Fossil Neutra FS5903 suitable for swimming?
A: With 5 ATM (50 metres) water resistance, this watch can handle splashes, rain, and brief immersion such as handwashing, but it is not designed for swimming, showering, or water sports. The leather strap is also not recommended for prolonged water exposure, as it may deteriorate with repeated moisture contact.
Q: How often does the battery need replacing in this quartz watch?
A: Fossil quartz movements typically provide 2-3 years of battery life depending on usage patterns and complication activity. When replacement is required, visit Cassims & Co. and our technicians will install a genuine replacement battery and pressure-test the case to maintain water resistance integrity.
Q: Can I change the leather strap myself?
A: Yes, the Fossil Neutra features a standard 22mm lug width compatible with quick-release spring bars or traditional spring bar tools. Any 22mm strap—leather, NATO, rubber, or metal bracelet—will fit. We stock a selection of replacement straps at our Johannesburg showrooms and can assist with fitting.
Q: What is the accuracy of this quartz movement?
A: Quartz movements are inherently more accurate than mechanical calibres, typically running within ±15 seconds per month. This precision makes the Neutra an excellent choice for those who prioritise timekeeping accuracy alongside complications like moonphase and day-date functionality.
Q: Does this watch come with the full Fossil international warranty?
A: Yes, when purchased from Cassims & Co., an authorised Fossil retailer, this watch includes a 2-year international manufacturer's warranty covering defects in materials and workmanship. The warranty does not cover battery replacement, normal wear and tear, or damage from misuse.
Q: How do I set the moonphase display correctly?
A: Consult a lunar calendar to determine the current moon phase, then use the crown (typically in position 2 or via pusher) to advance the moonphase disc until it matches the current phase. The instruction manual included with your watch provides detailed setting procedures specific to this model.
Warranty
- Manufacturer Warranty: This Fossil watch is covered by a 2-year international warranty from the date of purchase, valid when purchased from an authorised retailer such as Cassims & Co.
- Warranty Coverage: The warranty covers manufacturing defects in materials and workmanship under normal use conditions. This includes defects in the case, dial, hands, movement, and bracelet or strap hardware.
- Warranty Exclusions: The warranty does not cover normal wear and tear, scratches or cosmetic damage to the case, crystal, or strap; battery replacement; damage caused by accidents, misuse, or improper handling; water damage resulting from failure to observe water resistance limitations; or unauthorised repairs or modifications.
- Water Resistance Note: Water resistance is not a permanent condition and may be affected by ageing gaskets or accidental impact. The warranty does not cover water damage if the watch has been used beyond its stated water resistance rating or if the crown was operated while wet.
- Warranty Claims: To make a warranty claim, present your watch along with the original purchase receipt to Cassims & Co. We will assess the issue and liaise directly with Fossil to facilitate repair or replacement as determined by the manufacturer.
- Battery Replacement: Battery replacement is considered a consumable service and is not covered under warranty. However, Cassims & Co. offers professional battery replacement services at competitive rates, ensuring your watch is properly sealed and tested after service.
- Authorised Retailer Guarantee: This warranty is only valid when the watch is purchased from an authorised Fossil retailer. Purchases from unauthorised dealers, grey market sources, or third-party online marketplaces may void warranty coverage.
Care guide
- Daily Wear: Avoid exposing your Fossil Neutra to extreme temperatures, strong magnetic fields, or impacts that could affect the quartz movement or damage the case and crystal.
- Leather Strap Care: Keep the leather strap dry whenever possible. Remove the watch before swimming, showering, or engaging in activities that cause excessive perspiration. Wipe the strap with a dry cloth after wear and allow it to air dry completely if it becomes damp.
- Cleaning: Clean the stainless steel case with a soft, lint-free cloth. For deeper cleaning, use a slightly damp cloth with mild soap, ensuring no moisture enters the case. Dry thoroughly with a soft cloth. Avoid chemical cleaners or abrasives.
- Water Resistance Maintenance: Have the water resistance tested annually if you frequently expose the watch to moisture. Gaskets and seals can degrade over time, reducing water resistance. Never operate the crown or pushers while the watch is wet or submerged.
- Storage: When not wearing your watch, store it in a cool, dry place away from direct sunlight. Avoid storing near strong magnets or electronic devices that emit magnetic fields, as these can affect quartz movement accuracy.
- Battery Replacement: When the watch stops or the seconds hand begins jumping in 4-second intervals (battery low indicator on some models), have the battery replaced promptly by a qualified watchmaker. Extended periods with a depleted battery can cause leakage and movement damage.
- Servicing Schedule: Quartz watches require less frequent servicing than mechanical pieces, but we recommend a professional inspection every 3-5 years to ensure gaskets remain intact, the movement is functioning optimally, and the case remains properly sealed.
