Fortis watch repair FAQs
What type of watches does Fortis produce?
Fortis is a Swiss watch manufacturer known for producing professional tool watches, particularly aviation and space-inspired models. Fortis watches are typically automatic or mechanical, built for durability and accuracy rather than fashion use.
Do Fortis watches require specialist mechanical servicing?
Yes. Most Fortis watches use high-quality Swiss automatic movements, which require proper mechanical servicing rather than simple part replacement. Regular servicing helps maintain accuracy, lubrication, and long-term reliability.
How often should a Fortis automatic watch be serviced?
A Fortis automatic watch should generally be serviced every few years, depending on usage and condition. Over time, oils degrade and components wear, which can affect timekeeping if servicing is delayed.
What are common issues seen with Fortis watches?
Common issues include reduced accuracy due to ageing lubricants, crown or stem wear, worn seals affecting water resistance, and general movement wear on watches that have not been serviced regularly.
Can you work on Fortis chronograph watches?
Yes. Many Fortis models feature chronograph functions, which require careful adjustment and testing. Chronograph watches benefit from specialist diagnosis to ensure pushers, timing functions, and reset mechanisms operate correctly.
Do Fortis watches need pressure testing after servicing?
Yes. Many Fortis watches are designed to be robust and water-resistant, particularly pilot and tool models. After opening the case, pressure testing is recommended to ensure water resistance is maintained.
What if my Fortis watch cannot be brought in personally?
If visiting us in person isn’t convenient, your Fortis watch can still be assessed and repaired via our fully insured send-in repair option, with clear communication and approval before any work is carried out.
