Buy Certified Pre-Owned Fortis Watches in Switzerland

Fortis was founded in Grenchen in 1912 by Walter Vogt and built its reputation on instrument-grade reliability rather than display. In 1926, the brand produced one of the first mass-manufactured automatic watches in collaboration with John Harwood, the British inventor of the self-winding wristwatch. Since 1994, Fortis has served as the official supplier of timepieces worn by Russian cosmonauts aboard the Mir space station and later the International Space Station, a partnership that continues to define the brand's identity in aviation and space instrumentation.

At WATCHOYSTER, we carry a selection of certified pre-owned Fortis watches inspected in Switzerland. Every piece has been physically examined by our in-house certified watchmaker, verified against The Watch Register, and documented before listing. What you see reflects the actual condition of the watch, with no exceptions.

Why Buy Pre-Owned Fortis

Fortis occupies the accessible end of the Swiss instrument watch segment, offering space and aviation certification credentials rarely found at comparable price points elsewhere in the market. The pre-owned market is where earlier Flieger, B-42 and Official Cosmonauts references become available, often well below their original retail price. Buying a certified second-hand Fortis from a verified dealer in Switzerland means every piece has been assessed for movement accuracy, case condition and water resistance integrity before listing. Our 12-month warranty applies to every watch in our catalogue, and our 14-day return policy covers any case where the watch does not correspond to its description.

Purchase Conditions

All Fortis watches in our catalogue are available for immediate purchase with worldwide insured delivery. Standard delivery across Switzerland takes 2 to 3 business days. For clients who prefer to inspect the watch in person before completing the purchase, our appointment-only lounge in the Geneva Free Zone is available by prior arrangement.

0% financing is available on selected pre-owned Fortis references for clients based in Switzerland, with terms from 3 to 24 months, no interest and no administrative fees. The full purchase price is divided into equal monthly instalments, with a minimum first payment of 25%. A decision takes under three minutes at checkout, with no documentation required beyond standard order information.
