Our 4-6 week turnaround time and free fully insured postage means you can access Official Fortis servicing from anywhere in the UK without visiting our Hatton Garden workshop.

We recommend servicing your Fortis watch every 4-5 years for most models to maintain optimal performance, though professional instruments subjected to extreme conditions may benefit from more frequent servicing.

However, you should bring your Fortis in sooner if you notice:

• The watch is running fast or slow (more than the COSC chronometer specification)

• Condensation or moisture under the crystal (critical for dive models)

• The crown feels loose or difficult to wind

• Any unusual sounds when the watch is in motion

• Issues with chronograph functions or slide rule calculations (B-47 models)

• Visible damage to the case, crystal, or bracelet

• Problems with the unidirectional rotating bezel (for dive models)

• Luminous material degradation affecting legibility

As an Official Fortis Service Centre, our certified watchmakers ensure your timepiece maintains its accuracy, water resistance, and the professional-grade reliability Fortis has delivered to pilots, cosmonauts, and diving professionals. All our Fortis Full Services include a 2-year warranty for complete peace of mind.

Yes, absolutely. As an Official UK Service Centre for Fortis, we exclusively use genuine Fortis manufacturer parts for all repairs and servicing. Using authentic Fortis components is essential for:

• Maintaining your watch's value, authenticity, and warranty status

• Ensuring optimal performance and chronometer-grade accuracy

• Preserving water resistance to original specifications

• Protecting your investment long-term

• Maintaining official Fortis service history

• Preserving professional instrument certification (where applicable)
