The watch sale carries our 12 month workmanship warranty. The details are shown on the card below which will accompany the watch. The only limitation is against failure of components. Although trained by Patek Philippe to service this calibre I no longer have access to their spare parts, so if a component were to fail the watch would need to go to Patek Philippe for correction at the purchasers expense. What we can guarantee is that at the time of sale the watch is working perfectly and is in excellent condition internally following our full service. Also any failure of the movement which does not require new parts will be covered by our warranty and corrected free of charge.
