I will give you a 1 year guarantee on “my work”. I won’t be responsible for any original part that may fail after service. ALL warranty work must be returned to me for repair.
I will NOT guarantee any vintage watch to be waterproof even if it has just had new seals and gaskets. I would suggest that every vintage watch be kept as clean and dry as possible.
I will only pressure test a Rolex or NEW Omega Seamaster to check water resistence.
The warranty is voided if: The watch has moisture inside the case; The balance staff is broken (This means the watch was dropped); The crystal is scratched or broken; If the case has been opened / tampered with, the guarantee is void. Most all wristwatches need to have their case backs opened by a professional with the proper tools. The warranty is not transferable if the watch is sold.
Accuracy levels will vary with the age, condition and service history of your watch. A newer Rolex in good running condition should meet Chronometer standards of -2 to +6 seconds a day. An older model (1570) may meet those standards but it will vary according to movement condition and its service history. Rolex recommends that their watches should be serviced every 3-5 years.
A vintage mechanical watch from the 60-70’s can’t be expected to run this accurately. It may run this well, but I can’t guarantee it. Depending on the movement, it should be in the 10-15 seconds fast a day. Most of these watches also can’t be considered water resistant because of their age and case, crystal and crown wear. Vintage watches should be kept as clean and dry as possible.
Please keep in mind that no watch, not even a Rolex will last forever, everything wears out at some point!! I will do my best on each overhaul to get the watch as accurate as possible, but there are limitations of what I can and can’t do on every repair job.
