My Rolex watch from the early 1980s was given a full service costing way over 1,000 Pound in 2018. The watch timing was off over a few minutes per week. They agreed to reset the timing again in 2020 and then started to lose time. Brought it back to Rolex, St. James Square, London and wanted 1000 Pounds to reset the time again in 2023. My conclusion is don`t buy a Rolex and use an independent watchmaker to repair.
