I haven't heard the latest one they launched a couple months ago.
The other thing is that each brand needs to have a program where the original sound is recorded in a very rich, high quality format, in a recording studio, and then when the watch is serviced, it is tuned to sound similar. So many watches sound great when they leave the factory. But invariably these things need service, and after that they sound awful sometimes or they don't sound like what they used to. So a recording has to be kept. Patek Philippe does keep a recording supposedly. As does Vacheron Constantin. I don't know if any other brands have a formal program where they keep a recording.
