The below is an aggregation of all vintage minute repeating wristwatch audio I have been able to locate.
The audio qualities vary widely due to:
– lack of controlled environment, often you will hear movement and/or voices in the audio file
– range of volumes, which I have tried to increase as possible, though I chose not to increase to the point of introducing clipping into the track
If you know of any others, even videos from which audio can be extracted, please let me know. These are challenging to track down due to their rarity.
