I recently purchased a vintage Girard Perregaux from the 1960s and the noise coming from the movement seems to be very loud. Is this normal for vintage watches to make a loud ticking noise like this? I have a vintage 1952 Hamilton Fleetwood as well and it makes a noise but is not as loud as the GP. Is there anyway to make the noise quieter or do I just have to deal with it? Also, what could be causing the the noise coming from the movement to be so much louder?
