It is louder than most modern watches. It is a pocket watch movement, chronometer grade. Durowe D5.
The new/old movement is made from approx 90% original ww2 era parts. It is not a Durowe D5 movement, as it lacks one of the jewells ( 21 as oposed to 22 fo the Original. Maybe it should be called a D6?
I guess the new version sounds the same as the old one. I have a 1944 example. It has a faint, soft ticking, but still I can hear it when the watch sits on the bedside table.
