I've noticed that many English repeaters had hidden repeater works and gongs. However by the latter part of the 19th century many were visible.

This is in contrast with Swiss repeaters which are all visible.

Was this simply a stylistic choice or was it more technical? Maybe it had to do with the use of Swiss repeating modules?

Part is structural. The English used mostly full or 3/4plate movements. These were usually secured with case screw to the case rear lip. The top plate has to cover the gongs to secure the movement in the case.

However some English style watches did have visible gongs

The repeat work in this one is probably Swiss.

Yes I was curious about the fact that all of the English repeaters were full or 3/4 plate movements but some had visible gongs and others were hidden away. The exposed gongs seems to be mostly in late 19th century watches.

Perhaps the English deemed it vulgar to expose the gongs.

I wonder if there was some effect on the sound quality with hidden vs visible?

Here is my Barraud with invisible repeater works. It also has its assembly record from Usher & Cole that happened to be published in a book. I had the book before I had the watch. I was the back bidder on this watch twice at auction. The second time, I saw who was competing and decided I would try to buy it from them.

This is my web page on the watch: AWCo Web

I used to have this Frodsham by L. Audemars from 1869 with hidden gongs in the English style and I assume Frodsham ordered it that way. I have a .MOV file of the chimes but can't figure how to upload here.
