What time is it? Watches and horology

Well ASFAIK it's not strictly a copy of a droz, EPSA didn't make watches, just the cases and the outer dial, the unique part is the movement, inner dial and hands. Some brands changed the inner dial too but Longines specifically only made the top arrow hollow, hardly a significant change.

I maybe prefer the Helson as it doesn't have the date and the 'cock' hour hand is a little less obvious, and it doesn't have the script 'AUTOMATIC' type.

(you can see in the selection above it's the Enicar and Universal who have made the most effort to be different for the outer bezel)
