...О ещё совершенно брутальный корпус - склоняюсь всё - таки к тому, что широкое понятие часов (эталон) появилось именно как станционные на ЖД и они находились именно возле телеграфа, позже первичными для часов зала ожидания, перрона ... Когда телеграф пришёл в казённые учреждения эталоны пришли и туда, с более вычурными корпусами.

Вы как в воду глядели. Вот отличный образец такого взаимодействия - "WESTERN UNION SELF-WINDING REGULATOR"
Привожу текст описания с ebay:
"...This clock utilizes a battery-powered movement from the Self Winding Clock Company (SWCC) of New York . The company was formed in 1886 by Charles Pratt with Henry Chester Pond. With main offices at nos. 10 & 12 Dey Street, New York City, and a branch office at 39 Madison Avenue in Chicago , they were a major player in the clock industry until about 1970. In the 1932-1933 period the firm was about to go bankrupt so Western Union stepped in and bought them, At that point, SWCC continued building Western Union clocks based on the "F" movement that had been in production for the previous 24 years.
The design was based on automatically winding the clock each hour with a motor powered by two 1 1/2-volt dry cells located in the case. The advantage of his high-quality, pendulum-controlled movement, combined with the constant driving force of the small, frequently wound mainspring, was that it yielded a highly accurate clock subject to minimal wear.
Most of these clocks were actually owned by the SWCC subsidiary and leased to Western Union, who , in turn, rented the clocks and provided a wire circuit to energize the correcting mechanism once daily.
The railroads needed to coordinate among their stations (and among each other lest two trains sharing a stretch of track shared it too closely). In 1883, the U.S. Naval Observatory had agreed to telegraph standard railway time, which turned out to be a great boon for Western Union . An optional attachment allowed the clocks to be synchronized by hourly utilizing the correcting signal from the USNO which forced the minute and second hand straight up if the clock was was within a minute of the hour.
These clocks were common in government offices, schools, and other institutions and could be seen in all Western Union telegraph offices.
The basic clock movement was, at least originally, made by Seth Thomas for SWCC, as were many of the cases (see: Ly, T.D.,
American Clocks, Volume 2, 1991).
