They also have the 4-second key-closed, 1-second key-open markings
to help manually send the signals that trigger the auto alarm in
other vessels on 500 kHz.
Some also had a moveable additional smaller hour hand that could be
positioned to show GMT, while the main hour hand showed local time.

I would guess not. Such clocks with U.S. Maritime Commission
markings in working condition routinely sell for about $400.
"Upgrading" the works would impact the collector value adversely,
so that becomes part of the cost.
