Mechanical clock movement striking ship's bells

The ship’s bell strike movement is suitable for a brass casing with hinged brass bezel. As I have not listed it in my pages yet, here are some options:

Ship’s Bell Strike

Unlike public and domestic clock bells (or gongs), the strikes of a ship’s bell do not match the numbers of the hours. Instead, there are eight bells, one for each half-hour of a two or four -hour watch.

In the age of sailing, watches were timed with a 30-minute hourglass, hence the German expression “Glasen”. The Sailors on Watch duty would turn the  hour-glass and strike the ships bell  according to the bell pattern below. (Half  of a 24 – hour period)

Number of bells Bell pattern  half of a full period
One bell 1 12:30 04:30 08:30
Two bells 2 01:00 05:00 09:00
Three bells 2 1 01:30 05:30 09:30
Four bells 2 2 02:00 06:00 10:00
Five bells 2 2 1 02:30 06:30 10:30
Six bells 2 2 2 03:00 07:00 11:00
Seven bells 2 2 2 1 03:30 07:30 11:30
Eight bells 2 2 2 2 04:00 08:00 12:00

a) I can sell the movement as a trade deal, all functions are working well. But the movment has been in stock for a long time and needs a service ( no bushes to be replaced ) I supply a brass dial, 150 mm diamter, roman numbers engraved, filled in black, no winding holes drilled, two slots for regulator and strike switch-off to be made. ( The backplate is the guide )

b) I do all that work and fit the complete unit into your casing

c) I will try and get a brass casing and fit the clock complete

d) I will have one of my oblong “Port – Hole” brass casing re-furbished and fit the clock movement with dial and a suitable barometer into that casing.

Once I have more details about casings, I will list them in my pages with more details on the movement.
