The AJTT extract posted by cristos71 tells us almost everything.
The movement was a standard Omega 59-8D (which by this time had 15 jewels – went on later to become Cal.110).
The port of Barrow-in-Furness (north west UK) had built Royal Navy ships in WWI and WWII – including but not exclusively submarines.
These ships clocks were built by Omega for the ‘British Admiralty’ and supplied through their agents, the jewellers W.T.Story Ltd – and the dials were marked ‘STORY BARROW’.
The angled housing is (heavy) brass, secured as we see by a keyed lock.
Looking at Temprus’s clock, the crown is different, presumably a replacement. The other major difference is the dial – which is NOT the standard ‘STORY BARROW’.
I own more than one of these and the case and movement numbers are later (case numbers are 957****).
I attach two images. The first shows one of my clocks on the right of the Temprus clock and is (in my opinion!) original and typical in every respect. The second shows the two dials together – the STORY BARROW on the right is what I have seen on every one of the clocks I have seen (many were produced) and compares with the AJTT image.

So we come back to the question about differences in the Temprus clock/dial. Because of the earlier numbers, I suppose it’s possible that it was a prototype. Maybe it is a replacement dial from a different Omega? Seems unlikely.
