ad 1: I assume you mean the 1846 Marine Chronometer, not the Chronograph. You are right, there are currently two different dials with Roman numerals available:
a) white lacquer with printed Roman numerals, and
b) silverized with embossed Roman numerals.
The former can be distinguished already by the watch's reference number, since it ends with /40, while the latter has reference numbers ending with /30.
The embossed numerals are a bit larger than the printed ones. For me personally, the white lacquer version is more desirable, since it is closer to the dials of the original ship's chronometers, while - as you stated already - the embossed numerals have a nice three dimensional effect of depth.
Originally, there were also blue dials with embossed Roman numerals, but I could not find these in the lists any more, only the blue dials with embossed Arabic numerals.
ad 2: The San Marco Alarm is one of the longest serving UN watches in the line. While having disappeared from the catalogues since at least four years, it is still available new from UN, at least in the US. As most other alarm wristwatches of its time, it is equipped with a Schild AS 5008 (or was it 5001?) automatic alarm movement, that is also used by Maurice Lacroix, and - with additional GMT module - by Girard Perregaux and Baume & Mercier. Many other companies used this movement as well. Most movements were NOS, but since some time, Dubois-Dépraz is producing the whole movement for its customers. If I recall the facts correctly from my leaky memory, the movement uses two spring barrels, one for the movement and one for the alarm, but the automatic winding mechanism is winding both of them simultaneously. The movement's biggest disadvantage is its lack of alarm noise, it only has a very decent, not unpleasant sound, which again makes it an advantage when using it as a mere appointment alarm, in a meeting, for example.
There are two versions available from UN, one with a standard date window, the other, more unique one, with a pointer date. The calendar hand is located under the dial, and its red or silver tip is indicating the date through a series of small apertures beside the date numerals.
Case diameter is 38.5mm
Hope this helps.
