Question 1

Does it automatically receive and sync its time from an *external* source, such as the WWVB Atomic Clock time signal transmitted from Colorado?

Accepted Answer

The watch does receive a signal from Colorado. The user guide says to put the watch in or near a window to receive the signal each night between 1 a.m. and 4 a.m.

Question 2

Does this watch automatically keep the correct day/date?

Accepted Answer

Yes, time and date seem to be automatically updated (I don't understand the technical workings but it does work).  I have had no problems with mine, and other than being a larger watch than I am used to,  I am very satisfied.

Question 3

Tiempo de duracion de la bateria

Accepted Answer

Battery = CR1616
Battery life = Approx 3 years

Question 4

How to go the 24 hour mode?

Accepted Answer

NOTE: the instructions refer to buttons A, B, C, D, in this layout.

A    B

C    D

Hold A down until City code flashes (bottom left).
If city is not London (Lon) use button B or D (both on right)
to cycle through city codes. B moves west, D moves East.
Madrid (MAD) is east of London so press B,
Lisbon (LIS) is west of London, so press D.

When LON is set (flashing), you can then cycle through the following operations, setting states using button C, and using buttons B and D to alter each state. (B and D make changes in opposite directions.)
When you get back to City (LON flashing) press A to exit to normal mode:

So: hold A (top left) for a while to get city flashing then cycle through these modes by pressing button C (bottom left)

City -> DST (on off auto) -> 12/24hr format -> Seconds -> Hour
    -> Mins -> Year -> Month -> Day
    -> Language (EN) -> Toggle Month/Day|Day/Month format
    -> City (Exit by pressing A)
In each of those setting modes:
    Use D to cycle between two or three options (e.g. 3 options for DST
    and two options for 12/24, or M/D, D/M format).

For setting seconds use D to set to 00

When there's number to set (year, month, day, etc.)
    Use D for +1, B for -1.

[The year shows as two flashing digits bottom left in year setting
    state. Set to 14 in 2014]
When a state is set as desired press C to go to next setting mode.

When you get back to City, press A to exit setting mode.
