Tempus Mobile-Precision Shipclock with World Time Indication and Gimbal Suspension
In the past few years, clock manufactory Erwin Sattler has
extended its collection to include a department for marine
clocks. The high-quality maritime timekeepers can today be
found in the salons of numerous luxury yachts whose prices
range in the millions.
The newest model of this line developed with a great deal of
imagination is the Tempus Mobile, outfitted with a function
unique in the world – one that has proven itself particularly on
sailing yachts.
A sailboat only remains horizontal in the water if it is running
before the wind, when the wind and the direction of travel
coincide.
All other courses, especially when sailing head to wind,
will see the boat leaning to the side that is positioned away
from the wind. The 43-centimeter-high Tempus Mobile
(Latin for »mobile time«), whose case is held in a gimbaled
ball bearing ring held by three stainless steel columns, displays
the heeling of a sailboat in angular degrees.
The tip of its funnel-shaped case swings between the
rings along a base of polished granite providing a home for
the scale normally delivered with divisions ranging between
0 and 15 degrees. Sporty sailors can request a scale
providing measurements between 0 and 21 degrees.
The permanent world time display is very practical on long
sailing voyages along the lines of latitude: its display ring
on the lower edge of the case cylinder makes one revolution
every 24 hours.
The time is indicated on the unusual clock by a regulator
display (central sweep minute hand, subsidiary dials for hours
and seconds), the previously usual type of display for
observatory clocks and marine chronometers.
Additionally, the Tempus Mobile is outfitted with a power
reserve and 24-hour display. The latter is separately
correctible and can be set to show either a second time zone
or a day/night indication.
Its clock is outfitted with the manufacture movement of the
Nautis marine clock, which brings a good two weeks’ power
reserve with it. A cutaway in the subdial for seconds allows
a view of the balance of the Swiss échappement, a complete
subgroup screw-mounted to the top of the movement that
contains the escapement and the balance.
