The history of navigation and the development of marine clocks. During the Renaissance, mankind came up with many sensible solutions to many hard questions plaguing the human spirit. One main focus remained the exact determination of one’s position at open sea. Geographic latitude was quite easy to determine by measuring the vertical angle between the sun or another fixed star and the horizon. The necessary tools, such as sextants, were familiar to sailors. Much more difficult was the determination of the equally important longitude. At first, seamen estimated their positions according to their logbook notes. This unfortunately resulted in week-long odysseys and shipwrecks. The only authentic really precise method for determining longitude needed the help of mechanical board chronometers. It was known at the time that correspondence between the geographical longitude and the reference time at the last harbor set by a board clock could determine position: the location of the stars was determined by the date, the time, and the longitude. If one knew the first two parameters, the longitude was the result of the observed positions of the stars. Marine Clocks To calculate longitude with the precision of one arced minute, the ship’s clock may not deviate more than one second per day. This grand challenge led to the creation of a competition with attractive monetary prizes for the precisely defined determination of longitude. The English parliament in its 1714 Longitude Act called for a million-pound sum as the reward for solving the problem, which raised a healthy competition. The only true solution was presented by 66year-old carpenter John Harrison in 1759: his standard-setting invention went to sea from November 1761 until January 1762. After a total of 81 days, the heavy H4 pocket watch, weighing about one and a half kilograms, displayed a deviation of only five seconds – and the first chronometer was born. But that’s all in the past. Today, modern electronics and a global satellite system make orientation possible to the meter. Nevertheless, it is recommendable to carry an instrument on board whose batteries do not run out and whose electronic chips don’t break down: the Nautis and the Navis are the Erwin Sattler manufactory’s conventionally ticking, mechanical precision clocks. 69
Carbonautis Rosé gold-plated Dimensions: Width 34 cm Height 19.7 cm Depth 5 cm Weight 1,5 kg The Nautical Multipurpose Instrument – Carbonautis – Precise Quartz Clock with Barometer, Thermometer, and Hygrometer Keeping in step with our present high-tech age, Erwin Sattler presents the Carbonautis, a multipurpose instrument made from such modern materials as carbon fiber and aluminum. In the same way that a high-tech sports car represents the combination of several elements into a unique whole, these four instruments are combined into a single elegant and extraordinary unit. The clock’s dial and the precision twin barometers are made of carbon fiber and have two applied, milled, and anodized aluminum scales. To facilitate the legibility of the changes in 70 71 Nickeled air pressure, the barometer also has a manually adjustable reference needle in the glass. Stainless steel or rose gold-plated needles indicate the temperature and humidity on the anodized aluminum dials of the laterally fitted instruments. The milled, glass bead-blasted and nickel-plated case, crafted from a single solid block of aluminum, sports a form-fitted, anti-reflective mineral crystal. To ensure simple, secure installation, the 4 mm thick base plate of the ensemble is attached to an aluminum mounting plate using four polished knurled nuts. An individually engraved plate with the serial number makes each Carbonautis unique.
