Ulysse Nardin Nautical Chronograph Annual Calendar
The actual Marine Chronograph Year Work schedule is a typical Ulysse Nardin product as it offers a large amount of innovation and ingenuity in a relatively low price. It has an inner chronograph movement and a calendar that can be adjusted backwards and forwards, a system invented by Ludwig Ochsling.
The wathe is rendered very well. The particular quarter-second scale on the internal bezel flange has triangles at the hour markers, rewarding the watch’s resemblance to some compass. The subdial shows a 30-minute chronograph in 3 o'clock, a 12-hour chronograph at 6 o'clock and a continuous seconds hands at 9 o'clock. The only real less practical feature may be the date window at six o'clock, which blocks section of the chronograph hour sub-dial among 5 and 7 hrs. The chrono buttons tend to be nicely recessed and they are hardly visible from the top.
The watch is available in a number of versions, the main choice becoming an eggshell white dial along with black dial indicators or perhaps a dark blue dial together with white indicators. In the rose gold colored version, the dark glowing blue dial is paired with precious metal Roman numerals. The band is made of leather or rubberized with a folding clasp. The situation is 43mm in size, with a screw-down crown as well as 100m water resistance. The ribbed bezel reinforces the Ulysse Nardin connection to the sea world. The hour and also minute hands are shown by differently shaped " classic hands", which are correspondingly painted with white round and diamond-shaped areas, possibly fluorescent lacquer.
The UN-153 motion was designed entirely in one facility, and its annual calendar functionality was developed from the simple work schedule of the existing UN-118 movements. The annual calendar component reflects the work of Ludwig Oechslin, a designer that has created many of Ulysse Nardin's most innovative creations whose characteristic is the pursuit of extreme simpleness. Just add three additional wheels and the watch may take into account the length of the different a few months. It only needs to be adjusted annually at the end of February. In another signature bank feature of the Ulysse Nardin, the calendar can be adjusted ahead and backwards from the overhead. This is more user-friendly compared to strap buttons in most yearly and perpetual calendar timepieces that have to be pressed having a stylus. The date windowpane has a magnifying glass for simple reading.
The total amount wheel vibrates at twenty-eight, 800 vibrations per hour (4 Hz), and the balance springtime and escapement are also produced in-house by the Athens-based organization Sigatec using the antimagnetic materials silicon. The oscillating bodyweight with two anchor designs, one on each side, is visible through the sapphire caseback. This timepiece is self-winding and has an electrical reserve of 52 several hours. It looks like the chronograph is actually lever operated and has absolutely no crown wheel.
