The luxury watches from Ulysse Nardin have been extended by the watch manufacturer to include further models from the Marine Chronometer series. Ulysse Nardin's Marine model has a DIAMonSIL and silicon core - innovative materials that were already used in Ulysse Nardin's UN-118 calibre built in 2011. Today, the movement is one of the most important steps towards absolute precision in mechanical time measurement. The Ulysse Nardin Marine movement combines Ulysse Nardin's patented spiral spring with an innovative anchor escapement made of DIAMonSil and equipped with an integrated oscillator. The automatic movement serves in particular as a basis for the permanent independence of the company as well as for its future development. In addition, the UN-118 calibre is regarded as the highlight of the Swiss luxury watch manufactory, which has an hour and minute display as well as a small second with a direct drive.
