Ulysse Nardin Marine Chronograph Annual Calendar Watch perfectly shows the Swiss brand’s amazing mechanical achievement. Its annual calendar provides a mechanical solution which is easy to use and which is adjustable both on the front and back.
The beating heart of the watch is the impeccable caliber UN-153 which is entirely manufactured in-house including the silicium balance-spring and escapement made by Sigatec, a company that is co-owned by Ulysse Nardin. The self-winding movement oscillates at the rapid frequency of 28,800 alternation per hour (4 Hz) and it is capable to store enough energy to keep tracking the time for approximately 52 hours. The interestingly designed mechanism allows the time and calendar pointers to be moved in either direction.
The annual calendar complication of the new Marine Chronograph Annual Calendar is something between a perpetual and a regular model. While most timepieces equipped with a calendar function need constant adjustment to ensure that the correct date is always displayed, an annual calendar displays day, date and month with a minimal user intervention. This complication only requires adjustment once a year at the end of February because it only recognizes months with 30 or 31 days.
Besides the annual calendar feature, this watch also incorporates a chronograph feature. Apart from the central hands which indicate hours, minutes, and seconds, there are also a 30-minute chronograph sub-dial at the 3 o’clock position, the 12-hour counter at the 6 o’clock position, and the small second counter which is located at the 9 o’clock position. The latter also comprises a month display which includes sub-dials offering useful guide-marks when setting. The exact date of a month is available at the 6 o’clock position.
Ulysse Nardin Marine Chronograph Annual Calendar Watch is housed in a round case measuring 43mm in diameter. The case incorporates a ribbed bezel and a screw-down crown that offer decent water resistance up to 100 meters (330 feet), thus making the watch a perfect sailing instrument.
The Swiss manufacturer offers 10 various versions to fit various tastes. There is a choice between a stainless steel case and the 18-karat rose gold one. Also, customers can choose between white and blue dials, and the last choice is among different types of wristlets: leather, rubber or steel ones.
The retail price depends on the model. The stainless steel model with the rubber strap is the most affordable one with the price of $11,800. The next in a row is the steel cased watch attached to the alligator strap which can be purchased for $11,900. All steel versions come with the retail price of $12,600. The rose gold model with the alligator leather strap is priced at $33,000, while the one teamed up with a rubber strap is available for $34,600.
