The Jaeger-LeCoultre Master Ultra Thin Perpetual ref. 1302520 is nothing but elegant and a very easy-to-read perpetual calendar featuring the traditional Jaeger-LeCoultre one push piece corrector for all complications on the calendar. Once the calendar is set, it needs no adjustment until 2100. The perpetual calendar mechanism takes into account the length of each month and takes into account the 29th of February for every leap year.                                                                                                             

This elegant watch is fitted with a very thin rose gold case measuring 39mm in diameter and only 9.2mm in thickness. The cream color eggshell dial is perfectly balanced with an uncluttered configuration featuring rose gold applied markers, recessed indicators for the moon phase at 12, day of the week at 9, date at 3, month at 6, a small year aperture between 7 and 8 o'clock and a small night/day indicator via a very small aperture above the central pinion. To round up its elegant look, the watch is fitted with dauphine hands and a blue anodized seconds hand that provides the ultimate contrast.

This watch is fitted with a dark brown alligator strap with pin buckle that is comfortable but somewhat short. Those with wrists larger than 7-7.25" will find it difficult to wear this watch unless the strap is secured on its last hole.  

The Master Ultra Thin Perpetual is fitted with a display case back that allows for full view of the beautifully finished Jaeger-LeCoultre automatic calibre 868 composed of 336 parts, 46 jewels and which beats at a frequency of 28,800 vph providing a power reserve of 43 hours when fully wound. 

On the wrist, the watch wears very light —it weighs only 77 grams— and true to its size. The wrist presence and understated elegance of this timepiece is unparalleled. A fascinating perpetual calendar that wears as nice with a suit, as it does with casual clothes, which is something we don't say often about timepieces that are this elegant. This watch is also available in white gold —featuring a silver moon on the moon phase disc— and in stainless steel which is the best value for your money when it comes to a perpetual calendar with this pedigree priced right under $20,000 USD.
