Patek Philippe 7140 Ladies First Perpetual Calendar
Written By: D Constant for The Watch Review Site
We look at the Patek Philippe 7140 Ladies First Perpetual Calendar and we can clearly see that the growing love affair of women with mechanical watches and complicated functions is one of the great current trends in the world of horology. That must be the reason Patek Philippe saw fit to launch the 7140 Ladies First Perpetual Calendar before any of its new Men’s novelties in 2012.
Could their decision also be based on the response to the Ladies First Chronograph launched by Patek Philippe in Autumn 2009, along with further ladies complications launched 2 years later in 2011, being an ultrathin split-seconds chronograph and a minute repeater. Now in 2012 with the Patek Philippe 7140 Ladies First Perpetual Calendar, they hope to fasscinate every woman with a penchant for the pinnacle of watchmaking artistry and with the perpetual calendar, a grand complication that qualifies as an incarnation of eternity with its functionality, lasting value, reliability across generations, timelessly elegant design, and enduring array of diamonds. The workshops’ design team and the complications ateliers spared no effort to endow this complicated timepiece with an irresistibly feminine personality.
The Ref. 7140 Ladies First Perpetual is beautiful and everlasting
This was Patek Philippe’s objective and it has been accomplished with panache and style. All of the elements of this elegant timepiece reflect feminine poise, from the classic round Calatrava case in 18K rose gold and the gracefully curved lugs to the shimmering creamy white dial, the interchangeable mink gray and royal purple alligator straps, the lovely bezel, and the clasp set with precious diamonds that deserve to be called a girl’s best friend.
The dimensions of the case are suited to a feminine wrist with its compact diameter of 35.10 mm and a height of 8.8 mm. Still even though it is neatly designed in a compact package the ref. 7140 Ladies First Perpetual still has eight indications, these being hours, minutes, date, day of the week, month, leap-year cycle, 24-hour subdial, and moon phases. All of these are well organised on the dial and are clear and easily read. This is achieved by the contrasting components to the White Opalescent Dial
The Patek Philippe 7140 Ladies Perpetual Calendar has no less than 68 Top Wesselton diamonds totaling approx. 0.68 ct. on the dial. The Ladies Perpetual Calendar comes with a solid-gold case back and an exchangeable sapphire-crystal display back that allows you to admire the magnificently intricately designed and artistically decorated mechanical caliber 240 Q. This is A Patek Philippe legendary caliber, which is assembled in the manufacture’s ateliers for it’s complicated watches.
Composed of 275 individual parts, it is only 3.88 high, despite the fact that it is self-winding. This feat was made possible by recessing the off-center 22K gold minirotor in the plate, combined with an ingenious arrangement of the mechanisms for the perpetual calendar and the moonphase display. A key feature is the 7140 Ladies Perpetual Calendar’s mechanical memory of 4 years, which allows the perpetual calendar to always indicate the correct date, automatically taking into consideration the months with 31, 30, or 28 days, and the 29th of February in leap years. This means that as long as the 7140 Ladies Perpetual Calendar is worn regularly and not let to run down the Ladies Perpetual calendar will take until 2100 before the calendar has to be manually adjusted and at that point it will only be by one day. So we have a watch if worn regularly that will most likely outlast you and see you to the grave (for want of a better term) or just think this is definately one for the family collection.
This timepiece has been designed for eternity and is has a hand-stitched alligator strap with a prong buckle in 18K rose gold which has a further 27 Top Wesselton diamonds totaling about 0.20 ct.
The Ref. 7140 Ladies First Perpetual Calendar definately adds to, and enhances Patek Philippe’s collection of ladies’ watches and we look forward to the next installment in Patek philippes portfolio of complicated watches for women.
