It’s Press Day at Baselworld 2014, and Patek Philippe has unveiled two new chronograph watches in steel cases, the Annual Calendar Chronograph, and the Nautilus Travel Time Chronograph (prices are included). Patek Philippe has released a new stainless steel model of its Annual Calendar Chronograph (Ref. 5960/1A-001), which was first introduced in 2006 in a platinum case, with subsequent editions’ cases in other precious metals. Patek Philippe rarely makes watches in stainless steel, outside of its sportier Nautlius and Aquanaut collections, so the new Annual Calendar, which contains the automatic caliber CH 28-520 IRM QA 24, will strike many Patek aficionados as something of a surprise. The masculine dial conveys a sense of depth with its applied hour markers, applied blackened-gold frames for the calendar windows (day, date, and month), and blackened appliqués for the chronograph scale and 12-hour scale. Black is also used for the faceted hour and minute hands (which are coated with Super-LumiNova), the 12-hour counter hand, and the power-reserve hand, and a bright signal red distinguishes the central chronograph seconds hand and the hand for the 60-minute counter. The model’s “monocounter” subdial has been reconfigured, with the 12-hour counter scale on the outside and the 0-to-30-minute and 30-to-60-minute scales in the middle and inside, respectively. Caliber CH 28-520 IRM QA 24, which is equipped with column wheel and disk clutch, also powers a day/night indicator at 6 o’clock. The Patek Philippe Annual Calendar Chronograph Ref. 5960/1A has a stainless steel bracelet with droplet-shaped links and a stainless steel fold-over clasp. The price is $54,800.

Another new Patek Philippe watch comes from the aforementioned Nautilus family of luxury sport watches. The Patek Philippe Nautilus Travel Time Chronograph (Ref. 5990/1A-001) is a modern reissue of a cult classic Patek Philippe chronograph watch from 1976 that also, for the first time in Patek’s portfolio, combines a chrono with a dual-time-zone function.

To maintain the contours of the classical Nautilus case, the two correctors that adjust the time zone up and down in one-hour increments are seamlessly integrated into the case flank at 9 o’clock. Patek Philippe also shifted the two chrono pushers closer to the crown for greater ease of use. The black dial, with the brighter-to-darker gradation and horizontal embossed pattern, now features day/night indicators for both time zones, a date subdial at 12 o’clock, and a 60-minute subdial at 6 o’clock for ideal legibility. The all-new automatic movement that powers all these complications, Caliber CH 28-520 C FUS, is visible through the sapphire caseback. The Nautilus Travel Time Chronograph Ref. 5990/1A has a stainless-steel bracelet with fold-over clasp. Patek says that the new model will replaces the Nautilus Chronograph 5980/1A, launched in 2006, in the collection. The watch will be priced at $57,300.
