This year at Baselworld, Patek Philippe introduced two new versions of the Ref. 5396 Annual Calendar – which was previously only available with baton-shaped applied hour markers – with two new versions replacing the indices with Breguet-style Arabic applied numerals. One version is in rose gold with a silvery opaline dial (Ref. 5396R-012), and the other in white gold with a gray dial (Ref. 5396G-014).

The case has stayed the same at 38.5 mm in diameter and with a fully polished exterior, clear caseback, and 30 meters water-resistance.

The automatic movement, caliber 324 S QA LU 24H/303 movement, is also unchanged. It runs at 4Hz (28,800 vph), measures 33.3 mm/5.78mm, has 10 bridge, 34 jewels, 347 total parts, and a 45-hour maximum power reserve. The bridges are chamfered and polished, the mainplate is decorated with a perlage finish, and the regulation system features a Spiromax balance spring and Gyromax balance.

Functionally, everything is the same as well, with centrally mounted hours, minutes, and seconds – and a full Annual Calendar including day, date, month, and moon phases (with recessed pushers to adjust the calendar), which only needs to be corrected once per year in February. There is also a 24-hour display in the ring surrounding the moon phase at 6 o’clock.

As mentioned above, what is new, is the charcoal gray sunburst dial, and white gold applied Breguet numerals. The gray dial is particularly stunning, and as you can see in this image, it looks bluish-gray in certain lights. The rose gold model features rose gold numerals. Additionally, both versions have matching gold dots marking the outer minute/second ring. The hands are in polished gold, with Dauphine-shaped hands for the hours and minutes, and baton-shaped hands for the sweep second and 24-hour display.

Each of the new Annual Calendars comes with an alligator strap, including a toolless quick release lever, and fold-over clasp matching the case metal.
