Housed in a 40 mm round 18kt white gold case measuring 11.36 mm thick, the 5205G-013 features a fixed white gold bezel, a transparent case back, a pull/push crown, and water resistance to 30 meters. The blue alligator strap fastens with a tang buckle and measures 20 mm at the lug.
The blue sunburst dial is fitted with white gold hands — luminescent for low-light legibility — and index hour markers, with minute markers tracing the outer rim. Displays are arranged across the dial: date at 12 o'clock, day of the week at 10 o'clock, month at 2 o'clock, and a combination sub-dial showing 24 hours alongside an inner moonphase. A scratch-resistant sapphire crystal completes the presentation.
Power comes from the Patek Philippe calibre 324 S QA LU 24H/206 automatic movement, a 34-jewel manufacture with a power reserve of between 35 and 45 hours. Functions include hours, minutes, seconds, date, annual calendar, moonphase, and 24-hour display. This example is offered in pristine condition and includes the original box; original papers are not included.
