There are four crowns on one watch, which are responsible for starting the alarm, winding, and adjusting the local time and the time in two places. The new model adopts a "two-color" design: a gray sunburst dial with charcoal gray and white gold three-dimensional Arabic numerals and sword-shaped hands. It uses the automatic winding AL 30-660 S C FUS movement. Best cheap watches online, discover our affordable replica Patek Philippe watches collection. Wide range of luxury watches brands.

Generally speaking, the function of the alarm watch is to serve as an alarm clock, and the sound is relatively harsh, while the Patek Philippe 5520 uses the time-telling sound of a minute repeater, which is very pleasant. First of all, the design of displaying 24 time zones on the dial at the same time was used. Patek Philippe Swiss patent CH699785 was applied on October 23, 2008, and the inventors were PASCAL HUMAIR and PHILIPP BARAT. The current time zone and the home time zone (Home Zone) are displayed on the dial at the same time. The problem solved is to quickly adjust the calendar of the two places. As the time difference is adjusted during travel, the date display will also change. For example, the time difference between Beijing (Eastern Zone 8) and Zurich (Eastern Zone 1) is 7 hours. On the 2nd, the Beijing time is 6:00 a.m., and the local time in Zurich is 23:00 on the 1st. If the dual-time watch is adjusted back by 7 hours, the date will also change, including the local time wheel (36) corresponding to the first time zone, the local time wheel (42) corresponding to the second time zone, and the date display mechanism (44, 96, 100, 112, 58, 28), characterized in that the date display mechanism (44, 96, 100, 112, 58, 28) is driven by the local time wheel (42).

The invention realizes a two-time alarm clock, using the Swiss patent "CH709069 Clock including a striking mechanism associated with an adjustable time zone mechanism", which includes a movement having an hour wheel (27); a striking mechanism capable of striking at least the hour, including an hour snail (22) coaxial with and integral with the hour star (21); a mechanism for changing the time zone, which includes a time zone selection member (1), characterized in that the hour star (21) and the hour lymason (22) are driven by a gear return. The hour star (21) is meshed with a coaxial time zone wheel (28) and is connected to the hour wheel (27) of the movement through a coupling, so that these wheels can be gradually shifted relative to one another.
