Simple And Practical Iwc Portuguese Series Annual Calendar Watch

Last year was an exciting year for IWC fans. The 75th anniversary of the iconic Portuguese collection launched a number of new Portuguese watches, making many improvements in technology and aesthetics. And equipped with new features. The self-produced 52000 series movement developed by the brand is also fully equipped in the models of the new Portuguese watch series.

   IWC has never had an annual calendar watch, and the introduction of this watch has made up for the gap between IWC and the simple date display. The movement is the latest Cal.52850 self-developed movement developed by IWC. It is equipped with two barrels, which can provide a 7-day power reserve on the winding chain. The annual calendar itself is also a very practical and super cost-effective function.

   This new calendar model (model: IW503504) is equipped with a 18K red gold case with a diameter of 44.2 mm and a silver-plated dial. There are three independent semi-circular windows above the dial to display the month, date, and week, respectively, and its switching mechanism has automatically taken into account the different days of each month. Unlike the perpetual calendar, the calendar does not consider the number of days in February or the impact of leap years. Therefore, it needs to be manually adjusted at the end of February every year. It is simple and convenient to adjust the crown.

   Double-sided anti-reflective domed sapphire glass with silver-plated dial. The design of the small three-hands, the power reserve slot at 3 o’clock displays the red gold small hands, and the red gold small seconds hand at the small seconds at 9 o’clock. Foreign aid track-type minute scale and Arabic numeral hour display. The layout is neat and easy to read the date and time.

   The display design of the annual calendar is concise and neat. Three independent semi-circular windows display the month, date, and week, respectively, and are set between the scales of 11:00 to 1:00.

   18K red gold screw-in gear crown, Portuguese series’ consistent crown shape, the top of the crown is engraved with the brand’s English logo.

   The black crocodile leather strap is neatly textured, and the black hand-stitched stitching is even more delicate. The red gold folding buckle is easy to wear, and the brushed buckle handles and is engraved with the IWC brand logo.

   The thickness of the side is 15.30 millimeters. It is moderate to wear the IWC. The grooved bezel and the side of the case are brushed to maintain the Portuguese style.

   The lugs also continue the IWC’s usual style, with natural radians, polished and polished on the front.

   The sapphire is transparent, and the exquisite movement is clear at a glance. Equipped with a new Cal.52850 self-winding movement, no-adjustment Glucydur® balance balance, fine adjustment screws and Breguet balance springs on the rim of the balance, and 18K gold badge on the rotor. The movement is equipped with two barrels to provide more torque to drive three display discs. In addition, after winding, the dual barrel can provide enough energy for the watch’s power reserve for up to seven days.
   The adjustment of the annual calendar function only needs to be adjusted through the crown. The hour wheel in the movement pushes the date advance wheel. The date advance wheel has two different advancement pointers, one of which is responsible for advancing the date and month, and the other is for displaying the week. Whenever it is midnight, the date can be converted with the help of the upper pointer. The month display and the setting wheel for adjusting the length of the month are controlled by two pins in the date display. The first pin on the display dial advances the setting wheel by one revolution. A stylus on the pusher lever uses a deeper cutout on the setting wheel to identify the 30-day month, setting a longer switching route for it. In this way, the double conversion of the date can be achieved the next day through the push rod.

In summary: this annual calendar watch is also a watch of historical significance for IWC. The annual calendar function is very practical, and it is very convenient and simple to adjust it by a single crown. I believe that the price will also be reasonable after listing and the cost performance is very high. The simple and neat dial design is elegant and beautiful, suitable for any occasion.
