In order to celebrate Portuguese 75 anniversary, IWC launches new perpetual calendar watches and chronographs among the Portuguese series, and will be display in the coming SIHH in future days. Before that we have briefed you on the perpetual calendar, and navigation watches, and today we have a different Portuguese Perpetual Calendar. It is fitted with a double moon phase (Ref.5034 and Ref.5033) that adds fresh blood to Portuguese series.

In 1999 and 2009, IWC released 3527 and Acquatimer 3547, and it released the third edition of the former two: an Aquatimer IW355701, that cold reflect IWC’s rich experience in developing new watches. It can be used to measure the diving time, and three different rotating bezels shows that IWC has been keeping updating its system. GST Aquatimer has an inner bezel that could be adjusted by the crown at 2 o’clock. This new technology can completely avoid false operation on the crown. what’s more, under the mirror, this is the luminous layer that could resist water and scratch. But when you wear gloves or under the dark situation, the crown is not as easy to operate as you moving the crown. So in the 2009 Aquatimer, IWC chose the outside bezel so that it could be easy to operate even you wear heavy glove. For the consideration of safety, you can only do the left-rotating. The bezel is made of multiple components, and there is an inner inserted sapphire ring whose bottom is coated with Super-LumiNova—luminous layer.

To meet more requirements on material for the replica watches quality, IWC has three types for choice for its new works of Portuguese Yacht Club Chronograph: the 18k red gold edition with silver dial, the stainless edition with silver-guilt dial, and the third stainless steel with radiation patterns. IW390503 is a powerful movement which has 68 hours of energy reserve and works at a frequency of 28,800 times per hour. It displays hour, minute, hand, and date. A folding buckle making more flexible and secure.
