YL factory IWC large-scale pilot series iw502708 perpetual calendar Dafei full real function large calendar timepiece men's watch .

YL's latest masterpiece V2 upgraded version IWC's 150th anniversary Geneva Haute Horlogerie Salon has launched several new products as one of IWC's most iconic series. This is the only new watch with a large calendar display window.

With a blue lacquered dial with exquisite craftsmanship and an iconic strap design (watch model: IW502708), it is equipped with a 2850 in-house movement, a Bieleton winding system with zero-wear ceramic parts, and is realized by a double barrel Power reserve function for 7 days.

It is also set off with a blue lacquered dial, plus the small seconds dials on both sides and the 7-day dynamic reserve indicator plate to make the dial of the new watch more harmonious and unique.

 Below the 12 o'clock mark are three almanac function windows, each presented in an American layout. Display month, date and week, only need to adjust once every year at the end of February.

The blue dial after the lacquer treatment is more of a quality atmosphere, blending with the rhodium-plated hands and the brand's classic pilot hour marker design, presenting IWC's characteristic aesthetic dial design. The hour and minute hands, the small second hand, the 8th dynamic storage indicator and the main time scale are all attached with a luminous part, which can observe the time even in a dark environment, which is convenient for viewing the time. The transparent back cover design, through the blue crystal glass back cover, you can see the beauty of the 52850 homemade movement. It is worth mentioning that this time the brand also gave the 150th anniversary gold coin to the stainless steel part of the back cover of the hollow rotor with the independent number of the watch engraved on it! YL ingenuity!
