Starting with the Iwc Watches Edinburgh Replica Big Pilot’s Watch Heritage, the newest piece is quite similar to previous Big Pilot’s Watches together with the exclusion of case material, that is now either bronze or titanium, and the addition of the very striking IWC 52110 in-house manufacture caliber. The normal Big Pilot’s 51111 quality features more stones at 42 but defeats in a significantly slower 21,600 vibrations per hour (3Hz). The 46.2millimeter case, touch crown, and vintage inspired leather strap stay similar in fashion to previous Big Pilot’s. For anyone with more routine wrists and bank account, IWC also have generated the Mark XVIII at a special Heritage edition. The brand new IWC Pilot’s Mark XVIII Heritage keeps the aviation fashion dial and hands as well as the small 40mm case size from previous models. New is the use of titanium as a case substance which gives the piece a pragmatic texture in addition to a much lighter overall weight. The addition of IWC’s 35111 caliber also distinguishes this new model from it is forebears and while it isn’t a totally in-house grade like those in the Heritage Big Pilot’s, it’s still a competent 25-jewel motion based on the Sellita SW300 as opposed to the 21-jewel, ETA 2892 base movement found in the normal IWC Mark XVIII. A marginally less striking caliber such as the 35111 with a more approachable 42-hour power book also helps to keep the price somewhat reasonable.
The Portofino line is mostly made up of simple, affordable watches, but IWC just made it a bit fancier with the addition of the Portofino Hand-Wound Tourbillon Rétrograde, the very first tourbillon in the collection named after the Italian resort town.
A large 45mm in diameter and available only in 18k red gold, the tourbillon is powered by the cal. 59900. Related to the cal. 89900 found inside the Da Vinci Tourbillon Retrograde Chronograph launched earlier this year, the new calibre is hand-wound movement with an eight-day power reserve, thanks to an extremely large barrel visible through the display back. The bridges have been open-worked to reveal some of the mechanics, including the gear train and keyless works.
Just like the movement inside the more complex Da Vinci, this is equipped with an unusual hacking tourbillon. When the crown is pulled to set the time, a pair of levers stop the balance wheel, allowing for more precise time-setting. Having been invented by A. Lange & Söhne, the stop-second tourbillon is still a novelty for IWC.
Additionally, the pallet fork and escape wheel are made of diamond-coated silicon (the diamond coating hardens the surface and reduces silicon’s sensitivity to temperature changes), significantly improving their efficiency by reducing friction and mass.
On the front the flying tourbillon is visible at six o’clock, with the retrograde to its left and a power reserve on the right.
