IWC CALIBRE 52010
ven among storied brands, IWC stands out for how deeply it has written itself into watchmaking history. Timepieces for air force pilots just as air power was gaining traction among military planners, watches for scuba diving, timepieces for engineers as we turned a corner into the modern technological age – individuals engaged in pushing boundaries on land, in the air, and under the sea need wristwatches and IWC has enriched its own heritage and knowhow by making purpose-built wristwatches for them. For a dressier pick, the Portugieser is among the most iconic and best loved. The original introduced in the 1930s was borne from the need for a marinechronometer grade wristwatch, then only possible by casing a large, high-quality pocket watch movement in a wristwatch case.
This collection has been characterised by large cases and IWC’S largest movements ever since, including 2000’s Portugieser Automatic with a 50000-calibre movement that boasts seven-day power reserve and a highly efficient Pellaton winding system. The calibre 52010 featured here is a 2015 update with further technical enhancement and better finishing. Ceramic parts have been added to the winding system, making it virtually impervious to wear and tear; the faster balance now beats at 4Hz for better accuracy. Moreover, 52010 has two mainspring barrels to supply the same seven days’ power reserve with greater consistency for improved chronometry. IWC also partly skeletonised the rotor so the improved finishing of the movement is more readily evident.
