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.

Au­to­matic move­ment beat­ing at 4Hz, with two bar­rels and power re­serve in­di­ca­tor (seven days) Di­men­sions: 37.8mm x 7.5mm Num­ber of parts: 257
