TAG HEUER’S CAR­RERA MIKROGRAPH CEL­E­BRATES THE TECH­NOL­OGY BE­HIND SPORTS TIMEKEEPING

Virtuozity - - Watch -

TAG Heuer re­cently un­veiled the Car­rera Mikrograph chrono­graph, a spe­cial an­niver­sary edi­tion piece limited to just 100 ex­am­ples. The idea be­hind the watch, says TAG, is to rep­re­sent the al­liance of the rev­o­lu­tion­ary tech­nol­ogy and func­tional de­sign seen in the sports timekeeping in­stru­ments of the 1920s.

The large spher­i­cal ridged crown at 12 o’clock, framed by the char­ac­ter­is­tic “mush­room” push-pieces, is rem­i­nis­cent of the ear­li­est Heuer coun­ters. It fea­tures an au­to­matic chrono­graph dis­play­ing 1/100 of a sec­ond via a cen­tral hand, in­vented by Heuer in 1916 (11 patents). And there are two es­cape­ments os­cil­lat­ing at 28,800 vi­bra­tions/hour for the watch and 360,000 for the chrono­graph. All of this is pack­aged in a vin­tage de­sign in­spired by the sports chronome­ters of the era.

The white lac­quered dial sports black painted nu­mer­als and in­dices, a vin­tage Heuer logo and the in­scrip­tion “Made in Switzer­land”, faith­fully con­fig­ured as on the original model. Op­ti­mal leg­i­bil­ity.

Leg­i­bil­ity is en­hanced by the blued steel hands for the chrono­graph in­di­ca­tions, with a tear drop shaped coun­ter­weight on the minute hand and an ar­row on the counter hands. Rounded leaf-shaped hour and minute hands typ­i­cal of the Roar­ing ‘Twen­ties.

The an­niver­sary edi­tion TAG Heuer Car­rera Mikrograph vi­brates at the speed of a unique man­u­fac­ture move­ment first un­veiled to the world in 2011: the TAG Heuer Cal­i­bre Mikrograph 1/100 sec­ond. The first me­chan­i­cal chrono­graph with in­te­grated col­umn wheel dis­play­ing 1/100 of a sec­ond us­ing a cen­tral hand.

Pro­tected by 11 patents, this 480-com­po­nent cal­i­bre in­cor­po­rates two mech­a­nisms: one for the time, the other for the chrono­graph. Each has its own bar­rel and trans­mis­sion and es­cape­ment sys­tem. The first, for the watch (hours, min­utes, small sec­ond and date), os­cil­lates at a fre­quency of 28,800 vi­bra­tions per hour (4Hz), and has a power re­serve of 42 hours. The sec­ond, with an au­ton­omy of 90 min­utes, con­trols the 1/100 sec­ond chrono­graph.
