Blancpain’s L-evolution Collection, which debuted at Basel in 2009, expands this year with a new long power reserve complication, the L-evolution Semainier. Powered by an in-house automatic winding movement with three mainspring barrels and a titanium free-sprung balance, the L-evolution Semainier offers week of the year, large date, day of the week and power-reserve indications in addition to its extraordinarily long 8-day power reserve.
