Blancpain Leman Tourbillon Semainier

The prime qualities one expects from horological complications are mechanical complexity, user-friendliness and useful information.

These three criteria are fully met by the Tourbillon Semainier in the Leman collection, born from the know-how of the master-watchmakers of the Manufacture in Le Brassus. This unusual combination of complications beats to the rhythm of the new Calibre 3725G and its 356 components.

Taking account of the busy contemporary reality, the Tourbillon Semainier in the Leman collection is a concentrated blend of the “tradition of innovation” philosophy consistently applied by the Manufacture in Le Brassus. This combination of horological complications, unusual for the brand, merges tradition with contemporary requirements.

It draws upon the know-how cultivated by the master-watchmakers of the venerable house in order to offer a new complex caliber providing indications that are useful in everyday activities and meet the demands of an active lifestyle.

In addition to showing the hours, minutes and seconds, the power-reserve and featuring majestic flying tourbillion placed at 12 o’ clock, the newcomer to the Leman collection also displays the the day of the week, the date (Grande Date) and the week of the year.

Much appreciated in today’s world, the later item of information is indicated by a central hand pointing to one of the numbers appearing around the rim of the dial. Its numbering from 1 to 53 serves as a reminder that some years have 53 weeks according to official schedules; this will be the case in 2009 and then in 2015, 2020 and 2026, to mention only the nearest dates.

To give life to this mechanical dance of time, the master-watchmakers of the Manufacture have developed the new caliber 3725G, a mechanical self-winding tourbillon movement with a 7-day power-reserve.

This spectacular embodiment of ingenuity comprises 356 parts. As one would expect from Haute Horlogerie creations, Blancpain’s master-craftsmen perform the delicate finishing operations- bevelling of the bridges and plates, the Cotes de Geneve decorations and circular graining-entirely by hand.

The Blancpain Tourbillon Semainier watch comes in a case with a 40mm diameter for enhanced legibility, crafted in 950 platinum with a black dial or in 18-carat red gold with a opaline-white dial.

Its water-resistance is guaranteed to 100 metres and its sapphire crystal case-back enables one to admire the finishing work lavished on all the components.

The black or brown crocodile leather strap is fitted with a platinum or red gold folding clasp.
