Blancpain Léman Only Watch 2005 Unique Piece

This unique Blancpain timepiece was created especially for the Only Watch 2005 charity auction.

Under the guidance of H.S.H. the Prince Albert II of Monaco, “Only Watch” is an outstanding charitable auction established by Luc Pettavino, founder of the United Parent Project Muscular Dystrophy (UPPMD) and president of the “Association Monégasque contre les Myopathies” (AMM).

The proceeds of this charity event benefit the “Association Monégasque contre les Myopathies”, the organization created by parents of children with Duchene’s Muscular Dystrophy.

The “Only Watch 2005” event took place on 22 September 2005 in the Principality of Monaco, during the internationally-renowned MONACO YACHT SHOW.

For the Only Watch 2005, Blancpain created a self-winding timepiece from its Léman collection, limited to an edition of one, in brushed red-gold with an astounding sapphire dial, and a large-date display on two, rhodium-plated date-discs located at 6 o’clock.

The unique Léman Only Watch 2005 offers an unimpeded view of the hand-assembled, hand-decorated 285-component, self-winding Blancpain Calibre 6950A. Thanks to a sapphire dial and case-back, the movement’s exceptional, meticulous finishing has been made astonishingly visible. This movement provides a 70-hour power reserve once it is fully wound.

To ensure maximum visibility of the interior workings of this unique wach, Blancpain used a sapphire dial. The dial plate, just 0.6 mm thick, has been drilled in 25 specific locations for mounting the baton and Arabic-numeral hour-markers, as well as for affixing other functional and ornamental elements. The rims of the two date-windows have been transfer-pressed into the sapphire to allow greater legibility. The Superluminova-tipped cone-shaped hands add both readability and panache to the watch.

The Léman Only Watch 2005 watch has a brushed, red-gold case measuring 40 mm in diameter. Fitted with sapphire crystal, screw-down crown and case-back, it is water-resistant to 100 metres.

Aside from the large-date display, time is indicated via both luminescent baton markers and Arabic numerals at 12, 3 and 9 o’clock, and centre, cone-shaped hour, minute, and seconds’ hands.

On the underside of the watch, the blued Blancpain signature has been engraved on the oscillating weight, N°1/1 and the usual Léman signature have been engraved on the case-back, and traditionally-heated blued screws share the limelight on the underside of the movement.

The Léman Only Watch 2005 features a rubber strap and folding clasp in brushed red-gold.

Thanks to the transparent dial, the Calibre 6950A is displayed in all its grandeur, with its hand-adorned Côtes de Genève, its fine circular graining on the plate and its sunburst, snailed finishing on the two wheels carrying the tens and units of the date display. The Only Watch and Blancpain distinctions have been engraved and galvanised in red-gold on the dial-side.
