Alpina Watch: Alpiner Extreme Solargraph Route du Rhum Destination Guadeloupe AL-140BT3AE6

Alpina: the Alpiner Extreme Solarmetre x Route du Rhum Destination Guadeloupe, a limited edition solar Extreme of 513 pieces

The Alpina Alpiner Extreme Solarmetre x Route du Rhum - Destination Guadeloupe AL-140BT3AE6 celebrates the 13th edition of the famous solo transatlantic race, for which Alpina is the Official Timekeeper. Limited to 513 pieces worldwide, it features the cushion case characteristic of the Extreme family in a compact 37.50 × 38.90 mm format. Its matte black, textured, translucent dial, turquoise accents, and black rubber strap give the Alpiner Extreme Solarmetre x Route du Rhum an identity directly inspired by the world of sailing.

The Alpiner Extreme Solarmetre x Route du Rhum uses a 316L stainless steel case only 10.19 mm thick, topped with a bezel featuring a carbon fiber insert. The matte black dial displays an Alpina triangular pattern and remains translucent enough to let light reach the solar cells underneath. A turquoise flange, a white minute track, and luminescent blue accents on the second hand and the triangular index at 12 o'clock add contrast to this Alpiner Extreme Solarmetre x Route du Rhum.

At the heart of the Alpina Extreme Solarmetre x Route du Rhum lies the Swiss Alpina AL-140 solar caliber, developed with La Joux-Perret. Natural or artificial light passes through the dial to recharge its integrated battery: one minute of exposure is enough to provide about one day of operation, while a full charge allows for up to 10 months of autonomy in total darkness.

The Alpiner Extreme Solarmetre x Route du Rhum is protected by an anti-reflective sapphire crystal and features a solid screw-down case back bearing an exclusive engraving of the Route du Rhum Destination Guadeloupe race course. Its textured black rubber strap extends its sporty and nautical orientation, while its water resistance of 10 ATM / 100 meters allows it to accompany daily use and various aquatic activities. The Alpiner Extreme Solarmetre x Route du Rhum thus combines Swiss solar technology, a compact format, and a true collector's appeal.

Why choose this watch?

The Alpina Alpiner Extreme Solarmetre x Route du Rhum - Destination Guadeloupe AL-140BT3AE6 combines four particularly strong arguments: a limited edition of 513 pieces, a Swiss solar movement offering up to 10 months of autonomy, a compact 37.50 × 38.90 mm format, and a sporty construction with sapphire, carbon, and 100-meter water resistance. The Alpiner Extreme Solarmetre x Route du Rhum also possesses a genuine identity linked to the race thanks to the engraved case back depicting its official course.

With its translucent black dial, turquoise accents, and textured rubber strap, this Alpiner Extreme remains sober enough to be worn daily despite its limited edition status. The Solarmètre technology in this Extreme x Route du Rhum also significantly reduces the constraints associated with replacing a traditional battery while maintaining the precision and simplicity of quartz.
