The Alpina Seastrong Diver Extreme Automatic Arkea Limited Edition AL-525NARK4AE6B watch embodies Alpina’s core principles, the "4" concept, which means meeting these characteristics: anti-magnetic, shock-resistant, water-resistant and with a stainless steel case. They are an excellent companion for sports activities as well as for everyday wear. This limited edition was made in honour of the ARKEA ULTIM CHALLENGE - Brest extreme yacht race. Only 100 pieces were made worldwide.
The steel case houses the Swiss mechanical automatic movement AL-525 (based on the Sellita SW200) with 26 jewels, operating at a frequency of 28800 vibrations per hour and featuring a date display at 6 o’clock. The perfectly clear dial, which bears the ARKEA ULTIM CHALLENGE - Brest race logo, is protected by a sapphire crystal that is highly resistant to scratches. The anti-reflective coating provides perfect legibility even in bright sunlight. The case back of these unique watches is marked with the route of the extreme race to which this limited edition is dedicated.
The AL-525NARK4AE6B model is supplied with a practical steel strap and, thanks to the 41 mm case diameter, fits most men’s wrists very well. The water resistance of this watch is 200 m, so it can easily handle, for example, swimming or a dive to approx. 20 metres. Water resistance is supported by a screw-down crown.
Alpina is the official timekeeper of the ARKEA ULTIM CHALLENGE - Brest extreme yacht race. This is a round-the-world yacht race that starts on 7.ledna 2024 and will last approximately 40-50 days. On an exceptionally demanding route, six competitors will sail from west to east around the Cape of Good Hope, Cape Leeuwin and Cape Horn. One of the participants is also Alpina brand ambassador Éric Péron, who will of course use the Alpina Seastrong Diver Extreme Automatic Arkea Limited Edition watch during the race. Éric Péron is a professional French skipper, an experienced captain and a participant in major yacht races with both team crews and solo sailors. He has raced on Olympic courses and has extensive experience from transoceanic voyages.
