The Alpina Alpiner Extreme Automatic Chronos Limited Edition AL-525CH4AE6B embodies Alpina's founding principles, the "4" concept, which means meeting the following characteristics: antimagnetic, shockproof, waterproof and with a stainless steel case. They are an excellent companion for sporting activities but also for everyday wear. This limited edition is made in only 140 pieces for the whole world. This number represents 140 years of the Alpina brand.
The steel case houses the AL-525 Swiss mechanical automatic movement (based on the Sellita SW200) with 26 jewels, which operates at a frequency of 28,800 semi-beats per hour and features a date display at the traditional position 3. The movement's operation can be observed through a transparent dial. The perfectly clear dial is protected by a sapphire crystal that is highly resistant to scratches. The anti-reflective coating ensures excellent legibility even in the harsh sunlight.
The AL-525CH4AE6B comes with a practical steel bracelet and, thanks to the 41 mm case diameter, fits perfectly on most men's wrists. The water resistance of this watch is 200m, so it can easily handle swimming or diving to about 20m. The water resistance is supported by a screw-down crown.

Alpina is again a step higher for us, a step among traditional watch manufacturers who are characterized by something innovative. Alpina's history dates back to 1883. Nevertheless, it remains a modern brand and the proof is the new models with smartwatches. Alpina has several watchmaking patents and its own solutions: Flyback chronograph, Tourbillon and the perpetual calendar. The brand is very nice to us with its sporty approach.
Helveti.eu is an authorized dealer and specialist of the Alpina brand.
