Alpiner Extreme Skeleton Automatic AL-520GSKT3AE6B Watch

The Watch

Alpina is a Swiss brand founded in 1883 in Geneva. Rooted in precision, durability, and innovation, it has evolved with the times while staying true to its heritage. Built to withstand the most extreme conditions, Alpina watches combine rugged performance with refined contemporary style. Inspired by mountaineers, the brand has been crafting sport watches that accompany aviators and divers alike for decades. From its Alpiner collection, it presents this compelling Extreme Skeleton AL-520GSKT3AE6B Watch in a total grey look. The cushion-shaped case features a fixed bezel with 6 screws and is crafted from 316L stainless steel with a brushed and polished finish. It measures 40.40 mm in length, 39 mm in width, and 11.50 mm in thickness, weighing 98.30 g - dimensions perfectly suited to men's wrists. The flat sapphire crystal with anti-reflective coating offers exceptional scratch and shock resistance, keeping the dial protected at all times. A screw-down crown at 3 o'clock makes setting the hands intuitive. The screw-down caseback delivers water resistance to 20 ATM, while its display glass offers a captivating view of the movement.

The Dial

The dial on this model is a showstopper, thanks to its skeleton design that puts the movement's inner workings on full display. Its grey tone is complemented by a matte finish that adds to its rugged charm. A minute track runs along the outer rim for easy time reading. The baton indices and the two central hands for hours and minutes are coated with SuperLuminova C1 for enhanced dark-environment legibility. A slender seconds hand with a red tip completes the layout. The brand places its name at 12 o'clock as its signature.

The Movement

This timepiece is powered by a Swiss-made automatic movement - specifically caliber AL-520 on a Sellita SW200 base, beating at a frequency of 28,800 vph. It features 26 jewels and a power reserve of 38 hours.

The Strap

This men's watch is paired with an H-link bracelet in 316L stainless steel. Its silver tone and brushed finish give it a sleek, polished look that works with any style. The lug width is 24.80 mm and the bracelet length is 174 mm. It fastens securely with a push-button deployment clasp.

Water Resistance

This model offers water resistance to 20 atmospheres, or 200 meters. Built for deep-water adventure, it's rated for freediving - and tough enough to withstand high-pressure cleaners without breaking a sweat. Shower, bath, lap swimming, and freediving are all no problem. For scuba diving with tanks, however, we recommend a timepiece with a higher water resistance rating. Also, avoid operating the crown while submerged to protect the movement's integrity.
