Alpina Alpiner Extreme Automatic Military Watch
Starting from 1.695 €The Alpina Alpiner Extreme Automatic 39 mm is a Swiss sports watch built for the outdoors, a direct descendant of the Alpina 4 philosophy born in 1938 to equip mountaineers, pilots and soldiers. Offered in five references and five dial variations, it features a compact 39 x 40.5 mm cushion case in 316L stainless steel, water-resistant to 200 metres and powered by the automatic AL-525 calibre. Its design, both square and round, its round bezel with six visible screws and its embossed triangular motif make it instantly recognisable. Priced under €2,000, this versatile tool watch is aimed at fans of rugged, legible, Swiss Made timepieces equally at home in the field and in everyday urban life.
Alpina Alpiner Extreme Automatic 39 mm military watch
Founded in 1883, Alpina ranks among the earliest major Swiss watchmakers. From the 1920s onward, its watches were distributed through more than two thousand points of sale, buoyed by a reputation for mechanical reliability and in-house production. The decisive turning point came in 1938, when Jacques Hauser established the Alpina 4 concept, which set four mandatory criteria for a timepiece to earn the title of sports watch: antimagnetic, water-resistant, shockproof and fitted with a steel case. This demanding specification for its time made the Alpina 4 the watch of choice for mountaineers, air force pilots, divers, the navy and the army. Production is now carried out at the brand's Geneva manufacture.
The Alpiner Extreme carries this heritage forward in a resolutely contemporary idiom. Redesigned in 2022 around a 41-millimetre cushion case, the line first appeared with a regulator dial, before expanding into hours-date versions and a chronograph. In October 2024, following an initial 39-millimetre trial with the Alpiner Extreme Skeleton, Alpina introduced the closed-dial automatic version in this compact format, better suited to slimmer wrists as well as daily wear.
The result retains all the character of the collection: three-piece construction, a round bezel screwed onto a square case, a protected crown, and a display caseback. Alpina positions this as a tool watch designed for the outdoors and the mountains rather than a strict diver, confirmed by the absence of a rotating bezel. It is aimed at fans of robust, technical, understated watches, drawn to a strong aesthetic signature and proven Swiss mechanics.

The Alpina Alpiner Extreme Automatic 39 mm sports watch
This Alpiner Extreme condenses all the collection's codes into a smaller format. The cushion case measures 39 x 40.5 mm for just 11.5 mm thick, a rare proportion for an automatic sports watch water-resistant to this depth. Its three-piece construction in brushed and polished 316L stainless steel combines a silhouette that is both square and round, topped by a round bezel with six visible screws echoing the brand's emblematic triangle. The finishing alternates vertical brushing on the bezel and lugs, circular brushing on the cushion's flanks, and mirror-polished bevels that catch the light along the edges.
The dial reprises Alpina's signature embossed triangular motif, with a satin finish that shifts depending on the viewing angle. The applied silver-toned hour markers are hand-polished and luminescent, as are the hands, ensuring immediate legibility in low light. A date window sits at 3 o'clock, while the red triangular counterweight seconds hand adds a graphic touch true to the house's identity. The screw-down crown, shielded by crown guards and fitted with a rubber grip matching the dial, can be operated easily even with wet or gloved hands. The whole is protected by a domed anti-reflective sapphire crystal, complemented by a display caseback that reveals the movement.
Five versions of one versatile timepiece
The Alpiner Extreme Automatic 39 mm comes in five references sharing the same technical base. At launch, three dials were offered: turquoise blue under reference AL-525TB3AE6B, fir green listed as British Racing green in the technical specifications, and rock beige. The first two are fitted exclusively with an integrated steel bracelet, while rock beige is available on both steel and an interchangeable beige rubber strap, the only version priced at €1,695. Alpina then rounded out the range with an exclusive glacier blue dial, reference AL-525LB3AE6B, presented as a luminous tribute to the alpine glaciers.
The steel bracelet measures 174 millimetres with a 24.8 mm lug width, designed as a continuation of the case for a cohesive silhouette. It closes with a push-button deployant clasp, a system also found on the rubber version, whose straps measure 75 x 115 millimetres. Mechanically, all versions run the AL-525 calibre, developed on a Sellita SW200 base and already used on the 41-millimetre model. This choice ensures straightforward servicing and proven reliability. With 200 metres of water resistance, this Alpina is built for outdoor use and surface water activities, without claiming diver status since it lacks a unidirectional rotating bezel.
Alpina Alpiner Extreme Automatic 39 mm military watch: compact toughness
The Alpiner Extreme Automatic 39 mm combines a 316L stainless steel cushion case measuring 39 x 40.5 mm, a slim 11.5 mm thickness and 200 metres of water resistance. The automatic AL-525 calibre, developed on a Sellita SW200 base, beats at 28,800 vibrations per hour, features 26 jewels and offers 38 hours of power reserve. The satin-finished triangle-motif dial carries luminescent applied hour markers and a date window at 3 o'clock, beneath an anti-reflective sapphire crystal. An integrated steel or rubber strap depending on version, a push-button deployant clasp, a display caseback and a two-year international warranty complete the package.
Movement
This Alpina is powered by the AL-525 calibre, an automatic movement developed on a Sellita SW200 base already used on the collection's 41-millimetre version. It totals 26 jewels and beats at 28,800 vibrations per hour, a classic rate ensuring smooth seconds-hand sweep and good rate stability. The 38-hour power reserve covers a full day off the wrist. The display remains deliberately simple: hours, minutes, seconds and a date window at 3 o'clock.
Diameter and materials
The three-piece cushion case measures 39 x 40.5 mm with a thickness of 11.5 mm, a compact format rare in this category. It is machined from brushed and polished 316L stainless steel, topped by a round bezel with six visible screws. The domed anti-reflective sapphire crystal protects a satin-finished triangle-motif dial, available in turquoise blue, glacier blue, fir green or rock beige. Vertical brushing, circular brushing and mirror-polished bevels play off each other across all surfaces.
Water resistance
With 200 m / 20 ATM of water resistance, the Alpiner Extreme Automatic handles swimming, water sports and outdoor activities exposed to water without reservation. This resistance relies on a screw-down crown, shielded by crown guards and fitted with a rubber grip matching the dial for easier handling. The display caseback reveals the movement without compromising the construction. The applied hour markers and luminescent hands ensure legibility in dark or submerged conditions.
Accessories
Depending on the version chosen, the watch comes on an integrated 316L stainless steel bracelet measuring 174 millimetres with a 24.8 mm lug width, or on an interchangeable beige rubber strap with 75 x 115 millimetre straps, reserved for the rock beige dial. Both options close with a push-button deployant clasp, secure and quick to operate. Alpina does not detail box contents on its product page; only the signed and stamped warranty certificate is mentioned in the official terms.
Warranty
Alpina applies its two-year international warranty to this model, valid through the brand's network of service centres. This coverage, described on the official website's dedicated page rather than the product sheet, requires presentation of a signed and stamped warranty certificate from the retailer at the time of purchase. It comes with an online activation procedure and access to technical manuals for mechanical models, making long-term servicing easier to track.
