Founded in 1883, Alpina turns 140 in 2023, and in honour of the occasion, the Swiss watchmakers are unveiling a timepiece that revives their illustrious heritage. This isn’t some re-edition or a piece inspired by a predecessor: it really is the original, made in 1938. Alpina has unearthed two 14-piece series of the authentic Calibre 490, released exactly 85 years ago; only a very few of these are still in existence.

The fully-restored movements, dubbed Heritage Carrée Mechanical 140 Years, have been housed in a rectangular silver case in tribute to an outstanding wristwatch in Alpina’s history. One series features a black dial, the other a silvered dial. The feeling when you behold a perfectly-finished, rectangular-shaped movement with a sedate frequency (2,5 Hz), already fitted out with early levels of protection against water and dust, is indescribable. These are two highly limited editions, produced for History.

A HIGHLY ACCOMPLISHED MOVEMENT

Back in 1938, the Calibre 490 already embodied Alpina’s emerging vision.

It features a patented crown incorporating protection against dust – an key milestone, already making the case airtight and a first step on the way to the watertight case that would later become standard.

The movement, protected by Swiss registered patent no. 158882, is characterised by a simple, robust construction but no less perfectly finished for that: all of its components are bevelled, and the ratchet is sun-brushed.

It’s also worth noting that this is a genuine in-house calibre, designed, assembled and finished by one of the firms in the Union Horlogère, Alpina’s original entity – a particularity seldom seen in the 1930s when generic ébauches (movement-blanks) were the market norm and manufacture movements the exception.
AN AVANT-GARDE CONSTRUCTION

It’s a shaped movement in the finest watchmaking tradition, according to which the movement should reign supreme, dictating the shape of the case rather than the other way around.

Hand-wound like almost all calibres of its day, it comprises 17 jewels and oscillates at 18,000 vibrations per hour, the standard frequency for Thirties timepieces. Its 42-hour power reserve is notably capacious for its time; another distinctive feature is the slender anchor design required to fit within the rectangular layout of the Calibre 490.

Back in the day, the case was made from steel or gold depending on the model. One steel case was itself protected by a patent (No. 207378) and described as being ‘stainless’, offering further evidence of Alpina’s obsession with making its timepieces resistant to wear and tear.
CLAD IN SILVER

Today, Alpina has designed a new bespoke case to house its Calibre 490, naming the new model after it: Heritage Carrée Mechanical 140 Years. Made from mirror polished silver, it measures 29.5 x 35.7mm. With a thickness of just 9.71 millimetres, it features an anti-glare sapphire crystal on both front and rear, through which the venerable beauty of the period Calibre 490 can be admired. The timepiece comes on a light brown ostrich leather strap, with vintage white stitching and pin buckle.

Two variations of the piece are available, each in a limited edition of 14. Both feature Alpina’s period logo, two slim central hands and the small seconds hand display at 6 o’clock so typical of the 1930s. A ‘railtrack’ minute circle, also typical of the period, runs around the dial. On one version the dial is black with solid Arabic numerals, accompanied by beige hands and a circular small seconds hand display. The other version sports a silvered dial, black hands and the squarer outline Arabic numerals favoured in the Roaring Twenties, along with a square small seconds hand display.
