Alpina Sea Strong

A striking and increasingly collectible 1970s Alpina Sea-Strong automatic, featuring the distinctive tonneau/cushion case design that perfectly captures the style of the era.

Powered by a reliable Swiss ETA automatic movement and displaying both day and date, this watch combines vintage character with everyday practicality. The original dial has developed a beautiful speckled patina over time, giving the watch a unique appearance that cannot be replicated.

The watch remains in good honest vintage condition.

The dial has developed a uniform speckled patina throughout, giving it considerable vintage charm and individuality.

The case shows normal wear, scratches and marks consistent with age and use, but retains its original shape well. The crystal remains clear with only light wear visible.

Overall, this is an attractive, unpolished example with plenty of vintage character.

Running well and operating as intended.

The automatic movement winds smoothly, the day and date function correctly, and the watch is keeping time. The ETA-based movement offers good reliability and ease of servicing compared with many lesser-known vintage calibres.

The Sea-Strong line represents Alpina's move into the bold styling of the 1970s while retaining traditional Swiss mechanical quality. Vintage Alpina watches have become increasingly sought after in recent years, particularly unusual cushion-case models and examples powered by ETA automatics.

A characterful and increasingly collectible Swiss automatic from one of Switzerland's historic watchmakers.
