A titan of aviation heritage, the Laco 55 mm B-Uhr “Type 1” homage faithfully channels the spirit of the original Beobachtungsuhr worn by Luftwaffe navigators during World War II. This imposing timepiece, brimming with historical character and technical detail, is presented today in excellent, near-mint condition and includes its full accompanying set.

Inside beats a robust mechanical movement, surrounded by an iron core for magnetic protection—just like the originals—capable of hacking for precise time setting. The crown is designed in the traditional “diamond” or onion shape, oversized for operational ease even when worn over flight-gloves.

Supplied on a long, riveted leather pilot strap designed to fit over a flight-jacket sleeve, this Laco B-Uhr also comes with its original wooden box and paperwork. It captures the scale, authenticity, and mechanical spirit of the 1940s navigators’ tool watches but delivers it in near-mint condition today.The case measures 55 mm in stainless steel with a open back case. The dial is matte black Type 1 with blued hands and large legible markers. The crown is oversized and diamond-shaped, and the watch is mounted on a long riveted leather strap suitable for over-sleeve wear.

This Laco Beobachtungsuhr is limited n umber 155/500 and comes as a full set and is in near mint condition!
