Overview

There are few brands in the history of watchmaking whose names are as deeply intertwined with military and aviation history as Longines. For decades, their timepieces were the benchmark for precision, legibility, and durability, becoming essential tools for pilots, navigators, and soldiers around the globe. This incredible piece, with its rare and functional 24-hour dial, is a stunning testament to that legendary heritage.

In military operations and exploration, avoiding ambiguity between AM and PM is not a matter of convenience—it can be a matter of life and death. This is why the 24-hour watch was developed. Instead of the hour hand making two rotations a day, it makes only one, providing an unmistakable reading of the time on a 24-hour scale. It’s a complication born of pure necessity. This watch is powered by a robust manual-winding Longines movement from the celebrated Calibre 12L family (12.68Z), a series of in-house calibers known for their superb quality and reliability. While the dial is pure military function, the handsome 10k gold-filled case suggests this was likely a private purchase for an officer or a commemorative piece, adding a fascinating layer to its story.

This specific example is, to put it mildly, a showstopper. The 32mm gold-filled case provides a warm and elegant frame for the main event: the dial. What was likely once a simple cream or silver surface has, over some 80 years, aged into a breathtaking landscape of texture and color. The patina is deep, speckled, and has taken on a gorgeous, warm champagne tone that is utterly unique. The full track of 24 Arabic numerals remains crisp and legible, as do the handsome blued-steel hands. The subsidiary seconds register at 6 o’clock provides a perfect visual balance. This is not just a dial; it’s a canvas painted by time.

Its condition is precisely what makes it so magical. This watch is a proud survivor, and it wears its history with honor. The case shows honest wear, but the dial’s patina is the star. This is the kind of authentic, earned character that modern watches can only imitate and that serious collectors actively hunt for. It is organic, beautiful, and tells a story of a life lived, all while the robust movement inside keeps ticking away faithfully.
