The Longines Sei Tacche of 1944 sits at an interesting intersection of horological history and practical design. In the 1940s Longines wasn’t just producing watches for everyday wear, it was supplying timepieces that had to perform reliably through the turbulence of a world war. The sei tacche name refers to the six notches around the screw-back case, a design detail that evolved as wristwatch cases shifted from simple snap-backs toward more robust, moisture-resistant constructions. Collectors today use the Italian expression “tre tacche” and “sei tacche” to distinguish between three-notch and six-notch screw-backs on vintage Longines production.

This example embodies that heritage without overstatement. The 33mm stainless steel case has patinated in a way that feels appropriate for a watch of its age. The manual-wind calibre 23M, serviced and running well, was built to be dependable, and this movement architecture was part of what helped Longines build its reputation for precision both in military contracts and among civilians looking for a rugged everyday watch.

Where this watch becomes particularly engaging is in the dial and hands. The factory original silver dial has mellowed into a subtle yellow-green patina, a mark of age that enhances rather than obscures its character. Instead of only a conventional 12-hour scale, this dial presents a full 24-hour indication, something that made sense in military and navigational contexts where distinguishing morning from evening at a glance could be important. The radium-filled Arabic numerals and blued-steel pencil-style hands are honest to their period and still read with clarity that belies their years.

On its period-correct reproduction 16mm military style strap with a gold buckle, the watch presents with a presence that feels right for its purpose. There’s no pretense here, just a snapshot of mid-century watchmaking that speaks as much about utility as it does about aesthetic restraint. For anyone interested in Longines history or in the evolution of functional watch design through an era of global upheaval, this piece is a compelling conversation starter.
