This is a Longines Sei Tacche reference 5697, featuring a classic military-style black dial with Arabic numerals. The crystal shows a small crack, but it has been left untouched to preserve the originality and character of the watch.


The stainless steel case measures 34mm and remains in excellent condition, with only minor tool marks visible on the caseback. Both the caseback and lug are stamped with the same three-digit number, confirming its originality. The internal retaining ring is intact, adding to the completeness of the piece.


As part of Longines’ Sei Tacche line, this watch carries the brand’s early waterproof case design of the 1940s, developed for durability and reliability in demanding conditions. It comes on a high-quality distressed leather strap that complements its vintage military character.


Bid with confidence, we have been selling on eBay for 20 years. If for any reason the watch is grossly misrepresented, return addresses are available in the US, Canada, Spain, Germany, and UK, to ensure a hassle free return.
