Omega Trench Watch from the 1910s (World War I era). Rare numbered protective grille!!!!! This timepiece is an iconic milestone in horological history, beautifully representing the transition from pocket watches to the very first wristwatches worn on the battlefield. Key Features: • Period: 1910s (WWI) • Movement: Genuine, period-correct Omega mechanical manual-wind caliber • Case Material: Robust, military-grade steel case with characteristic fixed wire lugs • Case Size: 35 mm (excluding crown). This diameter is exceptionally large and rare for trench watches of this era, making it perfectly wearable by modern standards. • Case Authenticity & Supplier: The case features no external or internal brand markings, which is entirely correct and authentic for non-precious metal military cases of this period. During the war, Omega primarily supplied the movements, while the functional steel cases were provided by renowned contemporary specialists such as Dennison, Borgel, or Huguenin Frères (HF). This lack of marking is a textbook characteristic of genuine wartime steel military issues. • Dial: Beautifully and professionally restored military dial with bold Arabic numerals and a sub-second subdial at 6 o'clock. Thanks to the high-quality restoration, the watch is in stunning, collector-grade aesthetic condition. • Condition: Period-correct, running condition with a beautiful vintage patina. • Strap: Period-accurate, military-style leather strap. Target Audience: Ideal for vintage watch collectors, military horology enthusiasts, and WWI memorabilia
