A very rare Omega trench watch from the First World War.
Large 42 mm watch with no protruding parts. The last photo shows a regular size 35mm watch for comparison (not included in the lot).
Cupronickel silver case with hanging lugs in art deco style.
Mineral glass.
The mechanism is high-quality gold-plated with 15 stones.
The enamel dial has small cracks (visible through a magnifying glass) and a chip in the enamel between the numbers 11 and 12 (restored, hidden under the bezel and not noticeable).
Approximate year of manufacture: 1915.
I will answer all questions.
