This is a well-preserved circa WW2 era vintage watch made in Switzerland by MENTOR watch company. The 15 jewel movement is accurate after a very recent cleaning. The completely original two tone dial is truly awesome with its salmon and white colour scheme. The simple hands are thin and elegant in blued steel. The steel case measures a respectable 36mm. but looks larger due to the narrow and almost non-existent bezel. This watch is also very thin at just under 9mm. This watch has fixed lugs, leading me to believe it was designed for WW2.
