This is a near-perfect example of the so-called “linen” dial tri-compax by Universal Geneve. It features a bright, silver linen-look dial, and their trademark twisted lugs/bombay-style case.
This example happens to be in great condition, with a thick, mint and unpolished case. The dial is immaculate. The serial/reference numbers are faintly visible on the caseback with a loupe, and not completely gone.
