A tank watch has a rectangular case, not round.

A gift to my father from one of his friends, who passed it on to me. Up until I got it, I had no idea Omega made tank wristwatches; I was only familiar with the big Oysters and Speedmasters and such. Big, heavy, watches with big dials.

This is small and elegant, very thin and featherweight. It's hands down the best watch that I own; also the only Omega that I own that's legitimate. I wear it with a shirt that has french cuffs.
